Preparation method of vegetation stone for repairing polluted riverway
The invention discloses a preparation method of vegetation stone for repairing a polluted riverway. The vegetation stone comprises the following components in percentage by mass, 30%-35% of river silt, 30%-35% of loam, 15%-20% of cement, 3%-5% of a composite curing agent and 5%-10% of a modifier. The method specifically comprises the following steps: S1, adding river silt, loam, cement, the composite curing agent and the modifier into a stirrer; stirring the materials, uniformly stirring the materials to obtain a mixture A. The beneficial effects of the preparation method are as follows: aquatic plant seeds in the vegetation stones germinate, plants grow, a large amount of pollutants in water can be adsorbed and absorbed; vegetation stone provides a good attachment environment for seed germination, riverway sludge can release part of nutrient substances for plant germination and growth, the riverway sludge is used as a raw material, the ecological benefit is high, the strength of the vegetation stone is large, the vegetation stone is stable, the porosity of the vegetation stone is high, pollutants in water can be adsorbed, and a good habitat is provided for microorganisms.
本发明公开了一种用于污染河道修复的植生石制备方法，按质量百分含量包括：河道淤泥30％‑35％、壤土30％‑35％、水泥15％‑20％、复合固化剂3％‑5％、改性剂5％‑10％，具体包括以下步骤：S1、将河道淤泥、壤土、水泥、复合固化剂以及改性剂加入搅拌机内，对上述材料进行搅拌，使得上述材料搅拌均匀得到混合物A，本发明的有益效果如下：植生石内的水生植物种子萌发，植物生长，能够大量吸附吸收水中污染物质，植生石为种子萌发提供良好的附着环境，且河道淤泥会释放部分营养物质供给植物萌发与生长，利用河道淤泥为原材料，生态效益高，植生石强度大，较为稳定，植生石孔隙率高，可吸附水中污染物质，并为微生物提供良好生境。
