Endocrine disrupting compounds can affect the hormone system in organisms. Industrial chemicals with estrogenic effects were detected in large quantities in landfill leachates. Membrane technology has proven to be an effective barrier to these substances and thus widely applied in the treatment of landfill leachate. The removal techniques under investigation are membrane bioreactors, nanofiltration, activated carbon adsorption, ozonation as well as reverse osmosis. Investigations were conducted at two different landfill leachate treatment plants with a variety of process configurations. The xenoestrogenic substances nonylphenol and bisphenol A were detected in high microg/L-ranges in raw landfill leachate. Membrane bioreactors (MBRs) were capable of removing more than 80% of the nonylphenol load. Final effluent concentrations range between 1-12 microg/L nonylphenol and 3-30 microg/L bisphenol A respectively. Reverse osmosis treatment proved to be less effective in nonylphenol and bisphenol A removal than MBR with further polishing stages like nanofiltration and activated carbon adsorption.
内分泌干扰化合物会影响生物体的激素系统。在垃圾渗滤液中大量检测到具有雌激素效应的工业化学品。膜技术已被证明是对这些物质的有效屏障，因此广泛应用于垃圾渗滤液的处理。正在研究的去除技术包括膜生物反应器、纳滤、活性炭吸附、臭氧化以及反渗透。在两个不同的具有多种工艺配置的垃圾渗滤液处理厂进行了调查。在原始垃圾渗滤液中检测到的外源性雌激素物质壬基酚和双酚A的浓度高达微克/升级别。膜生物反应器能够去除超过80%的壬基酚负荷。最终出水浓度分别在1至12微克/升壬基酚和3至30微克/升双酚A之间。事实证明，与带有纳滤和活性炭吸附等进一步精制阶段的膜生物反应器相比，反渗透处理在去除壬基酚和双酚A方面效果较差。
