The black and odorous water body treatment device can work only by connecting one water pump, and has simple equipment and lower cost; the water input by the water pump is the water of the water body to be treated, no additional tap water and the like are needed, and the use cost is low; in addition, the application has high efficiency of water treatment, the existing micro-bubble generating device can increase the oxygen content of water body to one cube per hour, and the application can reach 10-20 cubes per hour; when the same amount of sewage is treated, the existing equipment not only occupies larger equipment volume, but also occupies larger container or tank for storing sewage; as the water inlet end of the treatment device is far away from the micro-bubble water output end, a self-circulation movable water body is formed in the water body.
Therefore, the treatment device for the black and odorous water body has the remarkable advantages that: 1. as the regulating equipment of the dissolved oxygen of the water body, oxygen-enriched water is supplied to the water body, especially the anoxic layer at the bottom, in the form of micro bubbles and oxygen-enriched water; 2. when the sewage and air of the medium are mixed and pass through the nozzle at high pressure and high speed, tiny suspended matters in the sewage are adsorbed and flocculated by micro bubbles to be separated (possibly become floating foam); 3. when the sewage of the medium passes through the nozzle at high pressure and high speed, part of water biological cells such as blue algae in the sewage are broken by high-pressure water pressure and impact, and part of organic matters are decomposed under electrochemical and physical effects such as ionization, crushing and the like generated by high-pressure high-speed mixing of gas and liquid.
According to the application, after air (oxygen) is highly mixed and fused into water through the micro-nano ejector, oxygen-enriched water is introduced into the bottom of the water body through a plurality of water pipes 18 in the figure to promote improvement of anoxic or anaerobic environment at the bottom, and common aeration equipment only pumps air into the water body, while the application is highly gas-soluble (about 40% of dissolved gas), so that water (not counting bubbles around water) from the water pipe 18 is already oxygen-enriched water.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same; while the invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that the present invention may be modified and equivalents substituted for elements thereof; without departing from the spirit of the invention, it is intended to cover the scope of the invention as claimed.
