A novel phenol and ammonia recovery process for coal gasification ...

Coal gasification wastewater (CGWW) is a typical toxic and refractory industrial wastewater. Here, a novel phenol and ammonia recovery process (IPE) was employed for CGWW pretreatment, and the coupled system assemble by the IPE process with A 2 /O system (IPEA 2 /O) were operated to enhance the treatment performance of CGWW. The results showed that the IPE pretreated effluent had a higher ...
