• 摘要：对铁、锰含量较高又存在有机微污染的原水进行深度处理的生产规模的净水厂(规模10m³/h),进行了运行效能的试验研究.该水厂由射流曝气→砂滤罐→臭氧接触氧化罐→生物活性炭滤罐→木鱼石滤罐→紫外线照射清水箱等处理单元组成.通过曝气充氧砂滤预处理,去除溶解性的二价铁60%以上,在剩余臭氧的量为0.4mg/L(相应的臭氧投量为:4mg/L)的条件下,经臭氧接触氧化和生物活性炭过滤,在HRT20min时,可去除铁锰高达100%,COD_Mn的去除率达90%左右.

• Abstract：The experimental studies were carried out in a full scale advanced drinking water treatment plant treating raw water with higher concentrations of iron, manganese and organic matter with a capacity of 10m³/h, which has the following flow chart: aeration with an ejector→Sand fillter→Ozone contact column→BAC filter→Muyushi/sand filter→Clean water storage tank with UV radiation →Water distribution system. It was indicated from the experiment that the divalent soluble iron(Fe²⁺) was removed in the aeration sand filtration stage by 60% or more; At the residual O.3 content of 0.4mg/L from ozone contact column, corresponding ozone dosage of 4mg/L, the residual iron, manganese and organic matter was removed effectively in the ozone column and biological activated carbon filter through various mechanisms with removal efficiencies for iron, manganese and COD_Mn of 100%, 100% and some 90% respectively.
