高锰酸钾-沸石联用预处理微污染运河水的研究

针对运河常州段微污染水源,进行了高锰酸钾-沸石联用预处理运河水中的COD和氨氮试验研究。通过试验得到:在投加聚合硫酸铁20 mg/L,高锰酸钾1.0 mg/L,沸石300 mg/L时,运河水中的COD的含量从113.6 mg/L下降到11.4 mg/L;氨氮含量从2.55 mg/L下降到0.43 mg/L。去除率分别达到90.0%和83.1%,使有机物和氨氮的含量达到Ⅱ类水源水质标准。

Potassium Permanganate-Zeolite Process for Purification of Micro-Polluted Source Water of Grand Canal

Potassium permanganate-zeolite combined process was used to remove organic and ammonia nitrogen from micro-polluted canal water.The results indicated that the content of organic in the canal water decreased from 113.6 to 11.4mg/L,the content of ammonia nitrogen decreased from 2.55 to 0.43mg/L,and the total removal rates were 90.0% and 83.1%,respectively,at the dosage of polymer ferric sulfate 20mg/L,potassium permanganate 1.0mg/L and zeolite 300mg/L.
