摘　　要： 为缓解丁山河流域深惠交接断面水环境压力,保障东江饮用水安全,改善流域内水环境质量,开展了丁山河水环境整治工程建设,工程设计规模为4×104m3/d。在河道设橡胶坝拦截,受污染河水经泵站提升进入河道旁路净化处理系统,采用生物接触氧化/人工湿地深度处理组合工艺净化处理后回补河道。详述了工程工艺流程、主要构筑物的设计参数及工艺特点。该系统耐冲击负荷能力强、处理能效好,出水水质基本达到地表水Ⅴ类标准,保障了下游水体水质安全。 In order to relieve water environment pressure at the section where Shenzhen and Huizhou join in Dingshan River Basin, protect the water safety of Dongjiang River and improve the water environment quality in this basin, the Dingshan River water environment renovation project with a design capacity of 4 x l04 m3/d was constructed. In the help of rubber dam, polluted water was pumped into nearby treatment system, and the water was discharged to river for ecological use after treated by the inte- grated process of biological contact oxidation and constructed wetland. The treatment process flow, design parameters of each unit and process design characteristics were described. Due to high resistance to shock load and high treatment efficiency, the system effluent could satisfy five class of the surface water quality standard and ensure water body safety.
