Planning And Research Of Sewage Collection And Treatment System In A Certain City

As a capital city of a country,a city in Africa has made great contributions to the economic development of Africa.However,in the process of urbanization,the lack of infrastructure in the city has seriously restricted the development of urban economy.The main problems are: the arbitrary discharge of solid waste,the contradiction between urban development and drainage system,the imperfect sewage collection and treatment system,and the lack of a perfect layout concept in urban planning.These problems become more acute with the development of cities.In this paper,through the investigation of a city,the collection of relevant information of city sewage collection and treatment system,taking a city as an example,through the collection of processing system optimization scheme of a city sewage,to provide practical reference for sewage infrastructure construction in the local african.The main contents and conclusions of this paper are as follows:1.Collected and consulted relevant basic data and literature materials to understand the natural profiles,drainage and sewage treatment status of a city,and put forward the existing problems of urban sewage collection and processing system.2.The planning of sewage collection system mainly focuses on drainage system and pipe network layout.Combined with the topography,rainfall,hydrology,population and water quality of a city,the suitable drainage system in this area is analyzed,and the zoning plan for sewage collection is planned.The layout scheme of sewage collection pipe network is put forward and optimized,and the planning scheme of sewage collection system suitable for a long term development of a city is selected.3.By reading the relevant literature,the theoretical research of sewage treatment technology,advocating sustainable development,as far as possible to maintain the existing resources,not to break the existing balance of the ecosystem and reference of international advanced technology,put forward the suitable process of a city sewage quality case,by comparing the optimal scheme,determine the applicable system planning scheme sewage treatment in the long-term development of a city.
