Abstract

The purpose of the present study was to adapt the activated sludge model No. 3 (ASM3) to the characteristics of oily industrial wastewater, determining the utmost significant and appropriate kinetic as well as stoichiometric parameters. An oily industrial wastewater treatment system was simulated to assess ASM3 validation and perform sensitivity analysis using the STOAT program. The obtained results revealed that the ASM3 model, which was calibrated after adding the Arrhenius equation into consideration, provided strong correlations with the analytical results of chemical oxygen demand (COD), total suspended solids (TSS), mixed liquor volatile suspended solids (MLVSS) and total suspended solids in the return activated sludge flow (TSS in RAS) concentrations. The values of modelled effluent COD and TSS are very close to those corresponding real values of the treated wastewater by a difference of between 0.5% and 1.5%. Thus, this model becomes successful in representing oily industrial wastewater treatment as a new trend added to the traditional modelling of sewage treatment.

应用3号活性污泥模型评价含油工业废水处理系统的性能

本研究的目的是使3号活性污泥模型(ASM3)适应含油工业废水的特点，确定最重要和最合适的动力学和化学计量参数。模拟一个含油工业废水处理系统，评估ASM3的有效性，并使用STOAT程序进行敏感性分析。结果表明，考虑Arrhenius方程校正后的ASM3模型与化学需氧量(COD)、总悬浮固体(TSS)、混合液挥发性悬浮固体(MLVSS)和回流活性污泥流中总悬浮固体(RAS中的TSS)浓度分析结果具有较强的相关性。模拟出水COD和TSS值与处理后废水的实际值非常接近，相差在0.5%和1.5%之间。因此，该模型作为传统污水处理模型的新趋势，成功地代表了含油工业废水的处理。

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
