摘要
本文通过摸拟水厂混凝沉淀-过滤工艺,研究了ClO_2投量和投加点对水中Fe^(2+),Mn^(2+),S^(2-),CN-污染物的去除效果,并与液氯进行了对比,结果表明:随ClO_2投量增大,去除率也增加,且ClO_2效果优于液氯;后投ClO_2的去除效果好于中间投和预投ClO_2,且可省药.这为ClO_2在饮用水中的应用提供了科学依据.
Removal effect of C1O2 doses and dosing point on Fe2+, Mn2+, S2 and CN - etc. pollutants in water has been studied by using simulation technology of coagulation sedimentation-filtration in waterwork as compared with liquid chlorine. The results showed that effect of C1O2 better than liquid chlorine. This provide scientific basis for futher use of C1O2 in drinking water.
