Productive Experimental Research Of Side Channel Integrated Oxidation Ditch

In this paper, operating and adjusting tests (including starting of bacterium tamed, technological adjusting and normal operating) were done for productive side channel integrated oxidation ditch treating high concentration waste water. Commissioning test result under this water quality was analyzed. Phosphor removal effect was studied for productive side channel integrated oxidation ditch without solitude anaerobic zone/stretch. In addition, solid liquid separating and sludge returning effects were studied also. Factors which affected solid liquid separator's operating effect were analyzed. The analysis result tested the prophase solid liquid separating theory. Through analysis of abnormal phenomenon during adjusting process, some practicable and effective technical measures for further improvement and strengthen were provided. The test result showed that the side channel integrated oxidation ditch had good effect on treating high concentration city waste water.Based on a great deal of tests, and through analysis of test result, experience on taming activated sludge was accumulated, operating parameters of integrated oxidation ditch which were best suitable for local condition were acquired. It was found that under the situation without solitude anaerobic zone, when the apparent anaerobic zone was absent, the strengthen biological phosphor removal phenomenon was really exist, and the phosphor removal efficiency was increasing with the increasing of BOD5/TP, F/M. It was found through the test that the side channel in this technology had strong solid liquid separating effect, together with good shock resistance.In this paper, based on analysis of waste water treatment theory, through a .great deal of pertinence tests, first hand information and practical experience were provided for operating management of side channel integrated oxidation ditch.In this paper, based on in-depth analysis of solid liquid separating mechanism, research was done for solid liquid separating effect and influential factor of side channel. Based on in-depth analysis of sludge returning and floating mechanism, a method with pump suction and laminar flow equipment forreducing of sludge floating was provided.
