Aiming at the difference of biodegradable properties of a great amount of organisms in high-concentration organic waste water at present and according to the current situation of the treatment processAiming at the difference of biodegradable properties of a great amount of organisms in high-concentration organic waste water at present and according to the current situation of the treatment processof high-concentration organic waste water, the invention provides a combined treatment process for high-concentration organic waste water, which has high waste water removing efficiency and wide appl of high-concentration organic waste water, the invention provides a combined treatment process for high-concentration organic waste water, which has high waste water removing efficiency and wide application range and combines a micro aerobic bacteria treatment process, a chemical oxidation process and an activated sludge process. In the combined treatment process, the micro aerobic bacteria treatication range and combines a micro aerobic bacteria treatment process, a chemical oxidation process and an activated sludge process. In the combined treatment process, the micro aerobic bacteria treatment process is firstly adopted to remove most of biodegradable organisms so as to ensure that the object treated by the chemical oxidation process is basically nonbiodegradable organisms; the chemicament process is firstly adopted to remove most of biodegradable organisms so as to ensure that the object treated by the chemical oxidation process is basically nonbiodegradable organisms; the chemical oxidation process is adopted to improve the biodegradability of the waste water so as to lay a foundation for the subsequent biological treatment; and at last the activated sludge process is used asl oxidation process is adopted to improve the biodegradability of the waste water so as to lay a foundation for the subsequent biological treatment; and at last the activated sludge process is used aspost treatment so as to ensure the quality of outlet water. The process can be directly applied to different types of high-concentration organic waste water containing high content of oil, sulfur and post treatment so as to ensure the quality of outlet water. The process can be directly applied to different types of high-concentration organic waste water containing high content of oil, sulfur andammonia, and has the advantages of high removing efficiency, low sludge output and wide application range. ammonia, and has the advantages of high removing efficiency, low sludge output and wide application range.
