Abstract : Fixed bed coal - gasification wastewater has the characteristics of complex composition and high concentrations of recalcitrant compounds. The research status, development trends and engineering applications were reviewed from three aspects, including physico-chemical pretreatment, biological treatment and advanced treatment, the technology mechanism, technical characteristics and application situation were highlight analyzed. It is pointed out that the rational combination of physico-chemical pretreatment, biological treatment and advanced treatment can be the development trend of treatment of coal gasification wastewater. The considering problems during selecting specific technologies were detailed.
Key words :
gasification wastewater
physico-chemical pretreatment
biological treatment
