【Abstract】：Aiming atthe problemthatsilicon scaleaffects thequalityof produced water when treating siliconcontaining Wastewater with double membrane method，the photovoltaic wastewater containing alarge amount ofsilicon dioxide was used as raw water，andthe pilot test of the silicon removal effect of the double membrane method was adopted，and the role of coagulation and sedimentation pretreatmentonthe normal operation of the double membrane method was focused.The results showed that coagulation and sedimentation pretreatment can remove most of colloidal silicon and active silicon，thus efectively ensuring the operation of the follow-up double membrane system.
