摘　　要：用改性粉煤灰处理污水需要较高的能耗和设备要求,而且会对环境造成二次污染,因此研究原始工业废弃粉煤灰在不同搅拌时间、灰水比、粒径和p H值条件下对乌梁素海富营养化水体中COD和TP的去除效果。结果表明:当粉煤灰搅拌时间为4 h,灰水比为1∶11,粒径小于0.150 mm,不调节p H值的条件下,能同时对COD和TP有较好的去除效果,使富营养化水体水质有明显改善。初步证明原始粉煤灰可以在一定程度上解决富营养化水体中COD和TP的污染问题,可以减少粉煤灰改性过程中产生的一系列弊端。Modified fly ash treatment requires high energy consumption and equipment requirements, and can cause the environmental pollution by two times. Therefore, this study focused on the COD and TP treatment effect of Wuliangsu Lake eutrophication water by using the original industrial waste fly ash at different stirring time, fly ash and water ratio, fly ash particle size and pH value. The results show that both COD and TP have good treatment effect when the stirring time is 4 hours, and fly ash and water ratio is 1?11, particle size is less than 0.15 millimeter and keep the original pH value in this study, and eutrophicated water quality has been improved significantly. It preliminarily proves that the original fly ash solves the pollution problem of TP and COD in a certain degree, which reduces a series of problems caused by modified fly ash.
