炼钢转炉除尘废水处理工艺设计
摘要
本设计中,主要采用混凝沉淀的方法来处理除尘废水。处理构筑物主要有粗颗粒沉淀池、浓缩池、冷却塔等。该系统可在构筑物中对悬浮物进行高效的去除,使水体温度得到大幅降低。该系统具有高效,节能的特点,且工艺可靠,出水水质好。
本设计经过详细论证工艺,对工艺过程的设备和构筑物进行了参数选择、设计计算和选型。进行了平面布置、高程布置等方面的设计,污水经过处理后可作为循环冷却水继续使用。
关键词:污水处理,浓缩池,混凝沉淀
The Process Design Of Steelmaking Converter
Dedusting Wastewater Treatment
Abstract
In this design, mainly adopts the method of coagulation deposition to handle dedusting wastewater.Mainly processing structures are Coarse particle settling basin,Concentrated tank, cooling tower, etc。The system can be efficient removal of suspended solids in the structure, make the water temperature reduced greatly . The characteristics of the system has high efficiency, energy saving, and reliable technology, good effluent water quality
Through detailed demonstration of our design process, process equipment, and design of structure parameter selection, calculation and selection.Layout, vertical layout and other aspects of design,After treatment,sewage may continue to use as cooling water
Key words: sewage disposal, thickener, coagulation sedimentation
