Experimental Research on the Optimal Operation Mode of Integrated Oxidation Ditch with Continuous Flow and Intermittent Aeration
The influence of HRT , oxidic time and anoxidic time on the carbon and nitrogen removal of integrated oxidation ditch with continuous flow and intermittent aeration was studied by cross experiment method. The results show that the anoxidic time has the most distinct influence on removal ratio of BOD5 and TN in the system and the oxidic time has a distinct influence on BOD5 as well .When HRT , oxidic time and anoxidic time of the system is 8h , 2 h and 2 h respectively , the effluent quality and the removal ratio for BOD5 are <20 mg/ l and 85. 2 % and for TN are < 20 mg/ l and 55. 5 % respectively.
