Embodiment Construction

[0039] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

[0040] Such as figure 1 with figure 2 Shown is an ecological sedimentation bed used for the treatment and in-situ restoration of deeply polluted river courses in a preferred embodiment of the present invention. The ecological sedimentation bed includes a frame body 2, which is divided into plant planting areas on both sides and a filling area in the middle. Both sides of the frame main body 1 are provided with semicircular handles 5, which are convenient for lifting and carrying the whole sunken bed, and then recycle zeolite, fillers and plants. In addition, there are hinges 7 on both sides of the frame main body 2, which are used for connection and fixing between adjacent main bodies to prevent the sedimentation bed from slipping in the sediment, such as image 3 shown. The frame main body 2 is made of PVC material and is formed by one-time blo...

Abstract

The invention discloses an ecological sinking bed for deep polluted river treatment and in-situ remediation and a method thereof, and belongs to the field of environmental protection devices. The ecological sinking bed comprises a frame body, and the frame body is divided into plant planting areas located on the two sides and a filling area located in the middle. The plant planting area is used for planting aquatic plants, and the filling area is sequentially filled with zeolite, a solidified microorganism filler and a three-dimensional elastic filler from bottom to top in a layered mode. Theecological sinking bed is characterized in that the water body is purified in multiple modes by combining the physical adsorption and microbial degradation effects of the filler and the zeolite surface and the purification function of plants such as reeds, and a knife edge is designed for cutting the reeds, so that the problems of unfavorable conditions of easy damage, short tolerance time and thelike of floating beds due to large rain water flow speed and sun exposure and difficult recovery caused by rooting of the reeds are solved. The ecological settling bed is nontoxic and harmless in material, is not easy to damage, is durable, is convenient to recycle and reuse after finishing, and does not generate secondary pollution.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to an ecological sedimentation bed used for the treatment and in-situ restoration of deeply polluted river courses. Background technique [0002] At present, the water bodies of most rivers, lakes and reservoirs in my country do not meet the five-category surface water standards, and the treatment of polluted water bodies has become an urgent need for social and economic development and ecological environment construction. For river restoration, the traditional river dredging, sediment covering, water diversion, and water replenishment repair methods have problems such as complex engineering, difficult operation, huge cost, and repeated effects. [0003] Ecological sedimentation is a commonly used in-situ restoration technology for the treatment of polluted rivers and lakes, and it has a remarkable effect in the process of controlling water pollution and restoring e...
