Wastewater Treatment in Laboratory Settings is an essential part of wastewater management in the medical field and general living. Activities within laboratories often generate wastewater containing chemical compounds and microorganisms that can pollute the environment if not treated properly.
Characteristics of laboratory wastewater:
Laboratory wastewater typically contains various hazardous substances, including:
- Laboratory testing wastewater: Includes blood, specimen samples, and chemicals used for analysis and preservation.
- Domestic and sanitation wastewater: This wastewater mainly contains high organic matter and substances such as COD, BOD, N, and P.
Impacts of laboratory wastewater on human health:
Wastewater from laboratories can cause serious health issues, including:
Effects on the nervous and respiratory systems:
- Substances like Chloroform, Benzene, Acetone, and Cyclohexane can cause headaches, dizziness, or difficulty breathing.
- Impact on eyes, nose, and throat: Solvents like chloroform, carbon tetrachloride, and crotonaldehyde can cause irritation and inflammation.
- Cancer risk: Chemicals like Toluene and Benzene can increase the risk of cancer.
Laboratory wastewater treatment system:
- Waste collection and disposal: Use pipelines to collect wastewater and storage tanks to dispose of large solid wastes.
- Conditioning: Maintain the pH and temperature of the wastewater.
- Chemical treatment: Use H2O2 to decompose organic compounds.
- Coagulation and sedimentation: Settle solids using PAC chemicals.
- Biological treatment: Remove N and P from wastewater through aerobic and anaerobic processes.
- MBR membrane filtration: Use ultrafiltration membranes to remove hazardous substances.
- Disinfection: Eliminate bacteria and fungi to ensure wastewater meets standards.
