Abstract

The invention relates to the field of chemicals for soil treatment, and provides a treatment agent for sludge in river channels aiming at the problem that compressive strength of sludge after solidification treatment difficultly meet the requirements of road base construction. The treatment agent comprises the following components, in parts by mass: 5-10 parts of water, 25-35 parts of Portland cement, 15-20 parts of lime, 80-90 parts of fly ash, 10-15 parts of shell powder, and 10-12 parts of eggshell powder. The invention also discloses a preparation method of the treatment agent for the sludge in the river channels. The method comprises the following steps: step 1, uniformly stirring the water and the Portland cement; step 2, adding the lime, the fly ash, the shell powder and the eggshell powder under stirring, and performing uniform mixing under stirring; and step 3, adding the remaining components, and performing uniform mixing under stirring. A solidification method for the sludgeby using the treatment agent for the sludge in the river channels comprises the following steps: step 1, removing water in the river channels; and step 2, directly adding the treatment agent for thesludge in the river channels, and excavating the treated sludge. According to the treatment agent provided by the invention, through synergistic cooperation of the above components, improvement of a dehydration rate is facilitated, the sludge can be directly excavated after being treated, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the field of chemicals for soil treatment, more specifically, it relates to a treatment agent for river sludge. Background technique [0002] At present, in the process of river channel dredging, a lot of mud and silt will be produced. These silts usually have high water content and low strength. The surrounding water environment causes secondary pollution. Therefore, it is extremely important to properly treat the sludge. [0003] The existing silt treatment is usually to drain the water in the river channel first, so that the water content of the silt drops to 40%-50%, and then excavate the silt to the open space above the embankment with an excavator, perform dehydration treatment, and then add a curing agent Stir and solidify, and then landfill the solidified silt or use it for road base construction. However, when excavating silt with traditional treatment methods, the water content in the silt is too high because the wa...
