Abstract：Coal direct liquefaction project generates a high concentration of wastewater containing sulfur,ammonia,phenol,etc.The system has high concentrations of organic pollutants,biological toxicity and has poor biodegradable properties.There is no successful wastewater treatment experience yet that we can learn from.Through the development and application of non-direct liquefied wastewater,the problem of high concentration of wastewater treatment is solved effectively.Through reclaiming sulfur,ammonia and phenol in wastewater and using the process of Advanced Oxidation Process to treat high concentration wastewater,the chemicals in the wastewater can be reclaimed and the qualified product water can be reused in power plant.This project has been a demonstration for treatment of coal direct liquefaction wastewater.
