Abstract

The invention discloses composite aggregate planting concrete with a decontamination function. The aggregate planting concrete with the decontamination function comprises, by mass, 17%-31% of cement, 1%-4% of zeolite powder, 2%-3% of water, 12%-62% of rubble and 15%-52% of ceramsite. A preparation method of the planting concrete comprises the following steps that the weighed ceramsite is soaked in water for 30 minutes to 60 minutes, and unnecessary water is filtered out naturally; the weighed rubble, the weighed cement, the weighed zeolite powder and the wet ceramsite are placed in a stirring machine and stirred for one minute; then, the water is added while stirring is conducted; the concrete is poured out after being stirred to be uniform; the concrete is obtained after being molded and cured for 28 days. The planting concrete has the advantages of being high in porosity and good in water permeation effect and has a significant adsorbing effect on SS, COD, TP, Pb, Zn and the like; meanwhile, plants rooting in gaps of the concrete can also absorb elements beneficial to growth of the plants, and double benefits are achieved.

Description

technical field [0001] The invention relates to planting concrete, in particular to a novel planting concrete with decontamination function and a preparation method thereof. Background technique [0002] While my country's urbanization is booming, the disturbance and damage to the ecosystem are also increasing. Frequent industrial production, traffic activities, and dumping of garbage lead to the accumulation of a large amount of suspended particulate matter, heavy metals, nutrients, and organic matter on the surface. When precipitation forms surface runoff, these harmful substances are entrained and discharged into the water body or soil. That is to cause the deterioration of the water quality of the receiving water body, the destruction of the aquatic ecology, and the heavy metal pollution of the surrounding soil. [0003] In order to improve the water ecosystem, on-site treatment of surface runoff pollution, as an efficient and convenient means, has received more and mor...
