Circular convective mixing principle-based sewage treatment equipment

Abstract

The invention relates to the technical field of sewage treatment, in particular to circular convective mixing principle-based sewage treatment equipment. The equipment comprises a pool body; two mounting seats are symmetrically and fixedly connected with the outer side wall of the pool body; support columns are fixedly connected with the upper sides of the mounting seats; the top ends of the two support columns are fixedly connected with a support plate; a bearing is embedded in the middle of the support plate; the inner ring of the bearing is fixedly connected with a rotation shaft; the rotation shaft extends into the pool body; a spiral auger is arranged at the lower part of the rotation shaft; the spiral auger is sleeved by a sleeve; the bottom end of the sleeve is fixedly connected with the inner bottom of the pool body; a plurality of through holes are uniformly formed in the bottom of the sleeve. The equipment has the beneficial effects that a high-pressure pump pumps sewage intoa circular cavity through a first pipeline, and the sewage is uniformly sprayed out through a water outlet device and carries out convection in the middle of a convective device to ensure that the sewage and a flocculating agent form effective convective mixing treatment, so that the sewage flocculation effect is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment equipment based on the principle of annular convection mixing. 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 the nature has seriously affected environmental sanitation and threatened people's drinking water safety. Therefore, the treatment of sewage is imminent. 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 it is also increasingly entering the daily life of ordinary peo...

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] Chinese patent (authorized announcement is CN204607662U) is a small integrated flocculation and sedimentation equipment. In this patent, the first-level flocculant and the second-level flocculation tank are used to achieve the flocculation effect, but it is not used in the first-level flocculation tank or the second-level flocculation tank. If any mixing equipment is installed, the flocculant and sewage cannot be fully and effectively mixed, and it is difficult to achieve a better flocculation effect
