| 摘 要： | 以两种工业废水为处理对象，在讨论活性污泥系统中DO意义的基础上，研究了DO在分别改变进水浓度和初始污泥浓度条件下的变化规律，即当有机物浓度不再降低时，DO迅速大幅度上升，可作为停止曝气的控制信号。同时还讨论了污泥浓度对有机物降解速率的影响，并对有机物降解和污泥增长进行了动力学分析。

| Abstract: | By using two kinds of industrial wastewater as treatment objects, the changing regularity of DO under conditions of changing the concentration of ingoing water or initial MLSS was studied based on discussing the meaning of DO in activated sludge system. The results show that Do increases rapidly and greatly when organic matter concentrations do not reduce any more, which can be used as control parameter to stop aeration. The influence of MLSS on the rate of organism degradation was discussed, and the kinetic analysis on organism degradation and sludge increase was also made. |
