Biochemical sewage separation, stirring, filtration and purification treatment system

Abstract

The invention discloses a biochemical sewage separation, stirring, filtration and purification treatment system. The system comprises a support frame, wherein the top of the support frame is providedwith a coagulation device. Through a flocculant injection device, a flocculant can be automatically injected into sewage without manual operation of workers, so that the workload of the workers is reduced; meanwhile, the flocculant injection device can control the injection amount of the flocculant according to the purification degree of the sewage, so that it is ensured that the injection amountof the flocculant is matched with the amount of the sewage, the situation of excessive or insufficient flocculant addition is avoided, the consumption of the flocculant is reduced, and the sewage treatment effect is improved. Through a water discharging device, the sewage which reaches the standard can be discharged immediately, and therefore the defect of manually controlling the coagulation timeis effectively avoided, so that the sewage treatment effect and the sewage treatment efficiency are improved. Through a sludge-sewage separation device, the work of separating sewage from sludge andthe coagulation process are synchronously carried out, so that the sewage treatment time is shortened, and the sewage treatment efficiency is improved.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, and more specifically relates to a system for separating, stirring, filtering, and purifying biochemical sewage. Background technique [0002] Sewage refers to the general term for water discharged during residential activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other useless water such as primary rainwater flowing into drainage pipes and channels. Sewage treatment refers to the process of discharging sewage into a certain water body or The process of purifying water according to the water quality requirements for reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the ordinary People's daily life is classified according to the source of sewage. Sewage tr...

AI Technical Summary

Problems solved by technology

[0005] The coagulation and sedimentation tank in the existing sewage treatment system in the prior art is composed of a reservoir, agitator, water pipeline, control valve, etc. When in use, both the injection of sewage and the injection of flocculant require Manual operation by workers makes it difficult to control the ratio of sewage to flocculant. Adding too much flocculant will cause waste of flocculant, adding too little flocculant will affect the purification effect of sewage, and the coagulation time is controlled by workers. If the time is too short, the sewage treatment effect will be deteriorated. If the coagulation time is too long, the sewage treatment efficiency will be reduced. At the same time, the sludge generated during the coagulation process is separated from the mud and water by standing, and the separation speed is slow, which further reduces the sewage The problem of treatment efficiency, the purpose of the present invention is to provide a biochemical sewage separation, stirring, filtration and purification treatment system, which can well solve the problems raised in the background technology
