Chemical emissions from the production process are mostly plex, poisonous and harmful and difficult to degrade toxic organic pounds and biological pollutants, including concentrations as high as tens of thousands of COD, BOD concentrations up to several thousand mg / L. If not treated properly, will cause serious pollution and destruction to the environment. In view of its wastewater quantity was small and cosmetics industry wastewater characteristics, consider the cost, processing technology, access to water quality and other factors, ultimately determine the process as air flotation HydrolysisSBR. First, the process has a grill, adjust the pool, pretreatment of wastewater to remove larger suspended particles in water and adjust the quality and quantity. Floating can effectively remove most of the oil LAS and emulsification state, and remove material CODCr caused by oil, benefit to the followup biochemical treatment treatment using hydrolysis acidificationsbrcontact oxidation/SBR joint process, can effectively remove the water in the SS and CODcr. Through the grille, regulatio
