Abstract


This article is a team already on the basis of the use of microbial energy kinetic equation than the rate of oxygen consumption to establish contact , and through theoretical analysis and practical analysis demonstrated the possibility of the existence of the economic concentration of dissolved oxygen . Economic dissolved oxygen through model tests and field trials as well as analysis of the reactor is running under the economic dissolved oxygen effect . Firstly, according to the microbial energy kinetic equations obtained than the rate of oxygen consumption change equation : the equation given the the aerobic rate changes in the scope of the concept , and provide a theoretical basis for the choice of the adjustment range of the aeration equipment , proved the most Priority presence of the dissolved oxygen concentration . The concept of economic oxygen transfer coefficient K the La ` and economic concentration of dissolved oxygen , and demonstrate the possibility of the existence of the economic concentration of dissolved oxygen . Oxidation ditch model tests to explore the economic oxygen transfer coefficient for oxidation ditch reaction system applications , provide a simple way to run a set of guiding oxidation ditch wastewater treatment plant energy saving and further verified the presence of economic concentration of dissolved oxygen from the test point . Batch reactor experiments , contrast system with the other run effect of dissolved oxygen concentration in the economic and dissolved oxygen concentrations obtained economic dissolved oxygen concentration is to ensure that the effect of carbon source removal and ammonia oxidation minimum dissolved oxygen concentration and sludge the growth into the testing and demonstration . As an opportunity to run the debugger to an oxidation ditch sewage treatment plant in Guizhou Province in the debugging process , the use of the research presented in this paper , the actual effect of the economic dissolved oxygen test in actual running conditions of the sewage treatment plant , and the economic analysis for the problem of a large quantity of sludge growth . Studies have shown that : oxidation ditch wastewater treatment process to maintain the dissolved oxygen concentration in the aerobic zone economic dissolved oxygen concentration , is able to guarantee the stability of the sewage treatment plant , and reliable operation , and short sludge age , the situation of the remaining large amount of sludge produced , still can bring certain economic benefits . Therefore, the study concluded that is able to guide the process of oxidation ditch sewage treatment plant energy-saving operation and guidance technology designed .
