Sewage emergency treatment system

Abstract

The invention discloses a sewage emergency treatment system comprising a pH value regulation device, a coagulation device, a flocculation device, an inclined pipe / inclined plate sedimentation tank and a sludge-water separation device which are connected with one another in sequence, wherein the sludge-water separation device comprises a swirler, a magnetic separator, a sludge concentration tank and a sludge dehydrator. The sewage emergency treatment system disclosed by the invention can be used for performing emergency treatment on sewage in sudden water pollution accidents and forming clean water and solid-state clods after treatment; the clean water does not contain suspended matters and metal substances, and can be recycled; the solid-state clods do not contain magnetic powder, and can be directly discharged without causing pollution to the environment; and therefore, the sewage emergency treatment system can be used for truly and effectively solving the governance in the sudden water pollution accidents fundamentally.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage emergency treatment system used in sudden water pollution accidents. Background technique [0002] With the rapid development of the economy, the phenomenon of large-scale and large-capacity water pollution caused by the excessive discharge of wastewater has caused serious problems such as drinking water difficulties and deterioration of the ecological environment, which has become a restrictive factor for social and economic development. To this end, the state and the government have strengthened the protection of the water environment in various fields. While strictly stipulating the sewage discharge standards and the discharge concentration standards of different pollutants, new sewage treatment plants of different sizes and types have been built, and new technologies and equipment have been introduced. Among them, magnetic separation technology can effective...

AI Technical Summary

Problems solved by technology

However, the sewage emergency treatment device in the prior art adopts simple coagulation and flocculation to precipitate the suspended solids and metal substances in the sewage, and adopts single-stage mud-magnetic separation, so the treatment effect of the sewage is poor, and the muddy water deposited after treatment is The magnetic powder separation is not complete, and the loss of magnetic powder is large. At the same time, the sludge in the muddy water cannot be effectively treated. Therefore, it cannot really effectively solve the treatment of sudden water pollution accidents.
