摘要
随着现代工业的快速发展,工业废水中难降解污染物的种类和浓度日益复杂。采用传统的物化、生化处理技术已难以达到日趋严格的排放标准。因此解决工业废水难生物降解的问题已成为化学和环境科学领域的重要研究课题。作者通过对执行一级A排放标准的城镇污水处理厂出水进行臭氧催化氧化试验,探究臭氧催化氧化作为深度处理单元对城镇污水厂二级处理出水COD指标的进一步降解能力。通过臭氧的投加量及COD指标的去除情况,摸索臭氧投加量与COD的去除比例,以期对污水处理厂的IV类水提标等工程应用提供设计依据。
With the rapid development of modern industry,the types and concentrations of refractory organic pollutants in industrial wastewater are increasing and becoming complex.Traditional physical,chemical and biochemical treatment methods are difficult to efficiently remove these pollutants and cannot meet increasingly stringent environmental standards.Therefore,solving the problem of difficult biodegradation of industrial wastewater has become an important research topic in the fields of chemistry and environmental science.This article conducts a pilot test of ozone catalytic oxidation in an urban sewage treatment plant that implements Class A emission standards to explore the ability of ozone catalytic oxidation as an advanced treatment unit to further degrade the COD index of the secondary treatment effluent from urban sewage plants.Through the dosage of ozone and the removal of COD indicators,explore the dosage of ozone and the removal ratio of COD,in order to provide design basis for engineering applications such as Class IV water standard improvement in sewage treatment plants.
