“预氧化+混凝沉淀”工艺处理景观水

景观水由于营养因素、环境因素及水力条件等多方面原因导致水体出现藻类暴发是一个复杂问题,采用单一的方法很难达到去除藻类的预期效果。本实验采用"预氧化+混凝沉淀"除藻,通过单因素和正交试验得出:当高锰酸钾投加量0.6 mg/L,氧化时间15 min,PAC投加量30 mg/L,沉淀30 min时,在低密度和高密度含藻水中藻类去除率可分别达到95.8%、97.2%,除藻效果良好。

Experimental Study of "Pre-oxidation & Coagulation" to Deal with Landscape Water

As the nutritional,environmental factors,water condition and many other reasons for the emergence of algae outbreak of landscape water is a complex problem,and using a single method to remove algae is very difficult to achieve the desired result.From the experiment of "pre-oxidation & coagulation"by a single factor and orthogonal,we concluded that when the dosage of potassium permanganate is 0.6 mg/L,and oxidation time is 15 min,and the dosage of PAC is 30 mg/L,and precipitation time is 30 min,and the rate ...
