Micro-power sewage treatment system

Abstract

The invention relates to a micro-power sewage treatment system. The system is structurally characterized in that a filter tank, an oil separation tank and a hydraulic grit chamber are sequentially communicated through a pipeline, the filter tank is communicated with a domestic sewage inlet pipe, a basket-type grid is arranged in the filter tank, the hydraulic grit chamber is communicated with a water distribution trough through a pipeline, the water distribution trough is communicated with a quick-separation biochemical tank, biological balls are filled in the quick-separation biochemical tank, the quick-separation biochemical tank is connected with an aeration fan through the pipeline, the quick-separation biochemical tank is communicated with a water collecting tank, the water collectingtank is communicated with a disinfection discharge tank through the pipeline, and the disinfection discharge tank is communicated with a disinfection device through the pipeline. The method has the advantages that a traditional biochemical treatment method is highlighted, so that a single biological treatment environment is converted into a variable biological treatment environment; the processing flow is simple, the integration is realized, the management is convenient, and the unmanned management is basically realized; an active sludge culture and domestication stage is not needed, a biofilm is quickly formed, the growth rate of microorganisms is fast, and the starting time is short; the impact load is large, the purification degree is high, and the operation is stable, the occupied area is small, the investment is low, the operation cost is low and the automation degree is high.

Description

technical field [0001] The invention relates to a micro-power sewage treatment system. Background technique [0002] Domestic sewage is the wastewater discharged from residents' daily life, mainly from residential buildings and public buildings. The pollutants contained in domestic sewage are mainly organic matter and a large number of pathogenic microorganisms. The organic matter present in domestic sewage is extremely unstable and easily rots to produce stench. Bacteria and pathogens reproduce in large numbers using organic matter in domestic sewage as nutrients, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge. [0003] The biochemical treatment of domestic sewage in the prior art generally has scattered processes, complex structure, high control requirements, and difficult start-up. Periodic cleaning or replacement of fillers, large amount of waste gas and sludge generated by the treatment process (secon...

[0003] The biochemical treatment of domestic sewage in the prior art generally has scattered processes, complex structure, high control requirements, and difficult start-up. Periodic cleaning or replacement of fillers, large amount of waste gas and sludge generated by the treatment process (secondary pollution), need for advanced treatment, large one-time investment and high operating costs
