Zusammenfassung: | The invention provides a coal gasification synthetic ammonia wastewater and hexamethylenediamine wastewater coupling treatment process, which comprises a pretreatment step, a biological treatment step, an advanced treatment step, a sludge treatment step and an odor treatment step, high COD molecules in hexamethylenediamine wastewater are hydrolyzed as a carbon source to be utilized in the process, the use of additional carbon sources is reduced, and the cost is reduced. And the denitrification biofilter and the Fenton oxidation are combined for deep treatment, so that COD and ammonia nitrogen in the wastewater can be removed more cleanly. The invention provides a coupling treatment process for synthetic ammonia wastewater prepared by coal gasification and hexamethylenediamine wastewater, which solves the problems caused by a coupling treatment process for synthetic ammonia wastewater prepared by coal gasification and hexamethylenediamine wastewater.
