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。
For Fushun big room of water 8.16 sudden flood led to the rapid increase of turbidity of raw water, after long-term stability, the water quality characteristics of Dayuo room changes significantly with seasonal, using a single ultrafiltration membrane process can not meet the water quality (GB 5749-2006 ), The micro flocculation ultrafiltration process, the direct ultrafiltration process and the sodium hypochlorite pre-oxidation ultrafiltration process were respectively adopted in the raw water pollution corresponding to flood period, low temperature and low turbidity period and high temperature and high algae period. Through the comparison of turbidity, organic removal efficiency and the growth rate of transmembrane pressure difference, the integrated technology of seasonal characteristics of water in Dahuofang based on ultrafiltration technology was established, which provided upgrade and reconstruction for the water supply treatment plant of Dahuofu water supply Options.
