本文提出了新型均匀一非均匀滤料双层滤池,并与普通双层滤料滤池进行了对比试验研究。在高速过滤下,对杂质在滤层中的分布规律、过滤水头损失变化规律、Re、η的关系、反洗强度与反冼膨胀率间的关系等进行了探讨。对川棉一厂上水站均匀-非均匀双层滤池运行结果作了初步分析。 This paper presents a new type of uniform and non-uniform filter double filter, and compared with the ordinary double filter media. Under high-speed filtration, the distribution of impurities in the filter layer, the change law of filter head loss, the relationship between Re, η, the relationship between backwash strength and anti-tank expansion rate were discussed. A preliminary analysis of the results of the uniform-non-uniform double-layer filter at the Sheung Shui No. 1 Plant Sheung Shui Station was conducted.
