摘要
研究了混凝、超滤、臭氧、活性炭等工艺对高藻期太湖水的处理效果,结果表明:当进水浊度波动较大时,混凝超滤最终出水浊度平均为0.02 NTU,大大低于《生活饮用水卫生标准》(GB5749-2006)的上限值3。混凝-超滤-臭氧-活性炭组合工艺对CODMn的平均去除率达到90.5%,原水水质降至平均值1.16 mg/L,达到了《生活饮用水卫生标准》(GB5749-2006)的要求。该组合工艺对UV254的总去除率平均值为94.3%,去除效果明显,最终出水嗅阈值平均值为2,低于管道直饮水水质标准(Q/ZLS001-1998)的上限标准3。组合工艺出水未检测到藻类,保证了水质的生物稳定性。该组合工艺能充分发挥各自的作用,提高处理效果,保障饮用水的安全。
Treatment efficiencies of high algae period water from Taihu lake by Coagulation- Uhrafiltration ozonation - activated carbon adsorption process were investgated. The results showed that average effluent turbidity of coagulation-ultrafihration was 0.02 NTU which was far below upper limit of 《hygienic standard for drinking water》（GB5749-2006）with unstable influent turbidity. The average removal efficiency of CODMn reached 90.5% and the average CODMn of source water decreased to 1.16mg/L by the combined processes which meeted the 《hygienic standard for drinking water》（GB5749-2006）.The average total removal efficiency of UV25d was 94.3 % .The average TON in treated water was 2 which is lower than the upper limit of Q/ZLS001-1998.No alage could be detected in treated water and biological stability of water quality could be guaranteed. The combined processes can maximize their respective function and ensure the safety of drinking water.
