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...

Examples

Embodiment Construction

[0022] In order to make the object, technical scheme and advantages of the present invention clearer, the following combination figure 1 And embodiment, the present invention is described in further detail. The specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] refer to figure 1 It can be seen that an intensive rural domestic sewage treatment system includes a grid 1, a regulating tank 2, a biochemical tank 3, and an integrated sedimentation and filtration device 4 that are sequentially arranged and connected, and includes the following steps:

[0024] (1) Rural domestic sewage undergoes preliminary precipitation and nitrification in septic tanks, and then enters the sewage treatment system. First, it passes through the grid 1 to intercept larger suspended solids or floating solids, and the filtered grid slag is transported out regularly;

[0025] (2) Then the sewage enters the regulating tank 2 to...
