摘要:

为了处理多喷嘴对置式水煤浆加压气化装置产生的废水,配套建设以改良型间歇式生物脱氮活性污泥法(A/SBR+EM)为核心技术的废水处理装置,详细介绍了气化废水处理工艺流程及工艺特点。通过1年多的实际运行,废水处理装置出水水质非常稳定,处理后的废水可全部回用于内部循环水系统。

Abstract:

In order to treat wastewater from multi-nozzle opposed coal-water slurry pressurized gasification unit, a supporting wastewater treatment unit is constructed which adopts modified batch activated sludge process with biological nitrogen removal as core technology, details of process flow sheet and process feature of the gasification wastewater treatment process are described. Through actual operation for more than 1 year, the effluent quality of wastewater treatment unit is very stable, all of the treated wastewater can be reused in internal water circulation system.
