中文摘要:

以4种 (壬基酚(4-n-NP)，双酚A (BPA)，雌二醇 (E2)、乙炔基雌二醇 (EE2) ）内分泌干扰物 (EDCs)为目标物，针对其在城市污水处理厂工艺流程中的分布与去除进行了研究，并进一步实验研究了其去除机理。所有EDCs在城市污水厂进出水中均被检出，进水中平均浓度分别为E2：64.8 ng/L，EE2：171.5 ng/L，4-n-NP：115.4 ng/L，BPA：920.7 ng/L；出水中平均浓度分别为E2：22.8 ng/L，EE2：49.9 ng/L，4-n-NP：50.9 ng/L，BPA：84.3 ng/L。污水中EDCs目标物的去除主要来自于生物处理阶段，其去除机理主要是生物降解，生物降解速率与EDCs种类及污泥类型有关。污泥吸附对EDCs的去除可产生一定的影响。

英文摘要:

Taking four endocrine-disrupting compounds (EDCs) as target substance,the paper researched the distribution and removal rate of EDCs in process of a sewage treatment plant (STP), and further investigated the mechanisms of EDCs removal. All the target compounds were detected in the influent and effluent sewages. The mean concentrations of E2, EE2, 4-n-NP and BPA in water inlet were 64.8, 171.5, 115.4, 920.7 ng/L and that in water outlet were 22.8, 49.9, 50.9, and 84.3 ng/L. The removal of target compounds from sewage is mainly attributed to the biological treatment stage in STP. The mechanism of removal is largely biodegradation, and the rate of biodegradation is related to kinds of EDCs and types of sludge.The sludge adsorption might have certain influence on the removal of EDCs.
