某县城镇污水处理工程平面及高程布置分析表格案例1.1平面布置本设计根据布置原则布置平面图有以下几点注意的地方：（1）本设计地点属于亚热带季风气候，常年受东南风，并且把污泥等易发臭放于下风向，综合办公楼于上风向。（2）污水厂内主干道宽度主要设置为7m，主要构筑物间车行道为3.5m。（3）厂区构筑物尽可能分布集中、紧凑，便于管理也更够节约场地。管道布置也要尽可能达到最优布置。1.2高程布置1.2.1污水构筑物高程布置高程布置主要是分为两个部分计算，一部分是管渠的沿程损失和局部损失，另外一部分是构筑物的水头损失。经过计算，得出各管道及构筑物水头损失如下表5-1。表5-1管渠以及构筑物的水头损失序号管渠及构筑物名称流量L/s水头损失/m管径mm坡度i%流速m/s管长m沿程局部构筑物合计1计量槽到出水口2105000.00311.069511.30.02950.00880.03832计量槽0.260.2631个三通管0.50.855941个90°弯头0.3445消毒渠到计量槽2101055003500.00310.00511.06951.09131.51.090.00460.00910.00140.00276消毒渠0.330.3372个90°弯头0.3441.896382个三通管0.59滤布滤池到消毒渠2101055003500.00310.00511.06951.09136.23.740.01070.02640.00320.0079续表10出水堰0.1611滤布滤池0.200.2012混合池到滤布滤池105 3500.00511.09136.020.03050.00920.7277132个90°弯头0.34414絮凝池0.300.3015混合池到絮凝池1053500.00511.09132.30.01170.00350.3592161个90°弯头0.34417混合池0.200.2018二沉池到混合池1053500.00511.0913650.32940.09881.4162192个90°弯头0.34420二沉池出水堰0.3021二沉池0.300.3022AAO池到二沉池2301156004000.00150.00310.81350.915166.314.00.09660.0430.0290.01291.9135233个90°弯头0.344241个配水井0.525AAO池出水槽0.226AAO池0.550.5527初沉池到AAO池2101055003500.00310.00511.06951.091337.548.70.11510.24680.03450.0742.4584282个90°弯头0.344292个配水井0.5续表21初沉池出水堰0.3022初沉池0.300.3023沉砂池到初沉池1052103505000.00510.00311.09131.069512.6638.870.06420.11930.01920.03582.6145244个90°弯头0.344251个配水井0.5261个三通管0.527沉砂池0.360.3628细格栅0.280.2829泵房到细格栅1053500.00511.09131.50.00760.00230.009930粗格栅0.110.1131进水口到粗格栅21010000.00010.267428.30.00280.00090.3477321个90°弯头0.344本设计污水厂的进水管管底标高-6.5m，但由于非满流管DN1000充满度为0.30，所以进水管水位标高为-6.20，如下表所示。表5-2构筑物高程表序号管渠及构筑物名称水面上游标高（m）水面下游标高（m）管道水头损失（m）构筑物水头损失（m）1计量槽到出水口-1.9617-2.00.03832计量槽-1.7017-1.96170.263消毒渠到计量槽-0.8458-1.70170.85594消毒渠-0.5158-0.84580.335滤布滤池到消毒渠1.3805-0.51581.8963续表6滤布滤池1.58051.38050.27絮凝池到滤布滤池2.30821.58050.72778絮凝池2.60822.30820.309混合池到絮凝池2.96742.60820.359210混合池3.16742.96740.2011二沉池到混合池4.58363.16741.416212二沉池4.88364.58360.3013AAO池到二沉池6.79714.88361.913514AAO池7.34716.79710.5515初沉池到AAO池9.80557.34712.458416初沉池10.10559.80550.3017沉砂池到初沉池12.7210.10552.614518沉砂池13.0812.720.3619细格栅13.20013.080.1220泵房到细格栅13.209913.2000.009921泵房-6.32013.2099提升19.5299m22泵前格栅-6.200-6.3200.121.2.2污泥处理构筑物高程布置下表5-3是污泥构筑物的水头损失计算。表5-3污泥管渠以及构筑物的水头损失序号构筑物流量L/s管径D(mm)坡度i流速v(m/s)管长L/m沿程局部构筑物合计1初沉池0.300.302初沉池到污泥泵房4.488.962004000.000300.1440.071323.0187.040.00640.00290.00190.00092.04433个90°弯头0.34442个三通管0.505二沉池0.300.30续表
