The invention provides a rotary calcining furnace feeding area structure for treating radioactive waste liquid. The feeding area structure comprises a feeding pipe, a waste liquid feeding port and a tail gas exhaust pipe. The feeding pipe is divided into an upper part and a lower part by a partition plate, and the partition plate is provided with vent holes to form a gas flow channel of the upperhalf part and a liquid flow channel of the lower half part; the waste liquid feeding port communicates with the liquid flow channel, and the tail gas exhaust pipe communicates with the gas flow channel through an inclined pipe section; and a calcining furnace feeding hole is formed in the bottom of the liquid flow channel. The feeding area structure adopts a brand-new independent design, has the advantages of simple and compact structural design, space saving, light structural weight, convenience in long-term stable operation of the process and the like, effectively realizes gas-liquid separation of waste liquid feedi
