摘要
对江苏省210个农村生活污水示范工程的调查分析结果表明,目前江苏省农村建设的生活污水处理工程的技术主要有生物技术、生态技术和生物生态组合技术三种类型。三个典型技术的示范工程对污水中总氮和总磷的处理效果呈显著性差异,对总氮的处理率都在13:00—15:00时达到最高,不同时段对总磷的处理率差异不显著。三种技术中,生态技术模式对于总氮和总磷的平均去除率分别为82.5%和92.33%,明显高于其他两种技术,且单位体积污水处理成本最低。针对江苏省农村的特点,适宜采用经济有效、简便易行、节约资源、工艺可靠且能够与当地自然环境高度融合的污水生态处理技术,并在污水处理工程运行过程中加强管理,建立有效的资金投入机制和运营管理机制,以保证正常运行,才能达到预期的处理效果,减少农村环境的氮磷负荷。
The objective of this study is to research the rural sewage treatment techniques mode and purifying effect of nitrogen and phosphorus in Jiangsu Province.All the typical demonstration projects of rural domestic wastewater treatment at 210 different counties of Jiangsu Province were investigated.They were classified three types,including biotechnology,eco-technology and biological and ecological combination technology.The differences were significant in remove efficiency of TN and TP in swage among three typical technology demonstration projects,and the rate of TN treatment was highest from 13：00 to 15：00,while no significant were found in TP treatment.The rates of TN and TP remove by biotechnology were 82.5% and 92.33% respectively,higher than the other two technologies,and the cost of sewage treatment per unit volume were lowest.In view of the characteristic of rural area in Jiangsu Province,economical,simple,resource saving and reliable ecological wastewater treatment technology with fusion of natural environment could be adopted.It was necessary to establish an effective management mechanism,to ensure the normal operation of sewage treatment project,and to achieve the desired effect and reduce the nitrogen and phosphorus loading in rural environment.
