常见污水处理工艺,你都知道吗?

1物理法:

1.沉淀法:主要去除废水中无机颗粒及SS

2.过滤法:主要去除废水中SS和油类物质等

3.隔油:去除可浮油和分散油

4.气浮法:油水分离、有用物质的回收及相对密度接近于1(水的密度近似1)的悬浮固体

5.离心分离:微小SS的去除

6.磁力分离:去除沉淀法难以去除的SS和胶体等


2化学法:


1.混凝沉淀法:去除胶体及细微SS

2.中和法:酸碱废水的处理

3.氧化还原法:有毒物质、难生物降解物质的去除

4.化学沉淀法:重金属离子、硫离子、硫酸根离子、磷酸根、铵根等的去除


3物理化学法:


1.吸附法:少量重金属离子、难生物降解有机物、脱色除臭等

2.离子交换法:回收贵重金属,放射性废水、有机废水等

3.萃取法:难生物降解有机物、重金属离子等

一级处理,主要去除污水中呈悬浮状态的固体污染物质,物理处理法大部分只能完成一级处理的要求。经过一级处理的污水,BOD一般可去除30%左右,达不到排放标准。一级处理属于二级处理的预处理。

二级处理,主要去除污水中呈胶体和溶解状态的有机污染物质(BOD,COD物质),去除率可达90%以上,使有机污染物达到排放标准。

三级处理,进一步处理难降解的有机物、氮和磷等能够导致水体富营养化的可溶性无机物等。主要方法有生物脱氮除磷法,混凝沉淀法,砂滤法,活性炭吸附法,离子交换法和电渗分析法等。
