Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described;

As shown in Figure 1, a low-energy treatment system for domestic sewage includes: a regulating acidification area, a biochemical precipitation treatment area and an artificial filter area, and the above three are connected by pipelines to connect the regulating acidification area and the biochemical precipitation treatment area A pipeline aerator 4 is arranged on the pipeline between them, and the horizontal positions of the acidification zone, the biochemical precipitation treatment zone and the artificial filter zone are adjusted to be lowered by 10-15 cm in turn.

The water quality and quantity adjustment functional unit 11 and the hydrolysis acidification unit 12 are arranged in the regulation and acidification area; the water quality and quantity adjustment function unit 11 includes a water distribution tank 111 and a water distribution wall 112; the biochemical precipitation treatment area includes a biochemical unit 21 and a precipitation static unit 22; The pool area consists of a vegetation layer 321 , a filter material layer 322 , a supporting layer 323 and an anti-seepage layer 324 from top to bottom.

Sewage first enters the regulating acidification area, then enters the biochemical precipitation treatment area through the pipeline aerator 4 provided between the regulating acidification area and the biochemical precipitation treatment area, then enters the artificial filter area, and finally discharges up to the standard. After the sewage is treated in the regulating acidification zone, the water is lifted by the water pump 5, and the outlet pipe of the water pump is connected to the pipeline aerator 4 through PP, and the sewage enters the biochemical precipitation treatment zone through the pipeline aerator 4.

The water quality and quantity adjustment functional unit 11 and the hydrolysis acidification unit 12 are arranged in the acidification zone. The water quality and quantity adjustment functional unit 11 includes a water distribution tank 111 and a water distribution wall 112. The sewage enters the water quality and water quantity adjustment functional unit 11 through the water inlet pipe 113, and passes through the deflector. 114 guides the flow through the water distribution wall 112 to complete the adjustment of the balanced water quality and quantity, and then guides the flow into the hydrolysis and acidification functional unit 12 by the guide plate 114. The flow wall 122, the sewage on the upper layer enters the water storage tank 125 through the outlet 123, and the sewage on the lower layer flows back through the return pipe 124, and the water pump 5 in the water storage tank 125 lifts the water, so that the sewage enters the biochemical precipitation treatment area through the pipeline aerator 4; In the acidification unit 12, the organic macromolecules in the sewage are degraded into organic small molecules, the organic volume load in the sewage is reduced, some pollutants are separated from the water and degraded preliminarily, realizing the phase transfer of some pollutants.

The biochemical precipitation treatment area includes a biochemical unit 21 and a sedimentation unit 22; the initially degraded sewage enters the biochemical unit 21, and the sewage fully contacts with the biofilm 211 in the biochemical unit 21. The ecological base further degrades the sewage through the synergy of biology, physics and chemistry. After the degraded sewage enters the settling unit 22, the sewage in the lower layer flows back through the return pipe 221, and the sewage in the upper layer enters the artificial filter area through the pipe.
