| 摘 要： | 剩余污泥在厌氧条件下会产生氨氮和磷酸盐,向环境释放引起水体富营养化.本文以南阳市污水处理净化中心污泥浓缩池中的剩余污泥为对象,研究剩余污泥厌氧发酵过程中氮、磷的释放规律,并向厌氧发酵上清液投加镁盐和碱溶液,探讨了磷酸铵镁(MAP)沉淀法回收发酵液中氮、磷的效率.

| Abstract: | Ammonia nitrogen and phosphate are produced from activated excess sludge under anaerobic conditions,and will cause eutrophication upon release to the environment.A study of sludge from a wastewater treatment plant is carried out,to obtain knowledge of the nitrogen and phosphorus release patterns of the excess sludge during anaerobic fermentation and the recycling efficiency of both nitrogen and phosphorus,by adding magnesium salt and alkali solution to the supernatant liquors. |

| Keywords: | excess activated sludge anaerobic fermentation magnesium ammonium phosphate(MAP) |
