The invention provides a chemical agent tank cleaning method which comprises the steps that a motor is started, a movable impeller is driven by the motor to rotate, then water in an agent tank or an agent barrel is stirred in the agent tank or the agent barrel, polyacrylamide is continuously dissolved in the water body in the stirring process, meanwhile, a Fenton reagent is added, the polyacrylamide is degraded by the Fenton reagent in the water body, and thus the chemical agent tank is cleaned. And continuously adding a Fenton reagent until the residual polyacrylamide emulsion in the tank body is oxidized and degraded, the tank washing wastewater basically has no viscosity and the tank body is cleaned up, and finally pouring out the tank washing wastewater for next-step treatment. According to the method, a small amount of residual polyacrylamide emulsion in the tank body is oxidized and degraded by virtue of an advanced oxidation technology, the tank body is quickly and effectively cleaned, the tank body is
