| 摘 要： | 为了考察活性污泥系统对环境pH值变化的响应,采用四个小试SBR反应器进行平行试验,研究了在不同原水pH值和不同瞬时混合后pH值条件下,系统污水处理效果以及污泥沉降性的变化.结果表明,由于许多生化反应(硝化、反硝化、放磷等)都消耗或产生碱度,以及水溶液中普遍存在的离子电离平衡,使活性污泥系统对环境pH值的变化具有很好的调...

| Abstract: | In order to investigate the responses of activated sludge system to pH variation,4 lab-scale sequencing batch reactors(SBR) were used to study the variations of wastewater treatment performance and sludge settle ability under different pH raw wastewaters and different pH after impulsive mixing conditions in parallel.The results showed that,because many biochemical reactions can produce or consume alkalinity,and there existed a lot of ionization equilibriums in aqueous solution,the activated sludge system ha... |
