Key innovations
The innovation of this product is that it combines MBBR with biological contact oxidation method, and uses a multi-stage AO system to strengthen denitrification and phosphorus removal to the first-level A standard. The unique carrier-flowing aerobic tank achieves simultaneous nitrification and denitrification and improves efficiency. Simultaneous treatment of sewage sludge reduces the amount of remaining sludge.
Potential economic benefits
Reduce sludge treatment and operating costs, meet high emission standards and avoid fines, flexibly adapt to decentralized scenarios, reduce initial investment, and improve comprehensive economic benefits.
Potential climate benefits
Reduce the amount of sludge and reduce carbon emissions from transportation and processing; strengthen denitrification and reduce N2O greenhouse gas emissions; and deploy decentralized systems to save energy consumption for centralized pipe networks.

Solution details

The company is committed to the R & D, manufacturing, sales, installation and operation of decentralized sewage treatment equipment. It is located in the most advanced decentralized sewage market in China. It has experienced full cruel competition baptism and has been deeply cultivated in subdivided fields for more than ten years. It is a service provider focusing on high-end decentralized sewage treatment equipment.


The LD-S series of integrated sewage treatment equipment is mainly aimed at small and medium-scale dispersed sewage and has deep requirements for denitrification and phosphorus removal. The equipment mainly adopts purification tanks, A/O technology, anoxic and aerobic biochemical treatment processes, and relies on the action of microorganisms to decompose organic pollutants in water. The multi-stage AO system has enhanced denitrification and denitrification performance, while the biological phosphorus removal performance is also improved. The effluent can meet the first-level A standard of the "Urban Sewage Treatment Plant Emission Standards".


Advantages:

1. Combination of MBBR traditional fluidized bed and traditional biological contact oxidation method;

2. Sewage sludge is treated simultaneously, with less remaining sludge;

3. The carrier flow aerobic tank has the characteristics of simultaneous nitrification and denitrification to enhance denitrification;

4. It can be adapted to local conditions and is suitable for domestic sewage treatment in various decentralized scenarios. Integrated equipment, flexible selection and assembly;
