摘要
前期对毛皮废水进行厌氧中试处理,废水里大分子有机物得到较好的去除效果,但其对油脂、氨氮等物质没有较好的去除效果,为了探究经厌氧过程后废水中的有机物的可降解性,对厌氧处理环节后的毛皮废水进行好氧曝气处理,实验结果表明,当曝气时间为6 h时,油脂去除率即可达到64%,VFA平均去除率可达到63%以上,氨氮平均去除率可达到51%以上,在当曝气时间为12 h时,COD_(Cr)去除率即可达到40%以上,24 h时去除率可达到90.39%。中试工程的实施有力地证明了好氧系统适合处理经厌氧反应后的毛皮废水,并为以后的大规模工程设计探索了规律。
In the early part of this paper,fur wastewater by anaerobic treatment,the macromolecular organic matter in wastewater got a better removal effect,but it was no good for materials such as grease,ammonia nitrogen and other substances.In order to explore the degradability of organic matter in wastewater after anaerobic process,in this paper,the fur wastewater after anaerobic treatment was treated by aerobic aeration.The results showed that the oil,VFA,and ammonia nitrogen removal rates could reach over 64%,63%,and 51%respectively,when the aeration time is 6 h.When the aeration time is 12 h,the COD_(Cr) removal rate can reach more than 40%,and it can reach 90.39%at 24 h.The implementation of the pilot project suggested that the aerobic system was suitable for the treatment of fur wastewater after anaerobic reaction,and explored the law for the large-scale engineering design in the future.
