摘　　要：将传统ABR改进为复合式ABR（HABR），并采用HABR／混凝／生物接触氧化组合工艺处理印染废水，重点考察了HABR的处理效果以及混凝工艺位置的选择。结果表明，通过在ABR中增设填料层、合理分配各反应室的上升流速和增加污泥回流，明显提高了其对印染废水的处理效果；将混凝工艺置于厌氧和好氧工艺之间，从处理效果和成本方面考虑都是最有利的；当印染废水的COD为400～500mg／L、色度为500～600倍、SS为200～250mg／L时，组合工艺对COD、色度和SS的平均去除率分别可达85．4％、95．6％、90．9％，处理效果好且稳定。The anaerobic baffled reactor （ABR） was improved to hybrid ABR （HABR）, and the combined process of HABR, coagulation and biological contact oxidation was used to treat printing and dyeing wastewater. The treatment efficiency of HABR and the selection of coagulation location were especially investigated. The results show that the treatment efficiency of printing and dyeing wastewater is significantly improved by adding media layer, rationally distributing the upflow velocity in each reaction chamber and increasing the sludge return rate in traditional ABR. Placing the coagulation process between anaerobic process and aerobic process is the most favorable in terms of treatment efficiency and cost. When the influent COD, color and SS are 400 to 500 mg/L, 500 to 600 times and 200 to 250 mg/L respectively, the removal rates of COD, color and SS by the combined process are 85.4%, 95.6% and 90.9% respectively, with better and stable treatment efficiency.
