Abstract: PURPOSE: An electrokinetic meditation apparatus for anionic contaminants using a sacrificial anode is provided to purify the anionic contaminants in soil polluted with the anionic contaminants without a separate basic electrolyte processing for changing the pH of the entire soil to the basic condition, by removing hydrogen ions generated in an anode. CONSTITUTION: An electrokinetic meditation apparatus for anionic contaminants comprises an anode(20), a cathode(30), an anode electrolyzer(50), and a cathode electrolyzer(52). The anode and cathode are positioned on both sides of soil polluted with the anionic contaminants, and form an electric field on the contaminated soil. An anode-electrolyte and an cathode-electrolyte for supplying electrolytes to the anode and cathode are respectively stored in the anode electrolyzer and cathode electrolyzer, respectively. The anode itself is oxidized and is made of components consisting of the soil. A sacrificial anode is any one selected from iron, aluminum, or their alloys. The sacrificial anode is a bent form or has scratches on the surface. [Reference numerals] (AA) Polluted soil
Abstract translation: 目的：提供一种使用牺牲阳极的阴离子污染物的电动冥想装置，用于净化污染了阴离子污染物的土壤中的阴离子污染物，而无需单独的碱性电解质处理，可将整个土壤的pH值改为基本条件，通过除去氢离子 在阳极中产生。 构成：用于阴离子污染物的电动冥想装置包括阳极（20），阴极（30），阳极电解器（50）和阴极电解器（52）。 阳极和阴极位于被阴离子污染物污染的土壤两侧，并在污染土壤上形成电场。 用于向阳极和阴极供应电解质的阳极电解质和阴极电解质分别分别存储在阳极电解槽和阴极电解槽中。 阳极本身被氧化并由由土壤组成的组分制成。 牺牲阳极是选自铁，铝或其合金中的任何一种。 牺牲阳极是弯曲形式或在表面上具有划痕。 （附图标记）（AA）污染土壤
