个旧市松矿水厂穿孔旋流絮凝池提升改造
|
摘要
国家新的饮用水卫生标准已全面实施,要求出厂水浊度小于1 NTU,许多水厂采用的常规处理工艺出水水质已不能满足新标准要求。因此,已建运行水质不达标的水厂需寻找有效的措施对现有工艺进行提升改造,提高出水水质,确保水厂出厂水水质达到新标准的要求。个旧市松矿水厂运行年代已久,沉淀池出水效果差,出厂水水质不满足《生活饮用水卫生标准》(GB 5749—2006)要求的浊度指标。该工程根据微涡流絮凝理论,结合网格絮凝池絮凝效果好的特点,将厂区内现状已建穿孔旋流絮凝池结构提升改造成一种新的絮凝池-微涡流絮凝池,结合两种絮凝池的优点,增强絮凝效果,提高松矿水厂出水水质。
The country's new drinking water hygiene standard has been fully implemented, requiring effluent turbidity to be less than 1 NTU, but water quality of lots of water treatment plants(WTPs) can not reach the new standard with conventional standards.In order to ensure that water quality of the waterworks can reach the new standard, it is necessary to look for effective measures to upgrade and transform the existing processes for these water treatment plants, and then improve the quality of the effluent. Songkuang WTP of Gejiu City has been operated for a long time, the treatment quality of the sedimentation tank is poor, the quality of effluent can not reach the requirements of turbidity index of Sanitary Standards for Drinking Water(GB 5749—2006). According to the theory of micro-eddy flocculation and good flocculation effect of grid flocculation pool, the project upgrades existed perforated swirl flocculation tank into a new flocculation tank-micro vortex flocculation tank. Combining the advantages of two flocculation tanks, flocculation effect can be enhanced, and the quality of effluent of Songkuang WTP can be improved.
