description The invention discloses a treatment method for wastewater with high harmful organic matter content and high ammonia nitrogen content, belongs to the technical field of wastewater treatment, and aims to solve the problems of wastewater treatment load increase, large occupied area, high investment and the like in the existing method for treating high-ammonia-nitrogen wastewater. According to the treatment method of the invention, carbonate removal, ammonia distillation and hydrogen peroxide advanced oxidation treatment are carried out on the wastewater produced in a coal gas indirect cooling water process in a chemical fertilizer enterprise taking anthracite or coke as a raw material of a gas making furnace, so that ammonia nitrogen is removed in the treatment process, the salt content is not increased, the requirement for COD is finally lowered, and effluent can be directly used as circulating cooling water. According to the method, calcium hydroxide is added to remove carbonate, sodium hydroxide is added to s
