悬浮填料SBBR在污水处理厂提标改造中的应用

Application of SBBR with Filled Suspended Carrier in Upgrading of a Wastewater Treatment Plant

以南方某污水处理厂提标改造工程为例,介绍了投加悬浮填料的序批式生物膜反应器(SBBR)设计的关键技术,包括填料选择、填料缺氧流化、填料拦截与疏导、曝气系统设计、反应器设计、底泥均化、碳源利用、对预处理和后处理的要求等,这为采用SBR及其衍生工艺的污水处理厂提标改造积累了经验,拓展了悬浮填料强化生物处理技术的应用领域。

Taking a wastewater treatment upgrading project in South China for example, the key technologies in the design of sequencing batch biofilm reactor （SBBR） with filled suspended carrier were introduced, including carrier selection criteria, carrier fluidization in anoxic environment, carrier inter- ception and transportation, aeration system design, reactor design, sediment sludge homogenization, car- bon source utilization, requirements for pretreatment and post treatment and etc. It provides experiences for wastewater treatment upgrading using SBR and its derivatives, and expanded the application of sus- pended carrier processes to enhance biological treatment.
