Hair products industry is an industry which processes wigs with the material of human hair and artificial fiber and so on.Its manufacturing process can be roughly divided into two periods: bleaching and dyeing,front and back processing.The bleaching and dyeing process use enormous water and the wastewater is difficult to deal with.The disposed solution of overacid,oxidation and bleaching and dyeing is directly let out after using it only once,which do not meet the clean production requirements.What's more,the discharged solution is still useful,it should be considered to be neutralized and multiusage.The process of bleaching and dyeing doesn't consider comprehensive utilization,consumes huge amount of water and results in enormous wastewater.All of the above processes can be improved through technological innovation and equipment reformation according to the requirements of clean production.
