Compared with the prior art, the utility model has the following beneficial effects:

(1) In the domestic sewage treatment system in villages and towns of the present utility model, large-particle solid waste silt is carried out in the first filter tank for sedimentation, and the bottom of the first filter tank is funnel-shaped. The sludge is pumped out by the sludge pump. There is a clapboard in the filter tank, with a water inlet pipe on one side and an outlet pipe on the other side. The water inlet pipe discharges the sewage into the pool. Due to the function of the clapboard, the unsedimented sewage cannot directly flow to the bottom of the clapboard. The other side. After the sewage flows into the pool, it flows out of the first filter pool through the outlet pipe after sedimentation, so that the silt in the sewage is fully settled.

(2) In the second filter tank, the filter layer, the high-density filter layer and the sterilization and disinfection device can perform multi-channel filter layer filtration to enhance the purification effect. In the village and town domestic sewage treatment system of the utility model, the design of the sewage treatment equipment is reasonable, the bottom-up sewage treatment method is adopted, the purification effect is good, and the water quality of the treated sewage reaches the standard.
