组合预处理工艺在处理阳澄湖微污染原水中的作用

The effect of combined pretreatment technology on treatment of micro polluted orignal water of Yang Cheng lake

根据自来水厂生产中微量污染原水的处理方法研究,发现可以通过一项组合式添加物预处理工艺,来达到出厂水水质的要求,即在取水头部按时投放添加剂高锰酸钾和粉末活性炭,经处理后,可有效地去除出厂水中的耗氧量、氨氮,降低水中的色度和臭味。

In research of the micro polluted orignal water,we find that by a technology of combined pretreatment,ie,add potassium permanganate and powder of active carbon on head of the getting water,so can efficiently eliminate the expend oxygen,ammonia nitrogen,decrease colour and foul smell in productive water.
