Beschreibung
Zusammenfassung:The ecological restoration material is prepared from sodium hexametaphosphate bentonite and a biological surfactant through a modification reaction, wherein the weight ratio of the biological surfactant to the sodium hexametaphosphate bentonite is (5-10): 100. In addition, the invention further discloses application of the ecological restoration material to restoration of contaminated soil of a refuse landfill. Compared with the prior art, the ecological restoration material has higher expansion characteristic and lower permeability characteristic. 公开了一种生态修复材料，由六偏磷酸钠膨润土与生物表面活性剂经过改性反应得到；其中，生物表面活性剂与六偏磷酸钠膨润土的重量比为(5-10)：100。此外，还公开了该生态修复材料用于垃圾填埋场污染土壤的修复。与现有技术相比，该生态修复材料表现出更高的膨胀特性和更低的渗透特性。
