The invention discloses a treating device for salt-washing waste water in improvement of saline-alkaline lands. The treating device comprises a groove body, wherein the groove body is internally provided with a reaction chamber and a clean-water chamber in sequence; a water distributing pipe communicated with a water feeding pipe is arranged at the bottom part of the reaction chamber; a gas distributing pipe communicated with a gas feeding pipe is arranged above the water distributing pipe; the reaction chamber is internally provided with at least one pair of parallel electrodes; water-passinggaps are left among all the electrodes; the upper part of one end of the clean-water chamber, away from the reaction chamber, is provided with a water discharging pipe; the position of the clean-water chamber, close to the water discharging pipe, is provided with a water blocking plate; a water discharging gap is arranged between the lower end of the water blocking plate and the bottom part of the clean-water chamber; a slag discharging device is arranged at the bottom part of the clean-water chamber; the water blocking plate is provided with a mudguard extending towards the inclined lower part of one side close to the reaction chamber at the bottom part of the clean-water chamber; an overflowing groove is arranged in the water blocking plate and above the mudguard. The treating device disclosed by the invention has the advantages that the salt-washing waste water in improvement of the saline-alkaline lands can be effectively improved so as to be reused.
Description
technical field [0001] The invention relates to a waste water treatment technology, in particular to an improved salt washing waste water treatment device for saline-alkali land. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, the soil is alkaline, the organic matter content of saline-alkali soil is small, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops. Promote seedlings. In order to reduce the saline-alkali content of saline-alkali land, improving saline-alkali land by washing salt is a method of improving saline-alkali land, that is, pouring water into the saline-alkali land to dissolve the soil sal...
