摘要
针对抚顺大伙房水源8.16突发洪水导致原水浊度迅速升高,经过长期稳定后,大伙房水源水质特征随季节性变化明显,采用单一的超滤膜工艺无法满足出水水质达到(GB 5749-2006)的要求,在对应汛后高浊期、低温低浊期和高温高藻期的原水污染时,分别采用微絮凝超滤工艺、直接超滤工艺以及次氯酸钠预氧化超滤工艺。通过对比各工艺对浊度、有机物的去除效果,以及跨膜压差的增长速率,建立基于超滤工艺的大伙房水源季节性特征污染集成技术,为大伙房水源供给的给水处理厂提供升级改造备选方案。
The turbidity ofraw water in Fushun Dahuofang reservoir was rapidly increased because of emergency floodhappened in the reservoir on August 16. After long-term stability, Dahuofang water quality characteristics have changed significantly with the seasons, and effluent water quality cannotmeetthe requirements of Hygienic Standard for Drinking Waterwhile just using a single ultrafiltration membrane technology（GB 5749-2006）. In the corresponding period of high turbidity after flood, low temperature and turbidity, and high temperature and high algae, micro flocculation of ultrafiltration technology, direct ultrafiltration and ultrafiltration pre-oxidation of sodium hypochlorite were applied respectively. By comparing the removal efficiency of turbidity and organics with various processesand the growth rate of transmembrane pressure, integration technology on seasonal characteristics pollution of water in Dahuofang reservoir was established based on ultrafiltration process.This result provides upgrade options for water treatment plants supplied by Dahuofang reservoir.
