Description

TECHNICAL FIELD

[0001] The utility model relates to sewage treatment equipment technical field, concretely is a multistage AO process sewage treatment equipment. BACKGROUND

[0002] The multistage AO process sewage treatment equipment realizes the efficient removal of nitrogen and phosphorus in sewage through the multistage anoxic and aerobic alternate treatment of the biological reaction tank. In the anoxic tank, denitrifying bacteria play a role, and through the denitrification process, nitrate in the sewage is reduced to nitrogen, significantly reducing the concentration of nitrate, thereby achieving effective denitrification effect. In the aerobic tank, phosphorus-accumulating bacteria absorb phosphorus in the sewage to achieve the goal of removing phosphorus. At the same time, active aerobic microorganisms degrade organic matter in the sewage under an oxygenated environment, converting complex organic matter into harmless metabolic products, significantly reducing the BOD and COD concentrations in the sewage, and ultimately improving water quality, so that the effluent water quality meets the national discharge standards, providing protection for water environment.

[0003] The patent with publication number CN222293807U discloses a multistage AO process sewage treatment equipment, which includes a shell, an anaerobic zone, an anoxic zone and an aerobic zone are arranged in the shell, an air pump is fixedly connected to the outer wall of the aerobic zone, an air inlet pipe is fixedly connected to the output end of the air pump, a fixing mechanism for fixing the air inlet pipe is fixedly connected to the inner wall of the aerobic zone, a rotating assembly is fixedly connected to the inner wall of the aerobic zone, an aeration disc is fixedly connected to the rotating assembly, and a connecting assembly is arranged between the air inlet pipe and the aeration disc. The utility model discloses a kind of aeration discs, one group is damaged, and another group can continue to work, which can guarantee that the aerobic zone is normally aerated, and at the same time, when the multistage AO process sewage treatment equipment is cleaned, the aeration disc can be lifted up to prevent the staff from tripping over the pipe network of the aeration disc, and the possibility of the aeration head being stepped on is avoided, which is simple and convenient to operate.

[0004] Although the prior art can lift the aeration disc when cleaning the aerobic zone to prevent the staff from tripping over the pipe network of the aeration disc and effectively reduce the risk of the aeration head being stepped on, the staff still needs to manually separate the nut from the threaded pipe before rotating the aeration disc, which is tedious, and after cleaning is completed, the staff must tighten the nut and the threaded pipe again. If not careful, the above operation process can easily cause impurities and dirt to enter the threaded pipe, causing the aeration head to be blocked, which will directly affect the aeration airflow of the aerobic zone, and thus cause the water flow to be turbulent, affecting the overall sewage treatment effect. In view of this, we propose a multistage AO process sewage treatment equipment. SUMMARY
