Abstract

Belonging to the field of sludge recycling disposal, the invention in particular relates to a plant-growing pervious concrete system for sludge recycling disposal and a preparation method thereof. The method includes: fully mixing rubble, zeolite, vermiculite, ceramsite, porous silicon dioxide microspheres, a cementing material, an acidic admixture and water, and conducting insertion tamping molding to obtain a base material I; carrying out sieving and dehydration on sludge to obtain a slurry II; fully mixing the slurry II with a permeable conditioning agent and a fluidity conditioning agent, and filling the base material I with the obtained mixture so as to obtain a base material II; fully mixing the slurry with a curing agent and a modifier, and performing curing, thus obtaining a material IV; covering the surface of the base material II with a material IV, and sowing grass seeds thereon, thus obtaining the plant-growing pervious concrete system. The invention aims at sludge recycling disposal, and realizes sludge recycling disposal. The obtained plant-growing pervious concrete system can be widely applied to in rive bank slope protection projects, road edge protection projects, and sponge city construction projects.

Description

technical field [0001] The invention belongs to the fields of sludge resource disposal, ecological concrete, environmental protection materials and permeable materials, and in particular relates to a plant-grown permeable concrete system for realizing sludge resource disposal and a preparation method thereof. Background technique [0002] Silt is a floc structure formed by the deposition of clay minerals, animal and plant humus, fine sand and other fine particles under the action of slow flowing water. For the purposes of dredging and navigation, environmental protection and water quality improvement, large-scale dredging of rivers, lakes and rivers has been carried out in various places, resulting in a large amount of silt. Ordinary sludge has the characteristics of high water content, low strength, easy muddying, high humus content, and some heavy metals exceeding agricultural standards. These characteristics lead to the treatment and disposal of sludge, which has graduall...
