好氧-沉淀-厌氧过程在污泥减量化应用中的研究

RESEARCH ON THE APPLICATION OF OXIC-SETTLING-ANAEROBIC PROCESS IN REDUCTION OF EXCESS SLUDGE PRODUCTION

活性污泥法是目前世界上应用最广泛的污水生物处理技术,它具有处理效果好,运行成本低的优点,但在运行过程中会产生大量的剩余污泥,而污泥的处理与处置费用巨大。所以剩余污泥减量化尤为重要。目前,已处于研究状态的污泥减量化技术很多,其中好氧—沉淀—厌氧(OSA)处理技术由于其减量效果好和环境影响小的特点而得到很多研究者的青睐。

Activated sludge technology is a widely used biotechnology for wastewater treatment. It has advantages of good effect and low operation cost,but lots of excess sludge is produced and the cost of sludge treatment is very high. Therefore the reduction of excess sludge production is very important. At present,a large number of sludge reduction technologies are being researched,including oxic-settling-anaerobic process (OSA) which has found favor in the eyes of many researchers because of its good effect and little influence on the environment.
