Project Case of Emergency Nitrate Removal in XC WTP
The raw water of XC water treatment plant(WTP)in QX City has seasonal nitrate content exceeding the standard.To protect the drinking water safety of residents and reduce the nitrate content in the water body,it is adopted the process transformation program of"selective nitrate ion exchange compsite advanced treatment+reclaimed wastewater safe disposal and reuse system"in the WTP,and the nitrate concentration of the effluent water is kept below 3 mg/L.The system has a certain degree of removal of ammonia and nitrogen,organic matter,and turbidity in water,and has no effect on total dissolved solids(TDS),pH,and other water quality indices.And the treated water fully meets all the requirements of China's current hygiene standards for drinking water.A transformation project per ton of water treatment cost is about 0.4 yuan.The project is both high efficient and economical.It can provide a reference for the transformation of the same type of WTP.
