The invention relates to a treatment process of papermaking recovery pulp. The treatment process is characterized by sequentially comprising the following steps that 1, papermaking white water is treated through a gas flotation method, and the recovery pulp is obtained; 2, the recovery pulp obtained in the first step is conveyed to a hardwood pulp pulper for pulping treatment, and the concentration in the pulp is stable; 3, the pulp obtained in the second step is blended into a pulp line for subsequent paper production. Compared with the prior art, the treatment process of the papermaking recovery pulp has the advantages of being high in concentration of the recovery pulp, stable in concentration of the pulp line and the like. 本发明涉及种造纸回收浆料处理工艺，其特征在于，该工艺依次包括以下步骤：(1)气浮法处理造纸白水，得到回收浆料；(2)将步骤(1)所得回收浆料输送到阔叶浆碎浆机进行碎浆处理，并使碎浆机中的浓度稳定；(3)步骤(2)所得浆料配入到浆线，进行后续造纸生产。与现有技术相比，本发明具有回收浆料浓度高，浆线浓度稳定等优点。
