山东省夏津县自来水厂BOT项目可行性研究
|
摘要
随着夏津县经济发展以及县城规模的不断扩大,目前供水现状已经不能满足县城社会经济发展的需要,为加快夏津县经济建设步伐,保证区域经济可持续发展,拟定在县城北6km处的夏津水库旁修建净水厂一座,占地面积99.97亩。夏津水库水源为黄河水,是本工程比较理想的供水水源。
夏津县自来水厂BOT项目主要包括取水工程、净水工程、输水工程、配水工程四个部分。根据夏津县一二期供水服务范围供水量预测及核算,夏津县拟建净水厂规模一期为5万m3/d,二期为10万m3/d。
当地唯一满足工程规模的水源为夏津水库,其水源为黄河水。通过分析水库水质特性,确定取水工程改造方式,原水尽量取自水库表层以下约1.5m水层。净水厂在充分论证原水水质的前提下,对投药、混合、絮凝、沉淀、过滤、消毒、污泥处理工艺进行充分比选,提出水质安全性高、适合当地生产管理水平的工艺,即管式静态混合器+折板反应+平流沉淀+V型滤池+污泥处理的工艺路线,并通过化学处理的方法有效地保证出水的水质。
综合考虑工程沿线地质、施工条件等因素以及工程对安全性、经济性的要求,本工程设计采用玻璃钢夹砂管、球墨铸铁管和PE管。参考输配水管线定线原则,根据输配水管线方案的比选,选定输配水管线的走向并根据各段管线的流量配置管径。
本工程建成后,夏津县自来水厂BOT项目的一期供水规模为5万m3/d,供水的水质得到保证,并提高了城市供水的安全性。一期工程总投资12309万元,年制水量1825万m3,平均单位制水成本0.596元/m3。
Along with the economic development and the unceasing expansion scale of Xiajin County, the current status of water supply can’t meet the requirement of the social and economic development. In order to accelerate the economic construction speed of Xiajin County, and ensure the sustainable development of regional economy, we decide to draw up a plan of constructing water purification plant which is located in north Xiajin reservoir, covers an area of 99.97 mu. The source of Xiajin reservoir is the Yellow River water which is the ideal water source.
The water supply BOT project in Xiajin County mainly includes four parts: the water intake engineering, the water purification engineering, the water conveyance engineering, the water distribution engineering. According to the water supply prediction and calculation of the first and second phase water plant scale, Xiajin County decide to construct water treatment plant, the first period of the proposed plant scale is 50000m3/d, the second period is 100000m3/d.
The only source meeting the engineering scale is Xiajin reservoir, which source is the Yellow River water. Through analyzing the water characteristics of reservoirs, we can identify the transformation ways of the water intake engineering, and try to get the raw water from the reservoir below the surface to about 1.5m layer. Under the premise of sufficient argumentation of the raw water quality, the treatment processes include dosing, mixing, sedimentation, flocculation, disinfection, sludge treatment are comparsion and selection fully. Then, the water treatment plant proposed the treatment process of higher safety and more suitable for local production management, which includes the tubular static mixer, folding reaction of advection precipitating, V type filter and sludge treatment process, and ensured the effluent quality effectively by chemical treatment method.
After considering the engineering geology along the line, construction conditions and project on security and economy, the project design adopt GRP sand pipe, ductile iron pipe and PE pipe. After reference to water conveyance and distribution pipeline alignment principle, according to the water conveyance and distribution pipeline scheme selection, we select the water conveyance and distribution pipeline direction, and distribute pipe diameter according to the section of pipeline flow.
After the completion of the project, the first period scale of the water supply BOT project in Xiajin County is 50000m3/d, the water quality is ensured, and the city water supply safety is improved. The total investment of the first period of project is 123.09 million, manufacturing capacity is 18.25 million m3/year, the average unit cost of water production is 0.596 yuan/m3.
