Efficient pretreatment equipment for high-concentration chemical wastewater

Abstract

The invention discloses efficient pretreatment equipment for high-concentration chemical wastewater. The equipment comprises a bottom plate, a plunger water pump is fixed to the top face of the bottomplate through bolts, the outlet of the plunger water pump fixedly communicates with a discharge pipe, supporting legs are fixedly connected to the end portions of the top face of the bottom plate, and a pretreatment equipment body is arranged at the top ends of the supporting legs; the sludge is drained through a sludge receiving device, so the moisture content in sludge is reduced, the sewage dripping in the sludge transfer process is reduced, and environmental protection is facilitated; through cooperation of the sludge receiving device and a rotating arm, the drained sludge is automatically poured out, and manual cleaning is not needed, so time and labor are saved; and sewage in a liquid accumulation barrel and an inner container box is automatically selected to be drained through a drainage control device, and manual control is not needed, so operation is easy and convenient, and the practicability of the efficient pretreatment equipment for the high-concentration chemical wastewater is improved.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, more specifically, to high-efficiency pretreatment equipment for high-concentration chemical wastewater. Background technique [0002] High-concentration chemical wastewater has high pollutant concentration, high toxicity, and poor biodegradability, so it cannot be directly treated by traditional biological processes. For chemical wastewater with high concentration and refractory degradation, pretreatment methods are often very effective, which can reduce Or remove some toxic and harmful organic substances to improve their biodegradability and create conditions for subsequent treatment. At the same time, in order to achieve better treatment effects, two or more pretreatment technologies are often used in combination in practice. To achieve good benefits, the purpose of pretreatment is to remove or degrade harmful organic substances, improve its biological treatment, and at the same time ...

AI Technical Summary

Problems solved by technology

[0003] The existing high-efficiency pretreatment equipment for high-concentration chemical wastewater uses the cooperation of the filter screen and the granular material layer to filter the high-concentration chemical wastewater to achieve the purpose of intercepting solid impurities in the sewage. However, in the actual use process, the top surface of the filter screen A lot of solid impurities are often accumulated on the screen, and these solid impurities accumulate together to form sludge, which will block the mesh holes on the filter screen, resulting in a decrease in water treatment efficiency, and the sludge cannot be discharged automatically, requiring workers to carry out sludge treatment. Cleaning is time-consuming and laborious, so it is urgent to design a high-efficiency pretreatment equipment for high-concentration chemical wastewater
