对火电厂输煤系统冲洗水处理方案的研讨

Treatment Methods of Wash-Watcr for Coal-Carrying System of Thermal Power Plant

在对电厂输煤系统冲洗水处理方法的调查和对采集样本的试验、计算及分析的基础上，从排放废水须满足国家环保标准要求出发，对输煤系统冲洗水的处理和清除煤泥的方法进行了研讨．提出边进边排和先进后排两种沉淀处理方案及采用抓斗挖泥和刮板机配合污水泵排泥两种清淤方法，可供设计电厂的有关人员参考．

ased on the investigation of current methods,laboratory test data of collected samples and the national standard for waste water discharge,the treatment methods of wash- water and coalslack for coal-carrying systems of thermal power plants are studied.Two new practical methods are proposed which provide a basis for the design of similar systems.
