摘　　要：我国特别是北方寒冷地区的地表型水库原水普遍存在因腐殖质类有机物引起高色度的问题，采用液氯消毒的常规处理工艺很难满足人们对水质安全性的要求，为此，选择北方某自来水厂滤后水为处理对象，在中试条件下考察了砂滤／炭滤共同作用对腐殖质类有机物的去除效能。结果表明，砂滤／炭滤工艺可以有效去除原水中分子质量为1-5ku、容易生成消毒副产物的有机物；在试验进水浊度为0．10～0．27NTU、CODMn为1．10～1．47mg／L的条件下，出水浊度〈0．10NTU、CODMn降为0．43～0．79mg／L，对浊度和CODM。的平均去除率分别为59．07％和50．61％。Problems with high color caused by humic substances in surface reservoir raw water are common in China, especially in the northern cold region, and it is difficult for the conventional chlorine disinfection treatment process to meet requirements for water safety. Taking the filtered water in a north- em water treatment plant as a treatment object, the removal of humic substances by a sand/carbon filtra- tion process was investigated in a pilot test. The results showed that the sand/carbon filtration process could effectively remove organic matter with a molecular mass of 1 to 5 ku, which were likely to generate disinfection byproducts. When the influent turbidity and CODMn were 0. 10 to 0.27 NTU and 1. 10 to 1.47 mg/L respectively, the effluent turbidity was less than 0.10 NTU, CODMn was 0.43 to 0.79 mg/L, and the average removal rates were 59.07% and 50.61% respectively.
