摘要
东莞市某污水处理厂现状工程规模为20万m^(3)/d,文章以该工程中的新建三期工程为研究案例,工程规模为10万m^(3)/d。基于相关政策对污水处理厂总氮指标的逐步提升,通过对现状进水水质及其脱氮除氯工艺效率进行分析,对比同等进水水质情况下的改良A^(2)O工艺与多级AO工艺的设计,分析两者不同的设计参数、投资运维费用和生物脱氮除磷效率,总结两种工艺各自的优势及特点,为污水处理厂生化池工艺的选择提供参考。
The current project scale of a sewage treatment plant in Dongguan City is 200 000 m^(3)/d.This paper takes its newly-built phase III project as a research case,and the project scale is 100 000 m^(3)/d.Based on the gradual improvement of the total nitrogen index of the sewage treatment plant by relevant policies,through the analysis of the current influent water quality and the efficiency of nitrogen and chlorine removal process,the design of the improved A^(2)O process and the multi-stage AO process under the same influent water quality is compared.The different design parameters,investment operation and maintenance costs and biological nitrogen and phosphorus removal efficiency are analyzed,and the advantages and characteristics of the two processes are summarized,which provides reference for the selection of biochemical pool process in sewage treatment plant.
