[0003] Therefore a rural sewage treatment reaction ditch, the public number for: CN209081665U, each household water collection after through the grid removes bulky paper, garbage and other articles, then enters the water channel. The bottom of the water channel is planted with aquatic plants, and the aquatic plants produce oxygen through photosynthesis to provide dissolved oxygen required for activated sludge reaction, and at the same time, the aquatic plants block the flow of activated sludge, forming a stable environment for activated sludge. The treatment effect of activated sludge is strengthened. In addition, the channel bottom is paved with 100mm thick goose egg gravel, which plays a role in filtering small suspended solids, increasing the concentration of activated sludge. Sewage forms a stable aerobic environment of activated sludge through the joint action of aquatic plants and goose egg gravel in the reaction ditch, and ammonia and digestion reaction occur in the sewage. After removing part of COD, BOD and SS, the sewage flows to the central water storage tank, which carries out denitrification reaction to remove ammonia nitrogen, total nitrogen and organic matter under anoxic environment. After two reactions and precipitation, sludge sinks to the bottom, and supernatant is discharged according to the liquid level rising condition.

[0004] But the grid is used to remove large garbage and sundries, but in actual operation, it is easy to be blocked by sundries, which causes the sewage to be unable to enter the water channel smoothly, and the grid needs to be cleaned irregularly, increasing the maintenance workload and cost.
