Embodiment

[0017] Example: see figure 1 , the Carrousel oxidation ditch of the present invention is similar to the U-shaped Carrousel oxidation ditch 1 that is opened and deformed. An anoxic ditch 2 of the same length is arranged side by side in the middle of the U-shaped, and there is an anoxic ditch with a longitudinal partition wall 11 at the horizontal end. Oxygen ditch3. The U-shaped Carrousel oxidation ditch and the anoxic ditch are respectively provided with a number of rotary disc aeration devices 6 . There is a vertically inclined partition wall 5 between the two aeration devices in the anoxic ditch to form a variable-speed circulating flow. Each ditch is built with an underwater pushing flow device 7 . The anoxic ditch, the anaerobic ditch, and the aerobic ditch are adjacent to the space 4, forming a nitrification liquid recirculation zone, and the recirculation zone and the aerobic ditch have an overflow port 10 with a controllable gate. A nitrification liquid reflux pump ...

Abstract

The invention relates to an improved A<2> / C Carrousel oxidation ditch which is characterized in that oxygen-poor ditches are internally positioned in the middle of a Carrousel aerobic ditch, and an aerating device is arranged; anaerobic ditches are arranged at the transverse ends of the carrousel aerobic ditch and the oxygen-poor ditches, wherein the anaerobic ditch is a circulating ditch internally provided with a longitudinal separation wall; and an overflowing port which can be opened or closed is arranged between the anaerobic ditch and the aerobic ditch. By adopting the unique ditch-typecombination, the improved carrousel oxidation ditch can achieve the aim of flexibly changing and regulating a treatment process by controlling and opening different overflowing ports according to inflow amount and different pollutant indexes, and greatly improve the flexible operation function of the carrousel oxidation ditch. The ditch-type combination also effectively reduces structural dead spaces and process dead spaces after combination, and meanwhile, the ditch-type combination spaces form a nitration liquid refluxing area, thereby the treatment amount can be also increased. A part of aerating devices of a plurality of single low-power aerating devices provided with rotating discs, rotating bushes, rotating dishes, impellent flows, and the like can be flexibly powered on or off according to treatment situations, thereby the power consumption is less.

Description

technical field [0001] The present invention is for A 2 / C The improvement of Carrousel oxidation ditch, especially involving a combined pool type with less dead zone and better mixing effect in the anaerobic section. Background technique [0002] A 2 / C Carrousel (Carrousel) oxidation ditch ( figure 2 ), which is an improvement to the standard Carrousel oxidation ditch, by adding an anaerobic ditch 3 and anoxic ditch 2 arranged horizontally and side by side at the front of the water intake, so as to improve the nitrogen and phosphorus removal capacity of the treatment. However, in this combined ditch type, the anaerobic ditch is not adjacently connected to the Carrousel aerobic oxidation ditch 1, and is separated by an anoxic ditch in the middle, so the treatment process can only be fixed anaerobic-anoxic-aerobic The model cannot flexibly change the treatment process according to the changes in the quality and quantity of the treated water, resulting in either an increas...
