| 摘 要： | 污水中的易生物降解有机物（SS）对生物脱氮除磷过程具有重要意义,也是活性污泥模型中的关键组分。介绍了污水中SS的测定方法,其中好氧呼吸计量法（包括连续OUR法和批式OUR法）和物料平衡法最为常用,而对比发现批式OUR法的测定结果最接近真实值。对文献数据统计表明,城市污水的SS浓度通常为20mg/L-40 mg/L,而工业废水中SS浓度受行业影响很大,SS/COD的波动范围为0.6%-44.0%。

| Abstract: | The readily biodegradable COD（SS）in the wastewater,a key index in the Activated Sludge Model,plays an important role in biological nutrient removal process.This paper summarized various determination methods for the fraction SS,among which aerobic respirometric method（including continuous OUR method and batch OUR method）and mass balance method were the most commonly used methods in wastewater characterization.Based on reported data and practical analysis,the determination result of batch OUR method approaches nearest to the true value.According to the literature data,the actual SS concentration of domestic wastewater is usually in the range of 20 mg/L~40 mg/L,while the ratio SS/COD in the industrial wastewater is greatly fluctuated from 0.6% to 44.0%. |
