改良型SBR系统处理染料废水的研究

通过试验考察了两种改良型序批式间歇反应器-SBR-系统——“厌氧、好氧”交替运行系统-系统1-和“厌氧+好氧”串联二级系统-系统2-的运行过程,分析了影响系统运行效果的因素,比较了两个系统厌氧阶段、好氧阶段及全过程处理效果的差异,并分析了造成差异的原因.结果表明,两个系统均具有适应能力强、稳定性能好、能够有效地降解污染物的特点;污泥浓度、碳源数量、环境温度均影响系统的运行效果;系统1的厌氧阶段比系统2更有效,系统2的好氧阶段比系统1更有效,系统2的全过程处理效率更高;分析认为生物相组成情况的不同是导致两个系统处理效果差异的主要原因.

Studies on improved SBRsystems in treating dyeing wastewater.

Through experiment, the performing courses of two kinds of improved SBR systems-"anaerobic-aerobic"alternative system(System 1) and "anaerobic+aerobic" tandem system(System 2), were investigated. The factors influencing the performing efficiency of each system were analyzed. The discrepancy of the treating efficiency between the anaerobic phase、 aerobic phase and the whole process of these two systems was compared and the reason of this discrepancy was analyzed. The results show that both systems have the characteristics of powerful adaptability、 sound stability and effective degradation of pollutants. Sludge concentration、carbon source and environmental temperature influence the effects of system performance. The efficiency of the anaerobic phase of System 1 is better than that of System 2, while the efficiency of the aerobic phase of System 2 is better than that of System 1; and the treating efficiency of the whole process of System 2 is higher. Through analysis, the different composition of the microorganism bio-faces of these two systems is regarded as the main cause of the discrepancy of their treating efficiency.
