【摘要】 采用黑曲霉为发酵剂对活性污泥进行全程无公害处理并对各种病原菌的生长变化进行监测。结果表明病原菌总量在发酵过程中呈"马鞍型"变化。由于不同堆肥处理组合的C/N比及添加辅料的不同,导致各种病原菌的生长规律出现差异;采用黑曲霉处理城市活性污泥可使病原菌数目减少,但不能达到完全杀灭的目的;对发酵污泥进行200℃高温物理处理后,病原菌存活量为零。因而活性污泥在堆肥后必须经过高温物理处理才能达到安全化和资源化。更多还原

【Abstract】 This paper made a study of the variety regulation of pathogens in the activated sludge through biological fermentation using Aspergillus niger as zymophyte.The results showed that the quantity of the pathogens changed as ″shadow″.Different pathogens have specific growth regulations because of C/N and additives of different composts.The number of pathogens may be reduced by fermentation but could not be completely exterminated.So 200℃ heat physical decomposition to activated sludge must be applied to attain the aim of safety and recycling.更多还原
