Application status of in-situ expansion and upgrading technology of urban sewage treatment plant
With the rapid development of urbanization in our country,the demand of in-situ ca-pacity expansion and upgrading of sewage treatment plants has become increasingly emergence.Under the requirements of land saving and in-situ capacity expansion and upgrading,this paper an-alyzed the actual problems faced by in-situ capacity expansion and upgrading of existing water plants.In recent years,the common technology and application status of pretreatment process,bi-ochemical treatment process and advanced treatment process were summarized under the condition of no reserved land.Biochemical treatment technology was compared in the aspects of process ma-turity,application and capacity expansion.The technical decision diagram of in-situ expansion and upgrading of sewage treatment plants was proposed and implemented for existing water plants pre-cisely.
