Multifunctional aquatic plant sewage treatment device

Abstract

The invention discloses a multifunctional aquatic plant sewage treatment device, belonging to the field of sewage treatment. The multifunctional aquatic plant sewage treatment device comprises a floating frame, wherein two ends of the floating frame are movably mounted on a river levee through limiting rails, a floating body is fixed on the lower side of the floating frame, the floating frame is provided with a plurality of net cages, the net cages are uniformly provided with mesh holes in a penetrating manner, and water surface cleaning mechanisms are mounted on the left side of the front portion of the floating frame and on the right side of the rear portion of the floating frame. According to the invention, the device can prevent aquatic plants from being scoured due to riverway water rising, water falling and a high water flow speed, ensures sewage treatment effect, avoids economic loss, cleans and discharges impurities such as algae and garbage floating on a water surface, prevents the impurities from influencing the sewage treatment effect of the aquatic plants, beautifies the river surface, facilitates taking-out of the aquatic plants from the net cages, clears away impurities in the net cages and guarantees smooth entering of the sewage into the net cages, so the sewage treatment effect of aquatic plants is guaranteed; and in addition, the aquatic plants can be conveniently replaced when the aquatic plants are dead.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a multifunctional aquatic plant sewage treatment device. Background technique [0002] In river sewage treatment, the water body is often treated by planting aquatic plants. After retrieval, Chinese Patent No. CN 210193610 U discloses a sewage treatment device for aquatic plants, which includes a sewage treatment area, a sewage inlet, a sewage outlet, and a first barrier. The plate mechanism, the second barrier plate mechanism, the first group of aquatic plants and the second group of aquatic plants, the sewage flows in from the sewage inlet and is discharged from the sewage outlet, and the first barrier plate mechanism and the second barrier plate mechanism are located in the sewage treatment area In the sewage treatment area, an auxiliary frame is also provided, the auxiliary frame is located at the center of the first blocking plate mechanism and the second blocking p...

Problems solved by technology

[0003] The prior art still has the following disadvantages when using aquatic plants to treat sewage: when the existing aquatic plant sewage treatment device is used to purify sewage in the river, the position of the floating aquatic plants is not easy to control, especially when the river is flooded or falling into the water. Or when the flow speed increases, the aquatic plants are easily washed away, unable to exert their professional sewage treatment effect, and at the same time cause economic losses; in addition, aquatic plants are affected by algae and garbage floating on the water surface, reducing the sewage treatment effect. At the same time, it affects the appearance, so the present invention proposes a multifunctional aquatic plant sewage treatment device
