Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1 As shown, this utility model provides a technical solution: an integrated laboratory wastewater treatment device, including a regulating water tank 2 connected to a laboratory drainage pipe 1. The rear end of the regulating water tank 2 is sequentially connected via a main pipe to a quartz sand filter 3, an activated carbon filter 5, an ultraviolet sterilizer 6, a backwash water tank 7, and a clean water tank 8. A raw water pump 9 for providing power is installed between the regulating water tank 2 and the quartz sand filter 3. A backwash pipe 10 is also installed on the backwash water tank 7, with its output ends connected to the quartz sand filter 3 and the activated carbon filter 5 respectively. A backwash water pump 4 is also installed on the backwash pipe 10, through which water from the backwash water tank 7 is discharged into the quartz sand filter 5. In filter 3 and activated carbon filter 5, water tank 8 is connected to storage tank 11 via branch pipe 15. Storage tank 11 in this application is equipped with potassium persulfate. The output end of storage tank 11 and the output end of water tank 8 are connected to municipal pipeline 12. Regulating water tank 2 is also connected to backwash water tank 7, water tank 8 and UV photo-oxidation activated carbon equipment 18 via branch pipe 17. This utility model utilizes the combination of ozone gas and ultraviolet light to enhance the decomposition of organic pollutants and inactivates them through chlorine resistance. Furthermore, the integrated laboratory wastewater treatment device of this device has the characteristics of strong treatment capacity, low cost, high treatment efficiency, and no new pollution to the water body.
[0022] This application utilizes quartz sand as a filter medium. Under certain pressure, water with high turbidity is filtered through a layer of granular or non-granular quartz sand of a certain thickness, effectively removing suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odors, and some heavy metal ions. Commonly used filter media include quartz sand, activated carbon, anthracite, and manganese sand, with a particle size greater than 20μm, ensuring that the effluent turbidity is less than 0.5 NTU and SDI ≤ 5. This guarantees the quality of the produced water and extends the service life of the equipment. The quartz sand filter removes most impurities and suspended particles.
[0023] The activated carbon filter of this application is a vertical container. The internal packing material is high-quality fruit shell activated carbon, and the bottom layer is pebbles or quartz sand. The manufacturing process includes two parts: dehydration and activation. This results in a unique porous structure, generating a large surface area and possessing strong physical adsorption capacity.
[0024] Activated carbon filters mainly have the following three functions:
[0025] It adsorbs some organic matter in water, including trihalides (THMs), with an adsorption rate of 60%.
[0026] It can effectively adsorb metal ions, remove color and odor.
[0027] Activated carbon adsorption can reduce the oxygen consumption (COD) of potassium permanganate from 15 mg / L (O2) to 2-7 mg / L (O2). Furthermore, due to the increased concentration of adsorbed particles on the surface caused by adsorption, it also acts as a catalyst. The main functions of activated carbon in advanced water treatment are: adsorbing organic matter, colloids, microorganisms, residual chlorine, odors, and some heavy metal ions; removing residual chlorine and trihalomethanes (THMs) from water; and other pollutants. This ensures the quality of the produced water and extends the service life of the equipment.
[0028] In this application, the regulating water tank 2 is connected to the ozone advanced oxidation tank 14 via a second pipe 16. The regulating water tank 2 is also connected to the backwash water tank 7 and the clean water tank 8 via the second pipe 16. The output end of the storage tank 11 and the output end of the clean water tank 8 are used to transport the treated water to the municipal pipe network 12 via an external drainage pump 13.
[0029] This application utilizes an ultraviolet (UV) sterilization device to kill bacteria, preventing contamination and ensuring the hygiene standards of the finished water. The UV sterilizer is fast, efficient, and effective, without altering the physical and chemical properties of the water, and does not introduce contaminants. Its sterilization rate can reach 99.99%. When sodium hypochlorite liquid is added to water, it instantly hydrolyzes to form hypochlorous acid and hypochlorite ions. Because hypochlorous acid is a very small, neutral molecule with no charge, it can rapidly diffuse to the surface of negatively charged bacteria (viruses) and penetrate through the bacterial cell wall into the bacteria. The strong oxidizing properties of hypochlorous acid destroy the proteins and enzyme systems on the bacteria and viruses, thereby killing pathogenic microorganisms.
[0030] Water treatment processes can generate volatile organic compounds (VOCs) or aerosols, and pollutants can be transferred into the air or solid phase. Changes in the concentration of micropollutants in the raw water or the addition of oxidants can also contribute to pollution. Activated carbon adsorption and ultraviolet sterilization technologies avoid the generation of byproducts and the transfer of pollutants, achieving high retention rates.
[0031] In summary, this device utilizes a combination of ozone gas and ultraviolet light to enhance the decomposition of organic pollutants and inactivates them through chlorine resistance. Furthermore, the integrated laboratory wastewater treatment system of this device has the characteristics of strong treatment capacity, low cost, high treatment efficiency, and no new pollution to the water body itself.
