摘要
采用厌氧缺氧好氧工艺流程，以生物膜作为厌氧、缺氧反应器，循环式生物流化床作为好氧反应器进行了焦化废水治理中试应用研究。应用结果表明，上述工艺流程用于焦化废水治理是可行的。当系统进水ＣＯＤＣｒ浓度小于１２００ｍｇ／Ｌ，系统水力停留时间为４４ｈ时，出水ＣＯＤＣｒ小于２５０ｍｇ／Ｌ；较高的进水ＮＨ３Ｎ浓度可严重影响ＮＨ３Ｎ去除。
A research on the pilot application of coking
wastewater treatment is conducted using the anaerobic\|anoxia\|aerobic process,taking the
biological films as the anaerobic\|anoxia reactor and a cycling biological fluidized bed as the
aerobic reactor.It has been shown by the use result that the application of the above process to
treatment of the coking wastewater is feasible.CODCr in the effluent is less than 250mg/L when
CODCr in the influent is less than 1200mg/L for the system and the resident time of the
waterpower is 44 hours.A higher concentration of NH\-3\|N in the influent has a heavy effect on
NH3\|N removal,yet it has hardly any effect on CODCr removal.
