This review reports the use of zeolites in biological processes such as anaerobic digestion, nitrification, denitrification and composting, review that has not been proposed yet. It was found that aerobic processes (activated sludge, nitrification, Anammox) use zeolites as ion-exchanger and biomass carriers in order to improve the seattlebility, the biomass growth on zeolite surface and the phosphorous removal. In the case of anaerobic digestion and composting, zeolites are mainly used with the aim of retaining inhibitors such as ammonia and heavy metals through ion-exchange. The inclusion of zeolite effect on mathematical models applied in biological processes is still an area that should be improved, including also the life cycle analysis of the processes that include zeolites. At the same time, the application of zeolites at industrial or full-scale is still very scarce in anaerobic digestion, being more common in nitrogen removal processes.

沸石在固体废物和废水生物处理过程中的应用——综述

该综述报告了沸石在厌氧消化、硝化、反硝化和堆肥等生物过程中的使用，但尚未提出综述。研究发现，好氧过程（活性污泥、硝化、厌氧氨氧化）使用沸石作为离子交换剂和生物质载体，以改善沉降性、沸石表面的生物质生长和除磷。在厌氧消化和堆肥中，沸石主要用于通过离子交换保留氨和重金属等抑制剂。将沸石效应纳入生物过程数学模型仍然是一个需要改进的领域，包括沸石过程的生命周期分析。同时，沸石在厌氧消化中的工业化或大规模应用还非常缺乏，在脱氮过程中更为常见。
