Background
The low-temperature plasma technology is widely applied to sewage treatment as an advanced oxidation technology. Dielectric barrier discharge is a form of generating low-temperature plasma, and the principle is that an insulating medium is placed in a discharge space or is covered on a discharge electrode, and micro-discharge is generated by using a small gap and a dielectric barrier form to generate low-temperature plasma. The sewage is treated by dielectric barrier discharge, mainly by utilizing high-energy electrons and ultraviolet light generated in the discharge process and the strong oxidation of some strong oxidizing substances. Compared with other forms of discharge, the dielectric barrier discharge has the advantages of high energy density and large energy volume of the generated low-temperature plasma, high reaction efficiency and low energy consumption.

The method for treating the exceeding iron and manganese ions in the underground water comprises the following steps: biological methods, chemical oxidation methods, adsorption methods, and the use of iron and manganese removal equipment. The biological method mainly uses the adsorption and catalysis of bacteria on the ferro-manganese, and has higher requirements on the environment of the water body, so that the concentration of dissolved oxygen in the water body needs to be ensured; the chemical oxidation method is to oxidize and precipitate iron and manganese ions in water by using chemical agents with strong oxidizing property, such as ozone, hydrogen peroxide, chlorine and the like, and is influenced by various factors such as the drug amount, the pH change, the oxidation time and the like due to different pH values of iron and manganese precipitate; the adsorption method is to utilize volcanic rock or zeolite to adsorb the ferro-manganese ions, the natural volcanic rock or zeolite has lower adsorption rate to the ferro-manganese ions, and modification treatment is needed; the iron and manganese removing equipment has a relatively complex process flow.
Therefore, it is important to find a method for removing iron and manganese ions with good effect and high efficiency.
