灰关联分析法在饮用水处理工艺优选中的应用

Application of grey relativity analytical method in optimization of drinking water treatment technics

为得到饮用水处理工艺的最优化方案,对灰关联分析法进行了研究,并将其应用于天津市滦河水高藻期饮用水处理工程优选分析,得出了两套最优工艺方案,分别为"HPAC强化混凝气浮-过滤"和"HPAC强化混凝气浮-过滤-臭氧生物活性炭",其中后者可作为前者出水水质达不到要求时的补充工艺。结果表明,灰关联分析过程简单、分析结果合理可靠,可以广泛应用于水处理工艺优选研究。

In order to obtain the optimum drinking water treatment process, the grey relativity analytical method （GRA） was conducted. As a result, the two optimum technical process which are ＂HPAC enhanced coagulation - flotation - filtration＂ and ＂HPAC enhanced coagulation - flotation - filtration - 03 - BAC process＂ were obtained by applying the grey relativity analytical method （GRA） to the optimization of drinking water treatment process during the high algae -loaden period in Luan fiver of Tianjin. The result shows that grey relativity analytical method with charecterization of convenient and dependable, which can be used in the the optimization of water treatment process.
