Laboratory Wastewater Treatment Equipment Process Selection:

The effluent from the acid-base neutralization pond then flows into the sedimentation pond. The sludge produced after the acid-base neutralization and other suspended solids in the wastewater are separated from the water through the hetero-directional flow in the sludge-water separator within the sedimentation pond.

The effluent from the sedimentation pond sequentially enters the ozonation unit, oxidizing large,难degradable organic molecules into low-toxic or non-toxic small molecules. The organic pollutants and NH3-N in the wastewater are oxidized and decomposed into harmful substances such as CO2, N2, and H2O. The wastewater is then subjected to UV ultraviolet disinfection and chlorine dioxide composite disinfection. The final effluent enters a multimedia filter, where fine suspended particles, trace metals, and minimal amounts of organic matter that were not removed are addressed. Part of them are removed through physical and chemical processes such as adsorption and interception by quartz sand and activated carbon with its vast pore structure and high specific surface area. The other part is degraded and removed by anaerobic, aerobic, and facultative bacteria in the microbial film attached to the activated carbon. The process of activated carbon interception and adsorption alternates with microbial degradation and desorption in an interlaced, alternating, and cyclic manner. At this point, the wastewater meets the standards for discharge into the sewage network.

Categorized by pollutant properties:

Based on the nature of the main pollutants in wastewater, it can be categorized into organic, inorganic, and biological laboratory wastewater. Organic laboratory wastewater includes commonly used organic reagents and samples, such as phenols, benzene, nitro compounds, etc. Inorganic laboratory wastewater primarily contains strong acids, strong bases, heavy metals, arsenic compounds, etc. Biological wastewater often originates from biological safety laboratories, with pollutants including culture media, culture substrates, and liquid biological specimens tested in the lab, such as blood, urine, sputum, vomit, etc. There are also a small amount of laboratory utensils and animal cage rinse water, with pollutants mainly consisting of pathogenic bacteria, free of heavy metal ions, with good biodegradability and a high content of pathogenic microorganisms.
