Abstract

The invention discloses an anode material suitable for external cooling water treatment. The anode material consists of a substrate layer, an intermediate layer and a catalytic oxidation layer from inside to outside. The substrate layer is a treated titanium layer, and the intermediate layer is ion sputtered. The supported TiN layer, the catalytic oxide layer is IrO doped with La, Sb, carbon nanodots, dodecyl dimethyl betaine 2 -RuO 2 Floor. The anode material suitable for external cooling water treatment of the present invention solves the problem in the prior art that the concentration of salt and organic matter in the external cooling water increases due to the addition of chemical substances, and greatly shortens the service life and treatment efficiency of the reverse osmosis membrane. It causes the increase of concentrated water volume and the unsatisfactory effect of purified water quality. The invention also discloses a method for preparing an anode material suitable for external cooling water treatment, and a treatment method suitable for external cooling water treatment.

Description

Anode material, preparation method and treatment process suitable for external cold water treatment technical field The invention belongs to the technical field of water treatment, relate to a kind of anode material that is applicable to external cold water treatment, the present invention also The invention relates to a preparation method of the above anode material and a treatment process suitable for the treatment of external cold water. Background technique Converter valve is one of the core equipment of high-voltage direct current power transmission, it can generate a lot of heat in the operation process, needs The valve cooling water system cools it down. Usually, the valve cooling water system consists of an in-valve chilled water system (closed) and an out-valve chilled water system (open) structure, the cold water system in the valve uses deionized water as the medium, which is responsible for discharging the heat generated by the valve assembly to the valve ...
