本发明涉及水处理技术领域，具体公开一种回用水处理方法和处理系统。所述回用水处理方法为：回用水经过软化、过滤和阳离子交换后进行反渗透处理，所述反渗透处理包括一级反渗透处理和二级反渗透处理，且在该两级反渗透处理之间进行脱气处理，然后再进行阴阳离子交换处理；其中所述脱气处理的进水pH调节至4.3-5.2，脱气处理在0.1-0.3m3/kg的大气液比的条件下进行。本发明的回用水处理方法大大提高回用水处理效率，得到的回用水可直接作为高压锅炉用脱盐水。 The invention relates to the technical field of water treatment, and particularly discloses a reuse water treatment method and a treatment system. The reuse water treatment method comprises the stepsthat after being softened, filtered and subjected to cation exchange, reuse water is subject to reverse osmosis treatment, reverse osmosis treatment includes first-stage reverse osmosis treatment andsecond-stage reverse osmosis treatment, degassing treatment is conducted between the two stages of reverse osmosis treatment, and then anion-cation exchange treatment is conducted, wherein the pH of inlet water for degassing treatment is adjusted to 4.3-5.2, and degassing treatment is conducted at the atmospheric liquid ratio of 0.1-0.3 m3/kg. According to the reuse water treatment method, the reuse
