摘　　要：为解决农村生活污水处理在技术和管理层面的差异性,采用以新型薄膜材料作为微生物载体的微动力固定床薄膜生物法。通过对生物反应器挂膜方法和挂膜后膜卷间隙、进水水力负荷、循环时间、进水污染物负荷等因素的条件下对于氨氮污染物的去除率来确定农村污水排放分级达标要求下的工艺措施和固定床薄膜生物反应器的运行控制参数。研究表明膜卷间隙为5 mm时,装置对氨氮的去除效果较好。在水力负荷为2.82 m^(3)/(m^(2)·h)时,系统对氨氮的去除效果达到最佳。在循环时间为3 h系统对氨氮的去除效果达到最佳。在4种污染物负荷下反应器有较强的扛冲击能力。In order to solve the differences in technology and management of rural domestic sewage treatment,the micro-dynamic fixed-bed membrane biological method using a new type of film material as a microbial carrier was adopted.The technological measures and the operation control parameters of the fixed-bed membrane bioreactor were determined by the removal rates of ammonia nitrogen and total nitrogen pollutants under the conditions of the membrane hanging method,membrane roll gap,influent hydraulic load,cycle time,influent pollutant load and water temperature.The results show that when the membrane gap is 5 mm,the removal effect of ammonia nitrogen is better.When the hydraulic load is 2.82 m^(3)/(m^(2)·h),the removal effect of ammonia nitrogen is the best.The removal effect of ammonia nitrogen is the best when the cycle time is 3 h.The reactor has strong impact carrying capacity under 4 kinds of pollutant loads.
