Device, structure and process for processing ammonia-nitrogen sewage by aeration zeolite fluidized bed

Abstract

The invention discloses a device, a structure and a process for processing ammonia-nitrogen sewage by an aeration zeolite fluidized bed, wherein the device comprises an upward flow filter; a filter plate is arranged in the filter; a zeolite filling material is arranged above the filter plate, and an air pipe and a water feeding pipe are arranged below the filter plate; a water outlet is arranged above the zeolite filling material; and an exhaust pipe is arranged at the top of the filter. According to the device, the zeolite filling material is made to flow in water by aeration, in order to absorb the ammonia and nitrogen in the water by zeolite; meanwhile, zeolite absorbers rub against each other to result in surface peeling off, and the fallen fine particles with ammonia and nitrogen absorbed flow away along with the flow, so the surface of the zeolite filling material is continuously renewed to develop a sustainable absorption, and the zeolite filling material is not regenerated; therefore, the problems of limited absorption capacity, frequent regeneration in processing high-concentration ammonia-nitrogen sewage and limited application of the zeolite in the prior art are solved.

Description

technical field [0001] The invention belongs to the field of ammonia nitrogen sewage treatment, and in particular relates to a device, a structure and a process for treating ammonia nitrogen sewage with an aerated zeolite fluid bed. Background technique [0002] The excessive discharge of ammonia nitrogen leads to eutrophication of marine and terrestrial water environments, and the treatment of ammonia nitrogen wastewater has attracted more and more attention. Ammonia nitrogen pollution comes from domestic sewage, landfill leachate and industrial wastewater drainage, and the pollution sources are widely distributed, so it is of great significance to solve the problem of ammonia nitrogen treatment. [0003] The main methods for treating ammonia nitrogen pollution and wastewater are biochemical and physical and chemical methods. At present, the biochemical method is mainly biological denitrification, and the physical and chemical method mainly includes breakpoint chlorination...
