南方某水质净化厂提标改造工程实例

An Upgrading and Reconstruction Project Example of a Southern Water Purification Plant

以南方某水质净化厂提标改造工程为例,对改造方案、运行效果、技术经济效益等进行了介绍及分析。提标改造工程对原CASS池进行改造,并新增调节池、磁混凝高效沉淀池及反硝化深床滤池等。近期运行数据表明,该厂出水水质稳定达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准及广东省《水污染物排放限值》(DB44/26-2001)第二时段一级标准的较严值标准。

Taking the upgrading and reconstruction project of a southern water purification plant as an example,the modification scheme,operation effect,technical and economic benefit and so on were introduced and analyzed.In the upgrading and reconstruction project,CASS tank was reconstructed,the new regulating tank and magnetic coagulation high efficiency sedimentation tank and denitrification deep bed filter were built.The actual operation results showed that,the effluent quality of the said water purification plant can stably meet the first level A criteria speified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB18918-2002)and the first level criteria speified in the Discharge Limits of Water Pollutants(DB44/26-2001).
