working principle:

The removal of organic pollutants and ammonia nitrogen from sewage treatment equipment mainly depends on the AO biological treatment process in the equipment . The working principle is in Class A. Due to the high concentration of organic matter in the sewage, the microorganisms are in anoxic state. At this time, the microorganisms are facultative microorganisms, which convert the organic nitrogen in the sewage into NH3-N , and use organic carbon as electron supply. The body converts NO2-N and NO3-N into N2 , and also uses a part of the organic carbon source and NH3-N to synthesize new cellular substances. Therefore, the A -stage pool not only has a certain organic matter removal function, but also reduces the organic load of the subsequent aerobic tank to facilitate the nitrification, and relies on the higher concentration of organic matter present in the raw water to complete the denitrification. Nutritional pollution. At the O level, since the organic matter has been greatly reduced, there is still a certain amount of organic matter and a high NH3-N . In order to further oxidize and decompose the organic matter, and at the same time, the nitrification can proceed smoothly under the condition that the carbonization is completed, and the aerobic biological contact oxidation tank with the lower organic load is disposed at the O level. There are mainly aerobic microorganisms and self-oxidizing bacteria (nitrifying bacteria) in the O -class pool. Among them, aerobic microorganisms decompose organic matter into CO2 and H2O ; autotrophic bacteria (nitrifying bacteria) use inorganic carbon produced by decomposition of organic matter or CO2 in the air as a nutrient source to convert NH3-N in sewage into NO 3-N , The NO 3-N , the effluent part of the O -stage pool is returned to the A - stage pool to provide an electron acceptor for the A -stage tank, and the nitrogen pollution is finally eliminated by denitrification.

main feature:

1. The sewage treatment equipment can be buried below the surface of the earth. The surface can be used as a greening or plaza land. Therefore, the equipment does not occupy the surface area, does not need to be built, and does not need heating and insulation.

2 , sewage treatment equipment consists of five-stage pool, using 4mm lining FRP , anti-corrosion life can reach more than 10 years.

3. The AO biological treatment process in the sewage treatment equipment adopts the push-flow biological contact oxidation tank, and its treatment effect is better than that of the fully mixed or the second- and third-stage series fully mixed biological contact oxidation tank. Moreover, it is smaller than the active sewage pool, has strong adaptability to water quality, good impact resistance, stable effluent quality, and no sludge expansion. At the same time, a new type of composite filler is used in the biological contact oxidation tank, which has a large specific surface area, and is convenient for microbial hanging and stripping. Under the same organic load condition, the removal rate of organic matter is higher than other fillers, and the oxygen in the air can be improved. Solubility in water.

4. Since the biological contact oxidation tank is produced in the AO biological treatment process, the volumetric load of the filler is relatively low, and the microorganism is in the self-oxidation stage, so the amount of sludge is small. In addition, the moisture content of the sludge produced by the biological contact oxidation pond is far below the moisture content of the sludge produced by the activated sludge tank. Therefore, the amount of sludge generated by the sewage after the sewage treatment equipment is small, and it is generally only necessary to discharge the mud once every 90 days.

5. The sewage treatment equipment adopts a low-noise rotary fan, which makes the noise of the equipment running less than 60 decibels, reducing the impact on the surrounding environment. Reduces noise, reduces energy consumption, and saves operating costs.

6. The sewage treatment equipment is equipped with a soil deodorization facility. The utility model utilizes the upper space of the reinforced concrete structure to improve the soil and the air pipe, and the malodorous component is dissolved in the water contained in the soil through the soil layer, and then adsorbed on the surface of the soil (or discharged into the sewer) and The chemical reaction is transferred to the soil, and the zui is finally decomposed by the microorganisms therein to achieve the purpose of deodorization. (This time is the direct access adjustment pool)

7. The sewage treatment equipment is equipped with automatic electrical control system and equipment damage alarm system, and the equipment runs reliably. Every day, someone must be cared for, need to be managed by someone, and usually have monthly or quarterly maintenance and care.

Equipment installation, commissioning and maintenance

Installation: This device consists of a set of pools. The pool body is buried underground. It is required that the excavation width of the surrounding area must be 500 to 600 mm or more larger than the plane dimension of the equipment .

According to the installation drawing, the steel structure pool body is hoisted by crane (also can be made on site). It must be carried out under the guidance of the technicians of our factory during the installation. The position and direction of the box cannot be misplaced, and then the factory is responsible for the pool. The connection between the pipes. The steel structure pool body is to be welded to the base embedded parts. In order to prevent groundwater from floating up the equipment. After the installation is completed, the equipment must be filled with water. The joints of the pipelines are not leaked, and the soil can be filled into the space around the equipment and leveled, and the ground is leveled. Connect the control panel of the electric control cabinet to the equipment, and connect the electric control cabinet to the power supply. Pay attention to the fan (distribution system) and the steering of the pump when wiring. After the equipment is installed, it must be ensured that there is no water on the rainy ground. The upper part of the steel structure tank body shall not be pressed with heavy objects. The equipment generally does not evacuate the internal sewage to prevent the groundwater from floating up.

Commissioning: The commissioning work is carried out by our factory (about 15 days). In order to speed up the commissioning, the bacteria can be put into the plant . In order to avoid the loss of bacteria, the water intake can be reduced and the fan (starting the gas system) can be started for aeration until the filler is applied. A layer of orange-yellow biofilm is produced, that is, the filler film is completed, and then the water intake is increased to the rated flow rate. After the filling film is completed, the microorganisms in the Class A biological pool are domesticated, that is, the aeration amount is gradually reduced, and the Class A biological pool is in an anoxic state, so that the microorganisms on the filler become facultative microorganisms. The microorganisms are then adapted to operate until the design requirements are met.

Equipment maintenance: The sewage treatment equipment should establish a regular maintenance system. The main vulnerable parts are valves and pumps. Regularly check the looseness of the screws in the valve and the pump, the tightness of the packing layer, the temperature of the bearing and the oil and oil quantity of the lubricating oil to ensure that the components are normal, and check the dosage and remaining amount of the disinfectant. If necessary, adjust the dosage and supplement the disinfectant. Valves and pumps must be serviced and repaired every 2000-3000 hours.

Embedding requirements and simple calculation

Equipment biological treatment technology

Aerobic biological treatment technology

According to the growth state of sludge, aerobic biological treatment technology can be divided into two major categories: activated sludge method and biofilm method. Among them, the activated sludge method has a high operating cost and has a sludge expansion problem, so it is not suitable for use in rural areas. In comparison, the biofilm process is easier to maintain and manage, and there is no sludge expansion problem, which can be considered when the land is limited. Biological contact oxidation

Biological contact oxidation is a biofilm treatment technology developed on the basis of biofilters through contact aeration. The biological contact oxidation tank is easy to operate and manage, and is more suitable for use in rural areas.

Aerobic biofilter

The aerobic biofilter generally uses gravel or plastic products as a filter material to uniformly spray the sewage onto the surface of the filter bed and form a biofilm on the surface of the filter material. After the sewage flows through the biofilm, the pollutants are absorbed and absorbed. Aerobic biofilters can be divided into three types: common biofilters, high-load biofilters, and tower biofilters. Among them, the tower type biofilter has high treatment efficiency, small floor space, and can save energy by natural ventilation, so it is suitable for treating rural domestic sewage. The tower biofilter is made of water from the top, and the sewage flows from top to bottom along the tower. Under natural oxygen supply, the aerobic microorganisms form a biofilm on the surface of the filter to remove the suspended, colloidal and dissolved pollution in the sewage. substance.

Anaerobic biological treatment technology

The anaerobic biological treatment technology does not require aeration and oxygenation, and has low sludge production. It is a low-cost, easy-to-manage sewage treatment technology that can meet the technical requirements of rural domestic sewage treatment.

Sewage purification biogas tank

The sewage purification biogas digesters are made up of a series of biogas digesters and anaerobic biofilters. They can be built by several households or single households with flexible layout.

Anaerobic biofilter

The structure of anaerobic biofilter is similar to that of aerobic biological contact oxidation tank. The difference lies in the sealing of the top of the pool. Its engineering investment and operating cost are low, and the requirements for maintenance personnel are not high. It has been applied in rural areas of China.

Compound anaerobic treatment

The composite anaerobic treatment technology is a combination of anaerobic activity method and anaerobic biofilm method. The composite anaerobic reactor consists of a light filter layer, a suspended anaerobic sludge bed, etc. The dual synergistic effect of anaerobic activated sludge and biofilm greatly improves the pollutant removal efficiency. In addition, by providing a special lightweight filter layer in the reactor, sludge loss is prevented, and the volume load and treatment effect of the reactor are improved.

Ecological treatment technology

Artificial wetland

The constructed wetland treatment system is derived from the simulation of natural wetlands, and mainly uses the synergy of plants, substrates and microorganisms in the natural ecosystem to achieve water purification. The main body of the constructed wetland consists of soil and fillers filled at a certain level, and plants are planted on the surface of the bed to form a unique ecosystem. The constructed wetland treatment system has good purification effect, simple process equipment, convenient maintenance and management, low operating cost, and significant ecological and environmental benefits. However, the inflow load requirement is relatively low and the floor space is large. Therefore, it is suitable for use away from urban sewage pipe network and with less capital. Small and medium-sized towns and rural areas with limited technical talents and land available.

Land treatment

Land treatment technology is a treatment method that utilizes a soil - plant - microbial complex ecosystem under artificial control to purify sewage through a series of physical, chemical and biological functions and to realize the recycling of nutrients in water and sewage. According to the flow velocity and flow trajectory of water flow movement, land treatment systems can be divided into four types: slow percolation system, rapid percolation system, surface drainage system and subsurface infiltration system (ie capillary land percolation treatment technology).

Stable pond

The stability pond is a sewage pond with artificial dikes and anti-seepage layers. The purification principle is similar to the self-purification mechanism of natural water bodies. Through the metabolic activities of microorganisms (bacteria, fungi, algae, protozoa, etc.) and the accompanying physical, chemical and physicochemical processes, the pollutants in the sewage are multi-stage converted, degraded and removed. . The stable pond has low construction investment, low operation and maintenance cost, and no sludge treatment, but the load is low, the land occupation is large, the climate is greatly affected, and the treatment effect is unstable. In order to further strengthen the treatment effect, many new types of ponds and combination ponds have been introduced at home and abroad. Such as high-efficiency algae ponds with continuous stirring devices, aquatic plant ponds that use aquatic vascular plants to improve treatment efficiency, multi-stage tandem ponds with multiple aerobic and anaerobic stabilization ponds, and advanced integrated ponds.

Materialized processing technology

The physical and chemical treatment methods of sewage mainly include: coagulation, air flotation, adsorption, ion exchange, electrodialysis, reverse osmosis and ultrafiltration. Among the various physical and chemical treatment technologies, only the coagulation technology is relatively in line with the rural requirements. The great advantage of Zui is that it can select the appropriate flocculant according to the nature of the pollutants in the sewage to ensure the efficient removal of pollutants. The coagulation technology has a good effect on the removal of suspended solids, metal ions, colloidal substances and inorganic phosphorus, but the removal ability of organic matter and nitrogen is relatively weak, and it is necessary to continuously add the medicament during the operation, so the running cost is high. In rural areas of China, coagulation technology is mainly used as a pretreatment measure or chemical phosphorus removal for ecological treatment systems.
