摘    要:潜流型人工湿地污水处理系统具有一定的氮净化能力,总氮(TN)去除率分别为4934%(芦苇系统)、4549%(茭白系统)、3869%(无植物系统).湿地中氮转化细菌丰富,氨化细菌为106—107cfu/g(土壤),亚硝化菌为103—105MPN/g(土壤),硝化菌103—104MPN/g(土壤),反硝化细菌为104—106MPN/g(土壤).亚硝化菌数量有植物系统高于无植物系统,前部高于后部,硝化菌数量有植物系统高于无植物系统,中后部高于前部.

关 键 词:人工湿地  TN去除  氮转化细菌

Abstract:Subsurface flow constructed wetlands wastewater treatment system has the capacity of nitrogen removal to a certain degree.Its respective removal rations of total nitrogen(TN) were 49.34% (Phragmites australis system),45.49%( Zizsnia latifolia system) and 38.69%(unplanted system).There were abundant nitrogen transformation bacteria in wetlands.10 6 10 7cfu/g(soil),10 3 10 5MPN/g(soil),10 3 10 4MPN/g(soil) and 10 4 10 6MPN/g(soil),were obtained respectively for ammonifying bacteria in planted system and were large than those of the unplanted system.Its amount was larger in the front part of system than that of the back part.The amount of nitrate bacteria in planted system was also larger than that of the unplanted system,but its amount was larger in the middle part of system than that of the front part.
Keywords:constructed wetland  TN removal  nitrogen transformation bacteria
