The first water level detector can feed back the water level situation to the system, so as to control whether the eleventh control valve 511 needs to be opened. When the first water quality detector 720 is set, when the first water quality detector 720 detects that the concentrated water in the concentrated water storage container 700 reaches or exceeds the set value, that is, the concentrated water cannot be used by the system, the drain pump 740 and The twelfth control valve 512 is discharged, or fed back to the system so that the eleventh control valve 511 remains closed.

In some embodiments of the present invention, the concentrated water storage container 700 is provided with a first water quality detector 720, the first branch 301 is provided with a second water quality detector 310, and the pure water end 420 is provided with a third water quality detector In the detector 320, the sixth branch 306 connecting the concentrated water end 430 and the concentrated water storage container 700 is provided with a frequency conversion valve 330, and the frequency conversion valve 330 is based on the detection value of the second water quality detector 310 and the third water quality detector 320. To control the water flow of the sixth branch 306 . Specifically, at the beginning and during the normal water production mode, the third water quality detector 320 detects the quality of pure water, and multiplies the data of the purified water quality detected by the second water quality detector 310 by 10% to set the reference value. This value is set according to each region. , and the national standard changes. When the data value of pure water detected by the third water quality detector 320 is less than the reference value, the frequency conversion valve 330 gradually reduces the release of the concentrated water flow until the third water quality detector 320 detects the pure water quality, which is slightly less than or Stable concentrated water flow release when equal to the reference value. When the third water quality detector 320 detects that the pure water data value is greater than the reference value, the frequency conversion valve 330 gradually increases the flow of concentrated water by frequency conversion, until the third water quality detector 320 detects the pure water quality, and is stable when it is slightly less than or equal to the reference value Concentrated water flow release. When the third water quality detector 320 detects the pure water quality data, when the data is less than the reference value, when the concentrated water flow rate of the variable frequency valve 330 is released to the minimum value, and when the data is still less than the reference value, (the first variable frequency pump 611 increases the water pressure, increases the The clean water flow is output, but the water pressure should not be higher than the optimal peak pressure of the reverse osmosis membrane design flow in the post-filter system, and the first pressure detection mechanism 612 detects the water pressure in real time. When the data is greater than the reference value, the frequency conversion valve 330 concentrates the water flow When the data is released to the maximum value, when the data is still greater than the reference value, the first variable frequency pump 611 reduces the water pressure and reduces the output of purified water flow, until the data is slightly less than or equal to the reference value, the first variable frequency pump 611 stabilizes the water pressure and maintains this state. Lower clean water flow output.

The system also has a mixed reuse water production mode, that is, when the normal water production mode is activated, the first pressure detection mechanism 612 detects the water pressure, and when the pipeline water pressure meets or is lower than the design value of the corresponding mode, the first variable frequency pump 611 starts to the corresponding gear, pressurizes the pipeline water pressure and inhales the water from the sealed concentrated water storage container. At the same time, the second water quality detector 310 collects purified water quality data, and the eleventh control is turned on, and the purified water generated by the ultrafiltration membrane filter element 100 passes through the first branch 301 and the concentrated water sucked from the concentrated water storage tank merges through the fifth branch 305 The third branch 303 flows into the reverse osmosis filter element 400 through the second branch 302 to generate concentrated water and pure water. The concentrated water flows into the concentrated water storage container through the sixth branch 306 . In the beginning and process of water production in this mode, the third water quality detector 320 detects the pure water quality, and multiplies the purified water quality data detected by the second water quality detector 310 by 10% to set the reference value. This value is based on various regional and national standards. When the third water quality detector 320 detects that the pure water data value is less than the reference value, the frequency conversion valve 330 keeps the initial set concentrated water flow release value unchanged in this water production mode. When the third water quality detector 320 detects that the pure water data value is greater than the reference value, the frequency conversion valve 330 gradually increases the flow of concentrated water and releases the concentrated water until the third water quality detector 320 detects the pure water quality, and stabilizes the concentrated water when it is slightly less than the reference value Traffic release. When the data is greater than the reference value, when the concentrated water flow of the variable frequency valve 330 is released to the maximum value, and the data is still greater than the reference value, the first variable frequency pump 611 reduces the water pressure and reduces the output of the mixed water flow until the data is slightly less than the reference value, the first variable frequency pump 611 A variable frequency pump 611 stabilizes the water pressure and keeps the mixed water flow output in this state.

When the system detects that the reverse osmosis filter element 400 reaches the flushing condition, the first pressure detection mechanism 612 detects the water pressure in the pipeline. When the water pressure in the pipeline meets or is lower than the design value of the corresponding flushing mode, the first variable frequency pump 611 does not start or starts to Corresponding gear, pressurize the pipeline water pressure. Each control valve is opened and closed according to the normal water production mode, and the frequency conversion valve 330 is fully opened. The purified water enters the reverse osmosis filter element 400 through the second branch 302, and the water flow forms a shear force on the surface of the membrane, washes away the inorganic pollutants deposited on the surface of the membrane and deposits insoluble salts, and flows through the sixth branch 306. Water storage container 700 . Multiple flushing modes are used for each flushing cycle, and different modes use different pipeline water pressures and flushing times.

When the user needs to use pure water, the thirteenth control valve 513 can be opened directly, and the third pressure booster Under the action of 830, the pure water in the pure water storage container 800 is taken, and the process of taking pure water will not conflict with the current operation mode of the system, and the water taking is very convenient. At the same time, the second water level detector group 810 is used to detect the water level in the pure water storage container 800 in real time, so as to feed back the water level information to the system, so that the system enters the water production mode or other modes. The third pressurizing device 830 can use a water pump or a variable frequency water pump
