Processing method of high concentration ammonia nitrogen waste water

The invention relates to a method for processing high-concentration ammonia-nitrogen wastewater, which is realized by the following steps: adjusting the pH value of the wastewater; adjusting the temperature of the wastewater; removing ammonia under the high temperature; re-adjusting the pH value; and blowing off deamination. The method has the advantages that industrial wastewater with the concentration of ammonia nitrogen being more than 10000 mg/L and the concentration of CODCr being about 20000-30000 mg/L can be reduced to the industrial wastewater with the concentration of the ammonia nitrogen being about 300 mg/L and the concentration of the CODCr being about 8000-15000 mg/L through being processed, thereby reducing the toxicity of ammonia nitrogen to subsequent biochemical treatment, and achieving the discharge of the ammonia nitrogen up to standard in combination with subsequence biological denitrification.
