Three alternative procedures were worked out for disposal of waste liquor from production of 2,5-dichlorodisultanilic acid [CAS No. 88-50-6]. This liquor is a hazardous liquid waste which, if discharged into a wastewater treatment plant without any treatment, inhibits processes of biological treatment. The first alternative utilizes stabilization/solidification technology by using fluidized-bed combustion ash. The second alternative consists in treating the liquor in a flow-through column packed with active carbon black as an adsorbent and discharging of the treated liquor, which already displays an acceptable chemical oxygen demand level after removal of organic pollutants by adsorption, into a wastewater treatment plant. The third alternative comprises of passing the waste liquor through the column with active carbon black and stabilization/solidification of the treated liquor by fluidized bed combustion ash. Efficiency of the liquor disposal in cases of stabilization/solidification was evaluated by determining dissolved organic carbon content, conductivity, pH, and ecotoxicity of test specimens' leachates. From results it follows that the proposed procedures represent efficient disposal of given liquid waste.
