【正文】 ombining t he volatile content , ash and element of sludge , factors t hat affected sludge heat value was investigated , and t hen the influence of moist ure on sludge heat value utili2 zation was also discussed. The experiment showed t hat t he result s of element analysi s and calorimeter are accordant . The sl udge volatile content examination was infl uenced by t he wastewater qualit y , drainage system , wastewater t reating process and sl udge feat ure , and t hen effected t he sl udge heat val ue. It was suggested t hat t he sludge ing f rom wastewater t reat ment plant s of bined drainage system and digested sl udge were not fit for bustion. St udy result s f urt her indicated t hat when t he sewage sl udge could be incinerated by it self , t he moi st ure should not be higher t han 68 %. From t he analyses of sl udge element , we find t hat alt hough t he sl udge volatile content of each plant are different , but t he stoichiomet ric form of element i s basically consi stent , we can roughly denote t he stoichiomet ric formula of sewage sludge volatile content CH1. 72 O0. 55 N0. 12 S0. 03 . Keywor ds: WWTPs 。通過元素分析發(fā)現(xiàn),不同污水處理廠污泥揮發(fā)分元素的計(jì)量組成基本一致,可用計(jì)量化學(xué)式CH1. 72 O0. 55 N0. 12 S0. 03 粗略地表示重慶市主城區(qū)污水處理廠污泥揮發(fā)分的組成。污水水質(zhì)、排水體制、污水及污泥處理工藝通過影響污泥揮發(fā)分的含量而影響污泥熱值, 建議消化污泥和合流制區(qū)域污水處理廠污泥不宜采用焚燒處理。
