Research on Treatment Planning for Domestic Sewage in Ecologically Sensitive Rural Areas with Leshan Town of Changchun City as an Example
The treatment of rural domestic sewage plays an important role in improving rural living environment and building a beautiful countryside.Besides,the treatment of rural domestic sewage around water sources plays a significant role in ensuring safe drinking water in urban areas.With typical villages and towns(for example,Leshan Town of Changchun City)in ecologically sensitive areas and water source protection areas as examples,investigation and analysis are performed on the sensitive factors of water source and the current situation of the region,the sewage volume is reasonably predicted and sewage collection and treatmen t facilities are arranged according to the type of rural planning and actual development situation.The results show that a differentiated treatment model should be proposed for domestic sewage in rural areas,which shall be classified into"towns,villages and areas for major projects".Rural domestic sewage should be collected in a centralized way and treated in a decentralized way.Besides,the overall objective of global governance should be highlighted,integrated planning should be made for upstream and downstream villages and towns,and the service scope of sewage treatment facilities should be optimized,to share sewage treatment facilities across regions.
