针对邯郸地区污水低碳源、高氮磷的水质特点,通过构建不同配合比的生态混凝土试块,采用理论分析与模型试验相结合的方法,对氮系污染物去除效果进行研究。结果表明,生态混凝土对TN、NH+4-N、NO-3-N有很好的去除作用,且孔隙率大的生态混凝土试块的去除效果较好,可见在静水条件下,生态混凝土水污染物去除效果主要受孔隙率的影响,为城市河道生态护坡工程提供了技术支持。 According to the characteristics of low carbon source and high nitrogen and phosphorus of sewage in Handan area, this paper studied the removal efficiency of nitrogenous pollutants through the construction of ecological concrete blocks with different proportions, and the combination of theoretical analysis and model test. The results show that the ecological concrete has a good removing effect on TN, NH + 4-N and NO-3-N, and the removing effect of the ecological concrete with large porosity is better. Under the condition of still water, the ecological concrete water The pollutant removal effect is mainly influenced by the porosity, which provides technical support for the ecological protection of urban rivers.
