Embodiment 1

[0050] Such as figure 1 Shown, the present invention proposes a kind of method that constructs ecological riverbed with artificial biofilm, and its steps are:

[0051] 1. Preparation of artificial biofilm products for river course restoration (patent-an artificial biofilm and its preparation method ZL200610124636.2): ​​select efficient application strains, including Bacillus, photosynthetic bacteria and other probiotics, which can efficiently degrade organic matter, remove The performance of phosphorus denitrification and deodorization, as well as the strains covering freshwater-brackish water-seawater, can be used in sea channels affected by tides; its artificial biofilm products have the ability to resist drought, radiation and freezing environments. It also has metabolic activity in the water temperature range of 10-40 ℃, and has decontamination effect.

[0052] 2. Implement artificial biofilms on ecological riverbeds: Many rivers not only have strong fluidity, but also ha...

Embodiment approach

[0056] Lay the selected artificial biofilm on the river bed, and according to the bottom quality of the river bed, select the appropriate connecting buckle to fix the film on the river bed, and add pebbles on it to enhance the impact resistance and keep it at the bottom of the river. The moved position becomes a riverbed with biodegradable function, which strengthens its removal efficiency of pollutants, reduces the accumulation of river sediments, and also has the function of bottom dredging.

[0057] (2) For the deep water area of ​​the river (higher than 50cm-500cm, any data within this range is acceptable):

[0058] The method of hanging artificial biofilms in series: use stainless steel wire rope or other durable ropes to string one end of the artificial biofilms, and use plastic tubes or rings with holes to keep the distance between the films. Eventually form a line. After the diaphragms are connected in series, they can be fixed below the water surface by using trestle...

Abstract

The invention discloses a method for constructing an ecological riverbed by using an artificial biological membrane. The method comprises the following steps: A, preparing an artificial biological membrane product for river restoration; B, implementation the artificial biological membrane on an ecological riverbed: for the riverway water shallow area, laying the selected artificial biological membrane on the riverbed by adopting a membrane type artificial biological membrane, and fixing the membrane on the riverbed through a connecting buckle; for a river channel deepwater area, connecting theartificial biofilms in series and hanging the biofilms, and submerging the artificial biofilms under the water surface after being connected in series, and putting a granular artificial biological membrane at the bottom of the riverway. The invention mainly aims to solve the problems of high flowability of river water, large water level change of some rivers, tidal influence and the like in pollution prevention and treatment. An artificial biological membrane is adopted as a core technology for constructing an ecological riverbed, so that the purposes of improving the riverway purification efficiency and reducing sediments are achieved, the problems of large riverway water body flowability, tidal influence and water level change are solved, the water body purification capacity is improved, and the ecological restoration target is achieved.

Description

technical field [0001] The invention belongs to the technical field of in-situ ecological restoration of river channels, and more specifically relates to a method for constructing an ecological river bed with artificial biofilm, which is especially suitable for in-situ ecological restoration of flowing water bodies, water environments with large water level fluctuations and water environments affected by tides. Background technique [0002] With the rapid development of social economy, the negative impact of human production and living activities on the environment has become increasingly prominent. As early as the 1930s to 1950s in foreign countries, river water environmental pollution control and river water quality protection began. From the 1950s to the 1980s, the ecological restoration theory was formed based on the "near-natural river management engineering" as the main theoretical basis. The 80s After the 1990s, the focus of river ecological restoration expanded to ri...
