加强管网水质管理,进一步提高供水水质

Strengthen water quality management of pipe network and improve water quality

介绍了上海加强管网水质管理情况,多年来水厂出厂水平均浊度0.08 NTU,管网水平均浊度保持0.11 NTU,仅增加0.03 NTU,采取管网补氯等措施降低出厂水余氯,使管网余氯更稳定平均,改善供水口感.开展管网综合指标检测,科学评价管网水质,确保管网水质.对上海二次供水改造提出设想和建议.

This paper introduces the water quality management of the reinforced pipe network of Shanghai,wherein over the past years,the increase of the average turbidity is only 0.03 NTU from that of finished water,0.08 NTU,to that of water in the pipe network,0.11 NTU,and wherein the residual chlorine in the finished water is reduced by chlorine supplement in the pipe network,etc.,to ensure stable and average residual chlorine therein to improve the taste of the supplied water.This paper also involves implementation of comprehensive index test for the pipe network to scientifically evaluate and ensure the water quality therein,as well as ideas and suggestions for the secondary water supply transformation in Shanghai.
