To select an optimum treatment technology to solve the TNT red water contaminated soil problem in explosive industry， the high temperature sintering resourcing technology was developed. Contaminated soil and clay soil were mixed in a volume ratio of 4∶6， dried for 26 h in the drying section of a tunnel kiln by residual heat from the roasting section， and then roasted for 24 h in the roasting section at 1100 ℃. Sintering tail gas of the tunnel kiln was emitted into ambient air from its 43 m high funnel after treatment of desulfurization and denitrification facilities. Finished bricks were cooled down naturally out of the kiln. The featured pollutant-dinitrotoluene sulfonate in contaminated soil is completely decomposed， sintering tail gas reaches the emission standards， resource-based products meet the quality standard of building material bricks without any featured pollutant residue， and soil restoration target （the content of dinitrotoluene sulfonate in soil less than 100 mg·kg^-1） is met. The effectiveness and practicability of the high temperature sintering resourcing technology in TNT red water contaminated soil restoration was verified through engineering application.
