Abstract

The invention provides an electric flocculation wastewater treatment system. The electric flocculation wastewater treatment system comprises an electric flocculation device and a reflux pipeline. Theelectric flocculation device comprises a conductive box body and an electrolytic piece, wherein a waste water treatment cavity is formed in the conductive box body and a water inlet and a water outletwhich are respectively communicated with the waste water treatment cavity are formed in the conductive box body, the electrolytic piece is arranged in the waste water treatment cavity. The reflux pipeline is connected between the water outlet and the water inlet. According to the technical scheme, the inner wall of the waste water treatment cavity can participate in electrolysis, the size neededby additionally arranging a cathode in the waste water treatment cavity is reduced, and the volume of the conductive box body is fully utilized. The waste water flowing out of the water outlet can befed into the conductive box body by the water inlet through the reflux pipeline for secondary electrolytic treatment or circulating electrolytic treatment, so that the treatment rate of heavy metal pollutants in the waste water can be improved, and the content of heavy metal pollutants in the waste water can be reduced as much as possible.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an electrocoagulation wastewater treatment system. Background technique [0002] At present, in the non-ferrous metal industry, one of the terminal wastewater treatment methods is the electrocoagulation process. The traditional electroflocculation process generally adopts an open electrolytic cell plus an iron plate to reverse the direction of electrolysis, and the electrolyzed wastewater enters the aeration tank for aeration. [0003] When the above-mentioned electrocoagulation process is used, the water flow rate is relatively slow, and the anode slime blockage between the plates is prone to occur; the electrolysis efficiency is limited by the area of ​​the iron plate, and the electrolysis efficiency is low. In addition, since the above-mentioned electrocoagulation process only performs one electrolytic treatment on the circulating wastewater entering the electrol...
