摘　　要：采用静态吸附法研究活性炭和硅藻土对3种实验废水在不同吸附条件下(吸附剂量、时间、pH值)的吸附效果。结果表明活性炭在投加量为40 g/L,振荡时间为1 h,无机、有机、混合样品pH分别为4、6、10时,可使样品色度和COD去除率达到最佳效果;硅藻土在投加量为30 g/L,振荡时间为20 min时,无机、有机、混合样品pH分别为8、4、4时,可使废水COD去除率达50%以上,但色度去除效果较差。实验表明硅藻土和活性炭串联吸附为较优方案。This article researched on the result of dealing with three experiment waste liquid in activated carbon and kieselguhr respectively and discussed on the absorb result of absorbing probed into different condition of absorbing （ absorbs dosage, time, pH）. The method adopted is static adsorptive process. And the result shows that when the activated carbon is throwing in the adding amount of 40 g/L, shaking for l h, the pH of the inorganic, organic, mixed sample is 4,6,10, it can make the chromaticity and COD reach the best result; while when the kieselguhr is shooting in the amount of 30 g/L, shaking for 20 min, the pH of the inorganic, organic, mixed sample is 8 ,4,4, it can make the COD reduction more than 50%, but the chromaticity reduction is relatively worse. The absorbing result of activated carbon and kieselguhr used together is better.
