1. Wastewater is treated as follows: High-risk wastes such as culture media of pathogenic organisms and viral seed preservation solutions in the laboratory department should be sterilized in the laboratory with pressure steam before being treated as other infectious wastes. Sputum from infectious patients (e.g., tuberculosis patients), sputum specimens after examination, contaminated wastes, drainage fluids from patients, and thoracic and ascitic fluids are collected from the departments. They are sent to the sputum room with special leak-proof special buckets. The wastewater is discharged into the hospital sewage treatment system after boiling at high temperature for 30min or adding 2000mg/L chlorine disinfectant for 30min.
2. Radiological waste:It is generated and discharged through special piping into separated cesspools, which are degraded and discharged into the hospital sewage treatment system. Chemical waste:Radiology developers are discharged into the hospital sewage treatment system after generations. Fixed solutions are put in special leak-proof buckets and given to recycling companies for disposal. Chemical reagents and waste solutions from the Laboratory and Pathology Departments are discharged into the hospital sewage system for treatment. Wastewater:Medical and domestic wastewater is discharged into the hospital sewage treatment station through the sewage discharge system. Using equipment and agents that comply with national regulations and certified according to national requirements, the wastewater is discharged after sedimentation and abatement at the treatment station. Generally, wastewater is treated and discharged with chlorine dioxide.
1. The hazards of air pollution mainly include the following: Hazards to human health:People need to breathe air to sustain life. An adult breathes about 20,000 times a day and inhales up to 15 ~ 20 m3 of air. therefore, polluted air directly affects human health. Air pollutants are harmful to the human body in many ways, mainly in the form of respiratory diseases and physiological dysfunctions, as well as diseases caused by irritation of mucous membrane tissues such as the eyes and nose. When the concentration of pollutants in the air is very high, it can cause acute pollution poisoning within a few days, worsening the condition and even causing death. In fact, even if the concentration of pollutants in the air is not high, the human body for many years to breathe this polluted air can also cause chronic bronchitis, bronchial asthma, emphysema, lung cancer and other diseases.
2. Harm to plants:Air pollutants are very harmful to plants, especially sulfur dioxide and fluoride. When the concentration of pollutants is very high, it will cause serious harm to plants, causing damage spots on the surface of plant leaves, or directly make the leaves wither and fall off; the concentration of pollutants is not high, it will cause chronic harm to the plant, so that the plant leaves fade to green, or on the surface of the green look no symptoms of harm, but the plant's physiology has been affected by the impact of the plant's yield and deterioration of the quality of plants.
