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 an unloaded ozone catalytic oxidation treatment system for sewage, including a water inlet unit 1, the water inlet unit 1 is connected with the bottom of an unloaded ozone catalytic oxidation unit 7, and the unloaded ozone A tail gas treatment unit 16 is communicated with the top of the catalytic oxidation unit 7, a water outlet unit 14 is communicated with the upper part of the side wall of the unloaded ozone catalytic oxidation unit 7, the top of the water outlet unit 14 is communicated with the exhaust gas treatment unit 16, and the side wall of the unloaded ozone catalytic oxidation unit 7 is connected. A water outlet circulation unit is communicated, the inlet end of the water outlet circulation unit is communicated with the upper part of the side wall of the unloaded ozone catalytic oxidation unit 7, the outlet end of the water outlet circulation unit is communicated with the lower part of the side w...

Embodiment 2

[0053] refer to figure 2 As shown, the difference between the sewage treatment system of this embodiment and the first embodiment is only 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 the filter unit through the water inlet pipe 4 of the water inlet pump. The inlet end of 5, the outlet end of the filter unit 5 is communicated with the bottom of the water distribution area 7-1 of the unloaded ozone catalytic oxidation unit 7 through the outlet pipe 6 of the filter unit, and the water inlet pump 3 pumps the sewage in the water inlet unit 1 into To the filter unit 5, and then into the unsupported ozone catalytic oxidation unit 7, by setting the filter unit 5 to remove the colloids and suspended solids that may be carried in the influent water, so as to avoid the unsupported ozone catalytic oxidation unit 7 from being blocked.

Abstract

The invention relates to the technical field of sewage treatment, in particular to a non-loaded ozone catalytic oxidation treatment sewage system and a method thereof, comprising a water inlet unit connected to the bottom of a non-loaded ozone catalytic oxidation unit, and a non-loaded ozone catalytic oxidation unit. The top of the oxidation unit is connected to the tail gas treatment unit, the upper part of the side wall of the non-loaded ozone catalytic oxidation unit is connected to the water outlet unit, the top of the water outlet unit is connected to the tail gas treatment unit, and the side wall of the non-loaded ozone catalytic oxidation unit is connected to the outlet water circulation unit, and the outlet water circulation The inlet end of the unit is connected to the upper part of the side wall of the non-loaded ozone catalytic oxidation unit, the outlet end of the outlet water circulation unit is connected to the lower part of the side wall of the non-loaded ozone catalytic oxidation unit, and the connection between the water outlet unit and the non-loaded ozone catalytic oxidation unit is high At the inlet end of the water circulation unit. The system of the invention is simple and easy to use, and can be used for advanced treatment of various sewage by ozone catalytic oxidation.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a non-loaded ozone catalytic oxidation treatment sewage system and a method thereof. Background technique [0002] With the increasingly stringent domestic environmental protection policies, sewage discharge standards have become increasingly stringent. The upgrading of sewage plants and the 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 treatment plant upgrading and renovation, near-zero and zero-discharge of industrial wastewater. [0003] At present, the most commonly used and cost-effective method for the removal of refractory organic matter in sewage is mainly advanced oxidation. Advanced oxidation is a method of removing refractory organic compounds in sewage by using the strong oxidation of hydroxyl radicals. Hydroxy...
