Abstract

The invention discloses a composite cross-linked structure reinforced sludge coagulation modifier. The composite cross-linked structure reinforced sludge coagulation modifier comprises, by mass, 100 parts of a structural material, 1-3 parts of a reinforcing agent, 15-20 parts of a dehydrating agent, 1-3 parts of a coagulation agent, 0.5-3.5 parts of an accelerant, 2-4 parts of a dispersing agent and 0.5-1 part of a biocide. The invention also discloses application of the composite cross-linked structure reinforced sludge coagulation modifier in sludge treatment. All the components have strictaddition and mixing sequences in the application, and the sludge treatment effect is seriously influenced by improper addition. The composite cross-linked structure reinforced sludge coagulation modifier provided by the invention has good sludge reinforcement and modification effects on sludge, is simple and convenient in application method, and easy to construct, has no secondary pollutants in the application process, has good application and popularization value, meets various application requirements of sludge recycling, and has important significance in green treatment and application of sludge.

Description

technical field [0001] The invention belongs to the technical field of sludge resource utilization, and in particular relates to a composite cross-linked structure strengthening sludge coagulation modifier and application thereof. Background technique [0002] In recent years, with the development of the economy and the urgent need for the construction of transportation facilities, operations such as river cleaning, dredging and port construction have been widely carried out. Accompanied by the need to deal with a large amount of sludge, this type of sludge often has the characteristics of high water content, poor compressibility, and low strength, and cannot be simply disposed of by dumping or landfilling; if it is not handled properly, it may also lead to Secondary pollution. Therefore, the aftermath treatment of sludge is very important. For the treatment of these silts, the research at home and abroad is more and more inclined to solidify them, which not only saves the...
