Method for preparing composite activated carbon from multi-source carbonaceous raw materials

The invention discloses a method for preparing composite activated carbon from multi-source carbonaceous raw materials. The preparation method comprises the following steps: carbonizing bamboo wastes to obtain a bamboo carbonized material, grinding the bamboo carbonized material into powder, grinding waste coal-based activated carbon into powder, grinding a carbonaceous raw material for improving the strength of the composite activated carbon into powder, adding a certain amount of a binder and water into all the raw material powder according to a certain mass ratio, and stirring and forming; and drying, carbonizing and activating the formed material to obtain the composite activated carbon finished product. The biomass composite activated carbon product provided by the invention has the following advantages: (1) the method can be used for recycling the waste activated carbon, so that the treatment cost and the production cost are reduced; and (2) the method can be used for biomass raw materials such as bambo
