底泥净化新技术用于治理污染水体

Application of New Sediment Purification Technology to Polluted Water Body Treatment

为了有效地提高对污染水体底泥的处理效果,针对目前底泥疏浚等处置方法存在的问题,提出了一种全新的底泥净化技术,并在池州百荷公园水体综合治理中实现了工程化应用。结果表明,底泥净化技术对于污染水体底泥的处理效果显著。经过底泥净化处理系统后,实现了削减表层底泥氮磷污染物的目的,又阻挡了深层污泥氮磷污染物的释放,有效减少了水体内源性营养氮磷负荷。水质由地表水Ⅴ类提升至Ⅲ类标准,改善了水生态环境。

In order to effectively improve the treatment effect of polluted water sediment, in view of the present problems existing in the disposal methods of sediment dredging, a new kind of sediment purification technology was put forward and applied to Chizhou Baihe Park water comprehensive treat- ment. The results showed that the sediment purification technology could effectively treat polluted water sediment. The sediment purification treatment system reduced nitrogen and phosphorus pollutants in sur- face sediment, and prevented the release of nitrogen and phosphorus pollutants from deep sludge, which effectively reduced the endogenous nitrogen and phosphorus nutrition loading. Water quality was improved from the class V criteria to the class Ⅲ criteria for surface water, and the water ecological environ- ment was improved.
