摘要

这项研究针对的是船舶舱底水污染这一紧迫问题，这是一种含油量很高的危险废水来源。研究采用了电氧化/气浮工艺，该工艺在去除有机物方面效果显著。研究了初始 pH 值、电流密度和流速等关键参数对去除舱底水化学需氧量（COD）和油脂（OG）的影响。初始 pH 值对化学需氧量和油脂去除率的影响微乎其微，而电流密度则通过影响阳极电化学反应显著提高了去除率。相反，流速越高，停留时间越短，去除效率越低。在电流密度为 10 mA/cm2、pH 值为 7.5、流速为 20 ml/min 的最佳条件下，取得了令人印象深刻的效果，去除了舱底水中约 80% 的 COD 和 99% 的 OG。这些发现凸显了这种方法在有效净化舱底水方面的潜力。

The investigation of parameters affecting the treatment of synthetic bilge water by continuous electrooxidation/flotation process

This study addresses the pressing issue of bilge water pollution from ships, a highly oily and hazardous wastewater source. The research employs the electrooxidation/flotation process, known for its effectiveness in organic matter removal. Key parameters, such as initial pH, current density and flow rate, were investigated for their impact on the removal of chemical oxygen demand (COD) and oil-grease (OG) from bilge water. Initial pH showed minimal effects on COD and OG removal, while current density significantly enhanced removal efficiency by influencing anodic electrochemical reactions. Conversely, higher flow rates reduced residence time and lowered removal efficiency. Optimal conditions, with a current density of 10 mA/cm², pH 7.5 and a flow rate of 20 ml/min, achieved impressive results, removing approximately 80% of COD and 99% of OG from bilge water. These findings highlight the potential of this method for effective bilge water purification.

期刊介绍： Water and Environment Journal is an internationally recognised peer reviewed Journal for the dissemination of innovations and solutions focussed on enhancing water management best practice. Water and Environment Journal is available to over 12,000 institutions with a further 7,000 copies physically distributed to the Chartered Institution of Water and Environmental Management (CIWEM) membership, comprised of environment sector professionals based across the value chain (utilities, consultancy, technology suppliers, regulators, government and NGOs). As such, the journal provides a conduit between academics and practitioners. We therefore particularly encourage contributions focussed at the interface between academia and industry, which deliver industrially impactful applied research underpinned by scientific evidence. We are keen to attract papers on a broad range of subjects including: -Water and wastewater treatment for agricultural, municipal and industrial applications -Sludge treatment including processing, storage and management -Water recycling -Urban and stormwater management -Integrated water management strategies -Water infrastructure and distribution -Climate change mitigation including management of impacts on agriculture, urban areas and infrastructure
