摘要
济南鹊华水厂以引黄调蓄水库为水源,原水存在低浊高藻高臭味等问题,水厂原有工艺难以有效处理。为适应国家《生活饮用水卫生标准》(GB 5749—2006)要求,水厂将"混凝—沉淀—过滤—液氯消毒"工艺改造为"中置式高密度沉淀—臭氧催化氧化—上向流生物活性炭吸附—V型砂滤—液氯消毒"工艺,改造后的净水工艺对有机物、臭味等特征污染物去除效果明显,出厂水水质稳定达标。
The Yellow River reservoir is used as water source of Ji＇ nan Quehua Water Treatment Plant. The raw water is characterized by low turbidity, high algae concentration, and high odor, which is difficult to remove by existing process. In order to meet the Standards of drinking water quality （GB 5749-2006）, the process of ＂coagulation-sedimentation-filtration-liquid chlorine disinfection＂ was reconstructed into ＂middle high concentration sedimentation-ozone catalytic oxidization-upward flow biological activated carbon adsorption-V type sand filter-liquid chlorine dis- infection＂ process. The new process could remove the characterized pollutants effectively, such as organic matter and odor, and the effluent water quality could meet the standards stably.
