| 摘 要： | 废水生物处理出水中的溶解性微生物产物(SMP)主要产生于基质降解和微生物的内源呼吸过程,它的存在是影响生物处理出水水质和有机物去除率的一个重要因素,已引起人们的普遍关注.简单阐述了SMP的定义,详细探讨了废水生物处理出水中溶解性微生物产物的形成机制与特征.

| Abstract: | The existence of soluble microbial products (SMP) produced by microbial cultures involved in biological wastewater treatment process has been widely investigated. SMPs, which were released from substrate metabolism and microbial endogenous growth, are found to be an important factor which affects the quality of the biologically treated effluent and the degradation of organic compounds. A review concerning the definition, characteristics of SMP and its formation mechanism is presented in the paper. |
