Embodiment 1

[0038] The following methods are adopted to carry out quenching and tempering treatment of reverse osmosis desalinated water of ships:

[0039] a. The transfer pump pumps the ship's reverse osmosis desalinated water from the ship's water tank;

[0040] b. The water from the transfer pump enters the flowmeter, and the monitored flow rate is 1.5m 3 / h;

[0041] c. The water quality of the ship’s reverse osmosis desalinated water before conditioning is monitored by the water quality meter I: pH6.5~6.7, total hardness 11.73~13.47mg / L, bicarbonate 4.30~4.45mg / L;

[0042] d. The outlet water of water quality meter I enters the pipeline mixer, and the 2 / 5, 3 / 5, 4 / 5 of the pipeline mixer form an angle of 120° to each other and add calcium chloride, magnesium sulfate and sodium bicarbonate to adjust and temper in sequence along the tangential direction of the water flow agent, the conditioner is dissolved in water quality meter I effluent to form calcium chloride aqueous solution, ma...

Abstract

The invention provides a conditioning method of boat reverse-osmosis seawater desalinated water. The conditioning method comprises the following steps: pumping the boat reverse-osmosis seawater desalinated water from a desalinated water cabin; detecting the water flow of the pumped boat reverse-osmosis seawater desalinated water by a flow meter; monitoring the water quality of the discharging water of the flow meter by a water quality monitor I; feeding the discharging water of the water quality monitor I into a pipeline mixer, and adding a conditioner into the pipeline mixer; monitoring the water quality of the discharging water of the pipeline mixer by the water quality monitor II, so as to obtain qualified conditioned desalinated water. The problems that the boat reverse-osmosis seawater desalinated water is deficient in nutrients, such as calcium and magnesium, and poor in stability and corrodes a boat water supply pipeline are solved. The nutritive and healthy conditioned desalinated water with stable water quality is supplied for a boat.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a conditioning method for ship reverse osmosis seawater desalination. Background technique [0002] Ship reverse osmosis desalinated water is soft water, lacks calcium, magnesium ions and other nutrients, has low hardness, alkalinity, and pH, basically has no buffer capacity, and has a tendency to dissolve the protective scale layer on the inner wall of the pipeline. Studies have shown that water hardness is negatively correlated with the mortality of cardiovascular and cerebrovascular diseases. Long-term drinking of insufficient or severely lacking mineral water will cause water and salt metabolism disorders and inhibit gastric acid secretion. The ship's water supply system is made of metal pipes. Corrosion of desalinated water leads to water quality pollution, and the phenomenon of increased chroma and iron content is common. [0003] Quenching and tempering trea...
