  • Patent number: 12247359
    Abstract: A road network balanced drainage method aimed at reducing urban waterlogging is disclosed. According to the drainage demand, the existing intersection elevation is changed or the intersection elevation that meets the drainage requirement is designed and implemented in new construction so that the intersection drainage is distributed according to the desired proportion; the water flowing to the water accumulation position is transferred to reduce the waterlogging degree. Through the analysis of the depth of water accumulation in the whole road network, the method of water flow distribution at the intersection is used to make the precipitation flow evenly distributed in the whole road network. The method can be used for solving serious water accumulation of a certain road section, the balanced drainage of the whole road network, the technical transformation of existing intersections, and for the planned and designed roads. The method can effectively eliminate and prevent urban waterlogging.

  • Publication number: 20250026665
    Abstract: A method and device for separating and recovering heavy metal ions through membrane-forming mineralization fixation, applicable in the domain of acid wastewater treatment containing heavy metal ions. The process involves mixing composite mineral particles with heavy metal acidic wastewater, then conducting a first hydration reaction under static conditions. This leads to adsorption, precipitation, and crystallization of heavy metal ions in the wastewater via a colloidal liquid membrane, resulting in particles coated with a mineralized membrane. These particles exhibit a gap between the mineralized membrane and their core. The next step is to separate these coated particles and recover them. The preparation of composite mineral particles involves mixing sodium carbonate/sodium silicate, bentonite, carbide slag, and water, followed by a second hydration reaction and subsequent granulation, aging, and dehydration condensation. The particle sizes of both bentonite and carbide slag are maintained at ?74 m.
