【摘要】 通过边坡雨水径流试验,研究了掺加硅藻土的再生型多孔混凝土对径流污染的处治效果及植物相容性的影响。试验结果表明,随着硅藻土掺量的增加,多孔混凝土对重金属、氨氮的去除率有明显提高,综合强度与净化效果,硅藻土的合理掺量为20%。掺量硅藻土对多孔混凝土孔隙碱度有一定的改善作用,通过复掺ZS-2植生外加剂能有效降低孔隙PH值,与植物相容性较好。
【Abstract】 Through the slope runoff test, studing of regeneration of porous concrete with diatomite to runoff pollution treatment effects and the effects of plant compatibility. Test results show that, with the increase of amount of diatomite, porous concrete on heavy metals, ammonia nitrogen removal rate improved, comprehensive strength and purification, diatomite has a reasonable amount of 20%. Diatomite dosage on porosity of porous concrete alkalinity must be improved, through the mixed ZS-2 planting additive can reduce the pore PH value, with good plant compatibility.
