Abstract: A floating-island type artificial wetland treatment system based on a lake center platform is provided. The system includes a lake center platform, a water inflow sub-system including water inflow filled columns, a water drainage sub-system including water drainage filled columns, a water collection and distribution sub-system including water collection tanks, and a platform wetland sub-system; the water drainage filled column is located in a center of a bottom of the lake center platform; the plurality of water inflow filled columns are uniformly distributed at edges of the bottom of the lake center platform with the water drainage filled column as a center; the platform wetland sub-system is located in a center region of an upper surface of the lake center platform; and the plurality of water collection tanks are uniformly distributed at edges of the upper surface of the lake center platform with the platform wetland sub-system as a center.

Abstract: The present disclosure provides a deepwater cabin-based constructed wetland treatment system, including a cabin body, water inlet subsystems, a drainage subsystem, a micro-aeration subsystem, and a filtering scrapper subsystem. The micro-aeration subsystem includes a micro-porous aeration pipe and an air blower. The cabin body is filled with combined filler. The micro-porous aeration pipe is arranged at a bottom of the cabin body. The filtering scrapper subsystem is arranged above the combined filler. The water inlet subsystems are used for introducing wastewater to be purified onto the filtering scrapper subsystem. The filtering scrapper subsystem is used for performing filtering treatment on the wastewater to be purified to obtain filtered impurities and water after primary filtering, transporting the filtered impurities to a specified area, and introducing the water after the primary filtering onto the combined filler.

Abstract: A structure and method for three-dimensional restoration of slope soil in an abandoned ion-absorbed rare earth mining area, belonging to the field of ecological restoration technologies. The structure for three-dimensional restoration of slope soil in an abandoned ion-absorbed rare earth mining area provided by the present invention includes an ecological water-harvesting pond, ecological intercepting ditches, an improved soil layer laid on the surface of a to-be-restored slope region and a soil restoration ecological network disposed on the improved soil layer. The improved soil layer, the ecological water-harvesting pond and the ecological intercepting ditches are each provided with a combined plant synusia system.

Abstract: The present disclosure relates to the technical field of water purifying material, and in particular to a kaolin-based water purifying material, a preparation method and use thereof. The method for preparing a kaolin-based water purifying material provided by the present disclosure includes the following steps: mixing kaolin and a modifier with water, and conducting hydrothermal reaction to obtain a kaolin-based water purifying material; the modifier is an organic or inorganic modifier; the organic modifier is octadecyl trimethyl ammonium chloride (OTAC), and the inorganic modifier is one or more of polyaluminum chloride, Al2(SO4)3, Fe2(SO4)3, AlCl3 and FeCl3; the kaolin is 200-400 mesh in particle size. The water purifying material of the present disclosure enables efficient algae removal and water purification, and is safe and eco-friendly.
