Sewage treatment device and method for landscape river way

Abstract

The invention discloses a sewage treatment device for a landscape river way. The sewage treatment device comprises a sludge separation tank, an oxygenation tank and a disinfection tank, wherein a mixing cavity, a settling cavity and a sludge collecting cavity are sequentially arranged in the sludge separation tank from top to bottom, an oxygenation pipe and a rotating device are arranged in the oxygenation tank, and a flow dividing device and a heating plate are arranged in the disinfection tank. A sewage treatment method comprises the following steps: (1) filtering suspended matters; (2) separating sludge; (3) carrying out oxygenation treatment on sewage; (4) disinfecting the sewage; (5) inspecting the water quality; and (6) carrying out cleaning, inspection and repair. The sewage treatment device is simple in structure and strong in practicability; the sewage is gradually treated by virtue of the sludge separation tank, the oxygenation tank and the disinfection tank, so that the sewage treatment quality is effectively improved; meanwhile, by utilizing an oxygenation generator and an oxygenation pipe, the dissolved oxygen content in the sewage is increased, and the self-cleaning capacity of the river way is improved; and the device is high in working efficiency and low in energy consumption, the sewage treatment effect is obvious, and the comprehensive utilization rate is effectively increased.

Description

technical field [0001] The invention relates to a landscape river sewage treatment device and a 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 quality deterioration, and r...
