Research on Comprehensive Utilization Plan of Coal Mine Wastewater
There are problems in the production and operation of wastewater purification water treatment in a coal mine in Shanxi Province,such as substandard water quality and insufficient water quantity to meet usage needs.In response to this situation,after technical research and optimization of previous wastewater processes,a PEC(photoelectrocatalysis)+quartz sand filter+low-pressure reverse osmosis+CDI(capacitive deionization)process has been proposed,which can produce 2 000 m3 of water per day.The water production and quality meet the requirements of the coal mine's domestic water and emulsion water use,and have good safety and economic benefits.
