The present invention provides a treatment method for urea-containing copper ammonia wastewater. The method is directed at that the existence of a stable copper ammonia complex and a specific reason of containing urea seriously affect the treating process and effect of wastewater treatment for high concentration copper ammonium wastewater, employs the process of a combination method combined the copper sulfide precipitation method for removing copper with the magnesium ammonium phosphate precipitation method to process the copper ammonia complex, helps to solve the treatment of high concentration copper ammonia complex-containing wastewater, helps to overcome the problems that the urea removal for high concentration ammonia nitrogen wastewater is complex in operation process, high in processing costs, and high in energy consumption, has no need of an independent high temperature and high pressure treatment for the urea, is easy in operation and low in cost, and does not need to control the pH value and the temperature in the process. The treatment method can achieve the purpose of recycling resources, and has good social and economic benefits.
