With the development of the industry technology, high concentrationorganic wasteliquids were made as byproducts during theproduction of chemical,electronics, pharmaceuticals, food products and leather industries. According tothe Environmental Protection Law, all these waste liquids should bedetoxified tomeet the standard before disposal.At present, the main techniques used for disposing of high concentrationorganic waste liquids are conventional biologic, physical, chemical andincinerationmethods. Among them,incineration is, compared with other methods,more complete, more in time, easier to be carried out, and with a higher heatrecovery rate. In this paper, we carry out experiments of disposing organic wasteliquids, which contain organic sulfide and organic nitrogen in a bench-scalefluidized bed.We mainly discussed theburning set, organics removal of damagedprinciples, sampling design, selection of parameters, calculation methods,analysis and comparison. We also do some research on the Destruction andRemoval Efficiency (DRE) of organic waste which contains nitrobenzene andcarbon disulfide in different temperatures and excess air. Finally we determinethe optimum conditions for the combustion of waste liquids with carbon disulfideandnitrobenzene.Test shows that the DRE of carbon disulfide and nitrobenzene has similarcharacteristics. At low temperature from 500℃to 800℃, with the increase ofexcess air, the DRE decreases step by step, meanwhile, increases slowly with theincrease of temperature. When temperature is over 850℃, DRE increases alongwith the increasing of the excess air. And at high temperature, the DRE reaches99.99% in all conditions. So we can conclude that, when burning organic wasteliquid, which contains nitrobenzene and carbon disulfide, if the temperature over900℃and the excess airis around 1.2, the DRE of organicis more than 99.99%.This paper provides theory basis to determine the temperature and excess air asorganic waste liquid isburnt.
