Shanghai School Laboratory Wastewater Treatment Equipment - Durable and Robust, Low-Temperature Evaporator Manufacturer, Low Energy Consumption

The core function of the laboratory wastewater treatment unit is to remove or reduce harmful substances in wastewater to safe discharge standards through physical, chemical, and biological methods. Common treatment technologies include neutralization reactions, precipitation, filtration, adsorption, oxidation-reduction, and membrane separation. For example, for acidic or alkaline wastewater, neutralization is typically used, adjusting the pH value to between 6-9 by adding the appropriate alkaline or acidic reagents. For wastewater containing heavy metals, chemical precipitation can be employed, adding reagents like hydroxide to form insoluble precipitates of heavy metal ions, which are then removed by filtration or centrifugal separation.

When selecting a laboratory wastewater treatment facility, schools need to consider multiple factors. First is the characteristics of the wastewater, including the types, concentrations, volumes, and patterns of change in pollutants. For instance, wastewater from biological laboratories may contain pathogenic microorganisms, while that from chemical laboratories may be rich in heavy metals or organic solvents. Next is the treatment objective, which is the required discharge standards or reuse requirements. Different regions may have varying local standards, ensuring the equipment can meet these is crucial. Then there are economic factors, including the initial investment in equipment, operational costs, and maintenance fees. Lastly, the reliability and ease of operation of the equipment are key, especially for school laboratories lacking professional operators. Equipment with high automation and simple operation is more advantageous.

Application Fields

Laboratory wastewater treatment equipment is widely used in universities, colleges, research institutions, medical facilities, biopharmaceuticals, disease control centers, environmental supervision, product quality inspection, inspection and quarantine, drug inspection, blood stations, animal husbandry, hospitals, petrochemicals, and various laboratories and chemical analysis rooms. After treatment, the wastewater meets the first, second, and third standards of the Comprehensive Wastewater Discharge Standard [GB8978-1996]. The treated wastewater can be discharged into the municipal sewage network or reused through further treatment processes.

Laboratory wastewater contains acids, bases, organic pollutants, heavy metal ions, pathogenic microorganisms, with a wide range of pH fluctuations and high COD concentration. It is primarily divided into three major categories:

1. Organic Wastewater: Primarily sourced from laboratory reagents and solvents.

2. Inorganic Wastewater: Main sources include acidic and alkaline reagents, heavy metal reagents.

3. Pathogenic Biological Wastewater: Primarily originates from microbial culture, blood biochemical experiments, blood stations, disease control centers, etc.
