Title: Method and device for removing heavy metal from contaminated water
Inventor: CHO EISHO
IPC: C02F1/62
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To remove heavy metal from contaminated water continuously by a method wherein contaminated water is introduced together with air into a charge cylinder filled with limestone so that heavy metal in the water is oxidized and made insoluble and the insoluble metal oxide is subjected to a primary filtration using a filter membrane and a secondary filtration using a separation membrane. SOLUTION: Ferrous sulfate is dissolved into distilled water to prepare water contaminated with iron component having a predetermined concentration and a charge cylinder 1 is filled with natural limestone 2 together with air and the contaminated water is supplied upwardly to the cylinder 1 to oxidize and make insoluble heavy metal in the water. And the water to be treated which contains iron oxide made insoluble is immediately introduced into an inverted-cone-shaped settling tank 3. Thereafter the water is subjected to a primary filtration using a filter membrane 4 to settle the oxide and further subjected to a secondary filtration using a separation membrane 5 to separate oxides which have not been settled in the primary filtration. Thus heavy metal can be removed continuously from contaminated water without separately adding quick lime, oxidizing agent, and flocculant.
