Agricultural non-point source restoration system based on cement blanket

Abstract

The invention relates to an agricultural non-point source restoration system based on a cement blanket. The system comprises degrading bacteria and cloth, wherein the cloth is formed by interweaving aplurality of strands of warp yarns and a plurality of strands of weft yarns; cement powder is filled in a space defined by the interwoven warp yarns and weft yarns; a layer of degrading bacteria is coated onto the inner side of the cloth; the degrading bacteria can perform agricultural non-point source restoration; through the water spreading onto the surface of the top of the cloth, cement powder in the cloth can be solidified through hydration, so that the cloth is fixed to form an arc-shaped upper cover; a layer of paste is coated between the degrading bacteria and the cloth; the partiallyhydrated cement slurry is prevented from dripping onto the surface of the agricultural non-point source through the paste; the environmental-friendly function is realized; the degrading bacteria areslowly released to flow into the soil for agricultural non-point source restoration; the restoration capability of the degrading bacteria is improved.

Description

technical field [0001] The invention relates to a restoration system, in particular to an agricultural non-point source restoration system based on cement blankets. Background technique [0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil, reduce its concentration to an acceptable level, or convert toxic and harmful pollutants into harmless substances, fundamentally As mentioned above, the technical principles of contaminated soil remediation may include changing the form of pollutants in the soil or the way they combine with the soil, reducing their mobility and bioavailability in the environment, or reducing the concentration of harmful substances in the soil. . [0003] At present, due to the complexity of pollution types and the influence of various technical requirements on agricultural non-point sources, phytoremediation is the main method, and there are also leaching...

AI Technical Summary

Problems solved by technology

[0003] At present, due to the complexity of pollution types and the influence of various technical requirements on agricultural non-point sources, phytoremediation is the main method, and there are also leaching, chemical redox, and electrokinetic repairs, which can easily cause soil damage during the restoration process. Secondary pollution, agricultural non-point source repair effect is poor, the investment in research and development of repair technology and equipment is huge, and the use steps are relatively cumbersome
