Capacity expansion method of photo-catalytic wastewater biodegradation reactor for carefully recovering catalyst particles

Abstract

The invention relates to a capacity expansion method of a photo-catalytic wastewater biodegradation reactor for carefully recovering catalyst particles, belonging to the technical field of wastewater treatment. In the conventional related technology, problems such as catalyst loss, small treatment capacity of wastewater of a single tank of the reactor, undistinguishable degradation end point, lack of a real-time monitoring step for a functional state of an electrodeless lamp, lack of a water inrush preventive measure of a quartz cavity and improper utilization of catalyst charge characteristics exist, and the scheme aims at the series of problems. The scheme comprises the following main steps: closing up a microwave radiation range by a metal cage; bunching a rising bubble flow by a microphone-shaped member; expanding the size of the reactor; finely intercepting micro-scale and nano-scale catalyst particles and collision fragments thereof by using a filter internally comprising a negative charged filter membrane; monitoring a reaction process by using an ozone sensor and automatically controlling a related power switching mechanism by using a sensing electric signal; self-checking an agglomeration main incentive parameter; probing the functional state of the electrodeless lamp in the reactor by using an optical fiber, thereby preventing failure of an electrodeless ultraviolet radiation source system.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a photocatalytic wastewater degradation reactor for meticulously recovering catalyst particles, 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 pro...
