Recently, as the production of canning foods promotes a lot, a growing number of canning factories are under construction, and some of which are reconstructed. There are so much organic wastewater let out during the process of canning food production, so the sewage disposal must be taken into consideration accomplished with the construction of canning factories. So this paper takes the high concentration of organic wastewater from canning factories as the research object, whose main route is to use the oil the oil removal + hydrolysis + AO to deal with the high concentration of organic wastewater via theory analysis and practical investigation. This paper also gives a deeper analysis of the project designation, construction and operation of bread factories where the oil removal + hydrolysis + AO are applied. This paper also gives a brief introduction of the origin, characteristics and meaning of governing to the organic wastewater, the research and appliance of it both at home and abroad. Meanwhile, this paper explains the characteristics of the oil removal + hydrolysis + AO. Through the research and analysis of the oil removal + hydrolysis + AO station which has been applied in the process of production. Thi
