摘要
对经过电解预处理的氨基乙酸生产废水进一步采用UASB-SBBR工艺处理的可行性进行了试验研究。试验表明:在UASB启动阶段,接种高活性厌氧颗粒污泥后,在调节进水水质、合理控制进水COD质量浓度的条件下培养驯化,厌氧颗粒污泥能适应降解氨基乙酸废水水质,UASB的COD平均去除率达到60.8%;厌氧出水再经SBBR处理后,出水COD质量浓度可降低到150mg/L以下,COD平均去除率为96.1%;出水氨氮质量浓度低于25 mg/L。
In this paper, the feasibility of UASB-SBBR treatment of amino acid production wastewater pretreated by electrolytic treatment was studied. The experiments show that during the UASB start-up phase, if highly activated granular sludge is inoculated and the influent COD is eontroll properly, and after a period of domesticating, anaerobic granular sludge can be used to treat amino acid production wastewater. UASB＇s COD removal rate can reach 60.8% ; as anaerobic effluent is treated by SBBR, effluent COD can be reduced to 150 mg/L, the average COD removal rate is 96.1% and effluent ammonia is less than 25 mg/L.
