System and method for treating and recycling silicon powder particle-containing wastewater in photovoltaic industry

The invention belongs to the field of treatment and recycling of particle-containing wastewater, and concretely relates to a system and a method for treating and recycling silicon powder particle-containing wastewater in the photovoltaic industry. The treatment and recycling system is characterized in that the system comprises a particle-containing wastewater collection tank, a particle-containing wastewater transfer pump, a plate and frame filter press, a clear liquid tank, a clear liquid transfer pump, a quartz sand filter and a recycled water tank, and a control valve is arranged between every two adjacent units. The particle-containing wastewater in the photovoltaic industry is recycled to the production process, so sewage emission is reduced, and the recycling of water resources is realized. 本发明属于颗粒废水的处理回用领域，具体涉及到种光伏行业含硅粉颗粒废水的处理回用系统及方法，其特征在于：所述处理回用系统及方法包括颗粒废水收集池、颗粒废水转移泵、板框压滤机、清液池、清液转移泵、石英砂过滤器、回用水池，所述各单元之间均设有控制阀门，本发明的优点和积极效果是：将光伏行业的颗粒废水处理后回用至生产工艺，既减少污水排放，又实现水资源的循环利用。
