摘　　要： 通过选取3种生物填料作为藻菌生长的载体,研究了3种固定化藻菌共生系统在相同实验条件下对富营养化河水中常规污染物的去除效果。结果表明,在冬季黑臭水时期,3种填料对污染物质去除率整体不高,弹性立体填料对COD、NH3-N、TN、TP的去除率分别为38.9%、36.6%、11.1%、48.6%,盾型填料为25.2%、20.1%、8.1%、35.4%,仿生水草为40.2%、32.8%、11%、47.1%。在夏季轻污染水时期,弹性立体填料对COD、NH3-N、TN、TP的去除率分别为53.8%、56.8%、26.8%、37.6%,盾型填料为44.8%、37.9%、19.3%、35.9%,仿生水草为58.7%、61.7%、51.1%、38.5%。相对而言仿生水草对富营养化河水的处理效果优于弹性立体填料和盾型填料。 Three kinds of bio-media are studied from the efficiency of the difference in treating eutrophic rivers. The results show that the removal efficiency of contamination by three bio-media are low in the period of black-odor rivers in winter. The removal rates of COD, NHa-N, TN and TP in cubic-spring media are 38.9%, 36.6%, 11.1% and 48.6%, respectively, 25.2%, 20. 1%, 8. 1%, 35.4% in scutellate media, 40.2%, 32.8%, 11%, 47. 1% in artificial aquatic in this period. The removal rates of COD, NH3-N, TN, TP in cubic-spring media are 53. 8%, 56. 8%, 26. 8% and 37. 6%, respectively, 44. 8%, 37. 9%, 19. 3% and 35. 9% in scutellate media, 58.7%, 61.7%, 51.1% and 38. 5% in artificial aquatic in the period of slight polluted rivers in spring. Artificial aquatic is better than cubic-spring media and scutellate media in treating eutrophic rivers.
