摘要： A system that moves water to a vessel on a water body includes a retractable tube with water intake that descends to a selectable depth in the water body, a pump that moves water from the selectable depth through the retractable tube, an anchor assembly carrying the pump or retractable tube to the selectable depth and back again, and an indicator of the depth of the anchor assembly, pump, or water intake of the retractable tube in the water body. The anchor assembly includes a pole, a cantilever beam, a telescoping pole, a pole driving system, or a combination thereof. The system may include a gas delivery system configured to introduce a gas into the system's water flow and a mixing chamber or tube that mixes water and gas. Variations of the system provide a subset of these components, and can be combined with third-party components.

摘要： A mixing apparatus is disclosed for ponds and other shallow bodies of water. The apparatus uses air flow to entrain and move large volumes of water up and through the mixer. This movement of water creates a mixing of water from different depths within the body of water, and thus prevents, eliminates, or reduces stagnation of the water. The air flow is driven by one or more blowers, which may be mounted on the apparatus. The air from the blower is injected into the water about one to two feet below the surface. The air is injected through a series of relatively large holes positioned on opposed sides of tubing. The injected air creates water flow in sufficiently large volumes to mix the water within a shallow body of water of moderate size.

摘要： The present disclosure relates to water environment governance technology, and particularly discloses an urban river/lake water environment multi-interface governance and restoration method. The method is a multi-interface coordinated governance and restoration method based on “control for bottom, regulation for middle and governance for top”, including: “control for bottom”—controlling the emission of sediment nutritive salts and the dormancy and recovery of algae; “regulation for middle”—regulating primary productivity in a water body to inhibit the recovery of the algae; and “governance for top”—reducing nitrogen and phosphorus nutrients of an air-water interface to control the reproduction and growth of the algae. In the present disclosure, the water body governance and restoration technology based on interface coordination can effectively inhibit the outbreak of cyanobacteria and avoid extreme conditions in the ecosystem.

摘要： A method for controlling the growth of blue algae in a basin relates to the field of the restoration and protection of the natural ecology on the earth's surface. An ecological water treatment system was constructed for the basin with microorganisms, plants, animals, fillers and the like as main elements by building a novel ecological slope protection at the land-lake ecozone along the banks of the basin and planting eucalyptus in the basin water and/or on the bank of the basin, thereby effectively realizing the efficient nitrogen and phosphorus removal from the basin, controlling the spread of blue algae and improving the environmental water quality.

摘要： A liquid aeration system includes an air compressor system and a diffuser. The air compressor system includes an air intake manifold, an air compressor, and a compressor inlet line. The compressor inlet line fluidly connects the air intake manifold and the suction inlet of the air compressor. The compressor suctions air from the air intake manifold through at least the suction inlet hose. The compressor compresses the air into compressed air that is supplied to the diffuser.

摘要： A method of using magnetic influence on flow streams of liquids and gases to over excite their atoms, break existing molecular bonds, and from two oppositely charged flow streams cause immediate and permanent bonding of oppositely charged ions to create a new molecular composition. While magnetic influence is predominately responsible for the molecular reorganization produced, induced turbulence disrupts a tendency for laminar flow in the flow streams, creating more chaotic movement and molecule collisions in liquids/gases used and a more complete result. Mixing of the two oppositely charged flow streams is preferred via a venturi. Magnetic influence on flow streams can be applied more than once. Using this method with water having a molecular composition of H2O in a primary flow stream and ozone gas in a secondary flow stream, and mixing of the oppositely charged flow streams using a venturi, a new molecular composition of H2O5 can be created.
