摘　　要：污水的颗粒性COD组分包括慢速生物降解组分XS、惰性颗粒性组分XI和异养菌XH，它们会显著影响污水生物处理系统脱氮除磷的碳源供给、污泥产量和固体平衡。该文分类介绍了颗粒性COD组分XS、XI和XH的常用测定方法及其优缺点，总结了国内外生活污水和工业废水中颗粒性COD组分常用测定方法与浓度范围，并针对水质特点提出了处理对策。文献数据统计结果表明生活污水中XS和XI波动范围非常大（10％-60％），而XH的范围为7％-18．9％。The particulate COD fractions in wastewater, including slowly biodegradable fraction Xs, particulate inert fraction XI and heterotrophic biomass XH, have an significant influence on carbon source supply for nutrient removal, sludge production and solid mass balance. The advantages and disadvantages of determination methods for the three particulate COD fractions were introduced and compared. Concentrations and dermination methods of Xs, XI and XH in domestic and industrial wastewater were summarized. According to literature data, Xs and XI proportions of domestic wastewater were greatly fluctuated from about 10% to 60%, while the range of XH proportion in COD was 7% - 18.9%.
