Acoustic wave vibrations stick is made of supersonic generator and ultrasonic wave shake head, and the supersonic generator is located at top plate top.
7. a kind of ultrasonic wave as described in claim 1 and ultraviolet advanced oxidation couple water purification system, which is characterized in that the purple
Lamp tube joint is installed between outer smooth lamp group and top plate, is connected through a screw thread between the lamp tube joint and ultraviolet light lamp group.
8. a kind of ultrasonic wave as described in claim 1 and ultraviolet advanced oxidation couple water purification system, which is characterized in that the control
System is provided centrally with display and button.
9. using the method for ultrasonic wave as described in claim 1 and the coupling water purification system water purification of ultraviolet advanced oxidation, feature
It is, steps are as follows:
Step 1 will need the raw water purified to be placed in water tank inlet, and free radical donor is placed in pharmacy jar；
Step 2, raw water are pressurizeed through centrifugal pump, are adjusted flow by gate valve and flowmeter, are then flowed into static pipeline mixer, from
Static pipeline mixer is imported after metering pump pressurizes by base donor；
Raw water and free radical donor are uniformly mixed by step 3, static pipeline mixer, and mixed liquor is then delivered to first order reaction
Device opens ultrasonic generator and ultraviolet light lamp group, and the target organic in raw water is in free matrix, ultrasonic wave and ultraviolet light
It is cleaved under double action；
Step 4 flows into second reactor through first-stage reactor treated water, opens ultrasonic generator and ultraviolet light lamp group,
Continue to react；
Step 5, the solution after aoxidizing twice flow out to out water tank, and reaction is completed.
