铁炭-混凝沉淀-生化处理强酸性染料废水的中试研究
Pilot study on treatment of strong acid dyeing wastewater with ferric/carbon microelectrolysis-coagulation sedimentation-biological process
摘要
Abstract
The ferric carbon microelectrolysis-coagulation sedimentation-hydrolytic acidification-biological contact oxidation process was used to treat dyeing wastewater containing high concentration of acid in the pilot test study.The influence of volume ratio of carbon to ferric,HRT,aeration rate on the treatment efficiency was mainly discussed in the ferric-carbon microelectrolysis unit;the influence of influent pH of wastewater,HRT on the treatment efficiency was mainly discussed in the hydrolytic acidification unit.After being treated with ferric carbon microelectrolysis and hydrolytic acidification,the biodegradability of wastewater can be improved noticeablely,meanwhile,the colour and organic pollution load can be cut down sharply,which can ensure the efficient operation of the subsequent biological contact oxidation unit,in which,the the influence of influent concentration of wastewater and HRT on the treatment efficiency was mainly discussed.After being treated by the combined process,the effluent COD and colour of water was less than 75 mg/L and 40(times),respectively.关键词
