Capacity expansion method of photocatalysis waste water degrading reactor for maintaining membrane component by soft ultrasound

Abstract

The invention relates to a capacity expansion method of a photocatalysis waste water degrading reactor for maintaining a membrane component by soft ultrasound, and belongs to the technical field of waste water treatment. In the relevant prior art, accelerants are lost, the microwave energy is wasted, the single tank waste water treatment quantity of the reactor is rather low, the degrading terminal point is difficult to distinguish, the accelerant agglomerates cannot disappear in situ, and cannot be observed timely, and the accelerant deposition on the membrane component cannot be removed easily and the like. Aiming at the problems, the scheme is as follows: the method mainly comprises the following steps of: drawing the microwave irradiation range by a metal cage; expanding the size of the reactor; blocking the accelerants step by step by a multistage filter; dissipating the accelerant agglomerates in situ by a low-frequency ultrasonic wave emitted from the bottom of the reactor, and meanwhile cleaning the quartz tube incidentally; monitoring the reaction process by an ozone sensor, and controlling a relevant power supply switch mechanism by a sensing electric signal automatically; detecting agglomerate main inducement parameters automatically; assisting the cleaning operation of a filter membrane component and a backflush program by the high-frequency ultrasonic wave.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a photocatalytic wastewater degradation reactor by using gentle ultrasonic to maintain a membrane module, 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 covere...

Problems solved by technology

[0044] Based on the structure of the CN102260003A scheme, during its operation, the water pump that fills the reactor cavity with waste water cannot judge whether the water level inside the reactor is high or low, and the operator can only rely on experience or visual inspection to turn off the water pump that fills the waste water in time Motor, if the experience is wrong or the visual response is not timely enough, it is easy to overflow the reactor due to excessive filling of waste water, which will cause unnecessary trouble; The membrane module pumps water outward. Without knowing the water level inside the reactor, the timing of shutting down the pump can only be judged based on experience or visual inspection. This operation is obviously unreliable, and it is very easy to make mistakes due to experience or visual inspection. If the response is not timely, the water pump cannot be shut down in time, and this kind of dry pumping and idling can easily cause the motor of the water pump to burn out. This problem cannot be ignored. This is the fourteenth problem.
