| 摘 要： | 对比研究了藻菌混合包埋(MI)和藻菌分层包埋SI1(藻外菌内)、SI2(藻内菌外)固定化藻菌对养殖废水中氮、磷的去除效果,以及光照、温度对3种处理脱氮去磷的影响。试验结果表明,在设计条件下处理72 h MI与SI2对氮的去除率分别为91.20%和90.77%,显著高于SI1。MI与SI1的去磷效果显著强于SI2,处理72 h后2者对磷的去除率分别为90.31%和84.78%,SI2仅为32.09%。当[光]照度6 000 lx时,SI2氮去除率在88%以上,显著高于MI与SI1;[光]照度6 000 lx时,SI2与MI对氮的去除率均高于89%,显著高于SI1。MI与SI1对磷的去除率在85%以上,显著高于SI2。MI、SI1、SI2去除氮、磷的最佳温度为20~30℃。 |

| Abstract: | A comparison study was carried out on effects of mixing-immobilization(MI) and stratifying-immobilization(SI) of algae and bacteria removing nitrogen and phosphorus from aquacultural wastewater and influence of light intensity and temperature on the effects.Stratifying-immobilization was done in two forms,SI1and SI2.The former had algae in the outer layer and bacteria in the inner one,whereas the latter did reversely.Results show that under given conditions for 72 h,MI and SI2 removed 91.20% and 90.77%,resp... |
