Industrial sewage treatment device

Abstract

The invention provides an industrial sewage treatment device comprising a shell, a central cylinder, a supporting filter board, a filler inside the central cylinder, a water distributor, a water collector, a water collection groove, a water outlet pipe, a water inlet pipe, a chemical feed pipe, and a sludge discharging or emptying pipe. The industrial sewage treatment device is characterized in that a stirring paddle, the water distributor and the iron carbon filler are arranged inside the central cylinder in the shell; the stirring paddle is connected with a transmission shaft of a stirring motor fixedly arranged at the top of the shell; the iron carbon filter and the bottom of the central cylinder are located on the supporting filter board; and the water inlet pipe is connected with the water distributor. One end of the water outlet pipe is connected with the water collection groove around the upper part of the central cylinder, and the other end of the water outlet pipe penetrates through the shell and is led out. The chemical feed pipe connected with the water inlet pipe is connected with equipment for adding hydrogen peroxide outside the shell. Ultraviolet lamp tubes are uniformly arranged on the circumference of the middle part of the central cylinder. The industrial sewage treatment device has the advantages that the structure is reasonable and compact, the iron-carbon micro-electrolysis technology is organically combined with a hydrogen peroxide oxidation Fenton treatment technology and an ultraviolet treatment technology, so that the good quality of outgoing water and the high efficiency can be realized.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to an industrial sewage processor. Background technique [0002] High-concentration and refractory industrial sewage has always been the difficulty and focus in the field of sewage treatment. Pollutants in sewage have high concentration and high toxicity, which have poisonous and inhibitory effects on water treatment microorganisms. Pretreatment must be carried out before biochemical treatment. In addition, due to certain Some pollutants have a stable structure and are difficult to biodegrade, and often require advanced treatment after biological treatment. At present, many technical processes are difficult to meet the standards, and although some technologies can meet the standards, the high cost of treatment makes it difficult for enterprises to accept. [0003] Hydrogen peroxide has the characteristics of product stability, safety, complete miscibility with water, no sec...

AI Technical Summary

Problems solved by technology

However, the traditional micro-electrolysis technology has problems such as easy compaction of fillers, formation of short flow or dead angle, difficulty in replacement of fillers, large amount of mud production, etc., and the treated effluent cannot meet the standard in one step, and subsequent treatment must be carried out
