PROBLEM TO BE SOLVED: To provide an incineration method allowing incineration of a waste liquid, using a retention heat of a solid waste, without lowering incineration performance for the solid waste, without remaining unburnt carbon, CO or the like in combustion exhaust gas, and without generating a toxic product, when treating the waste liquid of a low calorific value in an incineration process for the solid waste. SOLUTION: In this incineration disposal method for the waste liquid, an evaporation decomposition means for the waste liquid is constituted of a first treatment process capable of feeding the waste liquid into a rotary kiln maintained at 800°C or more under reductive atmosphere of a furnace inside to be atomization-incinerated, and a second treatment process capable of feeding the waste liquid into a kiln furnace end fixing hood 41 and a secondary combustion furnace 49 for burning inflammable exhaust gas from the first process to be atomization-incinerated, in the gasification rotary kiln 36 for combustion-gasifying partially the solid waste. The feed of the waste liquid is carried out by single or combination of a waste liquid injection port of a waste feed hopper 31, a waste liquid spray nozzle 52 of a furnace front fixing hood 37, a waste liquid spray nozzle 52 of the furnace end fixing hood 41, and a waste liquid spray nozzle 53 of a secondary combustion furnace wall.
