Sludge curing agent for ecological planting and preparation method thereof
The invention discloses a sludge curing agent for ecological planting. The sludge curing agent comprises the following components in percentage by mass: 50-70% of modified waste concrete micro powder, 5-10% of lithium slag, 10-35% of plant fibers, 1-4% of ferrous sulfate, 5-20% of active magnesium oxide, 1-5% of super absorbent resin and 3-10% of a biological leavening agent, wherein the modified waste concrete micro powder is prepared by sorting, crushing, screening and dehydrating construction waste. According to the method, the modified waste concrete micro powder, the active magnesium oxide and the lithium slag are fully utilized to provide a weakly alkaline environment in a gradient manner, and the curing material system design and optimization means are combined, so that the sludge curing effect can be further improved on the basis of meeting the ecological planting requirements, and the method has remarkable economic and environmental benefits.
本发明公开了一种用于生态种植的淤泥固化剂，各组分及其所占质量百分比包括：改性废弃混凝土微粉50‑70％，锂渣5‑10％，植物纤维10‑35％，硫酸亚铁1‑4％，活性氧化镁5‑20％，高吸水树脂1‑5％，生物发酵剂3‑10％；其中改性废弃混凝土微粉利用建筑垃圾进行分拣、破碎、筛分和脱水处理而成。本发明充分利用改性废弃混凝土微粉、活性氧化镁和锂渣梯级提供弱碱性环境，并结合固化材料体系设计和优化手段，在满足生态种植需求的基础上，可进一步改善淤泥固化效果，具有显著的经济和环境效益。
