     DETAILED DESCRIPTION OF THE INVENTION 
     As is shown in the FIGURE, a water quality optimization system of the invention comprises a high-pressure water pump, a water purification device, a water storage device, a controller, a solar power source, a pH value regulation device and a water magnetization device. 
     The water purification device comprises a filter, a water electrolysis device, a reverse osmosis (RO) device, an RO rear active carbon filter device and an ultraviolet sterilization device. 
     The filter, the water electrolysis device, the reverse osmosis (RO) device, the RO rear active carbon filter device and the ultraviolet sterilization device are sequentially connected in series, the filter is connected with the pH value regulation device, and the ultraviolet sterilization device is connected with the water storage device. 
     An inlet of the high-pressure water pump is connected with a pure water source, an outlet of the high-pressure water pump is connected with the pH value regulation device, the pH value regulation device is connected with the water storage device through the water purification device, and the water storage device is connected with a system outlet through the water magnetization device and further connected with the inlet of the high-pressure pump through valves; the water storage device comprises a pH value detector, the signal output end of the pH value detector is connected with the controller, and the control ends of the valves and the control end of a high-pressure water pump driving circuit are all connected with the controller. 
     The valves are electromagnetic valves, and the water storage device comprises a plurality of water receivers. The water receivers are connected with the inlet of the high-pressure water pump through the corresponding electromagnetic valves respectively. 
     According to the embodiment of the invention, the pH value of pure water provided by the water source is detected and then balanced and regulated, no additive is added during the balancing and regulating process, the water is electrolyzed and balanced into acid water or alkaline water by an electrolysis method according to the pH value of the water, and the system can further regulate the pure water into alkalescent water for drinking and make the water reach the standard of optimal drinking water. 
     Certain impurities can be generated after the pH value of the pure water is balanced and need to be isolated and removed through the filter device, the pure water then enters a water softening device of the water electrolysis device and is changed into soft water by reducing the hardness of the water to 70 mg/l or below according to the ion exchange principle, namely by exchanging Mg 2+ Ca 2+  with Na + , and thus the pure water is optimized. 
     The optimized pure water is comprehensively filtered (such as impurities and heavy metal) and sterilized through the reverse osmosis (RO) device and enters the water storage device after passing through the active carbon filter device and the stainless steel high-energy ultraviolet sterilization device. 
     The water storage device starts a circulating device to activate the pure water according to the pH value and storage time of water in each water tank, and the specific process is as follows: the pH value is monitored through the pH value detector in the water storage device, if it is found that the pH value of water in a certain pure water tank does not meet the standard, an alarm can be given to the controller of the system and be synchronized into a master monitoring system of a central control room, the controller starts the high-pressure water pump and opens the corresponding electromagnetic valve, pure water in the water tank not meeting the pH value standard is circulated, and thus the pure water can be balanced circularly. Meanwhile, the storage time of water in each tank is recorded and stored in the controller and a master control system of the central control room, if the pure water in a certain water tank is not utilized in a set period of time, the master control system of the central control room can give out a command to the circulating system, and the pure water in the tank is activated circularly. 
     Finally, the water storage device supplies water to the magnetization device according to the production requirement, and then the water is supplied to an automatic bottled water production system to be bottled and packaged.
