Description
Technical Field
The utility model relates to the technical field of water treatment equipment, in particular to a secondary tributary efficient oxygenation circulation device.
Background
The urban black and odorous water body not only brings extremely bad sensory experience to the masses, but also is a prominent water environment problem which directly influences the production and life of the masses. The water pollution control action plan proposes a control target that the black and odorous water body in the urban built-up area is totally eliminated in 2020 and 2030, and the black and odorous water body in the urban built-up area is controlled to be within 10 percent. The urban black and odorous water body remediation has become an important content for improving urban environment work, and the remediation task is very difficult, and especially the problem of secondary and lower tributary black and odorous in each large river basin is more prominent.
The cause of black and odorous water bodies is numerous, and the following 2 aspects can be briefly summarized: (1) anoxic to the water body. Under the state of oxidative decomposition, the oxygen consumption rate of organic matters in the water body is obviously higher than the reoxygenation rate, so that the anoxic phenomenon in the water body is more and more obvious, when a large amount of iron elements, manganese elements and other substances appear in the water body, the reduction phenomenon can appear under the condition of insufficient oxygen, so that the iron substances react with the manganese substances and sulfur substances in the water to form ferrous sulfide, manganese sulfide and other substances, and the phenomena of blackening, odorization and the like of the water body are obvious. (2) insufficient hydrodynamic conditions. The water flow is not smooth, the water sample of the water body is directly influenced, the water body is polluted to different degrees, and when the water quality of the water body is deteriorated, the water body is subjected to black and odorous problems.
In order to remedy black and odorous water bodies, the prior art mainly increases the oxygen content in water and improves hydrodynamic force. The existing water oxygenation modes mainly comprise chemical oxygenation, mechanical oxygenation, biological oxygenation and the like. For example, the application number is 201510223654.5, the patent name is Chinese utility model of a biological composite oxygenation agent and a preparation method thereof, wherein the chemical oxygenation agent and the biological bacteria agent can reach the bottom of a pond at the same time, so that dissolved oxygen at the bottom of the pond is increased, microecological balance at the bottom of the pond is improved, but the chemical oxygenation is easy to destroy the ecology of a water body; the photosynthesis effect of biological oxygenation through aquatic plants and phytoplankton is slower; the mechanical oxygenation is applied more, and the mechanical oxygenation is mainly to increase the dissolved oxygen in the water body by means of effectively contacting the water body with air and continuously supplementing oxygen to the water body through a microporous pipeline matched with equipment such as a Roots blower or a screw blower. For example, the application number is 202222979077.0, and the patent name is China utility model of a black and odorous water body restoration oxygenation device, which increases dissolved oxygen in a water body by using a bottom aeration mode. The disadvantage of this approach is: the air source is mainly used, longer operation time is needed, energy consumption is larger, the bottom aeration is mainly used, and the whole circulation is poor. In the prior art, the hydrodynamic force of the closed water body is improved by means of special equipment, equipment investment is increased, for example, the application number is 202120070113.4, and the patent name is a structure for improving the hydrodynamic force of the closed water body, which increases the rotation rate of a water spray pipe and improves the hydrodynamic force.
