贵阳市东郊水厂工艺设计

DESIGN OF GUIYANG EAST SUBURB WATER WORKS

贵阳东效水厂、取泉、河混合水为原水,晴天时浊度较低.雨季可增至200度以上。采用格网反应、斜管沉淀和三层滤料过滤工艺。晴天不加药运行,雨季投加聚合硫酸铁及三氯化铁。经二年多运行证明,出厂水多在3度以下,雨季最高出水浊度3.8度。

The crude water treated by Guiyang East Suburb Water Works is a mixture of spring and river water,its turbidity is relatively low during clear days,but can reach as high as 200 degrees in the rainy season.A treatment process of grating reaction,inclined tube sedimentation and tri-media filtration is adopted.During fine days,the water works goes without dosing;in the rainy season it performs with polyferric sulfate and ferric chloride.Two years' performance shows that,turbidity of the outflow is usually below 3 degrees with a maximum of 3.8 in the rainy season.
