摘　　要：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。Aiming at the low carbon source and high nitrogen and phosphoru sewage quality in Handan region,this paper studies the nitrogen pollutant removal effect for ecological concrete.By constructing ecological concrete briquettes with different mix proportion,it analyzes the removal efficiency of nitrogen pollutants with combination of theoretical analysis and model experiment.The experimental results show that the ecological concrete has a good removal effect on TN、NH＋4-N、NO-3-N and the effect of ecological concrete briquettes with large porosity is better.So,the removal effect of ecological concrete is mainly influenced by the porosity under hydrostatic condition.The results can provide technical support for the ecological slope protection of urban river.
