Abstract

The invention discloses a method for treating ammonia nitrogen wastewater by using a heterotrophic nitrification-aerobic denitrification pseudomonas strain, wherein the ammonia nitrogen wastewater contains organic acid sodium, and a C / N ratio is 8-120. The method comprises: inoculating a heterotrophic nitrification-aerobic denitrification pseudomonas seed liquid into ammonia-nitrogen wastewater, and carrying out am oscillation reaction for 6 h-7 d at a temperature of 25-40 DEG C at a rotating speed of 90-180rpm so as to finish the treatment of the ammonia nitrogen wastewater, wherein the strain is pseudomonas LJ9, is preserved in the Guangdong culture collection center, has the preservation number of GDMCC NO:60339, and has high tolerance to high C / N and high ammonia-nitrogen concentrationwastewater and high ammonia-nitrogen removal rate, so that the method has huge application value in the fields of ammonia nitrogen removal of high carbon-nitrogen ratio and high-concentration ammonia-nitrogen wastewater.

Description

technical field

[0001] The invention relates to the technical field of microbes, in particular to a method for treating ammonia nitrogen wastewater by using heterotrophic nitrification-aerobic denitrification Pseudomonas strains. Background technique

[0002] In recent years, the problem of water pollution has become increasingly serious. Nitrogen is an important pollution factor in water. Excessive nitrogen flowing into water can easily cause eutrophication of water, cause insufficient dissolved oxygen in water, lead to deterioration of water quality, and change water ecology. The environment, endangering the survival of aquatic organisms, is extremely harmful to the environment and human health. Nitrogen exists in water bodies in the form of organic nitrogen and inorganic nitrogen. The main source of organic nitrogen is domestic sewage, agricultural nitrogen fertilizer and industrial wastewater; Nitrate nitrogen, of which nitrate nitrogen can be converted into nitrite nit...
