重庆市石柱县黄水镇水厂设计

左智敏,梁明皞,李文,姚乐,胡颖(重庆中设工程设计有限公司,重庆400023):根据水源水质老水厂工艺地形地貌特点确定了黄水镇6000m3/d新水厂的工艺流程,介绍了主要构筑物的设计参数,对比分析了场平优化设计方案设计充分利用了新旧水厂的供水量和水压,采用水泵加压与重力联合供水方式,既满足功能要求,又节约了投资运行成本:城镇水厂;常规工艺;厂区平场;水泵加压;重力供水:TU991.02:C:1673-9353(2011)02-0056-04do:i10.3969/.jissn.1673-9353.2011.02.0181项目背景,240km,63km12km,37km,1551.4m,1934m,1200m,1500m3/d,1583m,1536m,1532.40m,1535.30m,9.5km,DN50~DN250,,,3500m3/d,,,1500m3/d,6000m3/d,,2水源状况,170104m3,10km2,,,0.081m3/s,21104m3,230m,1536m1[1]1pH8.116~9/(mgL-1)7.525/(mgL-1)1.726/(mgL-1)10.420BOD5/(mgL-1)1.204/(mgL-1)0.1241.0/(mgL-1)0.0320.05/(mgL-1)0.381.0/(mgL-1)0.1661.0/(L-1)800010000/(mgL-1)0.100.3/(mgL-1)0.010.1SS/(mgL-1)11.60.11,(GB38382002),3净水工艺1km,,1561~1583m56第5卷第2期2011年4月供水技术WATERTECHNOLOGYVo.l5No.2Apr.2011,(GB57492006),114主要构筑物,1582m1532.40m,,,,0.28m/s,10mm,50mm,k1=0.75,0.21m2,6300m3/d2DN250,246mDN200,10m,67.988m,3150S78(Q=126m3/h,H=70m,=70%),2155kW,,1531.647m,1536.8m,18.2m6.6m6300m3/d3,2.8m2.7m,2.5m,0.03645m3/s,DN300,1.16m/s--,6,1.1m1.1m,3.3m,10min,35mm,3:22225mm25mm,16,4;30mm30mm,15,3;35mm35mm,14,25.4m3.3m,4.5m1.0m,2.5mm/s,0.4mm,d=30mm,L=1000mm,=60,22,4.0m4.0m,15.48m2,9.0m/h,5.12m,,300mm,0.8~1.8mm;,400mm200mm,(2~4),(4~8),(8~16)(16~25)mm,50mmABS15L/(m2s),5min,24h1.70m20%,2,12m12m4.5m,648m3,4.2m,18m9m3.6m2.1m1.5m1.2m,,,100L/h,2211,ClO29.6572011年4月左智敏,等:重庆市石柱县黄水镇水厂设计第5卷第2期m8.76m3.6m,2ClO2ClO21.0mg/L,2.0mg/L,,8~12,,,1503~1578m,1580m1578.80m,1580m6,28m1536m,,1500m3/d;1560~1578m,,,306.11m3/h,3.7km,1560m,28m,33m,3150S50B(Q=160m3/h,H=35m,=72.5%),21,,12.36m6.6m5水厂设计特点1500m3/d,,,,,,,3966.67m2,,1562~1583m1582~1583m,1583m,(1)(1)(1),1562~1575m;1580~1584m:(),1582~1583m,,20m,,,22:,,;,,,2m,,,,358第5卷第2期供水技术2011年4月32,2140m,9m9m,20m10m220m,7m2.5m143m6.5m4m993.62361.72,,,,,1580m,1500m3/d,;1578.80m,1580.00m,,3m,,,6结语,,,,,:[1][R].Emai:[e-mail]:2011-01-21努力创建节水型城市实施可持续发展592011年4月左智敏,等:重庆市石柱县黄水镇水厂设计第5卷第2期
