Problems solved by technology

[0003] During the electrolytic treatment of wastewater containing high concentrations of organic matter and heavy metals, a part of the precipitate will be precipitated. However, in the existing electrochemical wastewater treatment device, the precipitate after electrolysis cannot be directly separated from the water. After electrolysis, it needs to enter the next process for precipitation. separate

Abstract

The invention provides a wastewater treatment device and belongs to the field of wastewater treatment. The problems that a precipitate after electrolysis cannot be directly separated from water in anexisting electrochemical wastewater treatment device and a next procedure needs to be carried out for precipitation separation and the like are solved. The wastewater treatment device comprises a shell and an electrolysis device, the electrolysis device comprises cathode and anode pieces and a control device connected with the cathode and anode pieces; the cathode piece and the anode piece are positioned in the shell; a water inlet is formed in a bottom of the shell; the water inlet is provided with a valve, a top of the shell is provided with a filter membrane and an overflow port, the filtermembrane is used for filtering sediments, filtered water flows out of the overflow port, a bottom of the shell is provided with a drain outlet for discharging the sediments, the drain outlet is provided with a timing electromagnetic valve, and an aeration device is further arranged in the shell and used for aerating wastewater. The wastewater treatment device has the advantages that the precipitated and treated water is directly separated through the filter membrane and the like.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a wastewater treatment device. Background technique [0002] Industrial wastewater is one of the main causes of environmental pollution. Some industrial wastewater contains both high concentrations of organic matter and heavy metals. Electrolysis can be used to treat wastewater containing high concentrations of organic matter and heavy metals. Through electrode reactions, direct or indirect Oxidize and decompose various organic substances in water, and decompose macromolecules into small molecules; then participate in the electron flow movement in water to obtain electrons or lose electrons; finally, co-precipitate with iron salt or aluminum salt precipitated at the anode. The heavy metal ions in water first break the molecular chains of their complexes or chelates in water under the action of a certain voltage and current, and then participate in the replacement rea...
