Landfill leachate efficient Fenton oxidation device

Abstract

A landfill leachate efficient Fenton oxidation device comprises a reaction tank, a motor is fixedly installed in the middle of the top side of the reaction tank, the lower end of a motor rotating shaft penetrates through the top wall of the reaction tank and is fixedly connected with the upper end of a telescopic shaft, and the lower end of the telescopic shaft is fixedly connected with the upperend of a screw of a reciprocating screw pair. The lower end of the screw of the reciprocating lead screw pair is rotationally connected with the middle of the top side of a piston plate through a bearing, the periphery of the piston plate is in sliding contact fit with the inner periphery of the reaction tank, and the bottom side of the piston plate is connected with the bottom of the reaction tank through a plurality of spring rods. Thelandfill leachate efficient Fenton oxidation device is simple in structure and ingenious in conception, sewage and an oxidizing agent are mixed more uniformlythrough the annular plates moving up and down, meanwhile, precipitates generated by reaction are collected between the two annular plates, the generated precipitates are automatically discharged through gravitational potential energy of the sewage, the cleaning difficulty of the reaction tank is reduced, market requirements can be met, and the reaction tank is suitable for popularization.

Description

technical field [0001] The invention belongs to the field of sewage treatment devices, in particular to a high-efficiency Fenton oxidation device for landfill leachate. Background technique [0002] The Fenton reaction is an inorganic chemical reaction. The process is that the mixed solution (oxidant) of hydrogen peroxide (H2O2) and ferrous ion Fe2+ oxidizes many known organic compounds such as carboxylic acids, alcohols, and esters into inorganic states. The reaction has a high ability to remove refractory organic pollutants, and is widely used in the treatment of printing and dyeing wastewater, oily wastewater, phenolic wastewater, coking wastewater, nitrobenzene-containing wastewater, and diphenylamine wastewater. However, in the actual sewage treatment process, because the mixed solution of the oxidant cannot be uniformly dispersed in the sewage, the sewage treatment efficiency is low, and the sediment produced at the same time gathers at the bottom of the reaction tank....

AI Technical Summary

Problems solved by technology

However, in the actual sewage treatment process, because the mixed solution of the oxidant cannot be uniformly dispersed in the sewage, the sewage treatment efficiency is low, and the sediment produced at the same time gathers at the bottom of the reaction tank. Due to the high concentration of the sediment, the bottom of the reaction tank is oxidized The reaction efficiency is reduced, and at the same time, the sediment is deposited at the bottom of the reaction tank, which is difficult to clean up, which leads to a reduction in the overall sewage treatment efficiency and cannot meet the actual needs. Therefore, we have invented a high-efficiency Fenton oxidation device for landfill leachate.
