摘要
本文测定了几种工业废水可生化指标BOD_5/COD比值和相对耗氧速率,根据模拟生物塘的动态运行试验结果,提出了以耗氧速率R%作为可生化性判定指标,它比BOD_5/COD比值测定快,方法简便,更接近实际,并得出两个指标与生物塘COD去除率之间相关性的线性回归方程,为选择废水生物塘处理方案、预估其对COD去除效率提供了理论依据。
The biodegradability judge indes BOD_5/COD and the relative oxygen consumption rate (R%) of several kinds of industrial wastewater are determined in this paper. Based on the dynamic test results of the simulated biological oxidation pond treatment, the relative oxygen consumption rate (R%) as a biodegradability judge index is proposed, which is Faster and easier to be determined and nearer to reality than BOD_5/ COD, and then the linear regression equations of the relativities between the judge index and the COD removal rate of the biological oxidation pond treatment are studied, which provide a theoretical basis for choosing the project of the biological oxidation pond treatment of wastewater and for estimating the efficiency of the COD removal rate.
