摘　　要：为了探索对富营养化水体的微生物修复方法,采用固定化光合细菌进行人工模拟的富营养化水体处理试验。试验结果表明,接种固定化光合细菌比对照可明显地降低水体中的养分。19d的处理时间,TN、NH4-N、NO3-N、TP和COD的去除率分别达到了65.94%,79.84%,78.80%,62.95%,78.06%,并且接种光合细菌对水体中的藻类也起到一定的抑制作用。接种光合细菌增加了水体的DO和pH值,同时也提高了硝化率以及光合细菌数,而水体中这些因素的变化都与水体中养分的去除效果密切相关。因此富营养化水体修复中接种固定化光合细菌可以起到去除养分的目的。In order to find a feasible biotechnology to remediate eutrophic water,an experiment of treating the artificial eutrophic water with immobilized photosynthetic bacteria was carried out.The results showed that the inoculation of immobilized photosynthetic bacteria could reduce the nutrients in water effectively.The removal rates of TN,NH4-N,NO3-N,TP,and COD were 65.94%,79.84%,78.80%,62.95%,and 78.06%,respectively,after 19 days of treatment.Furthermore,immobilized photosynthetic bacteria inhibited algae growth in the water.The inoculation of immobilized photosynthetic bacteria also increased DO,pH value,the rate of nitrification,and the number of photosynthetic bacteria,and the change of all these factors had an impact on nutrient removal efficiency in water.Therefore,the inoculation of immobilized photosynthetic bacteria could achieve the goal of nutrient removal in the eutrophic water remediation.
