摘 要:通过某污水处理厂改造提标案例,从设计角度对进水水质、处理规模、处理工艺、主体设施参数、运行状态等方面进行分析,评价各单元实际处理效果,找出设计过程容易忽视的问题。对本项目中出现的如沉砂池效率低、好氧池溶氧效率低、总氮难达标、污泥产量大等情况进行技术探讨,提出更换沉砂池类型、改变曝气方式与风机类型、调整碳氮比、增设污泥烘干设施等切实可行的改造措施和工艺流程。Through the study of an upgrading and reconstruction case of a sewage treatment plant,the influent water quality,treatment scale,treatment process,main facility parameters and operation status were analyzed from design point of view.The actual treatment effect of each unit was evaluated,and the problems easily ignored in the design process were pointed out.The low efficiency of sedimentation tank,low dissolved oxygen efficiency of aerobic tank,difficult to reach the standard of total nitrogen and large sludge production in this project were discussed.Some feasible measures and process for the reconstruction such as:changing sedimentation tank type,changing aeration mode and fan type,adjusting carbon-nitrogen ratio,adding sludge drying facilities and so on were put forward.
