Water-pumping aeration device for improving water quality of deepwater type water reservoir

Abstract

The invention discloses a water-pumping aeration device for improving water quality of a deepwater type water reservoir. The water-pumping aeration device comprises a mushroom-shaped flow guide outlet part, a sliding adjustment part, a non-sliding part, a main aeration device, and an anchoring pier sinking to the water bottom, which are sequentially connected from top down, wherein the mushroom-shaped flow guide outlet part is provided with a flow guide device and a flow guide hole, the sliding adjustment part at the middle part takes the measures of shock adsorption and fastening for resisting impact, the main aeration device at the lower part is additionally provided with a flow guide plate, an anchoring chain at the bottom part is sheathed with a tension spring, so that the device is prevented from being damaged or disassembled by the high-strength impact of water flow effectively, and a plurality of sections of sheathing structures which are connected in a reinforcing manner can be suitable for the automatic adjustment of the device under the condition that water level changes substantially. According to the water-pumping aeration device, the mixed oxygenation can be conductedon an upper-layer water body and a lower-layer water body of the deepwater type water reservoirs / lakes, the environment of the water body is improved, the endogenesis pollution and the algae growth can be inhibited, and the in-situ improvement of the water quality of the deepwater lakes and the deepwater reservoirs is realized, and simultaneously, the water-pumping aeration device gives consideration to the conditions of integration with other devices.

Description

technical field [0001] The invention belongs to the technical scope of micro-pollution control and treatment of water source water quality, and relates to a raw water mixing and oxygenation device, which is especially suitable for in-situ water quality improvement of water source reservoirs and lakes with large water depth, stable stratification and large water level variation. Background technique [0002] Generally, reservoirs and lakes have large water capacity and low fluidity, and many nutrients such as organic carbon, nitrogen, and phosphorus are deposited and accumulated at the bottom, providing sufficient nutrients for aquatic algae and other plankton all year round, and algae can stay in the water stably and receive light to grow in large numbers. Breeding, causing eutrophication of water bodies and affecting water quality. For deep-water source reservoirs and lakes, due to the more stable stratification of the water body, the lower water body is in anaerobic or ano...

AI Technical Summary

Problems solved by technology

For deep-water source reservoirs and lakes, the water depth is relatively large (above 60m), and the air bombs and water flow generated during the operation of the equipment will generate huge momentum and impact during the long-distance ascent process. Long-term high-intensity impact will often cause damage to the equipment. Damage or disintegration will affect the normal operation and effective function of the pumping and aeration system
