Abstract
There is provided a method for controlling bio-slimes in a clean circulating water system through a physical-chemical-superconducting high gradient magnetic separation coupling process. An inorganic composite flocculant is added to circulating water to gatherin the circulating water with micro-nano particles in hydrosol through demulsification to form alum floc. The resulting water passes through a superconducting high gradient magnetic separation system. A magnetic field strength of the superconducting high gradient magnetic separation system and flow rate of the circulating water are controlled to generate strong magnetic flocculation to allow floc to grow, such that thein the circulating water wraps the micro-nano particles to separate thefrom water.
