The invention provides a set of seawater desalination and reclamation conditioning devices. A seawater desalination water inlet pipeline is connected to a water inlet of a carbon dioxide absorbing tower; a water outlet of the carbon dioxide absorbing tower is connected to a water inlet of a seawater desalination water tank; one end of a main pipeline is connected to a water outlet of the seawater desalination water tank while the other end of the main pipeline is connected to a water inlet of a lime milk pipeline mixer; a seawater desalination water pump and a first online PH meter which is interlocked with a carbon dioxide gas regulating valve are arranged on the main pipeline; an outlet pipeline of the lime milk pipeline mixer is connected to a conditioning water tank, and a second online PH meter which is interlocked with a lime milk adding metering pump is arranged on a connecting pipeline. The whole set of system equipment is controlled by virtue of a PLC (Programmable Logic Controller) or a DCS (Distributed Control System), and is used for supplementing a certain quantity of mineralized materials into desalinated seawater in an accurate adding manner so as to guarantee residents in good health and simultaneously protecting the safe running of water supply networks.

The invention relates to the technical field of new material processing, and discloses a method for improving the corrosion resistance of magnesium alloy valves. The prepared corrosion-resistant coating material is co-electrodeposited with zinc ions to the magnesium alloy valves to be plated by metal electrodeposition. On the workpiece, a dense layer with a thickness of 10.0-12.0 microns is formed to obtain a composite coating, which acts as an inert anti-corrosion barrier, prevents corrosion, remains stable in acidic media, can withstand the test of general high temperature, and reduces stress corrosion. Sensitivity, can inhibit the occurrence of electrochemical corrosion, the invention can significantly improve the corrosion resistance of magnesium alloy valves, solve the problems of high porosity and unstable protective properties of corrosion-resistant coatings for existing magnesium alloy valves, and have no pollution The waste liquid is produced without toxicity, and the economic and social benefits are significantly improved.
