Embodiment 1
[0025] The cyanobacteria used in this example came from the shore of Dapu, Yixing, Taihu Lake, and the sampling time was at a more serious stage after the cyanobacteria outbreak period. The cyanobacteria mud was yellow-green and had a strong odor.
[0026] The cyanobacteria mud strengthening coagulation aid is based on 100 parts by weight, and the coagulation aid contains the following substances:
[0027] Polyaluminum Chloride: 10
[0028] Diatomaceous earth: 90
[0029] Take 2000ml of cyanobacteria mud, add hydrochloric acid to adjust pH=5, add 100g of cyanobacteria agent suspension of the present invention that is 20% by weight. Stir rapidly in a beaker for 3 minutes (stirring speed 200 rpm), and keep still to separate layers. The sludge settlement ratio (volume of sludge / total volume) at 15 minutes was 90%, and the sludge settlement ratio at 60 minutes was 70%. Quantitatively measure the sedimentation and stratification water of cyanobacteria sludge for advanced treatme...
Embodiment 2
[0033] The cyanobacteria used in this example came from the shore of Dapu, Yixing, Taihu Lake, and the sampling time was at a more serious stage after the cyanobacteria outbreak period. The cyanobacteria mud was yellow-green and had a strong odor.
[0034] The cyanobacteria mud strengthening coagulation aid is based on 100 parts by weight, and the coagulation aid contains the following substances:
[0035] Aluminum trichloride: 50
[0036] Diatomaceous earth: 50
[0037] Take 2000ml of blue-green algae mud, add hydrochloric acid to adjust pH=3, add 30% by weight of blue-green algae agent suspension of the present invention 100g. Stir rapidly in a beaker for 3 minutes (stirring speed 200 rpm), and keep still to separate layers. The sludge settlement ratio (volume of sludge / total volume) at 15 minutes was 80%, and the sludge settlement ratio at 60 minutes was 60%. Quantitatively measure the sedimentation and stratification water of cyanobacteria sludge for advanced treatment ...
Embodiment 3
[0041] The cyanobacteria used came from the shore of Dapu, Yixing, Taihu Lake. The sampling time was in the more serious stage after the blooming period of cyanobacteria. The cyanobacteria mud was yellow-green and had a strong odor. The experimental site is the pilot test base of Yixing Environmental Technology R&D Center of Nanjing University, Yixing Environmental Science Park Innovation and Entrepreneurship Park.
[0042] The cyanobacteria mud strengthening coagulation aid is based on 100 parts by weight, and the coagulation aid contains the following substances:
[0043] Ferrous sulfate: 30
[0044] Diatomaceous earth: 60
[0045] Bentonite: 10
[0046] Take 2000ml of cyanobacteria mud, add hydrochloric acid to adjust pH=4, and add 100g of cyanobacteria agent suspension of the present invention with a percentage by weight of 10%. Stir rapidly in a beaker for 3 minutes (stirring speed 200 rpm), and keep still to separate layers. The sludge settlement ratio (volume of slu...
