Waste water light degradation reactor expansion method for preventing ozone from flowing into magnetron

Abstract

The invention relates to a waste water light degradation reactor expansion method for preventing ozone from flowing into a magnetron, belonging to the technical field of waste water treatment. Problems such as weaker catalyst interception link, lower single-tank treatment capacity of a reactor, difficulty in distinguishing a degradation reaction endpoint moment, incapability of powerfully dissipating catalyst clusters in situ and detecting catalyst agglomeration in time and magnetron corrosion caused by reverse crossflow of secondary ozone exist in the traditional relevant technologies, and the scheme aims to solve the series of problems. The waste water light degradation reactor expansion method mainly comprises the following steps of: limiting a microwave irradiation region; intercepting a catalyst stage by stage by using a multi-stage cascade filter; dissipating the catalyst clusters in situ by using low-frequency ultrasonic waves from the bottom of the reactor, and meanwhile, cleaning a quartz tube; perceiving the reaction progress by using an ozone sensor, and automatically turning off relevant power sources when a degradation end point is reached; actively warning the catalyst agglomeration trend; and separating a waveguide tube by using a wave-transparent airtight partition plate to block a reverse crossflow channel of gas containing ozone on the premise that the microwave transparence is not interfered basically.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a wastewater photodegradation reactor to prevent ozone from entering a magnetron, and belongs to the technical field of CO2F wastewater treatment. Background technique [0002] Microwave photocatalytic degradation treatment technology, as an effective harmless treatment technology for industrial wastewater containing organic pollutants, has attracted much attention in recent years. [0003] Regarding the microwave photocatalytic degradation technology, as an example, refer to the Chinese patent application with publication number CN102260003A. [0004] The Chinese patent application with the publication number CN102260003A uses microwaves as the excitation source to excite the electrodeless ultraviolet lamp to emit ultraviolet rays, and irradiates the suspension mixed with photocatalyst titanium dioxide inside the liquid. The electrodeless ultraviolet lamp is shrouded and protected by a qu...

Problems solved by technology

[0048] Based on the structure of the CN102260003A scheme, during its operation, the air pumped into the quartz tube cavity will be irradiated by ultraviolet rays, part of which will be converted into ozone, and most of the ozone-containing air formed in this way will be sent to the micropore aeration by pressure However, we know that the structure of the magnetron itself is not vacuum-tight, and the connection between the waveguide and the magnetron is generally not vacuum-tight, so all the relatively positive pressure A small part of the above-mentioned ozone-containing air will inevitably flow into the structural area where the magnetron is located, and the structural component materials of the magnetron, including its shell material, generally do not have the ability to resist ozone corrosion. Then, such a In the future, the ozone-containing air that enters the magnetron structure area in the reverse direction will inevitably form a corrosion effect on the magnetron components. The power of this corrosion effect may be difficult to detect in a short period of time on the laboratory scale. However, it will definitely appear after a little longer time. , the problem of reverse flow of ozone-containing air and corrosion of magnetron components cannot be avoided, this is the fifteenth problem
