Study On The Recycling Technologies Of Copper Nickel Smelting Wastewater

According to a well-known domestic nickel copper smelting enterprises discharge of industrial wastewater,rough process control,end governance pressure,low utilization rate of water,and the environmental risk of water pollution is big.the comprehensive research and combed the enterprise source of industrial waste water discharge and water treatment facilities and the problems existing in the water reuse pattern,the operation principle and method of system engineering,by means of quantitative and qualitative methods,guided by the circular economy idea,to waste reduction and recycling as the core,combined with the enterprise actual situation,R&D a set of source reduction,process control,end governance,and gray water recycle system of wastewater reuse technology after treatment,sach as thermoelectric cooling tower water overflow reuse for dressing,nickel carbonate used in acid waste gas treatment,recycle water reuse way to development,and acidic wastewater standard management etc.make the enterprise wastewater discharge are greatly reduced,the water in the reuse 100%,make a wastewater production,disposal and reuse balance,implements the biggest industrial wastewater resource utilization and minimize emissions and new each year for the enterprise to reduce water use and wastewater treatment costs 108.12 million yuan,in solving the problem of water pollution environment at the same time,effectively solve the regional water resources shortage,economic benefit,social benefit and environmental benefit is remarkable,working for the industrial wastewater pollution control provides advanced ideas and success technology model.
