Deoxygenation catalyst and preparation method thereof, and method for removing dissolved oxygen in reclaimed water

The embodiment of the invention discloses a deoxygenization catalyst, a preparation method thereof and a method for removing dissolved oxygen in reclaimed water. The application range comprises the field of reclaimed water treatment and feed water treatment, and efficient deoxygenization can be realized within a short time and at a low reaction temperature. The catalyst comprises a mesoporous molecular sieve SBA-15 and predetermined active metal, and the predetermined active metal enters the mesoporous molecular sieve SBA15 in an impregnation manner. The method is suitable for the reclaimed water treatment process. 本发明实施例公开一种除氧催化剂及其制备方法、去除再生水中溶解氧的方法，应用范围包括再生水处理及给水处理领域，能够在短时间内、低反应温度下实现高效除氧。所述催化剂，包括：介孔分子筛SBA-15和预定活性金属，所述预定活性金属通过浸渍方式进入所述介孔分子筛SBA-15中。本发明适用于再生水处理过程。
