Electric flocculation unit, electric flocculation device and heavy metal wastewater treatment system

Abstract

The invention belongs to the field of heavy metal wastewater treatment and provides an electric flocculation unit, an electric flocculation device and a heavy metal wastewater treatment system. The electric flocculation unit comprises a shell, an anode bar, a cathode tube, iron carbon ball filler, a rotary type scraper device, an ultraviolet lamp, an aerating device, a power module and a liquid conveying mechanism, wherein the cathode tube is vertically arranged in the shell, the anode rod is vertically arranged in the cathode tube, the rotary type scraper device and the ultraviolet lamp are arranged in the cathode tube, the rotary type scraper device is movably connected with the shell through a bearing, the shell is detachably connected with the cathode tube and the anode bar, an insulating plate where a diffluence hole is formed is detachably connected to the cathode tube, and the iron carbon ball filler is stacked on the insulating plate. The electric flocculation device disclosed by the invention comprises a plurality of electric flocculation units, supports and liquid storage tanks, wherein the electric flocculation units, the supports and the liquid storage tanks are communicated through pipelines to be in parallel connection or serial connection. The heavy metal wastewater treatment system comprises the electric flocculation device, an air floating device and an ion exchange device, wherein are sequentially connected with each other. The heavy metal wastewater treatment system disclosed by the invention has a good heavy metal wastewater treatment effect and convenience in disassembling and cleaning.

Description

technical field [0001] The invention belongs to the technical field of heavy metal wastewater treatment containing organic wastewater, and in particular relates to an electroflocculation unit, an electroflocculation device and a heavy metal wastewater treatment system. Background technique [0002] With the acceleration of urbanization in our country, the problems caused by heavy metal pollution have become increasingly prominent environmental problems and people's life safety problems. Heavy metal pollution will not only cause acute poisoning and subacute poisoning to the human body, but also carcinogenic, teratogenic, and mutagenic, and the harm shown is long-term. [0003] In 2011, the State Council approved the "Twelfth Five-Year Plan for Comprehensive Prevention and Control of Heavy Metal Pollution". Reduce by 15%. By 2015, the discharge of heavy metal pollution in key areas and key areas will be reduced by 15% compared with 2007, and the discharge of key heavy metal p...
