摘要:
厌氧生物处理技术因其处理效率高、运行成本低而得到广泛应用，但仍然存在许多难题，如颗粒污泥钙化板结、颗粒污泥上浮流失和颗粒污泥解体破碎等，成为其工程应用的瓶颈。基于颗粒污泥、团聚体亚单位和微生物细胞等尺度，讨论了微生物细胞、胞外聚合物、内部孔隙对颗粒污泥传质功能的影响，从孔隙窄化、气体填充、无机晶体沉积、有机分子聚沉4个方面揭示了厌氧颗粒污泥孔隙堵塞的原因，提出了工艺优化、物理辅助技术和外源添加剂等对策，以缓解厌氧颗粒污泥孔隙堵塞，同时为优化厌氧生物处理工艺的运行性能提供理论依据和技术参数。
Abstract:
Anaerobic biological treatment technology has been widely used because of its high treatment efficiency and low operating cost. However, there are still many problems to be overcome, such as calcification of granular sludge, uplift and loss of granular sludge, and disintegration and fragmentation of granular sludge. These problems are the main bottlenecks that restrict the engineering application of anaerobic biological treatment technology. In this review, the effects of microbial cells, extracellular polymers, and internal pores on the mass transfer function of granular sludge are discussed from the different scales of granular sludge, agglomerated subunits and microbial cells. And the causes of pore blockage in anaerobic granular sludge are revealed from the aspects of pore narrowing, gas filling, deposition of inorganic crystals, and agglomeration and deposition of organic molecules. The countermeasures, such as process optimization, physically assisted technology, and exogenous additives are put forward to alleviate the pore blockage of anaerobic granular sludge. It provides theoretical basis and technical parameters for the optimization of the anaerobic biological treatment process.
