Design of Domestic Sewage Treatment Process in a Southern Community
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 the field of small-scale domestic sewage treatment.
