目的:研究伴生物质对何首乌中药水提液微滤过程的影响.方法:从物理化学参数、有效成分膜透过率、高分子膜截留率及特征指纹图谱多角度分析不同压力、流速及膜孔径条件下微滤变化规律,并探讨不同条件下微滤过程中膜污染机理.结果:微滤精制前后,电导率与浊度变化显著降低,pH与黏度变化较小;高分子截留率随膜孔径增大而降低,随压力、流速增大而增大;指标成分透过率较为显著.以上不同条件下各微滤过程,通量均呈缓慢降低趋势、膜污染阻力均呈缓慢增加趋势.结论:何首乌中高分子等伴生物质对膜过程有很大的影响.

一、概述本篇所指固废包括:生活垃圾、污泥、畜禽粪便、秸秆、焚烧灰渣、毒土、尾菜、尾矿等.固废筒仓可以使污染物与外界环境隔绝,同时还是一个巨型生物发酵反应器,较长时间储存可以使有机固废腐熟稳定.因此将固废装入筒仓后,人们就掌握了控制和消灭污染的主动权.
