The invention belongs to the technical field of recycling of electrolytic aluminum waste residues, and particularly relates to a resource utilization method of electrolytic aluminum waste residues, which comprises the following steps: 1) performing high-temperature calcination treatment on the electrolytic aluminum waste residues to obtain flue gas and furnace slag; 2) mixing the obtained slag with water, continuously blowing high-pressure air into the obtained mixture, and carrying out cavitation extraction to obtain an extract liquid; (3) filtering the obtained leaching liquor while the leaching liquor is hot to obtain filtrate and filter residues; (4) introducing the flue gas obtained in the step (1) into the filtrate, crystallizing and filtering to obtain a lithium carbonate-containing product; (5) tail gas obtained after the flue gas obtained in the step (4) is introduced into the filtrate is subjected to photocatalytic reduction to obtain CO; according to the method, complete resource utilization of the electrolytic aluminum waste residues is achieved under the condition that acid is not added, and the method has the advantages of being high in lithium recovery rate, simple in step, low in carbon, low in energy consumption, low in emission and high in safety and is quite suitable for industrial application.

This utility model relates to the field of agricultural planting technology and discloses a zoned water supply device for multi-crop strip intercropping. It includes a water outlet pile, a first water supply component mounted on the outlet pile, and a second water supply component mounted on the outlet pile. The first water supply component includes a first connecting pipe, to which a solenoid valve is fixedly connected. This zoned water supply device for multi-crop strip intercropping receives real-time crop root zone moisture data monitored by a soil moisture meter via a controller. After analysis by a smart agriculture management platform, it independently controls the opening and closing of solenoid valves one and two, adjusting the water flow of the main wheat and corn water belts respectively. Simultaneously, based on the differentiated configuration of the first and second drip irrigation belts, combined with an upward-facing anti-clogging design, it achieves precise water and fertilizer supply to the wheat and corn belts, ensuring that each crop belt is irrigated as needed.

This utility model discloses a pollution interception and purification device for river and lake ecological restoration, comprising: several sets of U-shaped seats and connecting seats installed in the river channel; adjacent U-shaped seats are connected by connecting seats; a purification slot is opened in the U-shaped opening of each U-shaped seat, and a purification plate for purifying river water is inserted into the purification slot. The purification medium of the purification plate includes a filter layer, a biological filler layer, and an adsorption layer; protective slots are opened on both sides of the purification slot in the U-shaped opening of each U-shaped seat, and protective plates for intercepting garbage and foreign objects in the river water are inserted into the protective slots. The protective plates are made of metal wire mesh. This multi-pronged approach overcomes the shortcomings of physical methods in dealing with dissolved and microbial pollution, achieving deep purification of water bodies and improving water quality.
