Background

The reaction tank is one of the commonly used treatment structures in sewage treatment, and is mainly used for mixing and reacting sewage and a medicament, and the sewage and the medicament are required to be uniformly mixed and completely reacted. The common reaction tanks are coagulation reaction tanks, flocculation reaction tanks and the like in coagulation sedimentation (air floatation), 1-5 types of added medicaments are generally added into the reaction tanks according to the requirements of the treatment process, the number of the corresponding reaction tanks is 2-6, and in order to save floor area and investment cost, common-wall combined tank structures are often adopted among the reaction tanks, between the reaction tanks and the sedimentation tank (air floatation tank). The reaction tank has more problems in design and practical application, firstly, the positions and elevations of the water through holes of the reaction tank are randomly arranged, holes are formed in a diagonal and up-down staggered manner, and the sewage has a short flow phenomenon; secondly, because of the number of the reaction tanks and the plane arrangement, holes can not be formed diagonally and vertically in a staggered manner, and the sewage has a short flow phenomenon; thirdly, when reaction tank sewage flows from bottom to top, the medicament is thrown on the water surface, even if a stirrer or air is used for stirring and mixing, part of the medicament still remains unreacted and directly flows into the next reaction tank, the sewage and the medicament are mixed unevenly, the mixing effect is poor, and fourthly, the medicament feeding pipe is directly inserted into the sewage to realize the sufficient mixing of the medicament and the sewage, but an operator can not observe whether the medicament is fed in the reaction tank, and the sewage suck-back or the medicament siphon can be caused when the design is improper. The tank capacity and the medicament are often not fully utilized in the actual operation of the reaction tank, so that the medicament is wasted, the reaction effect is poor, and the effluent quality cannot meet the process treatment requirement.
