Method for sequestration and carbon sequestration of agricultural straws
The invention discloses an agricultural straw sealing and carbon sequestration method. The method comprises the following steps: step 1, straw collection; step 2, straw crushing operation; step 3, straw compression operation; step 4, drying operation; 5, curing and sealing operation; and 6, carrying out reclamation backfill operation. The method has the advantages that the agricultural straw is directly sealed and stored, the straw is derived from agricultural waste and is low in price and easy to obtain, meanwhile, CO2 trapping action is completed through respiration of the agricultural straw, energy consumption is reduced, carbon emission is reduced, the economic cost is further reduced, the straw is harmless to the environment, the chemical property of a solidified layer is stable, and the method is suitable for industrial production. In addition, the solidified layer is stable in structure, geological accidents are not prone to being caused, and sealed solid straw is greener, safer and risk-free than sealed gaseous or liquid CO2.
本发明公开了一种农业秸秆封存固碳的方法，包括以下步骤：步骤一：秸秆收集；步骤二：秸秆粉碎操作；步骤三：秸秆压缩操作；步骤四：干燥操作；步骤五：固化封存操作；步骤六：复垦回填操作。本发明的有益效果是，本发明直接封存农业秸秆，秸秆本身来源于农业废弃物，价廉易得，同时，农业秸秆自身的呼吸作用已经将CO2的捕集动作完成，故减少了能耗，降低了碳排放，进一步降低经济成本，秸秆本身对环境无害，固化层化学性质稳定，也不会对周边土壤造成污染，且固化层结构稳定，不易造成地质事故，封存固态的秸秆比封存气态或液态的CO2更加绿色安全无风险。
