Device for improving water quality of laminated mixed oxygenated water

Abstract

The invention discloses a device for improving water quality of laminated mixed oxygenated water. The device comprises an elevating cylinder, an aerating chamber, a gas storing chamber, an air releasing pipe, a guide plate, a perforated plate, a micro-pore aerator, a powerless automatic switching device and an anchoring pier, wherein the elevating cylinder is vertically arranged in water; the aerating chamber and the gas storing chamber are formed at the middle position of a reservoir; the micro-pore aerator is arranged at a position close to the bottom of the reservoir; a full-layer mixed oxygenation function and an isothermal layer mixed oxygenation function are integrated organically; and a telescopic cylinder for adjusting the height of the device is arranged between the aerating chamber and the micro-pore aerator, so that the stability of the entire device is improved. Through improvements on a multifunctional water pumping aerator, full-layer mixed oxygenation and isothermal layer mixed oxygenation are performed respectively by using the device for improving water quality of laminated mixed oxygenated water according to the water quality improving requirement, so that the problem of water quality pollution in the reservoir can be solved at lower energy consumption, and the aim of organically unifying two functions, the water quality improving benefit and the economic benefit is fulfilled.

Description

technical field [0001] The invention relates to an oxygenation device, in particular to a layered mixing oxygenation water quality improvement device, which is suitable for mixing reservoirs and lakes with large water depth and obvious stratification phenomenon, and oxygenating the water. Background technique [0002] At present, reservoirs and lakes have gradually become the main water supply sources for large and medium-sized cities in China, and play a very important role in my country's urban water supply. However, most reservoirs have large water depth, low fluidity, and slow water renewal, which have brought some negative impacts. Due to the low mobility, many organic matter, nitrogen, phosphorus and other nutrients are deposited and accumulated in reservoirs and lakes, providing sufficient nutrition for algae and other phytoplankton. At the same time, due to the low mobility of water, the algae can stay in the surface water stably. , received sufficient light and mul...

Problems solved by technology

Continue to increase the depth, the energy consumption increases, but the mixing effect is no longer improved

[0004] In addition, for stable stratified reservoirs, the anaerobic and strongly reducing environment in the isothermal layer, especially the bottom of the isothermal layer, is the main reason for the release of pollutants in the sediment and endogenous pollution, and for deep-water reservoirs in the season when algae is low same endogenous pollution problem
