To optimize the pretreatment of Huanglian Jiedu decoction before ceramic membranes and verify the effect of different pretreatments in multiple model system existed in Chinese herb aqueous extract. The solution environment of Huanglian Jiedu decoction was adjusted by different pretreatments. The flux of microfiltration, transmittance of the ingredients and removal rate of common polymers were as indicators to study the effect of different solution environment It was found that flocculation had higher stable permeate flux, followed by vacuuming filtration and adjusting pH to 9. The removal rate of common polymers was comparatively high. The removal rate of protein was slightly lower than the simulated solution. The transmittance of index components were higher when adjust pH and flocculation. Membrane blocking resistance was the major factor in membrane fouling. Based on the above indicators, the effect of flocculation was comparatively significant, followed by adjusting pH to 9.
优化黄连解毒汤在陶瓷膜前的预处理工艺，验证不同预处理对中药水提液中多种模型体系的影响。通过不同预处理调节黄连解毒汤的溶液环境。以微滤通量、成分透过率和常见聚合物去除率为指标，研究不同溶液环境的影响。结果表明，絮凝法具有较高且稳定的渗透通量，其次是抽滤和调节pH至9。常见聚合物的去除率较高。蛋白质去除率略低于模拟溶液。调节pH和絮凝时指标成分的透过率较高。膜堵塞阻力是膜污染的主要因素。基于上述指标，絮凝效果较为显著，其次是调节pH至9。
