摘要
从污水大规模回用的现实意义及技术可行性进行分析。在技术方面引入水源管道预氧化技术,以高锰酸钾作为预氧化剂,通过管道模拟试验,研究了高锰酸钾的投加量对有机污染物、浊度、NH3-N等的去除效应。结果表明,高锰酸钾作为管道预氧化剂,在除有机污染、除浊方面的效果优异。同时,确定最佳投药量在4~4.5 mg/L之间。
This paper carried on the feasibility analysis from the practical significance and the technical feasibility of the large-scale sewage reclamation. Then intruduced the water source pipeline preoxidized technology to the sewage regeneration pretreatment. The simulated pipeline experiment ,which used potassium permanganat to take the preoxidized medicinal preparation and taked the reused water by an ecological residence quarter as the experiment water, studied the remove efficiency about the organic pollution, the turbidity, NH3-N when changing the quantity of potassium permanganat. The result showed： potassium permanganate preoxidized has outstanding effect on eliminating the organic pollution and the turbidity and give a dose of medicine best the quantity between 4-4.5 mg/L.
