摘　　要：以天津市某废水处理厂提标改造为基础，建立了1套活性炭回流旋流分离的活性炭吸附一混凝深度处理技术，探究污染物去除机理，系统开展中试研究了药剂投加量、回流量、反洗周期等对污染物的去除效果，中试运行结果表明在PAC34mg／L，活性炭40mg／L，PAM3～4mg／L，药剂成本0．3元／t的情况下，能达到《城镇污水处理厂污染物排放标准》（DB12／599—2015）一级A排放标准，在活性炭回流比超过50%的情况下能一定程度改善处理效果，强化了对亲水性小分子污染物去除，提高处理效率。Based on the upgradation of a sewage treatment plant in Tianjin, a set of activated carbon adsorption-coagulation advanced treatment technology with activated carbon recycling and cyclone separation was established. A pilot study was carried out to explore the pollutant removal mechanism and to examine the effect of chemical dosage, recirculation ratio and backwash cycle on the removal of pollutants. The results of the pilot test showed that the expected treatment performance could be achieved with PAC of 34 mg/L, activated carbon of 40 mg/L, PAM of 3-4 mg/L and chemicals cost of 0. 3 Yuan/m3, reaching the First Grade A standards of ＂Discharge standard of pollutants for municipal wastewater treatment plant＂ （DB/599--2015）. When the activated carbon recirculation ratio is above 50% , the treatment effect can be improved to some extent. The removal of hydrophilic small molecule pollutants is enhanced, and the treatment efficiency is improved.
