The predesign cost analysis of the industrial implementation of several advanced oxidation processes (AOPs) as the pretreatment of 1,4-dioxane-containing wastewater from the chemical manufacturing industry is herein assessed and discussed. Aiming to maximize biodegradability and minimize the generation of residues, ozonation (O₃), conductive diamond electrochemical oxidation (CDEO), and zerovalent iron-based heterogeneous photo-Fenton processes were tested. Sufficient biodegradability (≈60%) was reached by all the studied AOPs when the pretreatment was performed until obtaining a 40% removal of the chemical oxygen demand (COD). The design criteria consisted of reaching this 40% COD reduction in a unit with a treatment capacity of 43 800 m³·y^–1. Considering the limitations inherent to this type of assessment, it resulted, from the analysis of capital investment and annual operational spending, that the cost of all the assessed AOPs was about 5 €·m^–3.

不同高级氧化工艺处理化学工业中含1,4-二恶烷的废水的比较和预设计成本评估

本文评估并讨论了几种先进氧化工艺（AOP）在工业上作为化学制造行业的含1,4-二恶烷废水的预处理的预设计成本分析。为了最大程度地提高生物降解性并减少残留物的产生，进行了臭氧氧化（O ₃），导电金刚石电化学氧化（CDEO）和零价铁基异质光芬顿工艺的测试。当进行预处理直到获得40％的化学需氧量（COD）去除率时，所有研究的AOP都达到了足够的生物降解性（≈60％）。设计标准包括在处理能力为43 800 m ³ ·y ^–1的单元中达到40％的COD减少。考虑到此类评估固有的局限性，通过对资本投资和年度运营支出的分析得出，所有评估的AOP成本约为5欧元·m ^–3。
