Sewage treatment tank

Abstract

The invention discloses a sewage treatment tank. The tank comprises a tank body, a water pump and a water inlet pipe are mounted at the top of the tank body, the water pump is connected with the waterinlet pipe, a water inlet spray assembly and a medicine inlet assembly are mounted in the tank body, the water inlet spray assembly comprises a main water pipe and an auxiliary water pipe, the auxiliary water pipe is communicated with the main water pipe, the auxiliary water pipe is vertical to the main water pipe, a plurality of water outlet holes are formed in the auxiliary water pipe, spray pipes are installed on the water outlet holes, a medicine feeding assembly comprises a medicine feeding tube and a blower, the blower is fixed to the side surface of the tank body, one end of the medicine feeding tube extends into the tank body, the other end extends out of the tank body, one end extending outside the tank body is connected with the blower, a plurality of medicine outlets are formedin the medicine feeding tube extending into the tank body, and medicine blowing tubes are installed at each medicine outlet. The tank can make sewage fully contact with medicine powder, improve a purification effect and improve a purified water quality.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a sewage treatment tank. Background technique [0002] With the development of science and technology, environmental pollution is an increasingly serious problem, among which sewage treatment is the most important of many environmental problems. Sewage includes industrial sewage and domestic sewage. If the sewage cannot be completely purified and discharged directly, it will re-enter the earth's water cycle system, destroying the ecological environment, and the sewage will also enter the human body and affect human health. The existing sewage treatment tanks cannot filter the sewage, so that the sewage contains solid pollutants, which leads to the inability to purify the solid pollutants in time, making the sewage discharge not up to standard. In addition, the sewage cannot be recycled and purified, resulting in a low purification effect. [0003] The publication number is CN107324...

AI Technical Summary

Problems solved by technology

[0004] However, the contact area between the added medicinal powder and the sewage in the above-mentioned sewage treatment tank is still not large enough, the treatment effect is not very good, and the water quality after treatment is also relatively poor.
