1. Adopting steam stripping + rectification technology to recover ammonia from wastewater in the form of concentrated ammonia water, high concentration ammonia gas or liquid ammonia. After deamination, ammonia nitrogen content in wastewater is below 10mg/L, realizing resource recovery and utilization of ammonia nitrogen;
2. Using multiple energy comprehensive utilization technologies to effectively utilize system heat, with a steam consumption of generally 80-100kg per ton of wastewater;
3. Realizing recovery and reuse of 15%-20% concentrated ammonia water.
