摘要
利用旋转式藻生物膜系统(RAB)处理模拟含聚废水,采用续批式运行,以PAM、黏度、COD、TN、TC、IC、TOC为指标,对比了添加共代谢N源对PAM去除效果的影响。结果显示,PAM的存在没有抑制藻类的生长;RAB系统对含聚废水中的污染物有明显去除效果,PAM的去除率最高可达(64.1±2.0)%;外加共代谢N源可以促进系统对TOC的去除,较未添加时提高约20%,可达(34.5±1.5)%。经红外光谱分析,处理前后PAM的结构发生明显变化,处理后C—N的吸收峰消失,而O—H弯曲振动和C—O伸缩振动明显增强。RAB系统可以实现含聚废水的处理,可以对其中高分子有机物进行有效的降解和吸收,具有较好的应用前景。
The rotary algae biofilm system(RAB)is used to treat simulated polymer-containing wastewater in a batch feeding approach,in which PAM,viscosity,COD,TN,TC,IC,and TOC are taken as indicators to comparatively investigate the effects of adding co-metabolic nitrogen sources on removal of PAM.Results show that PAM does not inhibit the growth of algae,and the RAB system has a significant removal effect on the pollutants in the polymer-containing wastewater with the removal rate of PAM up to 64.1%±2.0%.Adding co-metabolism nitrogen sources can promote the removal of TOC to a rate as high as 34.5%±1.5%,which is about 20% higher than that with no adding.Infrared spectroscopy analysis indicates that the structure of PAM changes obviously after the treatment including disappearing of C—N absorption peak and significant enhancement of O—H bending vibration and C—O stretching vibration.It can be concluded that the RAB system can effectively degrade and absorb high-molecular organics in polymer-containing wastewater,which implies a bright future of the RAB system in treatment of this type of wastewater.
