摘要
介绍了氯消毒、二氧化氯消毒、氯氨消毒和UV消毒方式的优点及缺陷,并对4种消毒方式的工程投资估算、年运行费用和费用现值进行了技术经济比较。分析结果表明:当水厂处理规模<1.2×104m3/d时,二氧化氯消毒在经济上优于其他3种消毒方式;当处理规模>1.2×104m3/d时,液氯消毒方式较为经济;UV消毒方式的费用现值约为其他消毒方式的1.3-2倍。
The advantages and defects of various disinfection techniques with chlorine, chlorine dioxide, chloramines, and UV were introduced, and the engineering investment, annual operational cost and net present value （NPV） of the four disinfection techniques were compared in technical and economic aspects. The analysis results show that chlorine dioxide disinfection is the best way in economic aspect for water treatment plants （WTPs） with a capacity of less than 1.2 ×10^4m^3/d, while for the WTPs with a capacity of more than 1.2 ×10^4m^3/d, chlorine disinfection is more economic ; and the NPV of UV disinfection is about 1.3 to 2 times than all other disinfection systems.
