Organic pollutants in water and wastewater have been causing serious environmental problems. The arbitrary discharge of wastewater by industries, and handling, use, and disposal constitute a means by which phenols, flame retardants (FRs), phthalates (PAEs) and other toxic organic pollutants enter the ecosystem. Moreover, these organic pollutants are not completely removed during treatment processes and might be degraded into highly toxic derivatives, which has led to their occurrence in the environment. Phenols, FRs and PAEs are thus highly toxic, carcinogenic and mutagenic, and are capable of disrupting the endocrine system. Therefore, investigation to understand the sources, pathways, behavior, toxicity and exposure to phenols, FRs and PAEs in the environment is necessary. Formation of different by-products makes it difficult to compare the efficacy of the treatment processes, most especially when other organic matters are present. Hence, high levels of phenols, FRs and PAEs removal could be attained with in-line combined treatment processes.
水和废水中的有机污染物一直在造成严重的环境问题。工业废水的任意排放以及处理、使用和处置构成了酚类、阻燃剂（FRs）、邻苯二甲酸酯（PAEs）和其他有毒有机污染物进入生态系统的一种途径。此外，这些有机污染物在处理过程中并未被完全去除，可能会降解为剧毒衍生物，这导致它们在环境中出现。因此，酚类、FRs和PAEs具有高毒性、致癌性和致突变性，并且能够扰乱内分泌系统。所以，有必要开展调查以了解环境中酚类、FRs和PAEs的来源、途径、行为、毒性和暴露情况。不同副产物的形成使得难以比较处理工艺的效果，尤其是当存在其他有机物时。因此，采用在线联合处理工艺可以实现对酚类、FRs和PAEs的高效去除。
