摘要
养殖废水一直是废水处理中的难题。针对养殖废水水质复杂且难降解的特点,研究了好氧颗粒污泥SBR工艺处理人工模拟养殖废水的可行性。在SBR工艺结合好氧颗粒污泥的基础上,采用单个周期三段进水与厌氧、好氧段交替的方式,有效的提高了反应系统抗冲击负荷能力。试验结果表明本系统对模拟养殖废水有很好的COD去除能力,而且具备了一定的脱氮除磷效果。
Aquaculture wastewater has always been a problem in wastewater treatment.Aiming at the complex and difficult degradation of aquaculture wastewater,the feasibility of aerobic granular sludge SBR process for artificially simulated aquaculture wastewater was studied.On the basis of the SBR process combined with aerobic granular sludge,the three-stage water inlet and the anaerobic and aerobic sections alternately were adopted in a single cycle,which effectively improved the anti-impact load capacity of the reaction system.The experimental results showed that the system maintained a good COD removal effect on simulated aquaculture wastewater,and had a certain effect of nitrogen and phosphorus removal.
