1) DAF
气浮工艺
1.
In order to find out the optimal operating parameters of dissolved air flotation(DAF) process,many operation parameters of DAF were studied in the pilot plant,such as pretreatment condition,the dosage of coagulant,hydraulic loading,hydrodynamic condition,recycle rate,scum period,etc.
为找出气浮(DAF)工艺的最佳运行工艺参数,对影响气浮工艺出水效果较大的预处理条件、混凝剂投量、水力负荷、水力条件、回流比、刮渣周期等运行参数做了大量的中试试验研究,发现适当的预臭氧处理可以提高UV254的去除,预加氯可以提高对浊度和藻类的去除,预加高锰酸盐可以提高对浊度、藻类、嗅味和UV254等的去除,预加粉末活性炭可以提高对有机物、色度、嗅味的去除,混凝剂投量从10 mg/L增加到50 mg/L,气浮工艺对有机物的去除率提高了30%~40%,水力负荷越高气浮出水浊度越高,回流比越大气浮出水浊度越低,气浮池过长的刮渣周期也会降低出水水质。
2.
Efficiency of treatment for low temperature and low turbidity water by DAF can be improved,but it will lead to relatively large amount of consumption of chemical and energy.
采用气浮工艺可以提高低温低浊处理效果,但投药量较大且气浮系统的能耗较高。
