摘要:
以环境工程中心污质分离器中的好氧污泥为研究对象，经预处理及厌氧处理甲烷氯化物废水中的化学需氧量（COD）作为监测对象，用生物降解法处理工业废水，对混合液悬浮固体质量浓度为9.3g/L，混合液挥发性悬浮固体质量浓度为8.6g/L，COD为300 mg/L的好氧污泥125 mL与50 mL经预处理及厌氧处理的甲烷氯化物废水于烧杯中，定时取样，测定COD值。在低浓度条件下，利用劳伦斯麦卡蒂方程，用整体速率常数表征水中有机污染物的降解速率，通过计算反应级数、最大比降解速率和饱和常数来研究降解机理。结果表明：废水中三氯甲烷的降解需要诱导酶来完成，将好氧污泥中的微生物看作一个整体。甲烷氯化物好氧微生物降解动力学中，底物利用速率与底物浓度之间的关系式在整个浓度区间上都是连续的，反应级数为0.6426，最大比降解速率为3.8，饱和常数为305.45。
Abstract:
To explore the aerobic sludge in the water pollution separator of the environmental engineering center, chemical oxygen demand (COD) of the pre-treated and anaerobic treated methane chloride wastewater was used as a monitoring object. The industrial wastewater was dealt with bio-degradation. The aerobic sludge抯 mixed liquid suspended solids and mixed liquor volatile suspended solids is 9.3 g/L and 8.6 g/L, and the COD value is 300mg/L. Methane chloride wastewater was experienced pre-treated and anaerobic treated. 125mL of aerobic sludge and 50 mL of methane chloride wastewater were mixed together in a beaker. The COD value was measured with the same time interval. According to the Lawrence ?McCarty equation, the degradation rate of organic pollutants in water were characterized with the overall rate constant and degradation mechanism was studied via calculating the reaction order, the maximum degradation rate and saturation constant. The results show that the degradation of methane chloride in wastewater needs the adaptive enzyme; the microorganism in aerobic sludge are seen as a whole. In the aerobic microorganism degradation kinetics of the methane chloride, the relationship of the saturation constant and the substrate concentration is continuous during the whole concentration range in the reaction order of 0.6426, the maximum degradation rate of 3.8 and the saturation constant saturation constant of 305.45
