The application discloses a method for preparing formed fuel by mixing semi-dried sludge and oil-tea camellia fruit hulls, and the method comprises the following steps: (1) washing and drying the oil-tea camellia fruit hulls, then crushing and sieving the oil-tea camellia fruit hulls to obtain oil-tea camellia fruit hull powder; drying high-moisture sludge to obtain semi-dried sludge; (2) baking the oil-tea camellia fruit hull powder under a mixed atmosphere of oxygen and nitrogen to obtain baked oil-tea camellia fruit hulls, or pyrolyzing the oil-tea camellia fruit hull powder under a nitrogen atmosphere to obtain oil-tea camellia fruit hull biochar; (3) mixing and stirring the semi-dried sludge and the baked oil-tea camellia fruit hulls or the oil-tea camellia fruit hull biochar, uniformly placing water, and then preparing formed fuel. The method is simple, easy to operate and low in cost, the prepared formed fuel particles can realize rapid reduction of urban sludge and recycling of energy, and the method has the advantages of low energy consumption, high particle strength, no pollution and the like when the formed particles are prepared.
