广东某农村生活污水一级A达标处理工艺设计

First Level A Standard Treatment Process Design for Guangdong Rural Domestic Sewage

根据广东某农村生活污水处理工程设计出水水质达《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准的要求,选用"酸化水解+MBR+人工湿地"组合处理工艺对该农村生活污水进行处理,该组合工艺对该农村居民区生活污水具有良好的处理效果,出水水质稳定达标。该工程为一级A排放标准条件下小城镇生活污水处理积累了设计经验。

According to the Guangdong a water-quality rural sewage treatment engineering design requirements, which is the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant^GB 18918-2002）, the combined process of hydrolytic acidification, MBR and constructed wetland was adopted to treat the rural sewage Guangdong Province. The combined process had perfect treatment efficiency on rural sewage, the effluent quality is stable and can reach the standard. The project has accumulated design experience of small town sewage treatment for the first level A discharge standard condition.
