The existing problems of rural sewage treatment field:
the water is so dispersed that hard to collect and process.
focus on construction but ignore operation; focus on plant construction but ignore pipeline plan.
The problems of rural sewage treatment that eager to be solved is how to guarantee the normal operation of water treatment equipment and stability of effluent water during the long-term operation period after completion.
Solution is using system-wide intelligent operation and maintenance based on small advanced integrated sewage treatment facilities, to ensure the long-term solution of rural sewage.
Integrated A2/O Equipment
A2/O is a kind of biochemical treatment process. Domestic sewage flows through anaerobic tank, anoxic tank, aerobic tank and secondary sediment tank for biochemical treatment. Phosphorus is released in the anaerobic tank; denitrification is carried out in the anoxic tank; carbon removal, nitrification and excessive phosphorus absorption are carried out in aerobic tank; water-sludge separation is carried out in the secondary sediment tank.
① Integrated equipment is convenient for small and medium-sized sewage collection and treatment; reduces civil construction work; well nitrogen and phosphorus removal performance;
② remote monitoring and operation is convenient for operation management
Scope of application:
① small and medium-sized, decentralized village and town sewage treatment points;
② suitable for project with scale of < 500 tons/day
Membrane Cube Intelligent Sewage Treatment System
It is an improved AO process, combined with membrane bioreactor technology (MBR), has good nitrogen and phosphorus removal performance; membrane separation is used instead of secondary sedimentation tank for solid-liquid separation. Bacteria, suspended solids and turbidity in the effluent are close to zero, with high stability. It meets the class A standard of Discharge Standard for Pollutants of Urban Sewage Treatment Plant (GB18918-2002).
① integrated equipment is convenient for small sewage collection and treatment;
② remote monitoring and operation is convenient for later operation management;
③ intelligent operation function is available to save energy consumption.
Scope of application:
① small-scale, decentralized village and town sewage treatment point;
② suitable for project with scale of 20-200 tons/day
