摘　　要：根据锂电池三元前驱体材料废水处理要求,前驱体洗水通过超滤装置、反渗透装置,所产浓水与前驱体母液合并,混合之后经过汽提脱氨和MVR蒸发结晶处理,最终实现零排放标准。其中汽提脱氨的低温冷凝水回用锅炉房,MVR蒸发结晶所产冷凝水回收利用,最终降温回一级RO装置制备纯水回用于生产。整个系统将低温冷凝水进行有效分配和利用,节能降耗,确保系统稳定运行。According to the requirements for wastewater treatment of ternary precursor materials for lithium batteries,the precursor washing water is combined with the precursor mother liquor through ultrafiltration and reverse osmosis devices.After mixing,it is subjected to stripping,deamination,and MVR evaporation crystallization treatment,ultimately achieving zero emission standards.The low-temperature condensate water from stripping and deamination is reused in the boiler room,the condensate water produced by MVR evaporation crystallization is recycled,and finally cooled back to the primary RO device to prepare pure water for reuse in production.The entire system effectively distributes and utilizes low-temperature condensate,saving energy and reducing consumption,ensuring stable operation of the system.
