Montmorillonite nano-purification technology and device for medical sewage in hospital inpatient department

Abstract

The invention discloses a montmorillonite nano-purification technology and a complete set of device for different medical units in a hospital inpatient department, specifically surrounding a montmorillonite nano-pretreatment technology and the subsequent montmorillonite nano-purification integrated technology and device for medical sewage in multiple conventional wards, operating rooms, dressingchange rooms, nurse stations, hemodialysis centers, peritoneal dialysis centers, infectious wards or inpatient buildings, X-ray rooms, radiation intervention and cardiac catheterization angiography rooms and other medical units of the hospital inpatient department, so as to remove suspended solids, heavy metals, harmful ions, harmful organic substances, multiple pathogenic bacteria, parasites, residual antibiotics and other drugs, residual oil stains, surfactants, radioactive substances and the like in the medical sewage of the hospital inpatient department to the greatest extent, so as to reach the national medical sewage discharge standard, ensure the discharge safety of multiple medical sewage of the hospital inpatient department, and ensure the ecological and environmental safety around the hospital. The technology and the device have the advantages of good purification effect, low cost and long service life, and is expected to be applied to multiple medical sewage treatment in inpatient departments of multiple hospitals.

Description

technical field [0001] The invention belongs to the technical field of deep purification of medical sewage, and in particular relates to a montmorillonite nano-purification device for medical sewage in an inpatient department of a hospital, and also relates to a purification process using the purification device. Background technique [0002] Hospital sewage treatment is a major event closely related to people's life and health. Generally speaking, hospital sewage refers to the sewage discharged from hospitals (general hospitals, professional hospitals and other types of medical institutions) to the natural environment or urban pipelines. Its water quality varies with the nature, size and area of ​​different hospitals. Among them, the inpatient department of the hospital (including various conventional wards, operating rooms, dressing room, nurse station, hemodialysis center, peritoneal dialysis center, infectious disease room or inpatient building, X-ray room, radiological ...

AI Technical Summary

Problems solved by technology

[0005] The existing traditional sewage treatment technology does not fully consider the differences in the sewage discharge of various medical departments in hospitals, and some sewage purification processes still face problems such as incomplete sterilization and residual pollutants, and some medical sewage may still be affected by suspended solids, radioactive substances, residual Chlorine, small or trace amounts of bromate, nitrate, chlorite, chlorate and other inorganic salts and antimony, barium, beryllium, boron, molybdenum, nickel, thallium, arsenic, cadmium, lead, total chromium, hexa Valuable heavy metal ion pollution; residual antibiotics, sterilants, surfactants; residual formaldehyde, dichlorobromomethane, epichlorohydrin, vinyl chloride, 1,4-dichlorobenzene, microcystin-LR, herbicide Pine, glyphosate, carbon tetrachloride, volatile phenol and other organic pollutants

If these treatments are still incomplete, and the medical sewage that does not meet the standards is discharged externally, it will easily cause public health incidents, and the social impact will be very bad.

On the other hand, some traditional medical sewage purification technologies also have safety hazards. The possible safety hazards of chlorine dioxide treatment of medical wastewater were analyzed, and it was proposed that the town hospital should establish a complete safety guarantee system, strengthen operation training guidance, and implement normal To ensure the safety of chlorine dioxide generator application, we propose a montmorillonite nano-purification technology and device for hospital inpatient department medical sewage
