摘要
针对污泥处理处置过程中的环境问题和经济问题,将传统的活性污泥工艺(CAS)与好氧—沉淀—厌氧工艺(OSA)对比,研究了两种工艺对污泥减量化的影响,分析了两种工艺对废水中COD浓度、COD去除效率、氨氮浓度及SVI值的影响,并指出OSA工艺运行稳定,抗冲击能力强,其引起的解偶联代谢能促进污泥产率下降。
Aiming at the environmental issues and economic issues in the sludge treatment and disposal process,after comparing the conventional activated sludge process(CAS)and the aerobicprecipitation-anaerobic process(OSA),we studied and analyzed the influence of the two processes to sludge reduction,COD concentration in wastewater,COD removal rate,ammonia concentration and SVI value.Moreover,we presented that,the OSA process was stable,had great resistance to shock,and the uncoupling metabolic caused by OSA could promote sludge yield to decrease.
