【摘要】 污水处理已趋于多样化,生化处理是较为常规的处理有机物的方法,但是从动力学理论上探索其本质动力学参数关系却是屈指可数.本文通过模拟污水生化处理系统,推导出有机物去除率同有机物降解速率常数、活性污泥浓度及水力停留时间关系的数学模型.结合湘潭某污水处理厂工艺试验数据,把有机物实际去除率与理论去除率作比较.结果表明:通过此模型能够指导生产.更多还原

【Abstract】 Nowdays,the treatment of the sewage tends to become more and more diversified,biochemical treatment is a more conventional method of treating organic matter.However,it is only a handful to explore its intrinsic kinetic parameters from the theory of dynamics.By simulating the sewage biochemical treatment system,the mathematical expressions were obtained,which contained the ralitionship among the removal rate and degradation rate of organic matter,the concentration of activated sludge and the hydraulic stay time.The actual removal rate of organic matter was compared with the theoretical removal rate by using the process data of a sewage treatment plant located in Xiangtan.The results show that this model is very instructive for production.更多还原
