KMnO_4与PAC联用预处理微污染源水的研究

Combined KMnO_4/PAC Process for Micropolluted Raw Water Pretreatment

为探寻微污染源水的预处理工艺,进行了高锰酸钾与活性炭联用去除运河水体中有机物、氨氮等污染物的试验研究。结果表明:在聚合硫酸铁、高锰酸钾、活性炭投加量分别为20、1.0、15 mg/L时,可将运河源水中的COD含量从113.6 mg/L降到9.66 mg/L,去除率达91.5%;氨氮含量从2.55 mg/L降到0.49 mg/L,去除率为80.8%,出水水质达到了Ⅱ类水源水标准。

Combined potassium permanganate and activated carbon technology was used to remove COD and ammonia nitrogen from micropolluted canal water. The research indicates that when the dosage of polyferric sulfate, potassium permanganate and activated carbon is 20 mg/L, 1.0 mg/L and 15 mg/L, respectively, the content of COD and ammonia nitrogen in canal water can be decreased from 113.6 mg/L to 9.66 mg/L and from 2.55 mg/L to 0.49 mg/L respectively, while the removal rates attain 91.5% and 80.8%. The treated water quality meets the classⅡ water source quality standard.
