Advanced sewage treatment device

Abstract

The invention provides an advanced sewage treatment device, which comprises a shell, a filtering material, a filtering material supporting plate, a water collection tank, a water distributor, a water distributor fixing frame, a water outlet pipe, a water inlet pipe, a chemical feed pipe and a dredge pipe, wherein the filtering material is arranged in the shell; the water distributor is connected with the water inlet pipe; the water outlet pipe is arranged on the shell; the water inlet pipe is arranged at an upper opening end of the shell; the dredge pipe is arranged at the bottom of the shell; the advanced sewage treatment device is characterized in that the filtering material is arranged on the upper part in the shell and is supported by the filtering material supporting plate; an oblique plate and an oblique plate supporting frame are arranged below the filtering material; the bottom of the oblique plate is positioned on the oblique plate supporting frame; a chlorine dioxide pipe vertically and downwardly leads into and penetrates through the filtering material from the upper part of the shell; the lower end of the chlorine dioxide pipe is connected with a perforated pipe; and the perforated pipe is positioned between the oblique plate and the filtering material. According to the advanced sewage treatment device, coagulation, oblique plate sedimentation, chlorine dioxide oxidation, filtration and adsorption effects are finished in a same tank; and the advanced sewage treatment device has the advantages of rational and compact structure, good effluent quality, high treatment efficiency, low operation cost, high adaptability and easiness in operation and management.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a sewage advanced treatment device. Background technique [0002] Advanced treatment technology is a key topic in the field of water treatment for environmental protection. Water treatment technology can be divided into physical method, chemical method, physicochemical method and biological method according to its mechanism. It is difficult for a single treatment method to meet the water quality requirements of reused water. Usually, advanced treatment technology requires a combination of multiple processes, that is, to combine various water treatment methods to carry out advanced treatment of sewage. At present, the commonly used process for advanced treatment in my country is coagulation + sedimentation + filtration, which is a combination of a single treatment technology, so there are problems such as long treatment process, high operating cost, and low treatment effi...
