AI Technical Summary
The lack of a unified standard in the current technology to evaluate the bio-erosion defense performance of concrete sewage pipes, uneven nutrient solution delivery, interruption of supply or liquid retention problems affect the full contact between bacteria and nutrient solution, reducing the realism of bio-erosion simulation.
A pressure pump is used to pressurize the nutrient solution in the drip tube, ensuring a stable and continuous drip. A supporting structure rotates the concrete pipe to ensure uniform distribution of the nutrient solution. Combined with a spraying structure, this achieves uniform coverage and collection of the bacterial solution, improving contact efficiency.
It achieves efficient contact between nutrient solution and bacteria, enhancing the realism and consistency of the simulation, and is suitable for research on biological erosion mechanisms and experimental simulation.
