Embodiment 1
[0050] A system for repairing river and lake water bodies by a floating water purification field, said system successively includes: grille, water pump, pre-magnetization device, water inlet pipe, SS sedimentation tank, magnetizer, drain pipe, water distribution pipe, floating purification field;
[0051] in:
[0052] The grid is used to filter large particles of garbage, plant residues, and large phytoplankton in the water body of rivers and lakes; the grid gap of the grid is 5mm-50mm, the installation angle is 60°-70°, and the maximum flow rate ≥160m 3 / h, the maximum liquid velocity ≥ 0.3m / s.
[0053] The water pump is used to make water pass through the grid, and extract the water passing through the grid to the ss sedimentation tank;
[0054] The pre-magnetization device is arranged in the water inlet pipe of the ss sedimentation tank, and is used to pre-magnetize the water entering the ss sedimentation tank; the pre-magnetization device is a multi-stage permanent magne...
Embodiment 2
[0067] The system and method for repairing river and lake water bodies using the floating water purification field described in Example 1, the floating purification field is formed by collocation of canna, reed, calamus and iris, and different magnetic field strengths are given at different growth stages. The induction effect of magnetized water on plant biohormones in different growth stages of plants.
[0068] Table 1 Seed germination period
[0069]
[0070] During seed germination, cytokinin (CK), gibberellin (GA), abscisic acid (ABA), and auxin (IAA) have a high positive correlation with seed germination and control seed germination. Therefore, during the seed germination period, by studying the effects of different magnetic field strengths on biological hormones such as cytokinin, the optimal magnetic field strength for seed germination was explored.
[0071] Through experiments, it is found that when the magnetic field strength ranges from 50 to 100mT, it can effect...
Embodiment 3
[0081] Using the system and method for repairing river and lake water bodies described in Example 1, by studying the influence of different magnetic field strengths on the microbial community structure, the recovery of functional flora induced by different magnetic field strengths was explored.
[0082] Table 4 Microbial detection indicators
[0083]
[0084] The experimental results show that the magnetized water magnetized by different magnetic field strengths has obvious induction effect on nitrifying bacteria and ammonifying bacteria, and the maximum abundance of nitrifying bacteria is between 500mT and 800mT; while the maximum abundance of ammonifying bacteria appears between 300mT and 500mT .
