Modern wastewater treatment methods are largely classified into physical treatment, chemical treatment and biological treatment. The physical treatment method is a waste water treatment method for separating and recovering undecomposed suspended pollutants (including oil films and oil droplets) from waste water by physical action, and may be classified into a gravity separation method, a centrifugal separation method, a sieve filtration and retention method, and the like. The processing units belonging to the gravity separation method comprise precipitation, floating (air flotation) and the like, but the processing effect is poor, and the processing time is long; the chemical treatment method is a wastewater treatment method for separating, removing or converting pollutants in a dissolved or colloidal state in wastewater into harmless substances through chemical reaction and mass transfer. In the chemical treatment method, a treatment unit based on chemical reaction generated by adding a medicament has the defect of generating secondary pollution to the environment; the biological treatment method is a wastewater treatment method for converting organic pollutants in a solution, colloid and fine suspension state in wastewater into stable and harmless substances through the metabolism of microorganisms, but the biological treatment method has certain limitations on the requirements of environment and the quality of wastewater except for long time use.
