| Abstract: | Chemical coagulation,flocculation and ion exchange softening were used to deal with gas washing wastewater from wet electrostatic precipitator.A small and efficient wastewater treating and reusing systems were designed.SS,total hardness and total alkalinity in the wastewater were used as the main factors,when the inlet concentration was 350,365 and 315 mg/L,the outlet concentration could reach 7,75 and 70 mg/L after two main units treatment.The technology can meet the recycle standard,its operation cost is low and environmental efficiency is good. |
