南方某小区生活污水处理工艺设计研究

Design of Domestic Sewage Treatment Process in a Southern Community

随着全球经济一体化进程的不断深入,人类所有的生活、生产活动都与水资源需求密不可分。但是在各行各业快速发展的同时,会产生大量的污废水。部分区域的污废水未经合理、有效的处理而直接排放至自然水体中,给水体环境、土壤环境等生态载体带来严重的负面影响。作为日常生活中常见的污水种类,生活污水的处理一直是水污染控制与治理的重点。生活污水的处理指标一般包括有机物、悬浮物、氨氮、总氮、总磷等。目前小型生活污水处理站一般采用一体化污水处理系统,系统中生物处理单元仍作为核心部分。本文以某小型生活污水处理项目为例,结合设计边界条件和处理目标,详细分析了该项目的污水处理工艺,并结合运行费用分析数据,从而为小型生活污水处理领域提供可参考的工程经验。

With the continuous deepening of global economic integration,the demand for water resources in all human life and production activities is inseparable.However,with the rapid development of various industries,a large amount of sewage and wastewater will be generated.In some regions,sewage and wastewater are not properly and effectively treated,and are directly discharged into natural water bodies,causing serious negative impacts on ecological carriers such as water and soil environments.As a common type of sewage in daily life,the treatment of domestic sewage has always been a key focus of water pollution control and treatment.The treatment indicators of domestic sewage generally include organic matter,suspended solids,ammonia nitrogen,total nitrogen,total phosphorus,etc.Currently,small domestic sewage treatment stations generally adopt integrated sewage treatment systems,and the biological treatment unit in the system is still the core part.This article takes a small-scale domestic sewage treatment project as an example,combines design boundary conditions and treatment objectives,analyzes the sewage treatment process in detail,and combines operating cost analysis data to provide reference engineering experience for thefield of small-scale domestic sewage treatment.
