At room temperature, the solubility is 2.0g / l, and it is in a dilute solution state in water. Under this condition, chemical reduction reaction is not active and must undergo multiple reactions before degradation. This scheme adopts a three-stage catalytic fixed bed reactor and uses different reducing agents and catalysts to degrade perchlorate in water in stages. The total degradation rate of the three-stage superposition is estimated to be 85% through experiments, that is, it is degraded from about 10 mg / l to about 1.5. Chemical degradation can still be carried out, but the efficiency is not high and the cost-effectiveness is not good. In this regard, other degradation methods are selected, and ion exchange is the best choice. In this regard, this scheme adopts a two-stage anion exchange method. The total degradation efficiency of the two-stage superposition is about 75%. The exchange resin uses a targeted resin specifically for perchlorate. The two groups are used in combination according to the concentration difference. After ion exchange, it reaches about 0.45 mg / l, which meets the new emission standards. The degradation process of perchlorate and the destination of degradation products: Taking potassium perchlorate as an example: KCLO4, KCLO3, KCLO2, KCLO, KCL. The final product is: KCL, which is harmless and discharged into the water body. When the stable installation component 22 is in use, the built-in frame 1 is first pre-buried underground. When the built-in frame 1 is placed, the water perchlorate removal component 21 is installed inside the built-in frame 1.
