| 摘 要： | 本文通过分析吸附活性污泥法的生物化学原理和物理化学原理,探讨了该工艺对废水中有机物的去除机理。在A级,废水中的溶解性有机物主要通过原核细菌的生物代谢作用去除,悬浮有机物和胶体有机物则主要通过生物吸附和絮凝沉淀去除。在B级,原生动物和后生动物通过活化细菌、改善活性污泥的沉降性能和吞食游离细菌来提高出水水质。

| Abstract: | In this paper we approach the mechanism of removing organic material of wastewater in adsorptionbio- activated sludge process by means of analyzing the principles of biochemistry and physico-chemistry. In A stage, most of soluble organic material is removed by biological metabolism of prokaryotic bacteria, most of suspended and colloidal organic material is removed by biological adsorption and flocculation settling. In B stage, protoza and micro rotifers increase the quality of effluent by activating bacteria, improving function of activated sludge' s settling and swallowing dissociated bacteria. |
