[0038] In the present invention, appropriate amounts of medical stone and alkaline tourmaline are crushed and fed into a carbonization furnace together with an appropriate amount of diatomaceous earth for carbonization. After carbonization, the mixture is taken out and put into a feed port 4 together with activated carbon, activated alumina, zirconium nitrate, strontium nitrate, chitosan and acetic acid, and a dual-axis motor 5 is started;
