When water sample central processing unit 28 passes through after to former water analysis detection, after sending working parameter regulation and control instruction to current temperature setter 27, the instruction output end 13 of water sample central processing unit 28 also sends working parameter regulation and control instruction to the information input terminal 14 of ultrasonic wave setter 29 simultaneously; The output terminal 15,16,17,18 of ultrasonic wave setter 29 sends work order to the ultrasonic transducer in the container 21 being assemblied in anti-penetration wastewater disposal device 20 and horn 33,39; Ultrasonic wave operating mode is: 40S is a loop cycle, and ultrasonic time 20S is 20S without ultrasonic time, until reverse osmosis operation terminates; Supersonic transducer frequency is 40kHz, and output rating is 40w.
After water sample central processing unit 28 passes through to detect analyzing and testing to former water, to current temperature setter 27, when ultrasonic wave setter 29 sends working parameter instruction, after the water pressure information input terminal 12 of water sample central processing unit 28 receives water pressure sensor 34 information be assemblied in the container 21 of anti-penetration wastewater disposal device 20, the instruction output end 8 of water sample central processing unit 28 also sends the instruction of regulation and control working parameter to the instruction of pulsating high-pressure water inlet device 19 input section 26 simultaneously, the output ripple timed interval of further regulation and control high-pressure pump, former water enters flow velocity and the flow of reverse-osmosis treated device 20, with the operating pressure on reverse osmosis membrane in the container 21 reaching regulation and control anti-penetration wastewater disposal device 20.Because pulsating high-pressure water inlet device and hyperacoustic synergy create strong fluctuating flow and turbulence effect, effectively can delay the scale formation of reverse osmosis membrane, improve the working efficiency of system.
In system operation, the part output fresh water 43 of anti-penetration wastewater disposal device 20 feeds back to the output fresh water information input terminal 11 of water sample central processing unit 28, this time operation output fresh water standards parameter is contrasted through water sample central processing unit 28, the instruction of regulation and control working parameter is sent further to current temperature setter 27, ultrasonic wave setter 29 and pulsating high-pressure water inlet device 19, until the production water specific conductivity of this time operation drops to 800 micro-Siemens/cm, guarantee that output fresh water reaches country and quotes water quality standard GB5749-2006.Output fresh water 48 is exported by pipeline, and the recyclable reprocessing of the dense water of part 49 utilizes.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, can also make a lot of form, these all belong within protection of the present invention.
