We investigated the effects of activated carbon, used as constructed wetlands (CWs) medium, on its ability to remove four emerging endocrine-disrupting chemicals (EDCs): bisphenol A (BPA), bisphenol F (BPF), bisphenol S (BPS) and 4-tert-butylphenol (4-tert-BP). Two types of CWs planted with common reed were constructed, one with pumice rock called normal CW and the other was amended with activated carbon (AC) called AC-CW. EDCs contaminated synthetic wastewater (5 mg/L of each) was treated by CWs for 8 weeks. AC-CW completely and sustainably removed all four EDCs (98–100%) starting immediately and continuing throughout the experiment. Removal performances of all EDCs by AC-CW were significantly higher than those by normal CW. After experiment, no BPA and BPF and very small amounts of BPS and 4-tert-BP were detected in AC. In AC-CW, final elimination step of EDCs might be biodegradation. In addition, bacterial populations on AC component of AC-CW were one–two orders higher than those on the pumice rock of normal CW. Therefore, in AC-CW, EDCs were initially adsorbed onto AC, where they could be effectively degraded by high bacterial population.

我们研究了用作人工湿地（CWs）介质的活性炭对其去除四种新兴的破坏内分泌的化学物质（EDC）的能力的影响：双酚A（BPA），双酚F（BPF），双酚S（BPS）和4-叔丁基苯酚（4-叔丁基苯酚-BP）。建造了两种用普通芦苇种植的化学武器，一种用浮石称为普通化学武器，另一种用活性炭（AC）修正，称为AC-CW。连续水处理含EDCs的合成废水（每种为5 mg / L），处理时间为8周。AC-CW立即彻底地并可持续地去除了所有四个EDC（98-100％），并在整个实验过程中继续进行。AC-CW对所有EDC的去除性能均显着高于普通CW。实验后，没有BPA和BPF，只有极少量的BPS和4-叔在交流电中检测到-BP。在AC-CW中，EDC的最终消除步骤可能是生物降解。此外，AC-CW的AC成分上的细菌数量比正常CW的浮石上的细菌数量高1-2个数量级。因此，在AC-CW中，EDC最初被吸附到AC上，在那里它们可以被大量细菌有效降解。
