The invention belongs to the technical field of sewage treatment, and particularly relates to a method for treating sewage based on sludge biochar. The invention provides a method for treating sewage based on sludge biochar. According to the sewage treatment method provided by the invention, the specially-made sludge biochar is adopted, the sludge is mixed with the aluminum hydroxide and the carborane for segmented heat treatment, then the obtained pyrolysis sludge is mixed with the copper hydroxide for high-temperature heat treatment, and the obtained sludge biochar is developed in pore structure, high in porosity and uniform in pore size distribution; particularly, the adsorbent has a good adsorption effect on COD (Chemical Oxygen Demand) substances in sewage and is suitable for sewage treatment. By the adoption of the method, a large amount of domestic sewage is successfully treated, the national emission standard is met, and good economic benefits and social benefits are achieved. 本发明属于污水处理技术领域，具体涉及一种基于污泥
