Abstract

The invention relates to a large-capacity microwave-photocatalytic wastewater degradation device combined with the function of coulomb repulsion force, and belongs to the technical field of wastewater treatment. In order to completely solve the problems in the relevant prior art that the contact agent is weak in the intercept link; a small amount of wastewater can be treated by using a reactor with a single tank; the moment at the end of a degradation reaction is difficult to distinguish; a contact agent agglomeration matter cannot be forcedly dissipated in situ; the agglomeration of the contact agent is not perceived in time; the charged characteristic of contact agent particles is not utilized well and the like, the large-capacity microwave-photocatalytic wastewater degradation device is provided. According to the structure of the device, a microwave irradiation airspace is limited; the capacity of the reactor can be expanded substantially; bubble flows are led to be released to a key reaction area; a hollow fiber membrane changed with negative electricity is utilized to strengthen the interception of the contact agent; the contact agent agglomeration matter can be forcedly dissipated in situ as well as a quartz tube is ultrasonically cleaned at the same time; relevant power supplies are automatically closed at the end of the degradation reaction; and the main inducement parameter of the contact agent agglomeration is automatically detected as well as an automatic alarm is given.

Description

technical field [0001] The invention relates to a large-capacity microwave photocatalytic waste water degradation device integrated with Coulomb repulsion, and belongs to the technical field of CO2F waste water 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 particles inside the liquid. The electrodeless ultraviolet lamp is covered and protected by a quart...
