摘要:
采用EV生化、生态组合技术处理农村生活污水,对工艺的运行效果和污染物的去除途径及温度对污染物去除率的影响进行了研究分析。一年的观测结果表明,该工艺结合了生物技术和生态工程的优点,能有效去除生活污水中的有机物、氮、磷和粪大肠菌群,且处理效果稳定。温度对有机物、总磷的去除效率影响较小,对总氮、氨氮去除效率影响较大,在冬季低温条件下,总氮、氨氮去除率有所下降。

An application of the Treatment of Rural Domestic Sewage by Combined EV-biochemical and Ecological Technology
Abstract:
Operational efficiencies, removal mechanism and the effect of temperature on removal efficiency for pollutants were studied by combined EV-biochemical and ecological technology for treating rural domestic wastewater. The results of one-year monitoring showed that the process, combined the advantages of biotechnology and ecological engineering, could remove organic matters, nitrogen, phosphorus and fecal coli-group efficiently and stably. Temperature had a significant effect on removal efficiencies of total nitrogen and ammonia nitrogen, whereas influenced organic matters and total phosphorus nonsignificantly. Therefore, the removal efficiencies of total nitrogen and ammonia nitrogen declined under the low temperature in winter.
Key words:  combined biochemical and ecological technology  treatment of rural domestic sewage  temperature  removal effect
