Device and method for comprehensively treating water body

Abstract

The invention discloses a device and a method for comprehensively treating a water body. The device for comprehensively treating the water body comprises a water inlet pipe, a pre-treater, at least one catalytic oxidation reactor and a water outlet pipe, wherein the pre-treater performs multi-stage precision filter pre-treatment on water flowing through the water inlet pipe; the catalytic oxidation reactors perform catalytic oxidation and deep purification on water which is pre-treated by using the pre-treater; and water which is treated by using the catalytic oxidation reactors is discharged through the water outlet pipe. According to the device for comprehensively treating the water body, the amount of water to be treated is controlled by adjusting the size of the pre-treater, and increasing the number and unit treatment amount of the catalytic oxidation reactors; and meanwhile, the whole device can be used in a cordwood multi-stage parallel connection mode, so that the water body with large capacity can be treated efficiently and comprehensively; and the device has a simple structure, long service life and a good comprehensive treatment effect.

Description

technical field [0001] The present invention relates to a water body comprehensive treatment device and method, in particular to a water body comprehensive treatment device and method suitable for organic waste water purification and sterilizing algae, the water body comprehensive treatment device and method can be widely used in industrial sewage, domestic sewage, Comprehensive treatment of garbage permeate, landscape water, tap water, differentiated water supply for household quarters, and drinking water for rural towns. Background technique [0002] As we all know, for sewage purification, the removal of organic matter in water and the sterilization of algae are always a technical problem in the industry, and the sterilization of algae depends largely on the use of a large number of chemicals to achieve. In the process of drinking water purification, the use of chlorine gas as an oxidant to disinfect and sterilize tap water has its fatal weakness, that is, various chlorin...

AI Technical Summary

Problems solved by technology

It is difficult to recover the catalyst of the suspension system reactor and it is difficult to apply it on a large scale. The fixed structure mostly adopts carrier coating or smearing, which has the problems of small contact surface area and low efficiency.

Japanese Patent No. 4-141294 uses porous sintered material or optical fiber as a catalyst carrier to increase the surface area, but a large part of the light cannot be irradiated, and the price is expensive and impractical

Chinese utility model patent 95244568 discloses a fixed-film photocatalytic oxidation water quality deep purifier, Chinese utility model patent 96251030 discloses a photocatalytic water quality processor, and invention patent CN1257838 discloses continuous photocatalytic purification of wastewater containing organic pollutants and A method and equipment for drinking water, the method uses a suspension system to achieve continuous treatment, but it is difficult to achieve large-capacity and efficient treatment

The water treatment equipment in the prior art has the following common disadvantages: (1) an additional stirrer is required to increase the pollution source, noise, and failure rate; (2) the reaction time is long, and it is difficult to achieve continuous treatment; (3) the catalyst carrier, It is difficult to seal the lamp protection tube and the upper and lower ends; (4) the processing capacity is small and the expansion is difficult; (5) the main consideration is to increase the overall efficiency by increasing the catalyst carrier area and improving the activity of the catalyst, which restricts the large-scale development of large capacity ; (6) Complex structure, inconvenient for installation and maintenance
