Description

TECHNICAL FIELD

[0001] The utility model relates to the field of reaction tank for sewage treatment engineering, specifically to a reaction tank for sewage treatment engineering. BACKGROUND

[0002] The reaction tank for sewage treatment engineering is a key equipment for realizing the core functions of biological degradation, nitrogen and phosphorus removal of sewage, and directly affects the treatment efficiency and energy consumption. The traditional reaction tank (such as A / O and oxidation ditch) relies on plug flow or complete mixing mode, and has defects such as uneven flow state, serious short flow and low sludge separation efficiency. Typical applications include municipal sewage treatment, industrial wastewater advanced treatment and other scenes, and provide technical support for sewage resource utilization.

[0003] As disclosed in the authorized announcement No. CN221971415U, a reaction tank for sewage treatment engineering is disclosed, which relates to the technical field of sewage treatment engineering. The reaction tank includes a water inlet tank and a reaction tank body. The water inlet tank is arranged on one side of the reaction tank body. A sieve plate is arranged inside the water inlet tank. A scraping plate is arranged inside the reaction tank body. The scraping plate agitates the sludge and impurities at the bottom of the reaction tank body to prevent them from adhering to the bottom of the reaction tank body for a long time. At the same time, the scraping plate can fully contact the sludge with microorganisms and sewage, improving the biological degradation efficiency of the reaction tank. The sieve plate inside the water inlet tank can preliminarily treat the sewage and remove the impurities inside the sewage that are difficult to be biodegraded. The inclined plate inside the sedimentation tank can make the sludge stop when it encounters resistance, so that the sludge can be fully precipitated inside the sedimentation tank, and the sludge and microorganisms can be separated to prevent the loss of microorganisms in the sludge. However, the reaction efficiency of the reaction tank is still low during use. Therefore, we propose a reaction tank for sewage treatment engineering to solve the problem of low reaction efficiency of the traditional reaction tank. SUMMARY
