1 概述我国属于水资源比较缺乏的国家,且水源受到污染的情况逐渐增多,给水处理工作带来更大的挑战。在复杂的水处理工艺中,过滤是其中关键的一环。积极研制和开发新的过滤介质及过滤方法是水处理研究的重要课题。纤维束滤料具有化学稳定性好、强度高、密度小、比表面积大等优点,表面丝状结构形成网形分布,具有可压缩性。纤维滤料孔隙分布比较均匀,能较好克服表面堵塞,具有滤速高、过滤周期长、水头损失增长慢等优点。重力式纤维束过滤技术与装置是一种有广泛应用前景的水处理装置。本文对影响滤床性能的主要参数孔隙率和反洗工艺进行了试验,并进行了相关测试,
1 Overview China is a relatively lack of water resources in the country, and water pollution is gradually increasing, water treatment work to bring greater challenges. In the complex water treatment process, filtration is one of the key. Actively developing and developing new filter media and filtration methods is an important issue in water treatment research. Fiber bundle filter has the advantages of good chemical stability, high strength, low density and large specific surface area. The surface filamentous structure forms a net-shaped distribution with compressibility. The pore distribution of the fiber filter is relatively uniform, which can better overcome the clogging of the surface, has the advantages of high filtration speed, long filtration period and slow growth of head loss. Gravity fiber bundle filtration technology and device is a kind of water treatment device with wide application prospect. In this paper, the main parameters affecting the performance of the filter porosity and backwashing process were tested and carried out related tests,
