某城市工业区内一汽车制造厂扩建年加工5万辆汽车车身涂漆车间,生产工艺为:清洗除油→水清洗→磷化→水清洗→涂底漆→水清洗→干燥→喷中漆→烘干→喷面漆→烘干。清洗除油采用NaOH和合成洗涤剂,磷化使用磷酸锌、硝酸镍,涂底漆使用不含铅的水溶性涂料,中漆和面漆含甲苯、二甲苯,烘干采用热空气加热方式。生产过程废气污染源主要有喷漆过程产生的废气喷漆室废气量为8.6×104m3/h,漆雾浓度680mg/m3,漆雾含甲苯12mg/m3,由30m高的排气筒排放,两个烘干室废气量均为2.1×104m3/h,含甲苯浓度86mg/m3,废气采用直接燃烧法处理,净化效率96.5%,分别由各自30m高的排气筒排放,两排气筒相距50m。生产过程产生的废水有含油废水、磷化废水和喷漆废水,均入汽车制造厂污水综合处理站处理达标后排入城市污水处理厂,产生的工业固体废物有漆渣、磷化滤渣,污水处理站的污泥,厂址东侧有一乡镇。

给出喷漆室可采用的3种漆雾净化方法。
