Two lignites and two sub-bituminous coals were treated by hot water extraction (HWE) and hydrothermal treatment (HTT), and the simulated effluents were obtained. When the organic matters contained in the simulated effluents were removed by coagulation, the optimum conditions, such as coagulant dose and pH, were investigated. TOC and molecular weight of organic matters dissolved in the simulated effluents were analyzed by TOC analyzer and size exclusion chromatography (SEC). Also, the environment impacts of these effluents were evaluated by the Ames mutagenicity test. The mutagenicity of chlorinated effluents was reduced after coagulation process by use of PAC treatment.
