【摘要】 对高效藻类塘系统处理太湖地区农村生活污水进行了试验研究,实验系统由沉淀水箱、高效藻类塘和水生生物塘等组成。结果表明:高效藻类塘出水COD浓度受藻类生长影响较大,但出水溶解性COD比较稳定,平均去除率在70%以上。氨氮的去除效果好,平均去除率为93%,氨氮主要通过硝化、挥发和生物同化吸收三种途径去除。塘内磷主要通过沉淀去除,总磷平均去除率在50%左右。水生生物塘不仅能有效去除高效藻类塘出水中的藻类和悬浮物,而且能进一步降低水中有机物、氮、磷等污染物浓度。冬季水力停留时间的延长对保障系统的整体运行效果是有效的。高效藻类塘系统用来处理太湖地区农村生活污水具有一定的应用前景。更多还原

【Abstract】 A tentative research on rural domestical sewage treatment by highly effective algal pond was done. The results showed that the effluent COD concentration of highly effective pond was affected greatly by algal, but the COD solubility in effluent was more stable and the average removal rate was over 70%; ammonia-nitrogen removal effect was better than average removal rate of 93%; total phosphrus removal rate was about 50%. The application of highly effective algal pond to treatment of domestical sewage possesses better prospect in the rural area.更多还原
