The invention relates to a large-treatment-capacity photocatalytic wastewater degradation reactor associated with the charged characteristic of a contact agent, and belongs to the technical field of wastewater treatment. In order to solve the problems in the relevant prior art that the loss of the contact agent exists; the microwave energy is wasted; a single tank is rather small in capacity; 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-treatment-capacity photocatalytic wastewater degradation reactor is provided. According to the structure of the wastewater degradation reactor, a microwave irradiation airspace is limited; the capacity of the reactor can be expanded substantially; bubble flows containing ozone are enabled 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, i.e., the energy waste is avoided; the main inducement parameter of the contact agent agglomeration can be detected; and an alarm is given when the main inducement parameter exceeds the standard.
Description
technical field [0001] The invention relates to a large-capacity photocatalytic wastewater degradation reactor related to the charging characteristics of a catalyst, 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 quart...
