摘　　要：从西藏自治区县域生活污水的特点及居民的生活习惯出发,构建处理能力为1 000 m3/d的温室型多介质人工湿地示范工程,通过温室型多介质人工湿地与室外水平潜流人工湿地的组合工艺处理县域生活污水,以实现对该区域生活污水的净化,并用于补充附近水环境的生态用水。监测数据表明,温室内多介质人工湿地整个运行期间COD平均出水浓度为40.92 mg/L、氨氮平均出水浓度为4.28 mg/L、总氮平均出水浓度为8.20 mg/L、总磷平均出水浓度为0.40 mg/L,出水质量高于《城镇污水处理厂污染物排放标准(GB 18918—2002)》(以下简称《标准》)一级A标准。系统有效克服了西藏地区高寒缺氧的气候条件,具有高效、稳定的去污性能。另外,室外潜流人工湿地最终COD(28.02 mg/L)、总磷(0.24 mg/L)出水水质均达到《地表水环境质量标准》(GB 3838—2002)的Ⅳ类标准。鉴于氮磷元素是植物生长的必需元素,工程出水可回用补充湿地。本工程的运行成功对于西藏自治区县域污水的人工湿地处理具有一定的工程示范作用和推广应用价值。Based on the characteristics of domestic sewage in Tibet Autonomous Region and the living habits of residents,a greenhouse multi-medium with a treatment capacity of 1000 m3/d was constructed Constructed wetland demonstration project,through the combination of greenhouse multi-media constructed wetland and outdoor horizontal subsurface fl ow constructed wetland treatment of domestic sewage in the county,in order to achieve the purifi cation of domestic sewage in the area and to supplement the ecological water of the nearby water environment.Monitoring data show that the average effl uent concentration of COD,ammonia nitrogen,total nitrogen and total phosphorus is 40.92 mg/L,4.28 mg/L,8.20 mg/L,and 0.40 mg/L during the whole operation of the multi-media constructed wetland in the greenhouse.The effl uent quality is higher than the Discharge Standard for Pollutants in Urban Sewage Treatment Plants(GB 18918—2002)(hereinafter referred to as the"Standard")Grade A standard,the system eff ectively overcomes the climatic conditions of high cold and hypoxia in Tibet,and has effi cient and stable deconsolidation performance.In addition,the fi nal COD(28.02 mg/L)and total phosphorus(0.24 mg/L)effl uent quality of the outdoor subsurface fl ow constructed wetland reached the Class IV standard of the Surface Water Environmental Quality Standard(GB 3838—2002).In view of the nitrogen and phosphorus elements are necessary for plant growth,the project effl uent can be reused to supplement the wetland.The successful operation of this project has a certain demonstration role and application value for the treatment of county sewage in constructed wetland in Tibet Autonomous Region.
