精选优质文档-倾情为你奉上设计某水厂的絮凝池,已知水量Q=70000m3/d=2917m3/h 1、用往复式隔板絮凝池2、选用数据:(1)廊道内流速采用六档: v1=o.5m/s,v2=o.4m/s,v3=0.35m/s,v4=o.3m/s,v5=o.25m/sv6=o.2m/s.(2)絮凝时间:T=20min(3)池内平均水深:H1=2m(4)超高:H2=0.3m(5)池数:n=2个3、计算 总容积 W=QT/60=291720/60=972m3F=W/( nH1)=972/(22)=243m2设池子宽度:B=20m池子长度:L=243/20=12.15m隔板间距按廊道流速不同分成六档:a1=Q/(3600nV1H1)=2917/(360020.52)=0.405m取 a1=0.405m 则实际流速:V1=0.46m/s取a2=0.65 则实际流速:V2=0.42m/s按上法计算得:a3=0.75m, V3=0.37m/sa4 =0.9m, V4=0
