北方地区水库水的温度浊度和藻含量,随季节或气候变化高低交替,严重影响常规供水处理工艺的处理效果浮沉
摘要、。
池工艺结合了气浮和沉淀的优势功能,可以较好地应对水质变化,其处理优势有:水力负荷高池体紧凑截留悬浮固体的效率
、、
高高水力负荷下除藻能力强出水水质优良且稳定启动迅速对原水水质和水力负荷有较强的抗冲击能力等该文基于投产
、、、、。
使用的多座浮沉池的运行参数,分析认为浮沉池工艺在处理北方地区水库水时的相关参数范围是:溶气压力为,
~ MPa
回流比为,反应时间为,表面负荷为
7 %~9 % 10~20 min 9~ m3 / m2·h。

Abstract With the seasons’or climates’change, temperature, turbidity and algal content of water in the reservoir in north China re-
gion alternated highly or low, seriously having the effects on the conventional water treatment processes. The flotation– sedimentation
basin process bined the technology advantages of the flotation and sedimentation features can respond to changes in water
quality better. And its processing advantages are as follows: a high hydraulic loading; pact pool body; h
