The waste water treatment equipment which assures the reuse of the water in finishing of trivalent chromate and the effluent treatment manner which assures the reuse of the water

摘要

Topic With plating treatment of the car Tanks part, with the manner which uses six value chromates, generally, on the galvanize, it is the structure canning with six value chrome mates, and the trivalent chrome mate. But, six value chrome mates, are times elution in connection with the temperature and humidity, the measure is urgent business, for example, there is a healthy fault and a degradation problem of the part for the human body. Constitution After the plating preprocessing and the trivalent chromate of the alkaline cleaning preprocessing and the galvanize preprocessing treating, with reuse manner of the water in finishing which finishes, alkaline cleaning preprocessing, distribution facilities to do the PH adjustment vessel, the cohesion vessel and the filtration equipment for clarifying, and the neutralization vessel etc, galvanize preprocessing, distribution facilities to do the PH adjustment vessel and the cohesion vessel and the precipitation device/the filtration equipment for clarifying, and the neutralization vessel, and the depot for return, the effluent treatment in after-treatment the trivalent chromate to correspond to guttation concentration, first process and katoritsujihuiruta of the trivalent chrome washing depot and the thickenerIt treats with second process of the RO device ion exchange tower.
