摘要
采用高碘酸钾分光光度法对总锰与可溶态锰进行了测定,研究了锰元素在净水处理过程的去除特性。结果表明:在各处理单元中,高锰酸钾预氧化可将原水中近60%的可溶态锰氧化成颗粒态;高密池对颗粒态锰的脱稳沉淀起主要作用,去除率高达85%以上;砂滤过程对可溶态锰的去除作用微乎其微。当原水进水总锰浓度在0.3mg/L时,出水总锰浓度仅为0.01mg/L,总去除率为90%。
In this work, the total manganese and dissolved manganese were determined by potassium periodate spec- trophotometry, and the removal characteristics of manganese in water purification process were studied. The results showed that pre--oxidation of potassium permanganate can oxidize nearly 60 %of the dissolved manganese in the raw water into particulate manganese. The high-density pool plays a major role in the destabilization of the particulate manganesewith a removal rate of over 85%. Sand filtration process on the removal of soluble manganese is minimal. When the total manganese concentration in raw water was 0.3 mg/L, the effluent concentration was just 0.01mg/ Land, the total removal rate was 90%.
