摘　　要：旨在从阴离子树脂、粉末活性炭、氧化石墨烯3种常见物理吸附剂中筛选出1种针对养殖废水处理效果较好的吸附剂,并将其用于强化序批式活性污泥处理系统(SBR),探讨其在最佳投加量下对SBR处理系统出水水质及活性污泥性能影响。结果表明:粉末活性炭对养殖废水处理效果最好且用量最少,当其投加量为40 g/L时,COD、氨氮、总磷的去除率分别为78.89%、34.39%、83.66%,将其按最优投加量投加至SBR处理系统,得到的各出水指标、活性污泥指标均优于单独的SBR装置,粉末活性炭-SBR联合处理装置的MLSS、MLVSS、SV_(30)、SVI分别稳定在4.8~5.1 g/L、2.5~2.9 g/L、39%~41%、79~82 mL/g,COD、氨氮、总磷去除率最高可达92%、92%、89%。The purpose of this research is to select an adsorbent with better treatment effect for farming wastewater from three common physical adsorbents:anionic resin,powdered activated carbon,and graphene oxide,and apply it in an enhanced sequential batch activated sludge treatment system(SBR)to discuss its effect on the effluent quality and activated sludge performance of the SBR treatment system under the optimal dosage.The results show that the powdered activated carbon has the best effect on aquaculture wastewater treatment with the least amount.When the dosage is 40 g/L,the removal rates of COD,ammonia nitrogen,and total phosphorus are 78.89%,34.39%,and 83.66%,respectively.By adding to the SBR device according to the optimal dosage,the obtained effluent indicators and activated sludge indicators are all better than those of a separate SBR device.The MLSS,MLVSS,SV_(30),and SVI of the powdered activated carbon-SBR combined treatment device are respectively stable at 4.8-5.1 g/L,2.5-2.9 g/L,39%-41%,and 79-82 mL/g,and the removal rates of COD,ammonia nitrogen,and total phosphorus can reach up to 92%,92%,and 89%,respectively.
