Sewage treatment tank and sewage treatment system

Abstract

The invention discloses a sewage treatment tank and a sewage treatment system, and the sewage treatment tank comprises a tank body having a tank cavity, wherein one side wall of the tank cavity is provided with a sundry outlet, and the bottom contour of the sundry outlet is V-shaped; filter plates which are arranged in the pool cavity and are provided with filter holes, wherein the two filter plates are downwards and obliquely arranged towards the symmetric center line, and the upper surfaces of the two filter plates are flush with the V-shaped outline at the bottom of the impurity outlet; a movable plate which is movably connected to the bottom of the filter plate and provided with a jacking column, wherein the jacking column can move along with the movable plate and is inserted into the filter hole; and a push plate which can movably push the impurities on the filter plate out of the impurity outlet. The two filter plates are used for filtering impurities, and the two filter plates incline downwards towards the middle, so that the impurities are automatically concentrated between the two filter plates, and then the push plate is used for pushing out the impurities; the movable plate moves to insert the jacking columns into the filtering holes, and after impurities in the filtering holes are jacked out, the impurities are prevented from being accumulated in the filtering holes; the water flow capacity and the sewage treatment efficiency are ensured.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment tank and a sewage treatment system. Background technique [0002] At present, sewage is produced in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. Purify sewage. [0003] In sewage treatment, the bulky substances in the sewage must be removed first to ensure the treatment effect of the sewage and the smoothness of the subsequent pipelines; usually, the bulky impurities are filtered out by grille filtration, but the traditional grille is used for a period of time Finally, some impurities may remain in the filter holes. After a long time, the water flow capacity of the grille will decrease, which will affect the efficiency of sewage treatment. Contents of the invention [0004] The present invention aims to solve at least one of the technical p...
