Sewage filtering device for environmental engineering and filtering method thereof

Abstract

The invention belongs to the technical field of sewage filtering, and particularly relates to a sewage filtering device for environmental engineering and a filtering method thereof. The sewage filtering device comprises a filtering box, the front side wall of the filtering box is provided with a sewage discharging pipe communicating with the interior of the filtering box, and a sewage discharging mechanism corresponding to the sewage discharging pipe is arranged in the filtering box. A moving plate is arranged on the upper side of the filtering box, a driving mechanism for driving the moving plate to move is arranged on the filtering box, a feeding mechanism is arranged on the moving plate, a uniform stirring mechanism is further arranged on the moving plate, one end of the filtering box is connected with a purifying box, and a filtering mechanism is arranged in the purifying box. Power mechanisms used for driving the filtering mechanism to move are arranged on the side walls of the two sides of the purifying box. Through the feeding box, the moving block, a stirring paddle and an auger, a reactant for filtering is conveniently and uniformly fed, so that sewage and a reactant are mixed more uniformly, the filtering effect is improved, filtered precipitates are conveniently discharged, and the situation that subsequent sewage filtering is influenced by deposition is avoided.

Description

technical field [0001] The invention relates to the technical field of sewage filtration, in particular to a sewage filtration device for environmental engineering and a filtration method thereof. Background technique [0002] Environmental engineering has the concept of sustainable development. Environmental engineering uses scientific means to improve our living environment. A large amount of sewage exists in our lives. Environmental engineering will filter sewage in the process of treatment, and the sewage can be repeated. use to avoid waste of resources. [0003] At present, the sewage filtration devices for environmental engineering in the prior art usually need to precipitate the sewage to filter the impurities in the water. During the sedimentation process, a flocculant needs to be added. The amount is uneven, and it is not easy to mix evenly with sewage, which reduces the effect of sewage filtration. At the same time, the sewage filtration device in the prior art is...
