The specific working process of the utility model adjustable wastewater reflux water purification system is as follows:

Tap water enters the water purification system through the tap water inlet pipe, and passes through the PPF filter 11 in turn to remove suspended particles and iron filings in the water; passes through the UDF filter 12 to remove odors, free chlorine and macromolecular organic pollutants in the water, and passes through the CTO The filter 13 removes carcinogens such as color, odor, heavy metals, and trihalomethanes in the water, and can strongly inhibit bacterial reproduction; then the filtered water is pumped into the reverse osmosis device 4 through the booster pump 2, which can effectively remove dissolved salts in the water , colloids, microorganisms and organic matter and other substances, the concentrated water filtered by the reverse osmosis equipment 4 returns to the water inlet pipeline through the return water pipeline 8 for repeated filtration. After the clean water filtered by the reverse osmosis equipment 4 is sterilized by the ultraviolet lamp 52, it enters the activated carbon filter 6 to effectively absorb the residual colloid, organic matter, residual chlorine and peculiar smell in the water to complete the purification of the tap water, and use it directly at the water point.

The TDS probe 32 monitors the total dissolved solids (TDS) in the water flowing through the first pipeline 3 at all times, and when the measured TDS content is lower than 800ppm, close the second solenoid valve 9 and control the flow valve through the control system 81, make the water flow rate in the return water pipeline 8 550mL/min, when the measured TDS content is at 800-1500ppm, the control system opens the second solenoid valve 9, and adjusts the flow rate to 70mL/min, so that a part of concentrated water does not enter the system Backflow is directly discharged through the discharge pipeline. When the measured TDS content reaches 3000-4000ppm, the control system adjusts the flow rate of the second solenoid valve 9 to 5000mL/min. At this time, all concentrated water is discharged and no longer enters the return pipeline 8.

When the tap water supply is insufficient or the water supply is stopped, the low-voltage switch 14 is activated to automatically disconnect the circuit of the entire system to prevent the system equipment from idling; , to balance the water volume and pressure in the system, at this time, the high pressure switch 72 will be automatically activated, the circuit of the entire system will be automatically disconnected, and the water treatment process will be stopped.
