Sewage treatment device

Abstract

The invention discloses a sewage treatment device. The sewage treatment device comprises a sewage tank, a drainage hole is formed in the tank bottom of the sewage tank, the sewage treatment device further comprises a rotating device, wherein the rotating device comprises motors mounted outside the sewage tank, rotating shafts in transmission connection with the power output ends of the motors and extending into the bottom of the sewage tank, and a plurality of rotating plates which are arranged on the rotating shafts and arranged at intervals, when wastewater in the sewage tank is discharged, firstly, the rotating shafts are driven to rotate via the motors so as to drive the rotating plates to rotate, and then the rotating plates which are rotating stir water in the sewage tank, so that solid waste deposited at the tank bottom or the tank wall is activated along with stirred water, and then the drainage hole in the bottom of the sewage tank is opened; therefore, sediments flow out together with wastewater from the drainage hole, thereby being capable of effectively discharging the sediments to the outside of a culture pond to avoid accumulation and attachment of the sediments for a long time so as to improve the treatment efficiency of sewage.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a sewage treatment system. Background technique [0002] Carrying out clean production and saving water is a measure required by sustainable development. Seeking a stable benefit and environment-friendly sewage treatment device has very urgent practical significance for environment-friendly and sustainable development. The circulating sewage treatment system is considered to be one of the most developing devices at present because of its advantages of water saving, land saving and environmental friendliness. In the prior art, the bottom of the sewage tank of the sewage treatment device is prone to deposit a large amount of solid waste due to long-term accumulation, and even a large amount of solid waste is easy to adhere to the surrounding walls of the sewage pool, although many manufacturers have opened drainage holes at the bottom of the sewage pool , but the solid sed...

Problems solved by technology

In the prior art, the bottom of the sewage tank of the sewage treatment device is easy to deposit a large amount of solid waste due to long-term accumulation, and even a large amount of solid waste is easy to adhere to the surrounding walls of the sewage pool, although many manufacturers have opened drainage holes at the bottom of the sewage pool , but the solid sediment is still difficult to flow out of the sewage tank with the discharged water due to adhesion. Over time, it is easy to cause the sewage tank to be occupied by a large amount of sediment, which affects the efficiency of sewage treatment
