摘要
为了解淮安市区饮用水源水质状况,江苏省水环境监测中心淮宿分中心于1998年—2002年对淮安市区饮用水源地水质进行了监测,结果表明,二河闸水质达Ⅱ类水标准,五毒项目未检出;杨庄闸上游废黄河水质除1999年达Ⅲ类水标准外,其他年份水质均达Ⅱ类水标准,五毒项目未检出;京杭大运河淮安市区段及里运河水质较差,主要是氨氮超标严重,近5年水质基本都是劣于Ⅴ类水标准。指出,淮河污染问题还没有根本解决,沿淮上游积蓄的污水,时常以小流量下泄,并不时有所增大,经常发生水污染事故;淮阴第二抽水站抽水流量超过40m3/s时,京杭大运河及里运河污水对淮安市区北京路地面水厂、淮阴区地面水厂两取水口水质产生一定的影响。
From 1998 to 2002, the water quality of drinking water source in Huaian have been monitored. Water quality in Ehezha reached the Ⅱ water standard, five toxic items were not detected. Water quality in Feihuanghe River reached the Ⅱ water standard, except in 1999, five toxic items were not deteched. The water quality of Jinghangdayunhe (Huaian) was worse, can′t reach the Ⅴ water standard, NH3-N pollution was great. Because of pollution of the Huaihe River was still great, the polluted water from the Huaihe River often caused the water quality of drinking water source in Huaian.
