High-water-content dredged sludge curing agent as well as preparation method and application thereof
The invention discloses a high-water-content dredged sludge curing agent as well as a preparation method and application thereof. The curing agent is prepared from the following raw materials: industrial steel slag, a waste incineration bottom slag mixture, sodium phosphate, straw ash and lime. During preparation, the waste incineration bottom slag and the waste incineration bottom slag ground powder are mixed to obtain a waste incineration bottom slag mixture, the straw ash and the industrial steel slag are mixed and subjected to ball milling to obtain a mixture of the straw ash ground powder and the industrial steel slag ground powder, and finally the raw materials are mixed according to the proportion to prepare the curing agent. The waste is adopted as the raw material, resource utilization of the waste is achieved, the prepared curing agent can effectively cure the dredged sludge, the water content of the dredged sludge is reduced, the low-strength characteristic of the dredged sludge is improved, the dredged sludge can be used as a filling material after being cured, and the purposes of treating waste with waste and protecting the environment are achieved.
本发明公开了一种高含水率疏浚淤泥固化剂及其制备方法与应用，其中固化剂的原料包括工业钢渣、垃圾焚烧底渣混合物、磷酸钠、秸秆灰和石灰；制备时，将垃圾焚烧底渣与垃圾焚烧底渣磨细粉混合获得垃圾焚烧底渣混合物，将秸秆灰和工业钢渣混合球磨获得秸秆灰磨细粉和工业钢渣磨细粉的混合物，最后将各原料按配比混合制得固化剂。本发明采用废弃物为原料，实现废弃物的资源化利用，所制备的固化剂能够有效固化疏浚淤泥，降低疏浚淤泥的含水率，改善疏浚淤泥的低强度特性，疏浚淤泥经固化处理后可以用作填土材料，实现以废制废、保护环境的目的。
