Abstract

The invention provides a baffling type ammonia removal, denitrification and aeration biological filter tank. The baffling type ammonia removal, denitrification and aeration biological filter tank mainly comprises a filter tank, wherein a water inlet is formed in the upper part of a left side wall of the filter tank, and a water outlet is formed in the upper part of a right side wall of the filtertank; the filter tank is internally provided with a plurality of baffling filtering units; each baffling filtering unit comprises a baffle plate, a supporting plate and a filling frame; a water distribution channel is formed between every the two baffling filtering units; a medicament supplementing device is arranged at the top of each water distribution channel; each medicament supplementing device is internally filled with an alkalinity medicament or a carbon source. The filter tank provided by the invention is scientific and reasonable in structure, can be used for supplementing the alkalinity or the carbon source, and has good ammonia removal and denitrification effects.

Description

technical field [0001] The invention relates to the field of treatment devices for removing ammonia and nitrogen from high-concentration ammonia nitrogen wastewater, in particular to a baffle type biological aerated filter for removing ammonia and nitrogen. Background technique [0002] At present, ammonia nitrogen treatment methods mainly include evaporation method, gas method, stripping method, struvite chemical precipitation method, ion exchange method and biological method. Among them, except the biological method, the other methods are physical and chemical treatment methods, which have the disadvantages of high investment cost, high operation cost, and inability to meet the standard stably. Moreover, the biological method of ammonia nitrogen removal is mainly concentrated in the treatment of wastewater with an ammonia nitrogen concentration of less than 150mg / L. There are few researches and applications on the treatment of ammonia nitrogen concentrations between 500-70...
