1. Physical method: mainly use the grid in the equipment, centrifugation, clarification, filtration, oil separation and other methods to separate the suspended solids or turbidity in the wastewater;
2. Chemical method: The laboratory wastewater treatment equipment uses acid-base neutralization, coagulation dosing, flocculation and sedimentation and other methods to remove inorganic or colloidal substances in wastewater;
3. Physical and chemical methods: use adsorption, redox, catalytic oxidation, photocatalytic oxidation, composite disinfection and sterilization technology, high and low potential difference micro-electrolysis technology, electrochemical redox technology and other physical and chemical methods in the equipment to remove inorganic substances in wastewater. Or organic matter and colloidal matter play the role of removal;
4. Biological treatment method: mainly through secondary organic biofilm purification, biofilm method, new bioreactor and other methods to treat laboratory wastewater.
1. Redox
Adding an oxidant or reducing agent to the equipment can oxidize or reduce the substances in the wastewater to harmless substances. Among them, the oxidant includes air, ozone, etc., mainly for the treatment of phenol, sulfur chromium, mercury, printing and dyeing, hospitals, etc Wastewater in industries such as
2. Electrolysis
After the laboratory wastewater is inserted into the electrode plate and energized, the charged ions contained in the wastewater can be converted into neutral atoms, and the use of power supplies, electrode plates, etc., is mainly for the treatment of wastewater containing chromium and cyanide, wool spinning and other wastewater;
3. Extraction
Add a water-insoluble solvent to the wastewater, so that the solute contained in the wastewater can be dissolved in the added solvent, and then use the relative density difference generated after the solvent and water are mixed, so that the solvent can be separated. The extraction agent is generally divided into: pulse sieve tray tower, butyl acetate, benzene, centrifugal extractor, etc., mainly for the treatment of phenol-containing wastewater.
1. After the PCR laboratory wastewater treatment equipment has been used for a period of time, it needs to be treated with sludge, and the discharge valve of the equipment needs to be opened to discharge the sediment into the sludge tank;
2. The self-priming pump in the equipment should be cleaned regularly to prevent the blockage of the suction pump device;
3. PCR laboratory wastewater treatment equipment must check whether the electrical appliances in the equipment system can be opened and closed normally before use, and can only be used until all qualified;
3. Before use, it is necessary to check the power supply, the liquid level of the medicine, and whether the main body of the equipment is abnormal before it can be used;
4. The user of PCR laboratory wastewater treatment equipment must establish a regular maintenance system and a pharmaceutical safety management system.
