Intelligent micro-nano bubble generating device for black and odorous water body treatment

Abstract

The invention relates to an intelligent micro-nano bubble generating device for black and odorous water body treatment. The intelligent micro-nano bubble generating device comprises a submersible pump, a bubble device, a nano bubble generating tank, a nano aeration head, a water quality detector and a remote data transmission control box, wherein the submersible pump is connected with the bubble device, the bubble device comprises a gas ejection bubble generating device and a centrifugal pump, the gas ejection bubble generating device and the centrifugal pump are in fluid communication and form circulation, output gas-liquid mixed fluid enters the nano bubble generating tank, the nano aeration head is arranged in water needing to be treated and connected with the outlet end of the nano bubble generating tank, and the water quality detector monitors the dissolved oxygen and ammonia nitrogen concentration in real time. Compared with traditional aeration, micro-nano bubbles formed by the device provided by the invention have the advantages of long retention time, large gas-liquid contact area and high gas-liquid mass transfer speed in a treated water body, the oxygenation capacity on the water body is improved, the problems of black odor, bottom mud floating and the like caused by oxygen deficit of the water body can be effectively solved, and the device can realize green, low-carbon and efficient operation.

Description

technical field [0001] The invention relates to the field of micro-nano aeration, in particular to an intelligent micro-nano bubble generating device for treating black and odorous water bodies. Background technique [0002] At present, the number of black and odorous water bodies in rural China is innumerable and widely distributed. Compared with urban black and odorous water bodies, which are concentrated and contiguously distributed, rural black and odorous water bodies are relatively scattered. The treatment of black and odorous water bodies in rural areas is an important task in the revitalization of rural ecology and the construction of beautiful and livable villages. In July 2019, the Ministry of Ecology and Environment and other ministries and commissions issued the "Guiding Opinions on Promoting the Treatment of Black and Odorous Water Bodies in Rural Areas" (Huanban Soil [2019] No. 48), requiring that black and odorous water bodies in rural areas should be basicall...

AI Technical Summary

Problems solved by technology

[0007] In the existing technical field of micro-nano bubble generation, ultrasonic cavitation method and electrolysis method produce micro-bubbles with low efficiency and high energy consumption, which is not conducive to popularization and use in actual production; chemical reaction method has high cost and is easy to cause damage to water bodies. Secondary pollution is not conducive to direct use in natural water bodies; and the use of high-power high-speed motors to achieve high-speed shear mixing requires high manufacturing requirements for equipment, difficult processing, low bubble generation efficiency, high cost and inconvenient operation
