【摘要】：钱塘江发达的水系条件为渔业养殖提供了便利,同时养殖过程中使用的抗生素成为水源水中抗生素污染的重要来源,由于常规工艺对抗生素去除能力有限,为保障饮用水水质,采用超滤-钠滤双膜工艺进行深度处理,探讨了运行参数对组合工艺去除磺胺二甲基嘧啶的影响。结果表明:超滤通量的增加和运行时间的延长可在一定程度上影响膜污染快慢,膜污染可提高组合工艺对磺胺二甲基嘧啶的去除效果;提高回收率会降低组合工艺的处理效果,增大钠滤错流速度对组合工艺的处理效果基本没影响;纳滤运行压力和膜孔径对组合工艺处理效果影响较大,提高运行压力和减小膜孔径可提高组合工艺的处理效果。
[Abstract]:The developed water system of Qian Tang river provides convenience for fishery culture. At the same time, antibiotics used in the breeding process have become an important source of antibiotic pollution in water source. Due to the limited removal ability of antibiotics in the conventional process, in order to ensure the water quality of drinking water, the ultrafiltration and sodium filtration double membrane process is used for deep treatment, and the operating parameters are discussed. The result shows that the increase of the ultrafiltration flux and the prolongation of the running time can affect the membrane pollution to a certain extent, and the membrane fouling can improve the effect of the combination process on the removal of the sulfur, and the recovery rate will reduce the treatment effect of the combination process and increase the rate of the flow rate of the sodium filtration. The treatment effect of the combined process has no effect, and the operation pressure and the pore size of the nanofiltration have great influence on the treatment effect of the combined process. The improvement of the operation pressure and the decrease of the pore size can improve the treatment effect of the combined process.
