Tower type sewage purification device based on spiral structure

Abstract

The invention discloses a tower type sewage purification device based on a spiral structure. The tower type sewage purification device comprises a tower body, wherein the tower body is of a cylindrical structure with an upper-end opening; a central shaft is arranged in the tower body; a spiral blade is arranged on an outer wall of the central shaft; the inner part of the tower body is separated into a spiral channel through the blade and the central shaft; a top cover is arranged at the upper end of the tower body and a water inlet is arranged on the top cover; a water outlet is arranged at the bottom of the tower body; separation plates are uniformly arranged on the blade; each separation plate is of a groove body structure with a U-shaped end face and is formed by bending a stainless steel wire net; an opening of each separation plate is connected with the upper surface of the blade and two ends of each separation plate are connected with an inner wall and the central shaft of the tower body; filler is filled into the separation plates; a strip-shaped opening is formed in the position, corresponding to a connection part of the separation plates and the tower body, of the outer wall of the tower body; and a filling door capable of being opened and closed is arranged at the outer side of the strip-shaped opening. By adopting the tower type sewage purification device based on the spiral structure, a sewage treatment process can be accelerated and the filler is convenient to clean and replace.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, in particular to a tower-type sewage purification device based on a spiral structure. Background technique [0002] Micro-electrolysis technology is currently an ideal process for treating high-concentration organic wastewater, also known as internal electrolysis. It uses the micro-electrolytic material filled in the wastewater to generate a 1.2V potential difference to electrolyze the wastewater to achieve the purpose of degrading organic pollutants without electricity. The micro-electrolysis materials used in micro-electrolysis technology, that is, fillers, are mostly charcoal particles and iron particles. The existing sewage purification devices for micro-electrolysis technology have low purification efficiency due to the small contact area between sewage per unit volume and fillers. Simultaneously because most of the prior art is that filler is directly put into se...

Problems solved by technology

The micro-electrolysis materials used in micro-electrolysis technology, that is, fillers, are mostly charcoal particles and iron particles. The existing sewage purification devices for micro-electrolysis technology have low purification efficiency due to the small contact area between sewage per unit volume and fillers. At the same time, since most of the existing technologies put the filler directly into the sewage tank for reaction, the filler is not easy to replace and clean up.
