由于目前饮用水地表水水源污染较严重,自来水厂传统水处理工艺又不能彻底去除有机污染物、藻毒素和环境激素,管网污染、陈旧老化、渗漏率高,导致出厂水→用户自来水龙头,水质不合格率增加20%左右。另外,高层水箱、蓄水池清洗消毒不规范,二次供水污染,水质安全得不到保证,因此,?
Due to the current serious pollution of drinking water surface water sources, the traditional water treatment plant can not completely remove the organic pollutants, algal toxins and environmental hormones, pipe network pollution, aging, high leakage rate, resulting in factory water tap → user faucet , The water quality failed to increase about 20%. In addition, high-level water tanks, reservoirs and non-standard cleaning and disinfection, secondary water pollution, water quality can not be guaranteed, therefore,?
