污水中颗粒性COD组分的测定方法
Determination Method of Particulate COD Constituents in Wastewater
摘要
Abstract
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%.关键词
