Through the water balance and wastewater reuse analysis, the implementation of fine salt treatment of high and low waste water separation and transformation, in addition to iron and manganese filter backwash drainage and other measures to establish the whole plant water network on-line monitoring and statistical system, the company water consumption rate decend from 0.32kg/kWh to 0.16kg/kWh, the plant achieves all types of wastewater classification, quality of recycling, achieves the purposeofreducingproduction costsof water.
