Sewage processing equipment settling pond circulating sludge stirring structure

Abstract

The invention discloses a sewage processing equipment settling pond circulating sludge stirring structure, and belongs to the technical field of sewage processing. The sewage processing equipment settling pond circulating sludge stirring structure comprises a settling pond, a sewage pump, a lifting pipe and an annular blow-off pipe, a mud bucket is arranged at the bottom of the settling pond, thesewage pump is fixed at the bottom of the mud bucket, and the discharge end of the sewage pump is connected with the upward lifting pipe; a plurality of drainage holes are evenly formed in the annularblow-off pipe, the annular blow-off pipe is horizontally arranged at the position 30-50 cm above the mud bucket, a water inlet is formed in the lower surface of the annular blow-off pipe, and the annular blow-off pipe is connected with the top of the lifting pipe through the water inlet. Sludge at the bottom of the settling pond is pumped to the upper part of the mud bucket by the sewage pump; water with sludge is uniformly discharged and settled again through the drainage holes in the annular sewage discharging pipe, the sludge at the bottom of the settling pond is circularly stirred throughthe structure, air generated in the sludge is discharged, the sludge is prevented from floating upwards, only the sludge at the bottom of the settling pond is stirred in the stirring mode, and the suspended matter concentration of clarified liquid above the settling pond cannot be increased.

Description

technical field [0001] The invention relates to a structure for circulating and stirring sludge in a sedimentation tank of sewage treatment equipment, belonging to the technical field of sewage treatment. Background technique [0002] In recent years, with the rapid development of rural areas, rural environmental issues have received more and more attention, among which water pollution is one of the most important issues. There are currently more than 600,000 administrative villages in my country, and only 6.7% of them treat domestic sewage. Due to the wide distribution of rural sewage, difficulty in centralized treatment, and large changes in water quality and quantity, these problems have become the focus of my country's rural water environment governance. Restricting factors seriously affect the quality of the rural environment. In view of the random discharge of sewage in rural areas and the basic situation of water pollution, we should promote the construction of new co...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a sewage treatment equipment sedimentation tank circulation stirring sludge structure, which solves the problem that the sludge in the current sedimentation tank is easy to accumulate at the bottom to form a dead zone and consume more dissolved oxygen to cause sludge floating problem
