The invention relates to the field of environmental protection treatment, in particular to a resource treatment process for inorganic salt hazardous wastes; and the main steps comprise feed treatment,high-temperature oxidation, waste salt refining treatment and evaporative crystallization. According to the process, the inorganic salt hazardous wastes are subjected to resource treatment through aprocess of negative pressure drying, a multilayer suspended oxidation furnace and a high-temperature rotary oxidation furnace, and compared with a traditional industrial slag salt high-temperature heat treatment process, the process can efficiently remove organic matters and effectively solve the problems of inorganic salt melting agglomeration, high-temperature refractory material corrosion and pipeline blockage caused by cooling in a pipeline during inorganic salt refining which may exist at high temperature; by using a carbamido modified bagasse adsorbent, trace organic matters remaining ina salt solution can be effectively removed, and the process of negative pressure drying and high-temperature liquefaction oxidation furnace is adopted, so that the high-temperature decomposition rateof the organic matters in the slag salt can be guaranteed and the problem of melting agglomeration can be solved.
