摘要
采用BAF预处理/常规与常规/臭氧—活性炭工艺处理微污染水,并从对主要污染物的去除效果、装置运行维护及经济性这三个方面对这两种处理工艺进行了比较。结果表明,两种工艺对NH3-N的去除率均达到90%以上,对CODMn的去除率相当,皆为61%左右;两种工艺在运行维护方面各有利弊;与臭氧—活性炭工艺相比,BAF预处理工艺在投资上节省40%以上、在运行费用上节省70%以上、在占地面积上节省40%以上。
BAF/conventional water purification and conventional water purification/O3 - BAC were used to treat the micropolluted source water, and the removal efficiencies of main pollutants, the op- eration and maintenance of device and the economic analysis were compared. The removal rates of NH3 - N and CODMn by the two processes are both above 90% and about 61% respectively. The two processes have their own advantages and disadvantages in operation and maintenance. The investment, operation cost and land occupation area of BAF are above 40% , 70% and 40% less than those of O3 - BAC.
