On Types and Distribution of Organic Pollutants in Sewage Sludge by GC-MS

Pretreatment and determination factors of the organic pollutants were discussed and optimized,and then the three sewage sludge samples were determined and compared by GC-MS.The results showed that: Alkane was the main pollutants in Mantang river sewage sludge,and the amount of organic pollutants was far lower than the other two;alkane,alkene and alkyne were the main pollutants in Xiannv river sewage sludge,and the amount of organic pollutants was much higher.Consequently,the degree of organic pollution was as Xiannv River's Northern's Mantang River's.Mantang River's is the best to be reused.Because of the existence of the priority of controlled organic pollutants in all,these three sewage sludge should be monitored to prevent from re-pollution comes from long term cumulative effect.
