A project design example of a sewage treatment plant in an industrial park in Shandong province
The design scale of a sewage treatment plant in an industrial park in Shandong province was 2.0 × 104 m3/d,according to the characteristics of inlet water quality and discharge standards,a combined treatment process of Bardenpho+MBBR-magnetic flocculation sedimentation-denitrification deep filter-ozone catalytic oxidation,was adopted.The general idea and technical route of the said process,the technological parameters of the main structures,the design characteristics of the equipments and the project,the operation effect and the cost analysis,were introduced.The operation results showed that,the said process ran stably,the impact load resis-tance was strong,and the effluent water quality was stable up to the standard.The TN concentration in the efflu-ent water met the requirement of level A grade 1 in GB 18918-2002 Discharge standard of pollutants for mu-nicipal wastewater treatment plant,and other indicators stabilized to the class Ⅳ water standard in GB 3838-2002 Surface water environmental quality standards.
