The traditional sewage treatment process has prominent problems such as high pipeline investment, large land occupation, and long construction period, which seriously restrict the sewage treatment rate and COD reduction. In this situation, integrated sewage treatment equipment, as a simple and effective sewage treatment equipmentThe application is becoming increasingly widespread.

Integrated sewage treatment equipment utilizing membrane bioreactors for sewage treatment and reuseMBR buried sewage treatment equipmentGood effluent quality, low operating cost, strong impact resistance, low sludge volume, high degree of automation, small footprint, and easy integration. It can be used as a small-scale sewage treatment and reuse equipment, as well as a core treatment unit for larger sewage treatment plants, and has developed well in the sewage treatment industry.

Most of the existing integrated sewage treatment equipment only uses a single biochemical treatment process, which involves hanging elastic fillers in the pool. The elastic fillers have a large surface area, which is conducive to the attachment of microorganisms and increases the concentration of microorganisms in the pool, resulting in a good removal effect on organic matter.

Biological contact oxidation+filter is a good process combination to solve the above problems. The effluent can meet the discharge requirements, but it has disadvantages such as low equipment integration, large investment, and large footprint. Moreover, when the pollutants and suspended particles in the wastewater are small, traditional physical filtration methods are difficult to remove them, which affects the quality of recycled water and effluent.

MBR buried sewage treatment equipmentThe upper part of the anaerobic zone is equipped with a water inlet, and multiple parallel perforated water pipes are uniformly arranged longitudinally at the bottom. The water inlet is connected to the perforated water pipes through the water inlet pipe, and the bottom perforated pipe water distribution method is used to achieve uniform water distribution and stirring, allowing organic matter and microorganisms in the sewage to fully contact and improve treatment efficiency.

Both the bottom of the aerobic zone and MBR membrane zone are equipped with microporous aeration devices, which can maintain a certain amount of dissolved oxygen in the area. Aerobic microorganisms are used to oxidize organic matter into CO2 and H2O, reducing the organic content in the wastewater. Above the microporous aeration device at the bottom of the MBR membrane area, there is also a perforated aeration tube, which can be used to backwash the membrane element when it needs to be cleaned, and aerate it into the water through the perforated aeration tube for aeration cleaning. Above the perforated aeration tube in the MBR membrane area, MBR membrane components are installed to treat wastewater through the organic combination of membrane separation technology and biotechnology. The solid-liquid separation is efficiently carried out, with high removal rate of organic pollutants and stable effluent quality. Its separation effect is far better than traditional sedimentation tanks. The equipment has a compact structure, small volume, small footprint, and good effluent quality. One end of the main water collection pipe is connected to the MBR membrane module, and the other end is connected to the effluent self-priming pump through a third partition. By setting up a self-priming pump, the water is filtered through the MBR membrane module and extracted, reducing equipment energy consumption.
