饮用水地表水水源95%受污染,自来水厂传统水处理工艺不能全部去除新的有机污染物和藻毒素、环境激素,管网污染,陈旧老化、渗漏率高,出厂水到用户自来水龙头,水质不合格率增加20%左右,二次供水污染,高层水箱、蓄水池不清洗消毒,水质安全得不到保证,桶装水、家用净水器管理不当致二次污染,管道分质直饮水尚未规范化管理。
面对这严峻形势,必须要加强对水质的检测,常规9项水质检测仪HD-B09的检测项目和量程:余氯:0.05-30mg/L,0.01mg/L;总氯:0.01-10mg/L,0.01mg/L;二氧化氯:0.01-20mg/L,0.01mg/L;浊度:0.5-300NTU,0.01NTU;色度:0-200度,0.01度;悬浮物:0.5-300mg/L,0.01mg/L;COD锰:0-25mg/L,0.01mg/L;PH:5.5-9.5, 0.01;氨氮:0.5-50mg/L,0.01 mg/L;
