Description

Technical Field

[0001] The invention belongs to the technical field of magnetic coagulation, and in particular relates to an environmentally friendly magnetic coagulation sedimentation treatment system. Background Art

[0002] Magnetic coagulation technology is a combination of coagulation technology and magnetic separation technology. It is an innovative improvement on the traditional coagulation, sedimentation and filtration processes. It uses recyclable modified magnetic seeds to enhance the flocculation reaction and achieve a high-efficiency sewage treatment process with high-speed sedimentation. Its principle is to add appropriate amounts of coagulants, magnetic seeds, coagulants, etc. to the raw water to quickly flocculate the pollutants. At the same time, the magnetic seeds greatly improve the quality of the flocs, accelerate the floc sedimentation rate, increase the surface load of the sedimentation tank, shorten the hydraulic retention time, and improve the treatment efficiency and effluent water quality standards. Its effluent effect is good, and it has a good removal effect on SS, TP, COD, BOD, etc.

[0003] At present, the magnetic coagulation sedimentation treatment system will separate and treat the magnetic seed sludge discharged from the clarification tank, and discharge the treated sludge. However, the whole system does not have a structure or function to detect the content of the treated sludge. Therefore, the magnetic seed separation is not thorough, which affects the subsequent treatment of the sludge. If the sludge is discharged directly, it may also cause environmental problems. At the same time, in the existing system, the clarification tank mainly relies on the gravity of the magnetic seed sludge to achieve sedimentation, which is time-consuming. Therefore, it has great limitations in practical application and has room for improvement. Summary of the invention
