摘　　要：针对引黄水库水体呈现冬季低温低浊,夏季高藻、高有机物的水体特征,以济南鹊山引黄水库原水为研究对象,开发了高锰酸钾预氧化/溶气气浮/炭砂滤池组合工艺,考察了工艺的运行参数及特性.试验结果表明,在KMnO4投加量0.3 mg/L、聚合氯化铝铁(PAFC)投加量3.0 mg/L(Al3+)、溶气压力0.3 MPa,回流比10%时,运行效果较优,浑浊度、颗粒数、TOC、叶绿素a、蓝绿藻平均去除率分别达到94.45%、99.34%、46.68%、66.64%、95.44%,嗅味由原水的4级降为出水的1.5级,二甲基异冰片(MIB)去除率92.47%,土臭素(GSM)在气浮池单元降至检出限以下.工艺对THMFP各组成部分CHCl3、CHBr3、CHClBr2、CHCl2Br去除率分别为42.86%、37.50%、30.30%、24.09%.试验结果表明,组合工艺对悬浮物、有机物、藻类、嗅味物质、消毒副产物前体物具有良好的去除效果.Aimed at the raw water quality characterizd by low temperature and low turbidity in winter, high algae and organic matter in summer,the combined process of potassium permanganate pre-oxidation/ dissolved air flotation/GAC-sand filter was developed to treat high algae water in Queshan reservoir. Test showed that the process could reach a better result when the dosage of potassium permanganate pre- oxidation was 0. 3 mg/L, the dosage of PAFC was 3 mg/L （ Al3 ＋ ） , the dissolved air pressure was 0.3 MPa and the recycle rate was 11%. The averaged removal efficiency of TOC, turbidity, particulate matter, chlorophyll a and blue-green algae by combination process were 46.68% , 94.45% , 99.34%66.64% and 95.44% , respectively. Odor level decreased with process flow, from raw water level 4 to effluent level 1.5. GSM treated by flotation unit was under the detection limit, and the removal efficiency of MIB reached 92.47%. The removal rate of each component of THMFP, including CHC13 , CHC12Br, CHClBr2 and CHBr3, were 42.86% , 24.09% , 30.30% and 37.50% , respectively. The combined process has a good ability to remove regular indices,algae,odor substances and precursors of disinfection byproducts.
