1, Overview of buried sewage treatment device;
The integrated domestic sewage treatment equipment adopts the world's advanced biological treatment process and integrates the removal of BOD5, COD and NH3-N. it is a more efficient sewage treatment equipment at present. It is widely used in the treatment of domestic sewage and similar industrial organic sewage in high-grade hotels, villas and residential quarters, replacing the septic tank with low removal rate and the effluent can not meet the national integrated discharge standard. The field application shows that the integrated buried sewage treatment equipment is a kind of domestic sewage treatment equipment with ideal treatment effect and convenient management.
2, Working principle of buried domestic sewage treatment equipment;
The removal of organic pollutants and ammonia nitrogen by integrated buried domestic sewage treatment equipment mainly depends on AO biological treatment process. Its working principle is in class A. due to the high concentration of organic matter in sewage, microorganisms are in anoxic state. At this time, microorganisms are facultative microorganisms. They convert organic nitrogen in sewage into NH3-N, and use organic carbon source as electron donor to convert NO2-N and NO3-N into N2. In addition, they also use part of organic carbon source and NH3-N to synthesize new cell substances. Therefore, A-class tank not only has a certain surface removal function, but also reduces the organic load of subsequent aerobic tank. It is conducive to nitrification, and depends on the high concentration of organic matter in the raw water to complete denitrification, and finally eliminate nitrogen eutrophication pollution. In grade o, the concentration of organic matter has been greatly reduced, but a certain amount of organic matter and higher NH3-N still exist in the sewage treatment equipment. In order to further oxidize and decompose the organic matter, and at the same time, nitrification can be carried out smoothly when carbonization is completed. An aerobic biological contact oxidation tank with low organic load was set up in grade o. There are mainly aerobic microorganisms and autoxidizing bacteria in the o-class tank. Aerobic microorganisms decompose organic matter into CO2 and H2O; Anaerobic bacteria use inorganic carbon produced by organic matter decomposition or CO2 in the air as nutrient source to transfer NO2-N and NO3 - no effluent from the tank to the tank of Grade A. It can provide electron acceptor for A-class tank and eliminate nitrogen pollution through denitrification.
3.2 process design description;
After the large granular and fibrous impurities are removed by the grid, the sewage flows into the regulating tank. The regulating tank is equipped with pre aeration and oxygen charging mixing, so that the sewage can be fully homogenized and evenly distributed, and the organic matter can be effectively degraded and the sludge deposition can be prevented. The sewage in the regulating tank is pumped into the sewage treatment system by sewage pump, which is composed of anaerobic tank, aerobic tank, sedimentation tank, buffer tank, filter, clean water tank, sludge tank, etc. The anaerobic tank is equipped with air agitation to control do ≤ 0.5mg/l. The anaerobic sewage flows into the aerobic tank. The aerobic tank is a biological treatment device based on biofilm process and activated sludge process. The rotary blower provides oxygen source. The organic matter in the device is adsorbed and degraded by microorganisms to purify the water quality. The aerobic tank adopts elastic packing, which has large specific surface area, and is not easy to make the biofilm form pellets. It also has the characteristics of fine bubbles, high oxygen utilization rate and uniform gas distribution. The sewage flows into the sedimentation tank by itself, and the precipitated water flows into the middle tank. Disinfectant is added to the tank for disinfection and sterilization. The effluent is lifted into the filter by the pump. The filter adopts mechanical filter. Under the appropriate grading conditions, it has the advantages of strong sewage interception capacity and good filtering effect. The effluent flows into the activated carbon filter, and after adsorption and filtration, it enters the reuse pool for reuse or flows into the municipal pipe network. The backwash water of the filter is discharged into the regulating pool for reprocessing.
The excess sludge in the sedimentation tank is airlifted to the sludge tank for aerobic digestion and stable treatment. The amount of sludge after aerobic digestion is very small, which is regularly filtered by the filter press, and the dry sludge is regularly transported out. The supernatant of sludge tank returns to the regulating tank for further treatment.
Note; The amount of sewage is less than 5M3 / h] the amount of sludge is very small. Generally, the environmental sanitation department is entrusted to transport the sewage by suction truck once a half year!

Various industrial sewage treatment similar to domestic sewage.
5, Characteristics of WSZ integrated buried domestic sewage treatment equipment;
1. The equipment can treat the comprehensive wastewater of living system and similar organic wastewater.
2. The two-stage biological contact oxidation treatment process of the equipment adopts the contact oxidation process, which is smaller than the activated sludge, has good adaptability to water quality, and the effluent quality is stable without sludge surge.
3. The equipment can be buried under the surface, and the surface can be used for greening or square, so the equipment does not occupy the surface area, does not need to build houses, and does not need heating and insulation.
4. The construction of the whole set of equipment is simple and easy to operate. All mechanical equipment are controlled automatically, and all devices and equipment are under the surface
5. Generally, the whole treatment equipment does not need to be managed by a special person, but only needs timely maintenance.
6. There is no need to compress the container. Air compressor and circulating pump and other equipment, thus greatly reducing the investment costs.
7. Low power, less maintenance and manual operation.
8. If the equipment is used in cold zone, the inspection hole can be raised to make the equipment buried under frozen soil.
9. The integrated buried domestic sewage treatment equipment is composed of two tanks, one is reinforced concrete structure with large buried depth, the other is steel structure with shallow buried depth. The steel structure pool adopts the first domestic interpenetrating network coating. It is a kind of interpenetrating polymer network formed by rubber network and plastic network. It can resist acid, alkali, salt, gasoline, kerosene and abrasion. Generally, the equipment can be painted with this coating for more than 15 years.
6, The foundation installation, use and maintenance of WSZ series buried domestic sewage treatment device;
1. Foundation: if the WSZ series equipment is placed above the floor, it only needs to prepare a concrete floor with the same appearance as the equipment as the foundation. The bearing capacity of the foundation must be greater than 4T / m2, and it is also required to be horizontal and smooth. If the equipment is buried under the floor, the foundation elevation must be less than or equal to the equipment elevation, and ensure that there is no water in the rain. The foundation is generally plain concrete (reinforcement depends on the local geological conditions).
2. Installation: according to the installation drawing, all boxes should be in place in turn. The position and direction of the box should not be misplaced. The distance between the boxes should be accurate and the pipes should be connected. Inject clean water into the equipment and check whether there is leakage in each pipe. If not, cover soil around the box until the equipment inspection hole and level the ground. Connect the control line of the electric control box to the water pump and the electric control box to the power supply. When wiring, pay attention to the direction of the fan and motor, which must be the same as the direction of the fan.
