摘要
随着经济的发展,水逐渐成为一种稀缺资源,传统的污水处理工艺(如活性污泥法)存在投资高、能耗高、运转管理要求高及处理效果受进水水质及水量波动影响较大的缺陷。渗滤工艺作为一种新型的水处理技术,其设备简单、投资低、操作管理方便、能耗低、净化效果良好,在污水处理领域有广阔的应用前景。主要介绍了土壤渗滤及人工快速渗滤工艺的污染物去除机理与效果、存在问题和解决措施。
With the development of the economy, the water resource is gradually becoming a scarce resource, the traditional method of wastewater purification （active sludge method） has embodied many disadvantages during the purification process, such as high investment, high energy-consumed, high requirement of operation and profoundly influenced by influent quality and the fluctuation of wastewater flow. As the advanced wastewater purification system, infiltration has gradually showed widely used foreground in the field of wastewater purification in terms of convenient process equipment, low investment, convenient operation and management, low energy-consumed and high process effect. This paper mainly introduces the purification mechanism and purification effect of contaminant by soil infiltration and constructed rapid infiltration system. The present problems and the measures of these systems are also discussed.
