%X According to the kinetics of biological process,this paper has proposed the determination of the quantity of nonbiodegradable substances in wastewater,which is then applied to the process of an anaerobic treatment and an aerobic treatment respectively. The results are as follows:(1) In the anaerobic treatment of cotton pulp black liquor with an UASB reactor,when the COD concentration of the influent is 10-13g/L,the concentration of nonbiodegradable subsctances,through measuring and calculating,is 4.147g COD/L. Thus,the average value of the maximum COD removal is 63.3%. Meanwhile,in the batch experiment of the anaerobic treatment of cotton pulp black liquor,the result obtained in the same way it the maximum COD removal can be 63.9%,which further supports this result.(2) As for the wine lees with the activated sludge process,the average value of the maximum COD removal can be expected to be 86.8%.
