本研究探讨了细菌处理城市污水的潜力。本研究共分离了8株在废水琼脂培养基上生长的细菌。经形态学和生化鉴定，这些分离株鉴定为地衣芽孢杆菌NW16、铜绿假单胞菌NS19、假单胞菌sp。NS20，盐生Planococcus salinarum NS23，嗜麦芽寡养单胞菌NS21， Paenibacillus sp。NW9、北方芽孢杆菌 NS3和亲水气单胞菌 NS17。< em > B。licheniformis NW16除氨态氮外，其余菌株对各参数的还原潜力最大。地衣芽胞杆菌 NW16和亲水气单胞菌NS17的BOD降幅最大(42.86%)。< em > B。licheniformis NW16和Paenibacillus sp. NW9的COD分别降低82.76%和81.61%。< em > B。 licheniformis NW16, P. salinarum NS23 and Aeromonas hydrophilia NS17 showed reduction in nitrate ranging from 17.36%-63.64%. All the isolates have potential to reduced phosphate from 17.55% -72.3%. B. licheniformis NW16, Ps. aeruginosa NS19, Pseudomonas sp. NS20, Paenibacillus sp. NW9 and Aeromonas hydrophilia NS17 showed reduction in TSS ranging from 42.69%-79.94%. B. licheniformis NW16, Ps. aeruginosa NS19, Pseudomonas sp. NS20, S. maltophilia NS21 and Paenibacillus sp. NW9 showed reduction in TDS ranging from 14%-81.4%.
