Abstract

Abstract: The principle, forms and features of biological aerated filter as well as the influencing factors of filter media, influent quality, hydraulic loading, air-water ratio and backwashing were summarized in this review. The recent research progress of biological aerated filter on the removal of various pollutants was discussed. The advantages of this process in removing SS, organic matter, ammonia and nitrogen of wastewater were described, and the disadvantages of traditional process in practical application were pointed out. This paper also introduced optimal design in structure, aeration form and operation mode of the internal circulation biological aerated filter, which could significantly reduce the nitrification performance inhibition at high organic loading. In addition, application in treatment of high concentration sewage was prospected based on introducing the advantages and research status.

Key words: wastewater, nitrification, aeration, optimal design, internal circulation biological aerated filter

摘要： 总结了曝气生物滤池的工艺原理、形式和特点以及滤料、进水水质、水力负荷、气水比、反冲洗等因素对滤池运行效果的影响, 回顾了国内外对曝气生物滤池去除各类污染物的最新研究进展, 阐述了该工艺在废水的固体悬浮物(SS)和有机物去除、硝化除氨、反硝化脱氮等方面所具备的优势, 同时指出了传统曝气生物滤池工艺在实际应用中存在的不足之处。本文针对传统滤池在较高的进水有机负荷条件下, 其硝化性能受到明显抑制的情况, 引入了一种在结构、曝气形式及运行方式上进行优化设计的曝气生物滤池工艺——内循环曝气生物滤池, 对其结构组成、运行方式以及工艺特点等作了介绍, 并指出内循环曝气生物滤池系统的硝化性能受进水有机负荷的影响明显减小, 改良后的工艺对各类污染物的去除效果均得到强化。此外, 根据内循环曝气生物滤池的研究现状及自身优点对其在处理高浓度生活污水中的应用作了展望。
