Integrated sewage treatment equipment for heavy metal hazardous wastewater

Abstract

The invention discloses integrated sewage treatment equipment for heavy metal hazardous wastewater. The integrated sewage treatment equipment comprises a base, a primary filtering mechanism and a deep treatment mechanism, the base is used for mounting the preliminary filtering mechanism and the deep treatment mechanism; the primary filtering mechanism is used for filtering solid impurities in the hazardous wastewater; and the deep treatment mechanism is used for treating heavy metals in the hazardous wastewater. Through mutual cooperation of the base, the preliminary filtering mechanism and the deep treatment mechanism, the integrated sewage treatment equipment for the heavy metal hazardous sewage is realized, certain pressure can be applied to the sewage during filtering, so that the speed of the sewage penetrating through the filter screen is increased, and the sewage can be stirred while pressure is applied, furthermore, filter holes of the filter screen are effectively prevented from being blocked by filter residues, so that the filtering efficiency is improved, automatic water supply can be realized, the sewage treatment equipment is suitable for continuous operation, and the practicability of the sewage treatment equipment is improved.

Description

technical field [0001] The invention relates to the technical field of hazardous waste treatment, in particular to an integrated sewage treatment equipment for heavy metal hazardous waste and sewage. Background technique [0002] The main sources of heavy metal wastewater are mechanical processing, mining, iron and steel and non-ferrous metal smelting, etc. Heavy metals are toxic, and wastewater containing heavy metals must be treated before they can be discharged. When processing heavy metal wastewater, impurities in the wastewater must first be filtered. [0003] The sewage treatment equipment in the prior art only allows the sewage to realize the driving force through its own gravity, and then pass through the filter plate for filtration treatment, which leads to slow filtration efficiency and poor filtration effect during the filtration process, and it is extremely easy to Impurities are caused to block the filter screen, thereby reducing the filtration efficiency, and a...
