Embodiment 2

[0037] Use this device to process rhodamine B solution, the steps are as follows:

[0038] Step 1, make up the solution

[0039] Accurately weigh 20 mg of rhodamine B, dissolve it in ultrapure water, and set the volume to 2000 ml to obtain a 10 mg / L rhodamine B solution;

[0040] , step 2, process with the device of the present invention

[0041] Control the flow rate of rhodamine B solution in the water inlet pipe to 50mL / min, and the water inlet time is 1min. Measure the rhodamine B solution in the ultrasonic reactor every 10min. It is found that the degradation effect of rhodamine B solution is obvious within 1 hour. see results figure 2 .

Abstract

The invention provides an ultrasonic-photocatalysis combined sewage treatment device and a treatment process thereof. The device comprises the following structure: a water inlet valve, a water inlet time-space sensor, an ultrasonic generator, a peristaltic pump, a first valve, a first flow meter, a photocatalytic membrane reactor, an ultraviolet lamp, a TiO2 catalytic membrane, a second flow meter, a second valve, a persulfate feeder, a water outlet valve and a water outlet time-space sensor; the water inlet time-space sensor and the water outlet time-space sensor are used for controlling the water inlet valve and the water outlet valve. By controlling the water inlet time-space sensor and the water outlet time-space sensor, the water outlet valve is switched off and the water inlet valve is switched on to enter the ultrasonic generator; persulfate is added into the ultrasonic generator and water is pumped into the photocatalytic membrane reactor by the peristaltic pump to be subjected to secondary stain removal; the water is repeatedly subjected to ultrasonic-assisted persulfate combined degradation treatment to obtain clean water. The device is simple and convenient to operate; the quality of the output water is good and the device has a good market prospect.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to an ultrasonic photocatalysis combined sewage treatment device and a treatment process thereof. Background technique [0002] In terms of sewage treatment, the use of ultrasound to degrade pollutants in water, especially refractory organic pollutants, has been widely used. The degradation of organic matter in the ultrasonic process is mainly through the high-temperature and high-pressure environment created by the cavitation bubble collapse process and the water Molecules act on the free radicals generated by this extreme environmental action. However, if the sewage is only subjected to ultrasonic treatment alone, the degradation rate will be slow and the energy consumption will be large. On the other hand, due to its strong oxidation and stability, persulfate can generate sulfate radical SO under the action of heat, light or catalyst. 4 · － , SO 4 · － It can effec...
