The invention belongs to the field of environmental protection and chemical engineering, and particularly relates to a production process for recycling phenol residual liquid. The production process is implemented by the aid of a raw material storage tank, a delivery pump, a tower bottom kettle, an electric heater, a rectifying tower, a condenser, a vacuum pump, a reflux ratio controller, collecting tanks, a venturi tube mixer, a phenol collecting tank, an extracting and separating tank, a circulating pump, a forced mixer, a static mixer, a pressure pump, an emulsifier storage tank, a fuel oil storage tank, an emulsified fuel oil collecting tank, a cryogenic device and an activated carbon adsorption device. The production process mainly includes process procedures of crude distillation separation, rectification separation, phenol purification, waste gas treatment and residue recycling. The process procedures are in intermittent production modes.
