大连市交流岛净水厂一期项目工程设计方案

摘要

为保证大连市长兴岛临港工业区用水需求,在交流岛新建6万m3/d规模的净水厂.一期工程按3万m3/d规模建设,包括常规处理、深度处理及污泥处理工程.充分考虑原水水质、气候条件等因素,并对净水工艺进行了分析和比较,设计采用了新型的斜管加强型平流沉淀池,确保出水水质达到现行国家标准《生活饮用水卫生规范》 (GB 5749-2006)和《城市供水水质标准》(CJ/T 206-2005)的要求.%To guarantee water demand in Changxingdao Harbor Industrial Park, a new water treatment plant with the scale of 60,000 m3/d is to be constructed. The first phase is 30 000 m3/d including the conventional treatment, advanced treatment and sludge treatment project. The purification process is determined by raw water quality and local climate into account. A newly designed sedimentation tank is used to ensure drinking water quality meets the Standards for Drinking Water Quality (GB 5749-2006) and Water Quality Standards for Urban Water Supply (CJ/T 206-2005).
