摘要 淮安自来水有限公司北京路水厂是在上世纪70年代建成的日供水量9万m3的水厂,水厂水源取自洪泽湖下游二河水,主要工艺为混凝沉淀+砂滤+消毒;根据水源水质、现有工艺以及水厂的占地情况,通过对各种深度处理工艺的试验和研究,淮安自来水有限公司于2011年2月确定选择占地面积小、出水水质优、操作维护方便的磁性离子交换树脂(MIEX)深度处理工艺用于该水厂的深度处理;水厂从2011年8月开工进行深度处理工程改造,于2012年6月25日调试通水成功,MIEX工艺的设计通水倍数为800BVTR;改造后的水厂处理工艺为:MIEX+混凝沉淀+砂滤+消毒;MIEX系统运行后大大提高了水厂的产水水质、降低了后续工艺的加药量并降低了供水中的消毒副产物;改造后该水厂CODMn去除率为60%,消毒副产物降低80%;使该厂出厂水满足国家新的《生活饮用水卫生标准》(GB5749-2006)的要求。
