Study on treatment technology improvement of acid wastewater from Guangzhou Copper Co. Ltd

This article provides some solutions to theimprovement of waste water treatment system in GuangzhouCopper Co. Ltd., subsidiary company of GISE, such asfocusing on the management to the waste water discharge,adding ceilings to store the sludge temporarily, andimproving the property of the fan to enhance the blendingability in the process of waste water discharge, etc. Theresults indicate that the system can meet the requirement ofenlarged production capacity, the disposing ability towastewater increases 70%, the quality of treatmentimproves, the wastewater system run more steadily, energyassumptions decrease (saving power $100, 000) and therecycle percentage of treated wastewater is more than 40%.
