摘要
乡镇地区的生活污水富含氮磷等营养性物质,水生生物通过附着、吸收、积累、降解作用,可高效、快速去除水体中的营养物质。江苏省宝应县曹甸镇污水处理厂采用生物接触氧化曝气处理+水生植物综合处理工艺,每日处理3 000 m3生活污水,排水达到国家一级排放标准。利用水生植物法净化乡镇生活污水具有投资少,维护和运行费用低,管理简便,污水处理效果好,可改善和恢复生态环境等优点,是一种低成本高效益的生态工程技术。
Water pollution in small towns is rich in nutrient substance, such as azote and phosphor. Aquatic plant can remove nutrient substance efficiently and quickly by attaching, absorbing, accumulating and degradation. Swage treatment Factory of Caodian Town Baiying County, Jiangsu adopts bio - contact ＆ nbspoxidation aeration and complex treatment of aquatic plants. It deals with 3000m^3 polluted water a day and reaches state high standard. Wastewater treatment system based on aquatic plant is an ecological engineering technology characterized by less dissipation of energy, low investment economical operation, simple administration, high efficiency.
