The wastewater in the hospital contains a variety of pathogenic bacteria, direct discharge will cause groundwater or river pollution, so it should be reasonably treated and purified to meet the national sewage discharge standards before discharge. Hospital sewage treatment can use chlorine dioxide disinfection powder (special for hospital sewage treatment), the content of 10% and 48% two kinds. With the sewage treatment equipment, the AB agent of the powder is dissolved separately and poured into the sewage to be treated. It can kill E. coli, Salmonella and Shigella.
Another kind of active oxygen disinfection powder, also called potassium persulfate compound salt, is specially used to treat hospital sewage. The disinfectant powder with potassium persulfate compound salt, citric acid and sodium chloride as main raw materials, the content of potassium persulfate is 18%-25%, the content of sodium chloride is 5%-6%, and the content of active oxygen is 13%±1.3%. It can kill staphylococcus aureus, Escherichia coli, pathogenic yeast and other common bacteria and bacterial spores in hospital infections.
The sputum of infectious patients (e.g. tuberculosis patients) and sputum specimens after examination by the Laboratory Department, polluted wastes, as well as drainage fluids of patients in various departments, chest and abdominal fluids, etc., are classified and collected by the generating departments, and are contained in leak-proof special buckets, sent to the sputum room, and after boiling at high temperatures for 30 minutes or mixing with 2000 mg/L chlorine-containing disinfectant for 30 minutes, the wastewater is discharged into the hospital sewage treatment system.
Wastewater: medical life wastewater from the sewage system into the hospital sewage treatment station. In the treatment station in accordance with national requirements, the use of equipment and agents certified in accordance with national regulations for sedimentation and dehazardous treatment and then discharged. Generally, chlorine dioxide is used to treat the wastewater for discharge. Manufacturers of hospital wastewater treatment equipment and chemical reagents are required to be certified and must be purchased with qualifications. There should be tested after sewage treatment, it is best to ask a qualified third-party testing company testing.
