Water production control method, water production control device and ultra-pure water preparation system based on electric ball valves adjustment

The invention discloses a water production control method, a water production control device and an ultra-pure water preparation system based on electric ball valves adjustment. The method comprises an initialization step, an open/close control step, a pressure difference calibration step, and a linkage adjustment step. In the initialization step, concentrated water side discharge electric ball valve and return electric ball valve unit open and close degrees at full open and full close of the concentrated water side discharge electric ball valve and return electric ball valve are detected. In the open/close control step, the open and close of the concentrated water side discharge electric ball valve and return electric ball valve are controlled according to the unit open and close degrees; real-time open and close degrees are recorded; and the real-time and unit open and close degrees are corrected according to the detection signal feedback. In the pressure difference calibration step, the pressure difference between reverse osmosis membrane water inlet side and concentrated water side when the concentrated water side of the reverse osmosis membrane reaches a target flow rate is obtained through adjusting the concentrated water side discharge electric ball valve and return electric ball valve open and close degrees, and is adopted as a target pressure difference. In the linkage adjustment step, through adjusting a high-pressure pump and the concentrated water side discharge and return electric ball valve open and close degrees, the target pressure difference and the target flow rate are achieved. With the method, the device and the system provided by the invention, cost is reduced, and control precision is improved.

Apparatus for combined processing of high-salinity high-COD sewage and processing method

The invention relates to an apparatus for combined processing of high-salinity high-COD sewage and a processing method. The sewage is subjected to a pre-treatment stage; after the pH value of the pre-treated sewage is adjusted to form an alkaline environment, the pH-adjusted sewage directly enters an oxidation evaporation reactor, so that organics in the pH-adjusted sewage are oxidized into carbon dioxide and water; and during sewage evaporation, salts in the sewage are concentrated and precipitate out through crystallization, thus the sewage in a semi-solid state enters a subsequent sludge roasting device for roasting, a very small amount of roasted inorganic salt ash can be processed as an ordinary solid waste or can be utilized by secondary recovery through re-purification technology. Through the processes of advanced oxidation, evaporation condensation and sludge roasting, organics in the sewage are oxidized to reduce the COD index, the salts in the sewage are concentrated and precipitate out through crystallization so as to facilitate forming of the semi-solid sludge, the evaporation-precipitated semi-solid sludge is subjected to roasting for harmless processing, so that a state is truly achieved that the sludge precipitated from the sewage is harmlessly processed while the sewage is processed.
