Method and curing agent for rapidly curing sludge with high water content
The invention relates to a method for quickly curing high-water-content sludge and a curing agent, and the method specifically comprises the following steps: S1, simultaneously adding cationic polyacrylamide, ordinary Portland cement and steel slag into the high-water-content sludge, and quickly stirring for 5 minutes; s2, containing SAP (super absorbent polymer) particles and straw ash in a soilbag, and tightening the opening of the soilbag; s3, the geotechnical bags are put into the sludge with the high water content, and curing treatment is conducted for 28 days; the water content of the sludge can be rapidly reduced, the sludge can be used for roadbed filling or earthwork backfilling of roads and railways after being cured, and harmless and resourceful treatment can be efficiently carried out on the sludge.
本发明涉及一种对高含水率淤泥进行快速固化的方法及固化剂，具体包括以下步骤：步骤S1：将阳离子聚丙烯酰胺、普通硅酸盐水泥以及钢渣同时加入到高含水率淤泥中，快速搅拌5min；步骤S2：将高分子吸水树脂SAP颗粒以及秸秆灰盛装在土工袋内，扎紧土工袋袋口；步骤S3：将土工袋放入高含水率淤泥中，固化处理28天；本发明能够快速降低淤泥含水率，淤泥固化后可用于公路、铁路路基填筑或土方回填，高效的对淤泥进行无害化、资源化处理。
