Problems solved by technology

On the one hand, this method increases the restoration cost and affects the landscape beauty of the water body. On the other hand, it isolates the plants from the bottom of the water body, which is not conducive to the restoration of plant growth and natural ecosystems.

Embodiment Construction

[0009] 1. The present invention divides the bed-type sewage ecological restoration technology system into two parts: the blocking-type floating plant planting net bed and the submerged plant planting net bed. Relying on the buoyancy of the float and the gravity of the floating plants and the netted floating bed, the blocking type floating plant planting net bed can maintain the required depth of the netted floating bed body when the water level rises or falls, and achieves the automatic adjustment of the netted floating bed with the water level function, so that the floating bed is always on the water surface; the frame is always on the water surface, so that the floating plants are fixed in the mesh floating bed area.

[0010] 2. Floating plants with high survival rate are planted on the intercepting floating plant planting net bed. The plants achieve a strong intercepting effect by blocking floating objects, settling suspended particles and reducing nutrient-rich substances. ...

Abstract

The present invention provides a novel bed sewage ecological restoration technology. According to the present invention, submerged plants are combined with the network bed technology to realize the full absorption of nutrients by the plants, and ultimately the purpose of recovering the natural ecosystem is achieved. The stain resistant, high temperature resistant and low temperature resistant submerged plants are selected to ultimately realize the riverway aquatic plant decontaminating function yearly. Net cages can be hung under the network beds to farm fishes, snails, shellfishes, and the like. During the restoration of the water, aquatic products can also be obtained. Compared with the conventional water environmental restoration methods, the novel bed sewage ecological restoration technology is more ecological, more environmental-friendly, more energy-efficient, and more economical, makes up for the defect of clearing contamination by changing water, overcomes the limitations of bottom in the restoration waters, and has broader application and simple maintenance.

Description

technical field [0001] The invention relates to the fields of ecological environmental protection and water body restoration, in particular to a novel bed-type sewage ecological restoration technology. Background technique [0002] my country has a large population and a shortage of water resources. With the development of industrial and agricultural production, the water quality of major water systems and lakes and reservoirs is deteriorating day by day. Sewage treatment plants in cities use activated sludge method, SBR, A / O, AB, A / A / O, oxidation ditch method and other processes to treat sewage through physical, chemical and biological effects. However, this kind of treatment system costs a lot of money, consumes a lot of fossil fuels, and is difficult to maintain. It cannot be implemented in areas with relatively backward economies. As a result, most of the sewage in our country is directly discharged into natural water bodies without any treatment. resources pose a serio...
