摘　　要：本研究探讨了在常规水处理工艺中选择粉末活性炭投加点的一般规律。研究结果表明，在絮凝池中，当絮体尺度发展到与粉末活性炭颗粒尺度相近时的位置应作为最佳投加点。在该点投加粉末活性炭既可避免竞争吸附，又可使絮体对粉末活性炭颗粒包裹作用最小，可以充分发挥粉末活性炭的吸附效率。Abstract The general rule to select the dosage point of powdered activated carbon (PAC) has been studied as far as conventional water treatment process is concerned. The results show that the best PAC dosage point should be in the position where the size of coagulant flocs in flocculation basin nearly increases to the size of PAC particles and that PAC added in the point can not only avoid the competition of adsorption and coagulation, but also minimize the interference and wrapping caused by flocs. Consequently, the adsorption efficiency of PAC can be fully improved.
