Abstract[English]
The eco-friendly three-layer concrete slab for advanced filtration of urban polluted water and flood resilience provides a transformative solution to pressing urban challenges, including rainwater runoff and soil pollution. Unlike traditional impermeable concrete, which exacerbates flooding, or permeable alternatives that struggle with clogging and pollutant removal, this innovative design optimally enhances filtration and drainage. The top layer captures larger pollutants, while the middle layer employs additives like activated carbon, graphite, carbon nanofibers, and specialized aggregates (garnet, silica, basalt, granite, and dolomite) to effectively eliminate heavy metals, nitrates, arsenic, pharmaceuticals, and microplastics. The robust bottom layer, reinforced with polypropylene fibers, ensures structural integrity and durability, executing final filtration even in harsh environments. Designed for use as precast slabs and concrete covers for water channels, this advanced porous concrete facilitates efficient rainwater management and supports safe irrigation practices, thereby promoting sustainable agriculture and contributing to healthier ecosystems and resilient urban infrastructure.[French]
La présente invention concerne une dalle de béton éco-responsable à trois couches pour la filtration avancée des eaux urbaines polluées et la résilience face aux inondations apportant une solution transformatrice aux défis urbains pressants, notamment le ruissellement des eaux de pluie et la pollution des sols. Contrairement au béton imperméable traditionnel, qui aggrave les inondations, ou aux alternatives perméables qui luttent contre le colmatage et l'élimination des polluants, cette conception innovante optimise de manière idéale la filtration et le drainage. La couche supérieure capture les polluants les plus volumineux, tandis que la couche intermédiaire utilise des additifs tels que le charbon actif, le graphite, les nanofibres de carbone et des granulats spécialisés (grenat, silice, basalte, granit et dolomite) pour éliminer efficacement les métaux lourds, les nitrates, l'arsenic, les produits pharmaceutiques et les microplastiques. La couche inférieure robuste, renforcée par des fibres de polypropylène, assure l'intégrité structurale et la durabilité, exécutant une filtration finale même dans des environnements difficiles. Conçu pour être utilisé comme dalles préfabriquées et comme couvertures en béton pour les canaux d'eau, ce béton poreux avancé facilite une gestion efficace des eaux de pluie et soutient des pratiques d'irrigation sûres, favorisant ainsi une agriculture durable et contribuant à des écosystèmes plus sains et à une infrastructure urbaine résiliente.
