Problems solved by technology

[0004] The purpose of the present invention is to provide an ecological river floating bed system, which solves the problem that in the existing ecological floating bed, the root system of emergent plants floats on the surface, and the microbial film is only attached to the vicinity of the floating bed, and the purification effect is poor. In the low water level or dry season, it is impossible to keep enough water for the growth of floating bed plants, resulting in the death of floating bed plants and affecting the technical problems of water purification effect

Embodiment Construction

[0032] The present invention will be further described in detail below with reference to the accompanying drawings:

[0033] like Figure 1-5 Indicated. An ecological river floating bed system, including channel foundation, and purification devices;

[0034] The end surface of the channel base portion is equal, the upper opening is large, the lower end is tightened; the channel base portion is sequentially divided into the flow direction 101, the flushing section 102, the uniform flow section 103 and the silt section 104; A micro-retainer 105 is provided between the sections 101 and the brush section 102; the bottom surface of the flushing section 102 is depressed downwardly to form a water storage pit;

[0035] The purification apparatus includes plant floating bed 201 and a ferrite purification device 202, and the purge apparatus is connected to the channel base portion 100 through the first connection, and the purification device is located downstream of the micro-retraction dam...

Abstract

The invention discloses an ecological river floating bed system which comprises a channel foundation part and a purification device. The end face of the channel foundation part is in an isosceles trapezoid shape, the upper end opening is large, and the lower end is tightened. The channel foundation part is sequentially divided into a water stopping section, a washing section, a uniform flowing section and a silting section in the water flow direction. A micro water retaining dam is arranged between the water stopping section and the scouring section; the bottom surface of the washing section is sunken downwards to form a water storage pit; the purification device comprises a plant floating bed and an iron-carbon purification device, the purification device is connected with the channel foundation part through a first connecting rope, and the purification device is located at the downstream of the micro retaining dam; the plant floating bed is connected with the iron-carbon purification device through a second connecting rope, and the balance iron-carbon purification device is located below the plant floating bed; and floaters are arranged on the plant floating bed. And water purification plants are planted in water purification plant planting baskets of the plant floating bed. The nitrogen and phosphorus polluted water body is gradually digested under the action of plants, microorganisms and iron-carbon micro-electrolysis, and the purification effect is very good.

Description

Technical field [0001] The present invention relates to the field of floating bed, and in particular, to an ecological river floating bed system. Background technique [0002] Ecological floating bed, also known as artificial floating bed, ecological buffles, etc., is currently common measures for COD, nitrogen and phosphorus content in the river or lake, floating bed relies on its own buoyancy to float the river or lake surface, through it planted Aquatic plants and fillers achieve removal and purification of nutrient salts. [0003] At present, due to biological purification, the root of the plants is floating on the surface, the microbial film is only attached to the floating bed, and the purification effect is poor. When the contaminant content is high, it is difficult to obtain satisfactory purification. Effect. And the existing ecological floating bed is low in the water level or the dry water is not possible for the growth of the floating bed plant, causing the floating be...
