Intensive type rural domestic sewage treatment system

Abstract

The invention belongs to the technical field of sewage treatment and relates to an intensive type rural domestic sewage treatment system which comprises composition units including a grid, a regulating pond, a biochemical pond, precipitation and filtration integration equipment and the like. Sewage enters the regulating pond after passing through the grid firstly and then enters the biochemical pond; the biochemical pond can be rapidly started by adding a composite new bacterium by one time; in a contact process of the sewage and a biofilm, organic matters in water are adsorbed and decomposed through a special effect aerobic bacterium to produce CO2 and H2O; ammonia nitrogen is effectively and rapidly treated under the action of bacterial flora including an aerobic ammonifier to produce N2; and effluent of the biochemical pond enters a precipitation and filtration integration device, so that mud and water are separated from each other to enable the effluent to be further clarified, and the effluent subjected to treatment reaches the emission requirements and can be drained or reused. The intensive type rural domestic sewage treatment system is small in occupied area, little in investment, good in quality of the effluent and stable and convenient to run, can be rapidly started, can effectively treat rural domestic sewage and effectively protects a rural water resource environment.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an intensive rural domestic sewage treatment system. Background technique [0002] Due to poor economic conditions, lack of mature technology, low public awareness of environmental protection, and serious shortage of rural sewage treatment facilities, rural domestic sewage is discharged directly without treatment, causing pollution of rivers and ponds and deteriorating the surrounding water environment. Domestic sewage has become One of the main sources of pollution in rural areas today. [0003] Rural domestic sewage mainly includes washing, bathing, kitchen cooking, excrement and its flushing and other drainage. Due to the unbalanced rural economic development, the water quality and quantity of rural domestic sewage vary greatly from place to place. Generally speaking, rural domestic sewage has the characteristics of wide dispersion, multiple sources, rapi...

AI Technical Summary

Problems solved by technology

[0004] At present, my country has carried out some research on rural sewage treatment, but as far as rural domestic sewage treatment facilities are concerned, there are still the following problems: the cost of the treatment system used is high, the area is large, the energy consumption is high, it is difficult to manage, and the operation of the treatment system is difficult. Unstable, and the quality of the treated effluent is not satisfactory
