SBR法间歇式活性污泥系统处理有机废水的实验研究

以生粉和调和油水溶液模拟有机废水,采用SBR(Sequencing Batch Reactor)法对其进行处理,以水样浊度作为评价指标,对SBR反应工序、水样浊度与吸光度的标准曲线以及SBR法对有机废水的处理进行了检测和实验。实验结果表明,SBR反应中曝气池的运行操作由5道工序组成;标准曲线的绘制很好地拟合了水样浊度与吸光度的关系;SBR法对水样有机物的去除率随曝气时间的延长而提高,在曝气3h沉淀1h时,水样有机物的去除率达到71.89%。

Fecula and attemper oil watery solution was selected as simulant organic wastewater, then it was disposed by SBR intermittence activated sludge system, and the turbidity was selected as evaluated index. Some measures and experiments were done on SBR reaction working procedure, the criterion curve of turbidity and absorbency, the disposal on organic wastewater with SBR. The experiment results showed that SBR reaction composed of 5 working procedures; Criterion curve fitted turbidity and absorbency very well; And the removal rates of organic compound increased with the prolonging of aeration time, and in the conditions of 3 hours aeration and 1 hour deposition, the removal rate of organic compound was up to 71.89%.
