Embodiment Construction
[0042] Such as Figure 2 to Figure 4 As shown, it is a kind of stepped aerobic urban river treatment equipment of the present invention. The river treatment equipment includes a treatment tower 1, a solar device 2, a water pump 3 and artificial aquatic plants 4. The treatment tower 1 is located on the river bank 9, on the right side of the treatment tower 1 The end surface is stepped. Through the stepped design, the dissolved oxygen content in the water is further increased, and the purified water quality is further purified. When the water flow hits the steps, strong turbulence occurs, and the turbulent kinetic energy increases, resulting in a large number of air bubbles. Involvement increases the oxygen transmission area of the water body, thereby increasing the dissolved oxygen content of the water body. A steel plate 5 is arranged on the top surface of the treatment tower 1. The size of the steel plate 5 matches the size of the top surface of the treatment tower 1. The st...

The invention discloses a step oxygenation urban river treatment equipment and a sewage treatment method thereof. The river treatment equipment includes a treatment tower, a solar device, a water pump and artificial aquatic plants. A dropboard is provided indoors, and cobblestones are arranged inside the dropboard. The solar energy device includes a solar panel, a connecting column, a solar controller and an installation plate. The artificial aquatic plants are connected with fixed brickwork. The sewage treatment method includes the following steps: ( 1) Construction of treatment tower; (2) Installation of drop board; (3) Installation of solar energy device; (4) Installation of water pump and storage battery; (5) Installation and placement of artificial aquatic plants; (6) River sewage treatment. This sewage treatment method not only increases the dissolved oxygen content in the water, makes the purified water better, but also facilitates construction and reduces the difficulty of construction. Moreover, through the auxiliary effect of artificial aquatic plants, the self-purification ability of the river channel is improved, and later maintenance is also relatively easy. convenient.
Description
technical field [0001] The invention relates to a stepwise aerobic urban river treatment equipment and a sewage treatment method thereof. Background technique [0002] In the formation and development of cities, rivers, as important resources and environmental carriers, are related to urban survival, restrict urban development, and are important factors that affect urban style and beautify the urban environment. Urban rivers have various ecological functions such as water supply, green space, environmental protection, transportation, and cultural education. It shows irreplaceable significance in the construction of cities and the expansion of urban space development. With the acceleration of urbanization in our country, land development and utilization on both sides of the river have damaged the function of urban rivers, and a large amount of industrial and domestic sewage has been directly discharged into the river without treatment, causing river water pollution, water qu...
