Microwave synergetic photocatalytic wastewater degradation reactor with more thorough utilization of oxidizing power of ozone

Abstract

The invention relates to a microwave synergetic photocatalytic wastewater degradation reactor with more thorough utilization of oxidizing power of ozone, and belongs to the technical field of wastewater treatment. In existing associated technologies, problems that the intercepting link of a catalyst is weak, the single tank treatment amount of a reactor is small, the repeated operation frequency is high, the circulating strength of inner liquid is insufficient, ozone is incompletely utilized, the endpoint of degradation reaction is hard to distinguish and the like exist. The scheme aims to solve the above problems. The reactor is isolated in structure and the microwave irradiation area is limited. The structure co-bunches a rising ozone containing bubble flow and guides the flow to the degradation reaction area. Catalyst particles are precisely intercepted by an external cascaded three-level backflush filter. The filter core of the structure is not limited in material selection. An ozone sensor is further installed at a tail gas discharge port in the structure to transmit electric signals output to a power supply controller which connects a magnetron and an air pump. Energy injection can be closed when the degradation reaction arrives at the endpoint.

Description

technical field [0001] The invention relates to a microwave synergistic photocatalytic wastewater degradation reactor which utilizes ozone oxidation power more thoroughly, 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...

Problems solved by technology

[0032] The operation of the wastewater catalytic degradation reactor needs to consume energy. Therefore, the operator will definitely hope that when the wastewater degradation reaction reaches the end, it can be impartial, neither too early nor too late to stop the continuous injection into the reactor. Energy; if the time to stop injecting energy is too early, the degradation of wastewater will not be complete; and if the end of the reaction has already been reached, but still continue to inject energy into the reactor, it is undoubtedly a waste of precious energy

The structure of CN102260003A scheme as the technical background of this case can not give any instant information to the end point of waste water degradation, so, just can only rely on experience to estimate the end point of waste water degradation reaction; And rely on experience to estimate the end point of waste water degradation reaction, then It is obviously unsatisfactory; then, how to make an immediate information output that is neither advanced nor delayed for the end point of the wastewater degradation reaction, and immediately shut down the energy input to the reactor at the right moment is a technical threshold that cannot be ignored , this is the seventh question
