Research on the Process of a Water Purification Plant in Shenzhen Under the Background of High-density Land Development
摘要
Abstract
As a representative of super cities in China,Shenzhen is severe lacking of land resources so that the urban water purification plants and other infrastructure tend to be three-dimensional and compact design.The Shenzhen Pscare Water Purification Plant(Phase III)was constructed in model of underground water purification plant+covered park.By comparing and studying the sewage treatment process,sludge treatment process,and deodorization process schemes,it was finally determined that the"three-stage anaerobic-anoxic-oxic(AAO)"biological treatment process was adopted for sewage treatment,the"magnetic coagulation high-efficiency sedimentation tank+precision filter"process for deep treatment,and the"concentration+plate and frame deep dehydration+low-temperature thermal drying"process for sludge treatment.The entire process was biological deodorized.The effluent quality indicators can stably meet and exceed the design standards.The construction and standard operation of this plant provide a reference for the upgrading and renovation of water purification plants in super cities with high-density land development.关键词
