Building construction sewage treatment and sedimentation device capable of automatically proportioning fed catalyst and treatment method

Abstract

The invention relates to the technical field of building sewage sedimentation treatment, in particular to a building construction sewage treatment and sedimentation device capable of automatically proportioning a fed catalyst and a treatment method. The building construction sewage treatment and sedimentation device comprises a sedimentation tank, the sedimentation tank is connected with a proportioning box through a communicating pipe, and a filter screen for filtering and sedimentation is arranged in the sedimentation tank; and the lower end of the proportioning box is extruded and fixed at the upper end of the sedimentation tank through a buffer spring, the upper end of the proportioning box is covered with a cover plate in a sealing manner, the upper end of the cover plate is provided with a plurality of groups of fixed pipes which are distributed in a circumferential array manner, and the fixed pipes are internally provided with lifting inner pipes of which the lifting is controlled by a hydraulic cylinder. The device has the beneficial effects that the fixed pipes are matched with the lifting inner pipes, therefore, feeding is achieved through an inclined flow channel, raising of dust is avoided, meanwhile, a bottom plate which is eccentrically and rotationally installed is matched with the hydraulic cylinder in a lifting mode, extrusion discharging of rolling wheels on the rotating bottom plate is achieved, and powder backflow caused in the feeding process is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of construction sewage sedimentation treatment, in particular to a construction sewage treatment sedimentation device and a treatment method with automatic rationing of catalyst input. Background technique [0002] A large amount of wastewater will be generated during the construction process. In order to reduce the pollution to the environment, the wastewater usually needs to be treated by sedimentation to meet the discharge standard. However, in order to improve the efficiency of sedimentation, it is necessary to add a quantitative ratio of catalyst to the sedimentation tank. . [0003] In the actual feeding process, because there are many types of catalysts, the components are complex and most of them are powdery structures, it is easy to cause dust and pharmaceuticals to rise during feeding, which will cause aspiration and affect health. At the same time, it is necessary to seal during the mixing process...

Problems solved by technology

[0003] In the actual feeding process, because there are many types of catalysts, the components are complex and most of them are powdery structures, it is easy to cause dust and pharmaceuticals to rise during feeding, which will cause aspiration and affect health. At the same time, it is necessary to seal during the mixing process. , to avoid dust pollution to the environment, while the existing feeding device lacks an automatic sealing device after feeding

[0004] To this end, a building construction sewage treatment sedimentation device and treatment method with automatic proportioning of catalyst feeding is provided to solve the safety problem of catalyst feeding in the sedimentation process
