不同工艺对水质安全处理副产物的效果分析研究

Effect Analysis of Different Processes on By-products of Water Quality Safety Treatment

采用气浮工艺与沉淀工艺对低温低浊度水质进行处理试验,结果表明,去除浊度效果均为1NTU时,气浮混凝工艺的助凝剂的使用量要比沉淀混凝工艺的少43%;在相同的助凝剂添加量下,气浮与沉淀工艺均可降低水中的高锰酸盐,气浮工艺的去除效果要好;对有机物(DOC)的去除,气浮混凝工艺要优于沉淀混凝工艺0.6%。

Air flotation and sedimentation processes were used to treat low temperature and low turbidity water.The results showed that when the turbidity removal effect was 1NTU,the use of coagulant aids in air flotation coagulation process was 43%less than that in precipitation coagulation process.With the same amount of coagulant aids,both air flotation and sedimentation processes can reduce permanganate in water,and the removal effect of air flotation process is better.For the removal of organic matter(DOC),the air flotation coagulation process is superior to the precipitation coagulation process by 0.6%.
