摘 要
随着社会发展,生活居民生活用水标准日益提高。为满足人口增长和城市发展需求,本设计为长春市新城区给水工艺设计,根据相关设计手册和规范,设计处理工艺相关设备和构筑物,使出水水质达到国家二类标准,并满足日供水量11×104m3/d。
整个工程包括两大部分: 净水工程、供水工程。
净水工程的设计主要包括净水厂的设计计算。
供水工程的设计内容包括二泵站的相关计算。
净水厂的设计包括净水厂的位置选择、水处理工艺流程的确定、处理构筑物的设计计算以及水厂的平面和高程布置。
通过技术经济比较,考虑水厂后期发展和环保等问题之后,确定净水厂的工艺流程选用方案:
原水→一级泵站→机械混合→折板絮凝池→斜管沉淀池→双阀滤池→清水池→吸水井→二级泵站→用户
关键字:折板絮凝 ; 机械混合 ; 斜管沉淀池 ; 双阀滤池
Process Design of Water Supply Engineering for New urban In changchun City in JiLin Province
Abstract
With the social development,and the living warter standards rising . To meet the needs of population growth and urban development, the design process for the design of water supply in Changchun new City, according to the relevant design manuals and specifications, design treatment technology related equipment and structures, resorted to the national second-class water quality standards and meet the daily water supply volume of 11 × 104m3 / d.
The project main includes two parts: water works, water supply projects.
Design of the project include water purification plant design and calculation.
Water supply pumping station designs include the double Valve Filter
Water treatment plant design, including the location of water purification plant selection, water treatment process to determine, process design and calculation of structures and layout of water and elevation plane.
Through technical and economic comparison, after consider water plant development and environmental protection issues , the process used to determine the next water program:
Raw water →Mechanical mixer→Folded plate flocculator→Sedimentation Pond →Double Valve Filter →Clear pool→Water wells→ Users
Keywords: Folding flocculation;Mechanical mixer; and Sedimentation;Double valve filter
