The invention provides a semiconductor industry acid-alkali wastewater recycling system, which comprises a wastewater recycling module, a recycling water tank, a raw water tank, a filtering module and a purifying module which are connected in sequence, and is used for treating wastewater treated by a semiconductor enterprise. Compared with the mode that the semiconductor enterprises generally discharge treated wastewater to urban sewage treatment plants in the related technology, the method has the advantages that the wastewater treated by the semiconductor enterprises can be treated and recycled, so that the environmental pollution is reduced, and the resource recycling of the wastewater is realized at the same time; and the method is green, environment-friendly and energy-saving. 本申请提供了一种半导体行业酸碱废水的回收利用系统，通过设置包括依次连接的废水回收模块、回用水池、原水池、过滤模块和净化模块的半导体行业酸碱废水的回收利用系统，对半导体企业处理后的废水进行处理，得到能够回收利用的纯水，与相关技术中半导体企业一般将废水经处理后排往城市污水处理厂的方式相比，可以对半导体企业处理后的废水进行处理并回收利用，减少环境污染的同时实现了废水的资源化回收利用，具有绿色环保节能的优点。
