Adopt electric flocculation wastewater treatment device
Oct 12,2021
The prior art and the present invention has obvious advantages and beneficial effects compared specifically, seen from above technical solution, since the sewage treatment system comprising a pH adjustment tank, the reaction tank, pump, electrocoagulation waste water treatment apparatus, pH correction Pool, coagulation tank, solid-liquid separation device and product water pump ; sewage treatment is in accordance with the injection of heavy metal wastewater → pH adjustment → tubular electrochemical wastewater treatment → Al(OH)3 reactive coagulation → intermediate tank → solid-liquid separation → product water ; Especially the electro-flocculation wastewater treatment device is adopted. First, because the pipeline of the electro-flocculation wastewater treatment device is multi-stage, the upstream end of each pipeline is equipped with a detection valve and the downstream end is equipped with a dosing valve, so that the order of first detection and then dosing , If the detection concentration reaches the standard, there is no need to add medicine, if it reaches the standard, it will automatically add medicine, so that any pipe section can be added with medicine, and different medicines can be added in different pipe sections and different processes to meet the processing needs. Secondly, the anode and cathode electrodes exist in the form of pipes, and a leak-proof rubber tube is set on the outer jacket to provide a closed reaction space, the harmful gas generated will not escape, it is easy to control, the reaction is comprehensive, and the combination is convenient. Moreover, due to the sealed environment in each section of the pipeline, plus the pressure valve set at the water outlet, the gas can be pressurized, so that the gas solubility is higher and the treatment effect is better. Furthermore, the support frame in the pipeline can make the potion vortex, so that the potion can be better mixed, with higher solubility, and better processing effect ; in addition, because the components and specifications of each section of the pipeline can be freely combined, the equipment cost is low, and the structure is simple. , Easy to maintain. Finally, the pipelines can be connected in series to make the treatment effect better, or they can be connected in parallel to increase the treatment capacity, and the assembly methods are diversified to meet different sewage treatment needs.
