【摘要】：腐殖酸和蛋白质作为水体中有机物的重要组成部分,是消毒副产物前体物的重要来源。为明晰腐殖酸、蛋白质在水库原水中的浓度变化及去除情况,于2015年5月—2016年4月对我国南方某市三座主要水库原水中腐殖酸、蛋白质浓度进行了一个水文年的监测,分析了腐殖酸、蛋白质的空间分布与变化趋势,同时研究了不同水处理工艺对原水中腐殖酸、蛋白质的去除情况。结果表明,A、B、C三座水库原水中腐殖酸平均浓度分别为2.04、2.06、2.54 mg/L;蛋白质平均浓度分别为0.12、0.11、0.10 mg/L,且7月份腐殖酸、蛋白质浓度均最高。常规工艺、BAC-UF工艺、O_3-BAC工艺对腐殖酸与蛋白质的总去除率分别为63.43%、68.10%、84.31%与53.45%、76.17%、81.96%。混凝沉淀单元对腐殖酸起主要去除作用,BAC单元对蛋白质去除效果较好,且在与臭氧联用时,BAC对腐殖酸的去除率可达55.17%,而超滤膜单元对腐殖酸、蛋白质均有良好的去除效果。
[Abstract]:Humic acid and protein, as an important part of organic matter in water, are important sources of disinfection by-product precursors. In order to clarify the change and removal of humic acid and protein in raw water of reservoir, the concentrations of humic acid and protein in raw water of three main reservoirs in southern China were monitored for a hydrological year from May 2015 to April 2016. The spatial distribution and changing trend of humic acid and protein were analyzed. At the same time, the removal of humic acid and protein from raw water by different water treatment processes was studied. The results showed that the average concentrations of humic acid in raw water of three reservoirs in A, B and C were 2.04, 2.06 and 2.54 mg/L;, respectively. The average concentrations of humic acid and protein were 0.12, 0.11 and 0.10 mg/L, respectively, and the concentrations of humic acid and protein were the highest in July. The total removal rates of humic acid and protein by conventional process, BAC-UF process and O_3-BAC process were 63.43%, 68.10%, 84.31% and 53.45%, 76.17% and 81.96%, respectively. Coagulation sedimentation unit plays a main role in the removal of humic acid. BAC unit has a good effect on protein removal. When combined with ozone, the removal rate of humic acid by BAC can reach 55.17%, while the ultrafiltration membrane unit has a good removal effect on humic acid and protein.
