晋北严寒地区污水处理厂准Ⅴ类提标改造工程设计

Design of the Upgrading and Reconstruction for Pre-Standard Ⅴ Sewage Treatment Plant in Cold Area of North Shanxi Province

经技术论证和经济必选,确定将现有工艺“初沉池+AAO+水力混合+折板絮凝+斜板沉淀+D型滤池”改造为“改良AAO+机械混合+机械絮凝+倒Ⅴ斜板沉淀+滤布滤池”.改造完毕后,出水稳定达到设计要求,本工程设计为设有初沉池的污水厂提标改造提供了借鉴意义.

After technical demonstration and economic selection, it is determined that the existing process "primary settling tank+AAO hydraulic mixed+folding plate flocculation+inclined plate sedimentation+D type filter" is transformed into "improved AAO+mechanical mixing +machinery flocculation+ inverted Ⅴ inclined plate sedimentation+ filter cloth filter". After the transformation, the effluent reaches the design requirements stably, and the design of this project provides reference significance for the upgrading of wastewater treatment plant with primary settling tank.
