The invention discloses a method for producing
activated carbon by thermally activating a
coal tar dreg /
sludge mixed
fermentation body by using microwaves. The method comprises the steps of: firstly crushing and
grinding coal tar dreg into more than 200 meshes, then, mixing the ground
coal tar dreg with
sludge, and performing aerobic
fermentation for 10-20 days; then, adding
zinc chloride servingas an activator into the mixed
fermentation body, and infiltrating for 12-24h at 70-80 DEG C, wherein the added
zinc chloride is 0.5-4 times more than the mixed fermentation body in
mass; and finally, carbonizing and activating for 30-120min in a
microwave carbonization furnace under a N2 protection condition to obtain
coal tar dreg /
sludge mixed
activated carbon, washing with water till a neutralcondition is achieved, and
drying to obtain a product disclosed by the invention. The method disclosed by the invention has the advantages of simplicity and convenience for operation, easiness for control, low cost, high product synthesis rate and favorable product performance, and can be widely applied to
industrial wastewater treatment,
refractory wastewater treatment, sound insulation,
noise reduction, deodorization,
oil absorption, lipid suction and other industries.
