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...
