Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a magnetic flocculation separation device and method for sewage treatment. Background Art

[0002] Sedimentation is a common treatment method for sewage treatment, but the natural sedimentation efficiency is low. For this reason, magnetic coagulation treatment technology has emerged. Magnetic coagulation technology is based on traditional coagulation technology and simultaneously adds magnetic powder to it, so that it is combined with coagulants, pollutants, etc. to form a magnetic complex. Then, the method uses its own high specific gravity and fast sedimentation characteristics or uses magnetic separation equipment to accelerate solid-liquid separation, thereby removing pollutants.

[0003] Magnetic enhanced coagulation technology is widely used in the field of sewage treatment. By adding magnetic seeds into the sewage and coagulants, flocculants and other chemical agents, a high-density, compact magnetic floccules with magnetic seeds as the core are formed. Compared with ordinary floccules, the magnetic floccules have a faster sedimentation rate. In order to facilitate the recycling of magnetic seeds, the magnetic floccules are usually passed into a magnetic drum device after high-speed shearing, and the magnetic seeds are separated and collected by the magnetic drum device for subsequent use. The existing magnetic drum equipment is mainly composed of a fixed magnetic cylinder and a non-magnetic cylinder rotating outside the magnetic cylinder. The sewage containing magnetic powder and sludge enters the separation device from one end of the drum. The fixed magnetic poles suck out the magnetic particles and attach them to the surface of the drum. As the drum rotates, they are brought to the low magnetic area at the edge of the magnetic cylinder and unloaded from the magnetic material outlet. The non-magnetic material flows along the separation trough to the non-magnetic material outlet under the action of gravity. For example, the Chinese patent No. CN201620896814.2 provides a magnetic In the magnetic powder recovery device of flocculation sedimentation technology, such as the above-mentioned existing magnetic powder recovery equipment, firstly, in order to effectively collect the magnetic powder, a high-speed shearing machine is required to be separately equipped to break up the magnetic floccules; secondly, the contact area between the sewage containing magnetic powder and floccules and the magnetic cylinder is small. When the sewage flows through the magnetic cylinder, it will settle due to its own gravity, resulting in incomplete adsorption of the magnetic cylinder; thirdly, during the adsorption process, the magnetic cylinder will adhere part of the floccules to the surface of the magnetic cylinder through magnetic powder adsorption, resulting in more floccules being mixed in the magnetic powder after collection.
