Embodiment 1
[0049] Comply with the above technical solutions, such as Figure 1 to Figure 4 As shown, this embodiment provides a comprehensive restoration device for polluted surface water, including a fixed frame 1, a control box 2 is installed in the middle of the fixed frame 1, and a buoy group 3 is symmetrically installed in the fixed frame 1 around the control box 2 A solar cell panel 4 is installed on the fixed frame 1 at the top of each buoy group 3, and a biological box 5 is installed on the fixed frame 1 at the bottom of each buoy group 3, and a plurality of side wall small holes 6 are uniformly processed on the biological box 5 ;
[0050] A photovoltaic controller 7 is installed in the control box 2, and the photovoltaic controller 7 connects the solar panel 4 and the storage battery 8, and the storage battery 8 supplies power for the aeration mechanism 9.
[0051] The size of the solar panel 4 is 1200×1000×50 mm, and the installation angle is 34.30 degrees.
[0052] The photo...
Embodiment 2
[0067] This embodiment provides a method for comprehensive restoration of polluted surface water based on immobilized cell technology. The method uses the comprehensive restoration device for polluted surface water as claimed in claim 1 to restore polluted surface water. The method specifically includes the following steps:
[0068] Step 1, preparation of substrate solution:
[0069] Configuration substrate solution, COD (chemical oxygen demand) in the substrate solution is 500mg / L, ammonia nitrogen concentration is 20mg / L, and phosphate concentration is 10mg / L; The deployment of COD in the substrate solution is to deploy by conventional organic matter Yes, as long as the COD in the matrix solution meets the required concentration.
[0070] Step 2, preparation of bacterial suspension:
[0071] Take the sludge mixture from the local sewage plant to treat the polluted surface water. In this example, the suspended solids concentration of the mixture is 3000 mg / L, and the sludge ...
Embodiment 3
[0079] This example provides a method for comprehensive restoration of polluted surface water based on immobilized cell technology. The process steps of this method are the same as those in Example 1, the only difference being that artificial aquatic plants are not suspended at the bottom of the bio-box.
[0080] After 1 month of restoration, the water quality at 6m below the bio-box was tested, and the dissolved oxygen concentration was 4.1mg / L, the total nitrogen concentration was 1.3mg / L, the COD was 28mg / L, and the total phosphorus concentration was 0.07mg / L. Compared with the original water quality, it has been greatly improved, but the improvement effect is not as good as that of Example 2, indicating that the artificial aquatic plants have also promoted the water quality restoration effect.
