混合絮凝及周进周出沉淀池工艺设计

摘要

旺隆污水处理厂二期工程中,一级处理采用混合、絮凝、沉淀池工艺.设计采用机械混合、网格反应和周进周出矩形沉淀池的优化和改良方案,能够明显改善对悬浮物及胶体有机物的处理效果,减少后续构筑物的处理负荷和处理费用.%In the second phase project of Wanglong Wastewater Treatment Plant, a combined process of mixing, flocculation and sedimentation tank was adopted for the primary treatment. It could be seen that, the modification schemes of mechanical mixing, grid reaction and rectangular peripheral-feed and peripheral takeoff sedimentation tank could significantly improve the treatment effect on suspended substance and colloidal organics, dereased the loading of the follow-up structures and reduced the cost at the same time.
