Efficient energy-saving and environment-friendly sewage treatment equipment

Abstract

The invention discloses efficient energy-saving and environment-friendly sewage treatment equipment. The efficient energy-saving and environment-friendly sewage treatment equipment comprises a treatment casing, wherein a separating board is fixedly connected to the inner part of the treatment casing; a first rotating shaft is arranged inside the treatment casing above the separating board and is vertically arranged; the top end of the first rotating shaft upwards extends; the top end of the first rotating shaft is fixedly connected with a first motor output shaft located on the upper side of the treatment casing; a plurality of disturbance plates are fixedly connected onto the first rotating shaft; and a plurality of disturbance holes are uniformly formed in the disturbance plates. The efficient energy-saving and environment-friendly sewage treatment equipment disclosed by the invention has the beneficial effects that sewage and a flocculating agent are disturbed by the disturbance holes in the disturbance plates, so that the sewage and the flocculating agent can be sufficiently mixed, and the flocculation effect is improved; and after flocculation is ended, a separating device is descended by using a height adjusting device, a second separating board matched with a threaded rod moves leftwards, first through holes are enabled to be staggered with second through holes, and the sewage is separated from flocculates by the separating device, so that separation is realized.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-efficiency, energy-saving and environment-friendly sewage treatment equipment. Background technique [0002] In recent years, the discharge of industrial sewage and domestic sewage in my country has been increasing year by year. The direct discharge of untreated or improperly treated sewage into nature has seriously affected environmental sanitation and threatened people's drinking water safety. Therefore, the treatment of sewage is imminent. Sewage treatment (sewage treatment, wastewater treatment): The process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and is increasingly entering the daily lives of ordina...

Problems solved by technology

Common flocculants are generally in powder or granular form, and they are directly put into the sewage, causing insoluble phenomena and reducing the flocculation effect

[0004] In the prior art, stirring blades are generally used to stir the sewage in the flocculation tank. At that time, the position of the stirring blades was only limited to the same position, and it was difficult to mix the sewage and the flocculant well, resulting in flocculation. The effect is poor; in addition, the sewage will form stratification after flocculation, that is, the flocs are on the lower side, and the sewage is on the upper side, but they cannot be separated and treated well
