Integrated MBBR sewage treatment equipment

The MBBR pool is filled with K3 filler. A mixed liquid return pump is provided in the MBBR tank, and the mixed liquid return pump is connected to a return pipe, and the return pipe is connected to the anoxic tank. The anaerobic pool and the anoxic pool are equipped with submerged water thrusters. The sludge in the secondary settling tank is extracted by the sludge discharge pump, and the sludge discharge pump is connected to the sludge discharge pipeline and the sludge return pipeline; the sludge discharge pipeline is connected to the sludge tank, and the sludge discharge pipeline is connected to the anaerobic tank.

Replacing fiber filler with K3 filler can increase the biomass, increase the operating load, and save the installation work of the filler while reducing the land occupation. The biofilm method can effectively reduce the amount of sludge, reduce the cost of sludge treatment, and improve the secondary sedimentation. pool processing effect.

Process introduction
1. The process of the new rural integrated domestic sewage treatment equipment is based on the MBBR process in the biofilm method, using A/O technology + biological filtration process, and the whole system integrates flow adjustment, solid-liquid separation, anoxic and aerobic , Biological filtration and other sections. There is no septic tank and regulating tank at the front end of the equipment, the sewage enters the equipment by itself, and the treated sewage is discharged by gravity.

2. Process flow: After urban domestic sewage enters the equipment, it replaces conventional septic tanks and regulating tanks. In an anoxic environment, the biofilm on the filler is used to degrade organic matter and remove large particles and suspended solids, improving the quality of domestic sewage. biodegradability;

3. Domestic sewage from villages and towns enters the aerobic tank, and the sewage is further treated by using the biofilm on the suspended filler under aeration conditions. The nitrification liquid at the bottom is gas-lifted and returned to the front-end anoxic tank for denitrification and denitrification treatment, and electrolysis at the same time; The treated water enters the biological filter tank for sedimentation and filtration to remove suspended solids in the sewage, and then enters the disinfection tank to complete the treatment of domestic sewage.

Equipment processing flow
1. Urban domestic sewage flows into solid-liquid separation to remove large particles;
2. After that, the sewage enters the aerobic pool for further treatment and denitrification and phosphorus removal;
3. Then enter the biological filter tank for sedimentation and filtration;
4. Then it will flow into the disinfection tank and be sterilized by chlorine tablets in the disinfection tank;
5. After treatment, the water quality is clear and meets the discharge standard.

Device effect
Through this integrated mode, the urban integrated domestic sewage treatment equipment combines the technical process of small-scale sewage treatment into an integrated device, which is powered by only one lift pump. Compared with traditional devices, it has a compact structure, It has the advantages of less investment, small footprint, simple construction, and low operating costs.

Urban integrated domestic sewage treatment equipment combines filtration, aerobic, sedimentation and other processes to form an integrated small-scale sewage treatment equipment; it can simultaneously realize multiple functions such as removal of organic pollutants, denitrification, precipitation, etc. After the processing equipment, follow-up sedimentation and related supporting equipment will be set up.

The urban integrated domestic sewage treatment equipment adopts the porous filter material contact oxidation process, which combines the non-powered fan technology to reduce the operating cost of the sewage treatment device. The porous filter material has a large specific surface area, good hydrophilicity, no clogging, high biological activity, fast film formation, good treatment effect, and decarburization and nitrogen removal capabilities.

In recent years, with the development of the economy in rural areas of our country, the transformation of residents' lifestyles and the improvement of living standards, the discharge of rural domestic sewage has continued to increase. Due to the scattered living of residents in rural areas, the lack of sewage collection pipe network systems and centralized treatment facilities, the formation of Point-like and disorderly pollution sources have seriously threatened the surrounding environment.

The traditional A2O process generally uses a blower for aeration, and the noise value of the fan as the aeration equipment is generally above 65dB, which will affect the daily life of the surrounding residents, and the use of a blower for aeration has low oxygen mass transfer efficiency and reduces water purification. efficiency.

MBBR small integrated rural domestic sewage treatment equipment is used to solve the traditional A2O process. Generally, blower aeration is used. The noise of the fan as aeration equipment will affect the daily life of the surrounding residents, and the blower is used for aeration, and the oxygen mass transfer efficiency Low, reducing the technical problem of water purification efficiency.

MBBR small-scale integrated rural domestic sewage treatment equipment includes anaerobic tank, anoxic tank, MBBR tank and secondary sedimentation tank connected in sequence; the aerobic tank is connected to the micro aerator installed outside the tank body. It also includes the equipment room, where the micro-aerator is installed, and the equipment room is also equipped with a power distribution cabinet and an ultraviolet sterilizer. The micro aerator consists of an atomizer connected through a gas-water mixture pipeline, and the atomizer is placed in the MBBR tank.
