摘要
广东省惠阳区黄沙河河道水质旁路处理系统近期设计处理规模为1.0×104m3/d,采用A2/O与人工湿地处理工艺,第一阶段设计出水水质执行《地表水环境质量标准》(GB 3838—2002)Ⅴ类标准(其中NH3-N≤4.4 mg/L)。介绍了该工程的概况、工艺设计参数,总结分析了工艺设计的特点、运行效果及技术经济指标。工程运行结果表明,该工艺处理效果良好,适合在广东省各污染河道推广。
The Huangsha River water quality bypass treatment system in Huiyang district of Huizhou City, with a recent design capacity of 1.0×10^4 m3/d, adopts the A2/O and constructed wetland treatment process. The first stage design effluent should meet the class V criteria specified in the Environ- mental Quality Standards for Surface Water （GB 3838 -2002）, in which ammonia nitrogen was equal to or less than 4.4 mg/L. The general situation of the project and process design parameters were intro- duced, and the characteristics of process design, operation effect and technical and economic indicators were analyzed and summarized. The project operation results showed that the process had excellent treat-ment effect and was suitable for polluted river water in Guangdong Province.
