一、去漆化学清洗废水概况我厂平时对飞机机体及构件的表面进行防护处理时,通常是将原来残旧漆层脱净、洗净再重新喷涂需要的漆层。对于机体、构件上面的积炭、油污等,也用相应的金属清洗剂对其进行清洗去除。这种方法造成了较高浓度的废水需要处理,因化学成份较复杂和COD较高,解决比较困难。废水成份如下: 生产中的废水,含有多种有机化合物。其中既有常温脱漆剂(主要含二氯甲烷、汽油、煤油等),又有 First, to paint chemical cleaning wastewater Overview Our factory usually on the aircraft body and components of the protective surface treatment, usually the original old paint off the net, wash and then spray paint needed. For the body, the components above the coke, oil, etc., also use the appropriate metal cleaning agent to its removal. This method has resulted in a higher concentration of wastewater to be treated, due to the complexity of the chemical composition and COD higher, the solution is more difficult. Wastewater composition is as follows: wastewater in production, containing a variety of organic compounds. Among them, the room temperature paint remover (mainly containing methylene chloride, gasoline, kerosene, etc.), and there
