The cooling water circulation recovery device comprises a small recovery pool, a pump and a big multilevel recovery pool which are sequentially communicated with each other. The small recovery pool and the pump are on the same surface with an inner waterway pipe network of a production system, and a certain height difference is between the big multilevel recovery pool and the inner waterway pipe network of the production system. The small recovery pool is communicated with an outlet of a cooling pipe of a reduction reaction tank of the inner waterway pipe network of the production system and an outlet of a cooling pipe of a diazo reaction tank of the inner waterway pipe network of the production system. The big multilevel recovery pool is communicated with an inlet of the cooling pipe of the diazo reaction tank and the inner waterway pipe network of the production system. The cooling water circulation recovery device utilized during the production of dinitrodiazophenol has the advantages of being capable of achieving cyclic utilization of cooling water during the production of the dinitrodiazophenol, saving water resource and reducing production cost.
