The Research On Sewage Treatment Project And The Drainage System Optimization Of Lan Tian

In recent years,the economic construction of Lantian county has developed rapidly.However,the construction of the drainage system in this town is obviously backward.The city drainage pipeline laying early for rainwater and sewage pipes,has the characteristics of low design standard and small diameter,and the sewage treatment facilities are not perfect which cause the sewage collection rate is low;the majority of Industrial Parksdon’t have sewage pipes,and sewage mostly direct drainage confluence on nearby terrain into the Bahe River,causing serious pollution of the river water.According to the specific problems of Lantian County,we field reconnaissance and get access to large amounts of data,analysising of the drainage system and sewage treatment project of the current situation and existing problems,discussesing the optimization scheme and improvement measures.The main contents of this paper:1 、 According to relevant information and understanding through field reconnaissance,we know about the natural and geographical conditions of Lantian County.Combined with the overall plan of the county,the present situation of the drainage system and sewage treatment engineering is analyzed,and the existing problems in the original planning are put forward.2、The optimization scheme of drainage system construction in Lantian county is determined,and the drainage system in Lantian county is determined by the system of rain and sewage diversion.For the optimization design of rainwater and sewage system,mainly from the aspects of drainage system selection,pipe network layout and pipe selection and so on,aiming at the optimization of the rainwater system and sewage system in the county,the optimization plan of drainage system is put forward.In addition,in order to rationalize the utilization of water resources,the resource utilization of rainwater and its technology are especially put forward.3、According to the scale of Lantian wastewater treatment plant transformation,we determined the reasonable inlet and outlet water quality,and compared the process plan of sewage and sludge to determine the final process of sewage treatment and reconstruction project.
