摘　　要：采用PACT法处理维生素B1制药废水,重点考察了PACT法对有机物的处理效果以及影响因素．试验结果表明,单独采用粉末活性炭对于COD的吸附平衡时间为3 h;在间歇试验中,粉末活性炭的最佳投加时间为曝气12 h后;当粉末活性炭投加量为500 mg／L,COD的去除率为81．2％,PACT系统的COD相对去除量为普通活性污泥系统的1．68倍;PACT污泥的 SVI(40-54 mL／g)明显低于普通活性污泥的SVI(76-104 mL／g),污泥沉降性能得到改善．PACT-process is used for treatment of pharmaceutical wastewater of vitamin B1 , the effect and influencing ingredient for organic substance removal by PACT- process is primarily investigated. Experiment results show that the absorption equilibrium time for COD is 3h with powder activated carbon only;It is optimal to dose powder activated carbon after a period of 12 hours＇ aeration in the sequencing test. The removal rate for COD is 81.2% with PAC dose of 500 mg/L,the relative removal capacity of COD in PACT system is as 1.68 times as the one of the traditional activated sludge system. The SVI of PACT sludge（40 ～54 mL/g） is much lower than the one of activated sludge（76～ 104 mL/g） ,and the sedimentation capability of sludge is improved.
