| 摘 要： | 为了降低氧化沟工艺的运行能耗,采用连续进水间歇曝气的运行方式对某中型氧化沟工艺污水处理厂进行了改造研究.该方式将硝化菌控制在硝化动力学的高效率段,提高了硝化菌的硝化效率,降低了曝气能耗;有效避免了过量曝气,从而降低了出水NO-3-N的浓度,NO-3-N对厌氧区释放磷的影响同时降低,提高了生物除磷效率.研究表明:采用间歇曝气的运行方式,使污水处理厂在出水NH3-N达标的基础上,提高了TN和TP的去除率;经过改造该污水处理厂TN和TP的去除率分别由45%、35%提高到65%和84%;该工艺在不改变原有氧化沟污水处理厂基础设施的基础上,仅对运行方式进行优化调控,使全厂的平均电耗降低了21.5%. |

| Abstract: | In order to reduce operating energy consumption of the oxidation ditch process,a medium sized oxidation ditch wastewater treatment plant(WWTP)was reconstructured and studied with intermittent aeration and continuous flow operation mode.In this way,nitrobacteria were controlled at high efficiency phase in the kinetics of nitrification paragraph,so the efficiency of nitrification nitrification bacteria was improved and the aeration energy was reduced;excessive aeration was effectively avoided,and then the eff... |
