WATER PURIFICATION METHOD |
摘要 |
A water purification method comprising adding a purification agent to water having a contaminant concentration of 1 μg/L to 10 g/L, the purification agent containing an adsorbent having an average particle size of 100 nm to 500 μm, an iron-based flocculant, and an alkaline substance; causing the adsorbent to adsorb at least a part of the contaminants in water; settling the adsorbent with the adsorbed contaminants by the iron-based flocculant; and removing the sediment from water, wherein the purification agent is added in an amount of 0.01 g to 20 g per liter of water, can purify contaminated water conveniently and efficiently. |

1. A water purification method comprising:
adding a purification agent to water having a contaminant concentration of 1 μg/L to 10 g/L, the purification agent containing an adsorbent having an average particle size of 100 nm to 500 μm, an iron-based flocculant, and an alkaline substance; causing the adsorbent to adsorb at least a part of the contaminants in water; settling the adsorbent with the adsorbed contaminants under the effect of a water-insoluble ferric hydroxide produced by reaction of the iron-based flocculant and the alkaline substance to form a sediment; and removing the sediment from water, wherein the purification agent is added in an amount of 0.01 g to 20 g per liter of water. |
