Abstract

The invention relates to the technical field of sewage treatment, in particular to a medical sewage purification and disinfection device. The medical sewage purification and disinfection device provided by the invention comprises an anaerobic treatment mechanism, an aerobic treatment mechanism, a ceramic flat sheet membrane filtration mechanism, a disinfection mechanism and a backwashing mechanism. Compared with the prior art, the medical sewage purification and disinfection device has the advantages that the a sedimentation tank is replaced by membrane produced water, so that the occupied area is smaller; a biological filler and membrane process,double membranes are combined, the sludge concentration is high, so that the impact resistance of the system is improved, and the treatment efficiency is ensured; the feeding cost of a disinfectant is reduced through the filtering and separating effects of a ceramic flat sheet membrane, the sludge age of the system is long, the sludge concentration is high, the sludge yield is low, the service lifetime of an inorganic ceramic membrane is long, and secondary pollution caused by sludge, membrane materials and the like is small; based on theoxidation resistance of the inorganic ceramic membrane, effluent containing a disinfection oxidant of the disinfection tank is directly used for backwashing, so that membrane pollution can be effectively inhibited.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a medical sewage purification and disinfection device. Background technique [0002] In recent years, with the rapid development of my country's medical and health undertakings, the scale and number of hospitals have continued to expand, and the discharge of medical sewage has also been increasing. Compared with ordinary domestic sewage, in addition to CODcr, BOD5, SS contained in domestic sewage, medical sewage also contains a large number of bacteria, viruses, parasites, heavy metals and other toxic and harmful substances to the human body, and it has space pollution, acute infection and Latent infection and other characteristics, if the sewage is improperly treated, such as the unstable concentration of suspended solids in the effluent, the large amount of remaining sludge leading to secondary pollution, and the excessive dosage of disinfectants that destroy ecological saf...
