复合酵素和麦饭石在黑臭水体处理中的应用研究

Application of Compound Enzyme and Maifan Stone in Treatment of Dark and Odorous Water Body

本文重点介绍用复合酵素和改性麦饭石对黑臭水体进行修复试验的方法以及原理,利用复合酵素和改性麦饭石的协同作用,对黑臭水体中的NH_3、COD、BOD5、S^(2-)及Fe、Mn等重金属有较高的去除率。试验表明,当水体中复合酶的浓度达5.5 mg/L、改性麦饭石的浓度达到0.4 mg/L时,COD、BOD_5、NH_3、S^(2-)及Fe、Mn降低率分别为84.7%、84.8%、65.3%、95.5%、63.8%、66.3%,处理效果最佳。

This paper mainly introduces the method and principle of repairing black and smelly water with compound enzyme and modified rice stone. Through the synergistic effect of compound enzyme and modified rice stone, it has high removal rate of heavy metals such as NH3, COD, BOD5, S^2- and Fe and Mn in the black and smelly water body. The results showed that the reduction rates of COD, BOD5, NH3, S^2-, Fe and Mn were 84.7%, 84.8%, 65.3%, 95.5%, 63.8% and 66.3% respectively when the concentration of the compound enzyme was 5.5 mg/L and the concentration of modified rice stone reached 0.4 mg/L, and the treatment effect was the best.
