Problems solved by technology

However, during the use of the ozone catalyst prepared by this method, the active components are easily affected by the water quality and fall off on the one hand, and on the other hand, the catalyst will collide and fall off due to processes such as air washing and backwashing, and the catalyst will lose its catalytic activity. , the service life of the catalyst is short, and the catalyst is easily poisoned; the preparation procedure of the ozone catalyst is relatively complicated, there is a problem of uneven loading in large-scale preparation, and the cost of catalyst preparation is also high

Embodiment 1

[0038] refer to figure 1 , 3 , 4, and 5, the present embodiment provides a non-loaded ozone catalytic oxidation treatment sewage system, including a water inlet unit 1, the water inlet unit 1 is connected to the bottom of the non-loaded ozone catalytic oxidation unit 7, and the non-loaded ozone catalytic oxidation unit 7 The top of the catalytic oxidation unit 7 is connected with an exhaust gas treatment unit 16, the upper part of the side wall of the non-loaded ozone catalytic oxidation unit 7 is connected with a water outlet unit 14, and the top of the water outlet unit 14 is connected with the tail gas treatment unit 16, and the side wall of the non-loaded ozone catalytic oxidation unit 7 A water outlet circulation unit is connected, the inlet end of the water outlet circulation unit communicates with the upper part of the side wall of the non-loaded ozone catalytic oxidation unit 7, the outlet end of the water outlet circulation unit communicates with the lower part of the...

Embodiment 2

[0053] refer to figure 2 As shown, the difference between the sewage treatment system of this embodiment and Embodiment 1 is that the water in the water inlet pool of the water inlet unit 1 is obtained by sedimentation, and the water outlet end of the water inlet pump 3 is connected with a filter unit through the water inlet pump outlet pipe 4 5, the outlet end of the filter unit 5 communicates with the bottom of the non-load type ozone catalytic oxidation unit 7 water distribution and gas distribution area 7-1 through the filter unit outlet pipe 6, and the water inlet pump 3 pumps the sewage in the water inlet unit 1 into the To the filter unit 5, and then enter the non-supported ozone catalytic oxidation unit 7, by setting the filter unit 5 to remove the colloids and suspended solids that may be carried in the incoming water, so as to avoid the non-supported ozone catalytic oxidation unit 7 from clogging.

Abstract

The invention relates to the technical field of sewage treatment, and in particular, relates to a non-supported catalytic ozonation sewage treatment system and method. The non-supported catalytic ozonation sewage treatment system comprises a water inlet unit; the water inlet unit is communicated with the bottom of a non-supported catalytic ozonation unit, and the top of the non-supported catalytic ozonation unit is communicated with a tail gas treatment unit; the upper portion of the side wall of the non-supported type catalytic ozonation unit is communicated with a water outlet unit, the top of the water outlet unit is communicated with the tail gas treatment unit, the side wall of the non-supported type catalytic ozonation unit is communicated with a water outlet circulation unit, and the inlet end of the water outlet circulation unit is communicated with the upper portion of the side wall of the non-supported type catalytic ozonation unit; and the outlet end of the water outlet circulation unit is communicated with the lower part of the side wall of the non-supported catalytic ozonation unit, and the communicated part of the water outlet unit and the non-supported catalytic ozonation unit is higher than the inlet end of the water outlet circulation unit. The system is simple and convenient to use, and can be used for catalytic ozonation advanced treatment of various types of sewage.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a non-supporting ozone catalytic oxidation treatment sewage system and a method thereof. Background technique [0002] With the increasingly stringent domestic environmental protection policies, the sewage discharge standards are becoming increasingly stringent. Upgrading and upgrading of sewage plants, and near-zero and zero discharge of industrial wastewater have become the development trend of the sewage treatment industry. Removal of refractory organic matter is the main problem faced by sewage plant upgrading and upgrading, industrial wastewater near-zero and zero discharge. [0003] At present, the most commonly used and cost-effective removal method for refractory organic matter in sewage is mainly advanced oxidation method. Advanced Oxidation is a method that uses the strong oxidation of hydroxyl radicals to remove refractory organic matter in sewage. Hydroxyl ...
