Magnetic separation techniques are generally well known and are a technique for separating substances by magnetic force, and the application of the technique has penetrated into various fields. The development has progressed from initial mineral separation, coal desulfurization to industrial water treatment, separation of magnetic and non-magnetic elements to separation between components of a homogeneous mixture of diamagnetic fluids. As a clean and energy-saving new technology, magnetic separation will show attractive development prospects.
The magnetic precipitation technology is that magnetic powder is synchronously added in the common coagulation precipitation process to be combined with pollutants into a whole by flocculation, so that the coagulation and flocculation effects are enhanced, and the generated floc is higher in density and firmer, thereby achieving the purpose of high-speed precipitation. The magnetic powder can be recycled through the magnetic drum. The residence time of the whole process is very short, so the probability of the anti-dissolution process of most pollutants including TP is very small, and in addition, the magnetic powder and the flocculating agent added in the system have good adsorption effect on bacteria, viruses, oil and various micro particles, so the removal effect on the pollutants is better than that of the traditional process.
The existing sewage purification equipment needs to pump out water in a water tank for purification and then put the water in the water tank after purification, and has the problems of complex operation steps, high operation cost and the like.
