Laboratory waste liquid treatment equipment manufacturers offer customized low-temperature evaporators as per requirement. Quankun.

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

Process selection for laboratory wastewater treatment equipment:

The effluent from the acid-base neutralization pond then flows into the sedimentation pond, where the sediment produced after 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 pond.

The effluent from the sedimentation pond sequentially enters the ozonation unit, where large, non-degradable organic molecules are oxidized 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 is directed to a multimedia filter. Fine suspended particles, trace metals, and quantities of organic matter that have not been removed are partially eliminated through adsorption and retention by quartz sand and activated carbon with a 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 retention and adsorption alternates with microbial degradation and desorption in an intertwined, alternating, and cyclic manner. At this point, the wastewater meets the standards for discharge into the sewage network.

Fundamentals of Laboratory Wastewater Treatment Equipment Design

1. Source of Laboratory Wastewater: Comprehensive laboratory wastewater generated from pharmaceuticals, reagents, test solutions, instrument cleaning, etc.

2. Comprehensive laboratory wastewater composition: inorganic substances, organic substances, biological wastewater, etc.

1) Inorganic wastewater: heavy metal ions, acid-base pH values, halogen ions, and other non-metal ions.

2) Organic Wastewaters: Organic solvents, ammonia nitrogen, organic phosphorus drugs, etc.

3) Biological wastewater: viruses, chlamydia, mycoplasma, spirilla, fungi, Brucella, anthrax bacteria, etc.

The laboratory wastewater treatment system consists of units for wastewater classification collection, wastewater adjustment, advanced wastewater treatment, sedimentation separation, physical treatment, biological treatment, and comprehensive wastewater purification. It employs various treatment processes such as chemical pretreatment, chemical advanced treatment, inclined tube sedimentation, multi-stage disinfection and sterilization, filtration sedimentation separation, micro-electrolysis with high and low potential difference, electrochemical oxidation-reduction technology, two-stage organic biofilm purification, novel packed bed photo-catalytic reaction technology for organic wastewater, selective mass transfer of fresh liquid, and molecular imprinting technology on fungal hyphae surfaces to comprehensively treat organic, inorganic, and biological wastewater generated in the lab. This effectively removes COD, BOD, SS, color, and heavy metal ions from the wastewater. Different treatment technologies and control systems are used for wastewater treatment based on the composition of various laboratory wastewater types.
