大面积、大阻力配水系统普通快滤池改建为三层滤料滤池的关键是配水系统的改造,本文通过对大阻力、中阻力配水系统模型现场对比试验的分析研究,说明只要池体高度、过滤水头满足要求,保持原有的大阻力配水系统不变,改建是可行的。
The key to rebuilding a large-area, large-resistance water distribution system from a common fast filter to a three-layer filter is the reformation of the water distribution system. This article analyzes the field comparison test of the large-resistance and middle-resistance water distribution system models, and shows that only the height of the tank is required. The filter head meets the requirements and the original large resistance water distribution system remains unchanged. Modification is feasible.
