Method and device for treatment of saline-alkali land |
| 摘要 |
A method for treatment of saline-alkali land is provided, comprising at least one self-circulating process, the self-circulating process comprising: step 1, converting saline-alkali water deposited in the saline-alkali land into acidic water by an electrolysis system, whereby the salt content of the acidic water is lower than that of the saline-alkali water; and step 2, leaching the saline-alkali land with leaching water comprising the acidic water. A device for treatment of saline-alkali land according to the above-described method is also provided, comprising: an electrolysis system for converting saline-alkali water deposited in the saline-alkali land into acidic water, whereby the salt content of the acidic water is lower than that of the saline-alkali water; and a leaching system for leaching the saline-alkali land with leaching water comprising the acidic water. |

1. A method for treatment of saline-alkali land, comprising at least one self-circulating process, wherein the self-circulating process comprises:
step 1, converting saline-alkali water deposited in the saline-alkali land into acidic water by an electrolysis system, whereby the salt content of the acidic water is lower than that of the saline-alkali water; and step 2, leaching the saline-alkali land with leaching water comprising the acidic water, wherein the electrolysis system comprises an electrolyte comprising the saline-alkali water deposited in the saline-alkali land. |
