Analysis of Water Use in Smelters and Discussion on Measures of Water Saving and Emission Reduction
In order to understand the shortcomings of water intake in a smelter,reasonable water-saving and emission reduction measures were proposed,and water balance tests and analysis of production wastewater quality were conducted for the entire plant.The results show that:(1)the proportion of production pollution and wastewater in the factory is about 12％and 14％.(2)The water quality of various production wastewater in the factory is not suitable for direct reuse.It is advisable to adopt a terminal emission reduction method of pre membrane pretreatment+membrane treatment to reduce the amount of wastewater discharged.(3)By adding air-cooled water-saving equipment in the circulating water tank,rectifying pit overflow drainage,and adding membrane treatment+pre membrane pretreatment processes,approximately 39.5％of new water production can be saved.(4)Build a smart water management system consisting of a water balance diagram,subsystem monitoring diagram,3D pipeline diagram,smart water management report,and expert database system,while improving water metering facilities.Improve the water management level of the factory.
