【摘要】：目前,天津开发区正在落实“十二五”规划的实施工作,在“十二五”期间,开发区供水系统的建设和发展面临了许多新的形势,淡水资源短缺和水质污染、生活饮用水水质标准提高、滨海新区被正式纳入国家发展战略等等,这就要求自来水企业必须站在更高水平上,为开发区的生产生活提供用水保障。同时,以开发区社会和经济发展规划的指标为依据,通过进行开发区“十二五”期末和远期的需水量预测可知,开发区水厂恢复一二期供水能力迫在眉睫。开发区水厂改扩建内容为水厂一二期取水工程和净水工程的改造。由于受原水水质的不确定性影响,原有设备处理工艺已达不到最初设计供水能力。此次扩建工程将在根据原水水质特点及出水水质目标,选择先进成熟可靠的水处理工艺并进行优化,做到管理方便、供水安全、优质、可靠。本工程内容包括改建现有隔板絮凝池,并新建预臭氧接触池、机械混合井、炭吸附池及紫外车间,以期做到投资经济,效果显著。工艺选择响应国家节能减排号召,同时考虑深度处理和污泥处理系统预留。经处理后本厂出水水质要求达到《生活饮用水卫生标准》(GB5749-2006)108项水质指标,项目要求采用“炭吸附池”为主体的给水处理工艺。
[Abstract]:At present, Teda is implementing the 12th Five-Year Plan. During the 12th Five-Year Plan period, the construction and development of the water supply system of the Teda are facing many new situations, such as the shortage of freshwater resources and water pollution. The improvement of drinking water quality standards and the integration of Binhai New area into the national development strategy require the tap water enterprises to stand at a higher level to provide water security for the production and life of the development zone. At the same time, based on the indicators of the social and economic development planning of the development zone, through the forecast of the water demand of the development zone at the end of the twelfth five-year plan and in the long term, it is urgent for the water works of the development zone to restore the water supply capacity of the first and second periods. The reconstruction and extension of the water plant in the development zone includes the water intake project and the water purification project in the first and second phases of the water plant. Due to the uncertainty of raw water quality, the original treatment process can not reach the original designed water supply capacity. According to the characteristics of raw water quality and the target of effluent quality, the extension project will select and optimize the advanced, mature and reliable water treatment process to ensure convenient management, safe water supply, high quality and reliable. The project includes rebuilding the existing septum flocculating tank and constructing the pre-ozone contact tank, mechanical mixing well, carbon adsorption tank and ultraviolet workshop, in order to achieve economic investment and remarkable results. Process selection responds to the national call for energy conservation and emission reduction, while considering advanced treatment and sludge treatment system reservation. After treatment, the effluent water quality of our factory is up to 108 items of GB5749-2006. The project requires the use of "carbon adsorption pool" as the main process of water supply treatment.
