Sludge curing material based on cement-based carbon dioxide foam as well as sludge curing method and application thereof
The invention provides a sludge curing material based on cement-based carbon dioxide foam. The sludge curing material comprises the following components in percentage by mass: 23-37% of sludge, 30-41% of fly ash and 31-36% of cement-based carbon dioxide foam, wherein 31%-36% of the cement-based carbon dioxide foam is prepared from 20%-25% of cement, 0.7%-0.9% of a foaming agent, 0.85%-0.95% of a foam stabilizer and 8%-12% of water. The invention further discloses a sludge curing method and application. Source substances which cause two environmental problems at present, namely carbon dioxide greenhouse gas and dredged sediment in lakes and oceans, are fully utilized, the foaming agent and the foam stabilizer are creatively utilized to form foam from carbon dioxide, the foam, cement and fly ash form composite slurry, the composite slurry serves as a curing agent, and the dredged sludge is solidified by using the curing agent.
本发明提供了一种基于水泥基二氧化碳泡沫的淤泥固化料，包括以下质量分数的组分：23‑37％的淤泥、30‑41％的粉煤灰和31‑36％的水泥基二氧化碳泡沫；其中，31‑36％的水泥基二氧化碳泡沫中包括20‑25％的水泥、0.7‑0.9％的发泡剂、0.85‑0.95％的稳泡剂和8‑12％的水。本发明还公开了淤泥固化方法和应用。本发明充分利用现如今引起两大环境问题的来源物，分别是二氧化碳温室气体和湖泊海洋中的疏浚底泥，本发明创新性地利用发泡剂和稳泡剂将二氧化碳形成泡沫，将其与水泥和粉煤灰形成复合浆液，该复合浆液作为一种固化剂，并利用其来固化疏浚淤泥。
