River sediment dehydrating agent, river sediment dehydrating method and river sediment recycling method
The invention discloses a river sediment dehydrating agent, a river sediment dehydrating method and a river sediment recycling method, and the river sediment dehydrating agent comprises the following components in parts by weight: 20-25 parts of calcium peroxide, 12-16 parts of polyacrylamide, 15-20 parts of fly ash, 14-16 parts of aluminum chloride, 12-15 parts of sodium metasilicate and 8-27 parts of ferric chloride. According to the river sediment dehydrating agent provided by the invention, the water content of dredged sediment can be reduced to 40% or below, the sludge volume is greatly reduced, the dehydrated sludge is suitable for a river slope planting soil raw material or a roadbed filling material, the used chemical components are environment-friendly and do not corrode dehydrating equipment, the dredged sludge reduction is realized, and the cost is reduced. The ecological environment quality can be improved.
本发明公开了一种河道底泥脱水剂、河道底泥脱水方法及回收利用方法，以重量份计，所述河道底泥脱水剂包括：过氧化钙20‑25份，聚丙烯酰胺12‑16份，粉煤灰15‑20份，氯化铝14‑16份，偏硅酸钠12‑15份，氯化铁8‑27份。本发明提供的河道底泥脱水剂，疏浚底泥含水率可降低至40％以下，大幅降低了污泥体积，脱水后的污泥适用于河道边坡种植土原料或路基填筑材料，且所使用药剂成分环境友好，不会对脱水设备产生腐蚀，实现了疏浚污泥减量化，有益于生态环境质量提高。
