深度处理水厂水力高程工程设计探讨

Engineering Design of Hydraulic Elevation Layout in Water Treatment Plant with Advanced Treatment

大中型新建水厂（总水头损失为8.5～10.8 m）建设时往往伴随着前臭氧预处理及深度处理（后臭氧＋活性炭）的实施,前臭氧预处理的水损（0.5～0.8 m）往往可以通过构筑物的优化布置解决;而深度处理（后臭氧＋活性炭滤池,水损约2.8～3.2 m）高程的合理设置显得至关重要。通过对山地型厂区及平原型厂区已建水厂的分析,对场地高差≥4.0 m的山地型厂区,水厂一期建设时宜在水力高程上预留深度处理所需的水头;对场地高差〈4.0 m的平原型厂区,水厂一期建设时不宜在水力高程上预留深度处理所需的水头,深度处理部分可待其实施时通过中间提升以满足其水头需要。

When large and medium new water treatment plants（total head loss of 8. 5 to 10. 8 m）are built,the ozonation pretreatment and advanced treatment（postozonation /biological activated carbon）often were accompanied. The head loss（0. 5 to 0. 8 m） of the ozonation pretreatment is often solved through the optimization layout of structures. The hydraulic elevation layout（2. 8 to 3. 2 m） of the advanced treatment is very important. Water treatment plants built at mountainous and plain areas were analyzed. The head loss of the advanced treatment should be reserved when a mountainous water treatment plant with elevation greater than or equal to 4. 0 m is built. The head loss of the advanced treatment,which can be implemented by lift pumps,should not reserved when a plain water treatment plant with elevation difference less than 4. 0 m is built.
