Abstract:

As far as biological treatment is concerned,the soluble inert organisms(SI) in the wastewater are the key index indicating whether the effluent can reach the standard or not.Its concentration plays an important role in the treatment method selection and discharge standard establishment.At present,there are five kinds of for SIdetermination methods,namely,extended aeration,effluent approximation,parallel test,mass balance and regression calculation.The principle and advantages and disadvantages of each method are introduced.In the integrated consideration of mathematical model structure and the simplicity and reliability of the method,appropriate SIdetermination method is selected.According to the results from literature data,the actual SIconcentration of domestic sewage wastewater is usually in the range of 10-40 mg/L,while that in the industrial wastewater is greatly influenced as from 50 mg/L to 3 000 mg/L

摘要：

对生物处理系统而言,污水中的溶解性惰性有机物含量(SI)是出水能否达标的关键性指标,其浓度测定对处理方法的选择和排放标准的制定具有重要意义。目前污水中SI的测定方法主要有延时曝气法、出水近似法、平行试验法、物料平衡法和回归计算法5种。介绍了各种方法的原理及优缺点,在综合考虑数学模型结构及方法简单可靠两方面的要求后提出了适用的方法。对文献数据统计结果表明,城市污水的SI实际质量浓度通常在10～40mg/L,而工业废水中SI受行业影响很大,范围为50～3000mg/L。
