Advanced treatment method of high ammonia nitrogen wastewater

The invention discloses an advanced treatment method of high ammonia nitrogen wastewater. The method adopts a pre-denitrification-aerobiotic-post-denitrification process and an ozone-catalyzed oxidation tower advanced treatment process to treat the high ammonia nitrogen wastewater which has a TN value of greater than 500mg/L and a NH3-N value of greater than 400mg/L; by adjusting the delivery values of three streams of the wastewater flowing into a pre-denitrification tank, the mass ratio of C to N in the pre-denitrification tank is controlled to be more than 4, the dissolved oxygen (DO) of the pre-denitrification tank is controlled to be less than 0.5mg/L, the DO of an aerobiotic tank is controlled to be less than 1.5mg/L, the mixed liquor suspended solids (MLSS) of the aerobiotic tank can be controlled to be 4000-6000mg/L, and the mass ratio of C to N in a post-denitrification tank is controlled to be more than 2.5; finally, the product is subjected to high density precipitation andozone-catalyzed oxidation
