Sewage treatment system

Abstract

The invention discloses a sewage treatment system which comprises a sedimentation tank body, a mixing chamber is arranged on one side of the sedimentation tank body, a rotating mechanism is arranged in the sedimentation tank body, a medicine storage box is arranged in the mixing chamber, a medicine control assembly is arranged between the medicine storage box and the mixing chamber, and a mixing assembly is arranged on the inner side of the mixing chamber. The amount of sewage entering the mixing chamber is judged by detecting the flow through the flow detector, the content of impurities in the sewage is judged by detecting the density of flowing sewage through the infrared detection head, the amount of the sewage introduced into the mixing chamber and the content of the impurities are intelligently detected, and then chemicals can be added according to detected data. Then the flow control valve in the medicine control assembly controls the medicine outflow amount of the medicine storage box after the flow detector and the infrared detection head detect the sewage, so that the use of the medicine can be intelligently controlled, and the waste caused by excessive use of the medicine and the poor flocculation effect of the sewage caused by too little use are avoided.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system. Background technique [0002] In sewage treatment, it is necessary to add drugs (generally flocculants, coagulants) for flocculation and sedimentation: the sewage is pumped into the sedimentation tank, mixed with drugs and sewage, and then left to settle. This process requires a lot of time to separate the sewage and drugs. Mixing is done to allow the drug to take full advantage, and it takes time for it to sit and settle. [0003] In the process of sewage treatment, it cannot be carried out simultaneously with other treatment processes. After flocculation and precipitation, the sediment produced; saving time will lead to drug flocculation time and reduce the flocculation effect. Therefore, how to change the flocculation process and speed up the flocculation time can be Further save time; in flocculation treatment, the existing method of remov...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a sewage treatment system, which has the advantages of fast mixing of flocculation agent and sewage, short flocculation process time, good flocculation effect, timely treatment of flocs, etc. Long, long time flocculation can achieve a good flocculation effect, a large amount of accumulation at the bottom of the sedimentation tank, affecting the decontamination effect
