一种具有光催化净化效果的多孔隙水泥混凝土
摘要：
本发明提供了一种具有光催化净化效果的多孔隙水泥混凝土，其包括：通过在多孔隙水泥混凝土上面层涂抹纳米二氧化钛分散液。用于提高多孔隙水泥混凝土路面对有机污染物、氨氮污染物和磷污染物的净化效果。本发明加入纳米二氧化钛分散液后可以提高多孔隙水泥混凝土样块对雨水径流污染物的净化效果，尤其是对氨氮污染物和有机污染物的净化效果均有很大幅度提高。因此，该净化方法可以直接有效地提高多孔隙水泥混凝土的净化效果，以有效缓解径流污水的污染问题。
摘要（英）：

The invention provides a multi-pore cement concrete with photocatalytic purification effect. The upper layer of the multi-pore cement concrete is coated by nanometer titanium dioxide dispersion liquid. The purification effect of multi-pore cement concrete pavement on organic pollutant, ammonia nitrogen pollutant and phosphorus pollutant is improved. The invention can improve the purification effect of the multi-pore cement concrete sample block to the rainwater runoff pollutant, especially to the ammonia nitrogen pollutant and the organic pollutant after adding the nanometer titanium dioxide dispersion liquid, so as to greatly improve the purification effect on the ammonia nitrogen pollutant and the organic pollutant. Therefore, the purification method can directly and effectively improvethe purification effect of multi-pore cement concrete, in order to effectively alleviate the pollution problem of runoff sewage.
