摘要:
采用曝气生物滤池(BAF)、气浮和臭氧生物活性炭(BAC)联用技术对太湖原水进行试验.有机物分子量分布测定结果表明:曝气生物滤池单元对分子量小于0.5 kD(道尔顿)的有机物去除率最高,其次是分子量介于1~3 kD的有机物; 气浮单元对分子量大于100 kD的有机物去除率最高; 臭氧氧化单元对分子量大于3 kD的有机物去除率较高,而对于小于3 kD的有机物不但不能去除,反而有所增加; 生物活性炭单元对分子量小于10 kD的有机物均能有效去除,分子量越小,去除率越高.综合评价认为:曝气生物滤池、气浮和臭氧生物活性炭联用技术处理微污染水源水的净水工艺是合理的.
Abstract:
The experiments of purification of Taihu Lake water through biological aerated filter(BAF), flotation, ozone and biological activated carbon(BAC)were conducted. The results of the distribution of molecular weight(MW)of organics show that in BAF unit the removal rate reaches a maximum for organic matters with molecular weight below 0.5 kD(Dalton), followed by those with molecular weight of 1 to 3 kD. In flotation unit, the maximum removal rate of organic matters is referred to those with molecular weight above 100 kD. With ozone oxidation unit, the organic matters with molecular weight above 3 kD can be removed effectively, however the organic matters with molecular weight below 3 kD would even increase instead of removal. In BAC unit, the organic matters with molecular weight below 10 kD can be removed effectively, and the smaller the molecular weight, the higher the removal rate. Comprehensive judgment shows that the purification process of BAF combined with ozone and BAC is reasonable.
