三级生物接触氧化在高层建筑污水处理改造工程中的应用

Application of three stage bio-contact oxidation in reconstruction of wastewater treatment for high-rise building

某高层建筑已完成污水处理装置土建部分的施工,为达标排放,提出改造方案。经方案比较,将原单级接触氧化法改为三级接触氧化法,将原鼓风曝气改为潜水曝气,增加污泥外循环回流及清水池和排水泵,以强化系统脱氮效果,保证出水顺利排放。同时,介绍了各处理单元的设计参数,分析了运行费用和投资,以供同类工程参考。

In order to achieve discharge standard of the constructed wastewater treatment equipment in certain highrise building, the plan for reconstruction is provided. The single contact oxidation process in the primary plan is rebuilt to the threestage contact oxidation process and the blow aeration in the primary plane is replaced by the underwater jet aeration. The sludge outside recirculation return capacity, clean water tanks, and discharge pumps are increased for raising the effect of the denitrification and discharging at outlet successfully. At the same time, the design data of the treatment unit is introduced. The project run and investment are introduced, the project offers a reference to treat the similar wastewater
