摘要
以具有污泥减量效果的A+OSA(Anoxia-Oxic-Settling-Anaerobic)工艺作为研究对象,通过对系统内微生物生化反应放热值的测定研究来探索A+OSA工艺的污泥减量发生的模式。结果表明:A+OSA系统的含能水平要高于AO参照系统;解耦联是A+OSA工艺污泥减量原因之一;A+OSA系统的污泥减量是在贮泥池内的污泥衰减与解偶联的共同作用下完成的。
As one of uncoupling technologies,OSA（Oxic-Settling-Anaerobic） process has many advantages,such as low sludge production,good sludge sedimentation performance,high removal rate of CODcr,helping high concentrated organic wastewater treatment,and so on.However,at present,sludge reduction mechanism of OSA process is still a matter of controversy.OSA process in practical engineering application is limited.In this experiment,we choose A＋OSA（Anoxia-Oxic-Settling-Anaerobic） process which has the effect of sludge reduction as the research object,studying the calorific value form microbes＇ biochemical reactions of A＋OSA system,exploring sludge reduction occurred pattern of A＋OSA process.
