| titleOfInvention | High-concentration ammonia nitrogen wastewater treatment method |
| abstract | The invention discloses a high-concentration ammonia nitrogen wastewater treatment method which includes the first step that high-concentration ammonia nitrogen wastewater enters a chemical reaction sedimentation basin and forms a magnesium ammonium phosphate precipitate through chemical reaction, and the concentration of NH3-N in the wastewater is reduced; the second step that the wastewater enters an ozone oxidation tower, and specific pollutants N, N- dimethylacetamide in the wastewater is decomposed to be the NH3-N; the third step of the wastewater mixed with other wastewater enters a regulating reservoir, and the biodegradability and carbon nitrogen ratio of effluents of the ozone oxidation tower can be improved; the fourth step of the wastewater flowing from the regulating reservoir is mixed with a part of wastewater processed through a membrane bioreactor pool, the mixture enters an anoxic pond, and nitrate nitrogen and organic pollutants in the wastewater are removed through the denitrification of microorganisms; the fifth step that the wastewater enters the membrane bioreactor pool, suspended solids, ammonia nitrogen and the organic pollutants in the wastewater are removed; the sixth step that the other part of wastewater processed by the membrane bioreactor pool enters an adsorption tank, and the pollutants in the wastewater can be removed through the absorption of activated carbon; the seventh step of the wastewater processed by the adsorption tank is recycled or discharged outside. |
