description A method for directly and deeply purifying high concentration organic wastewater, specifically includes the following steps of: (1) fortified precipitation treatment; (2) rapid filtration of sediment of suspended solids; (3) pH value adjustment; (4) hydrolysis acidification where pH value adjusted waste water enters a water distribution unit in which a biological hanging film filter is arranged to fortify an anaerobic hydrolysis acidification function of the waste water; and (5) bio-filter treatment. A rapid and low cost treatment method for high concentration, high ammonia and high nitrogen organic waste water is provided by means of water and air distribution by the biological filtering bed, an air-water backwashing bed layer structure, setting of a temperature regulation system for the biological filtering bed, and a combined process of the biological filtering bed with a fortified sedimentation unit, a suspension object sediment rapid filtration unit, and like unit structures.
