摘要

以传统浮岛技术为基础,设计辅以微生物固定化技术和曝气充氧技术的组合浮岛系统,采用静态试验和现场观测相结合的方式,考察组合浮岛与传统浮岛在低温条件下对污染水体的处理效果。静态试验结果显示,组合浮岛对NH_4~--N和COD_(Cr)处理效果较好,NH_4~--N去除率为99.70%,COD_(Cr)去除率为65.78%,由于组合浮岛的小试溶解氧较高,TN去除效率低于传统浮岛。现场观测显示,10月30日至11月10日期间,搭载组合浮岛的试验河段COD_(Cr)、NH_4~--N、TN的平均去除率分别为21.49%、18.51%、13.44%,而同期搭载传统浮岛的对照河段为0%、1.21%、-1.03%。静态试验和现场观测结果均表明生态浮岛在引入微生物载体和曝气装置后,对富营养化水体的修复起到良好效果。
        Based on the traditional floating island technology,a combined floating island system supplemented by microbial immobilization technology and aeration oxygen technology is designed. Static test and field observation are combined to investigate the treatment effect of combined floating island and traditional floating island on polluted water at low temperature. The static test results show that the combined floating island has a better treatment effect on NH_4~+-N and COD_(Cr),with the removal rate of NH_4~+-N being 99.70% and the removal rate of COD_(Cr)being 65.78%. Due to the high dissolved oxygen in the small test of combined floating island,TN removal efficiency is lower than that of traditional floating island. The field observation results show that during solstice on October 30 and November 10,the average removal rates of COD_(Cr),NH_4~+-N and TN in test reach with combined floating islands are 21.49%,18.51% and 13.44% respectively,while the control reach with traditional floating islands is 0%,1.21% and -1.03% respectively. The results of static test and field observation all show that the ecological floating island has a good effect on the restoration of eutrophication water after the introduction of microbial carrier and aeration device.
