摘要 通過对比试验研究聚氨酯、竹纤维、火山岩、沸石、牡蛎壳5种填料在污水处理过程中的实际效果。以填料的优化配置为基础研发一种基于竹纤维的一体化脱氮除磷生活污水处理装置，并开展小试、中试研究。小试试验中，火山岩填料的出水COD平均浓度最低，为27.56 mg/L，平均去除率为91.64%;混合填料对NH4+-N的去除效果最好，出水平均浓度为4.80 mg/L，平均去除率为77.66%;沸石填料对TN的去除效果最好，出水平均浓度为9.53 mg/L，平均去除率为71.44%;混合填料对TP的去除效果最好，其出水平均浓度为1.88 mg/L，平均去除率达57.84%。中试试验中，出水COD、NH4+-N、TN、TP的平均浓度分别为50.73、11.03、13.10和1.59 mg/L，相应的平均去除率分别为86.51%、59.53%、61.57%和43.92%，出水满足《农村生活污水处理设施水污染物排放标准》DB 33/973—2015一级标准。

Abstract The actual effect of five kinds of fillers （polyurethane， bamboo fiber， volcanic rock， zeolite and oyster shell） in the process of wastewater treatment was studied through comparative experiments. Based on the optimal allocation of fillers， an integrated nitrogen and phosphorus removal domestic sewage treatment device based on bamboo fiber was developed， and the small-scale and pilot studies were carried out. In the small-scale test， the average concentration of COD in the effluent of volcanic rock packing was the lowest， which was 27.56 mg/L， with an average removal rate of 91.64%;the mixed packing had the best removal effect on NH4+-N， which was 4.80 mg/L， with an average removal rate of 77.66%;the zeolite packing had the best removal effect on TN， which was 9.53 mg/L， with an average removal rate of 71.44%;the mixed packing had the best removal effect on TP 1.88 mg/L， the average removal rate reached 57.84%. In the pilot test， the average concentrations of COD， NH4+-N， TN and TP in the effluent were 50.73， 11.03， 13.10 and 1.59 mg/L respectively， and the corresponding average removal rates were 86.51%， 59.53%， 61.57% and 43.92% respectively. The effluent met the first-level standard of DB 33/973-2015 in the Water Pollutant Discharge Standard for Rural Domestic Sewage Treatment Facilities.

随着我国农村经济水平的快速发展，村民生活水平日益提高，其生活方式也发生改变，现代化厨卫设施使用覆盖率增加，伴随而来的生活污水排放量亦显著增加[1]。据统计，20世纪90年代我国的生活污水产生排放量超过同时期的工业废水排放量，成为主要的水污染源头，未经处理的生活污水随意排放，不仅造成周边地表水体的严重污染，还直接或间接危害人类生存环境及身体健康。常见的城镇污水处理厂由于其建设成本高、运维管理难等因素，再者由于农村生活污水具有分布散、水质水量波动大、随机性强等特点，使得市政污水处理工艺并不适用于广大农村地区的生活污水处理。……
