摘　　要：东营市南郊水厂为国内首家大型浸没式超滤膜水厂,针对其出厂水口感差、嗅味重的特点,于2012年9月全部采用二氧化氯消毒,使出厂水水质得到极大改善,充分保障了居民用水安全。对二氧化氯与液氯消毒出水水质指标进行了对比,结果表明,采用二氧化氯消毒比液氯消毒更能保障饮用水的安全,其中对COD Mn的控制,二氧化氯和液氯效果差不多,二氧化氯稍优于液氯;对氨氮的控制,二氧化氯优势明显,出水氨氮要比使用液氯低50%以上;对THMs的控制,二氧化氯优势明显,出水THMs比使用液氯低一个数量级。Dongying Nanjiao Waterworks is the hrst large-scale waterworks using suDmct^cu ul membrane system in China. Due to poor taste and odor in the finished water, chlorine dioxide has been .used since September 2012 to improve the finished water quality and guarantee the drinking water safety. The quality of drinking water disinfected with chlorine dioxide was compared to that disinfected with liq- uid chlorine. The results showed that chlorine dioxide disinfection was more efficient than liquid chlorine disinfection to ensure drinking water safety. Chlorine dioxide had a slight advantage over liquid chlorine in CODM. control, but a significant advantage over liquid chlorine in ammonia nitrogen control, and am- monia nitrogen in the treated water with chlorine dioxide was more than 50% less than that with liquid chlorine. The control of THMs with chlorine dioxide was an order of magnitude lower than that with liquid chlorine.
