The invention discloses a method for rapidly degrading hydrogel and recycling water resources, which comprises the following steps: (1) adding chloroquine substances into hydrogel wastes, and fully reacting at room temperature for 15 seconds to 5 minutes; (2) after the hydrogel is layered and solutes are fully separated out to form agglomerates, centrifuging or filtering the agglomerates; and (3) recovering water resources in the supernate or filtrate. After the hydrogel is treated, the viscosity of the hydrogel is reduced in a cliff mode, the highest reduction amplitude reaches 12269 times, the overall viscosity of the treated hydrogel solution is lower than 50 mPa.s and is close to the viscosity of tap water, so that the water resources can be recycled. 本发明公开了一种快速降解水凝胶回收水资源的方法，包括以下步骤：(1)在水凝胶废弃物中添加氯喹类物质，于室温下充分反应15s～5min；(2)待水凝胶分层、溶质充分析出形成团聚物后，离心或者过滤；(3)回收上清液或者滤过液中水资源。水凝胶在处理后粘度出现断崖式下降，最高降幅达12269倍，处理后的水凝胶溶液整体粘度低于50mPa·s，接近自来水粘度，可进行水资源的回收利用。
