Grid, anaerobic and RABF integrated medical wastewater purification method

Abstract

The invention discloses a grid, anaerobic and RABF integrated medical wastewater purification method, and relates to the technical field of medical wastewater treatment. The method comprises the following steps of: S1, removing large substances; S2, carrying out gas-liquid-solid three-phase separation; S3, increasing the content of dissolved oxygen; and S4, disinfecting and discharging. The equipment adopted is small in occupied area, and complex and tedious operation is not needed. Through a simple process and structure, efficient treatment of medical wastewater can be realized, and the wastewater treatment effect can be ensured. Gas-liquid-solid three-phase separation can be realized. The sludge loss of a medical wastewater biochemical treatment system is solved, the sludge interception efficiency for passing water is high, and the problem that the existing sewage purification system is poor in treatment effect and like is solved. Integrated circulation sludge self-circulation is realized, the reflux ratio is effectively increased, the denitrification effect is enhanced, and the content of dissolved oxygen in water is increased. Meanwhile, a disinfection structure is arranged, so that the purified sewage can be effectively sterilized and disinfected, and discharge of up-to-standard sewage is realized.

Description

technical field [0001] The invention relates to the technical field of medical wastewater treatment, in particular to an integrated grid, anaerobic and RABF medical wastewater purification method. Background technique [0002] Medical wastewater has attracted public attention many times. The discharge of medical wastewater has caused great harm to water resources and has become a "source" that endangers public health. In some areas, only a handful of hospitals can truly meet the national discharge standards. Irregular laws and weak awareness of environmental protection have resulted in the direct discharge of medical wastewater and the current situation of "high pollution and low governance" in major hospitals. Medical sewage is mainly from the hospital's consultation rooms, laboratories, wards, laundry rooms, The sewage discharged from photographic studios and operating rooms has complex sources and components. Hospital sewage contains a large number of pathogenic bacteria...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a comprehensive grid, anaerobic, and RABF medical wastewater purification method, which solves the complex process structure in the prior art proposed in the above-mentioned background art, many processing equipment, and occupies an area of Large size, cumbersome operation, and the loss of sludge in the medical wastewater biochemical treatment system, which makes the interception of overwater sludge not ideal. At the same time, it does not have disinfection function, and the treatment effect of the sewage purification system is poor.
