碩士 === 中國文化大學 === 造紙印刷研究所 === 86 === Abstract The earlier scholar thought that the activated sludgeprocess is less effective than trickling filter,chemical oxidation treatment, activated carbon adsorptionand etc. in treating wastewater with organic compoundswhich is difficult to treat. However, this study indicatesthat as long as we can control those factors of activatedsludge process well ,then we can make it easy to approachthe standard of wastewater emission. In this experiment ，we treat the wastewater with theactivated sludge have different concentration then observe the variant. We discuss and control the balance of themicroorganism system by using biodegradation index (BI),and make this system in a better situation to get bettertreatment. We can control the activity of microorganism more easily with biodegradation index (BI). If we judge activityof microorganism by biodegradation index with COD, oxygenrequirement , food to microorganisms ratio and etc., the result will be more correctly.
