Application of porous ecological concrete system in remediation of heavy metal and/or nitrogen and phosphor polluted sediment
The invention discloses application of a porous ecological concrete system in remediation of heavy metal and/or nitrogen and phosphor polluted sediment. Porous ecological concrete comprises, by weight, activated coarse aggregate, cement and water according to the ratio of (4.02-5.69):1:(0.25-0.30); the activated coarse aggregate is one or any of zeolite, lava and activated carbon. In specific application, a porous ecological concrete covering layer of the activated porous ecological concrete is formed at a sediment-water interface; submerged plants are planted in the porous ecological concrete covering layer; under coaction of the porous ecological concrete covering layer and the submerged plants, internal release of the heavy metals and nitrogen and phosphorus in the sediment can be controlled effectively and stably for a long time; the porous ecological concrete covering layer helps well ensure overall structural completeness of a sediment covering layer, a good habitat is provided for the benthos, and the remediation and reconstruction of benthonic realm late in the remediation of the water body is facilitated.
