Technical Field

[0001] This utility model relates to the field of diagnostic reagent technology, and in particular to a treatment device for simulating wastewater from biochemical experimental samples. Background Technology

[0002] The production of reagent kits (especially biological diagnostic kits, such as nucleic acid detection kits and immunodiagnostic kits) involves various biochemical experiments to ensure the purity of raw materials, reaction efficiency, and product stability. This process also generates specific types of biochemical experimental wastewater. For example, sample simulation wastewater contains residual liquids simulating clinical samples (such as proteins, lipids, and electrolytes in simulated serum), and may contain small amounts of preservatives (such as sodium azide, which is highly toxic) or anticoagulants (such as EDTA). Currently, there is no complete device for treating such wastewater. Therefore, it is necessary to develop a treatment device for biochemical experimental sample simulation wastewater to address these issues. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a treatment device for simulated wastewater of biochemical experimental samples, which can effectively treat simulated clinical sample wastewater and reduce environmental pollution.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

A circulation pipe connected to the inlet and outlet pipes is provided outside the main body, and a circulation pump is installed on the circulation pipe. A sludge inlet pipe is provided on the bottom side of the main body, and a sludge outlet pipe is provided on the sludge inlet pipe. Multiple layers of packing material are provided inside the main body, with a sludge layer below each layer of packing material.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are:

[0013] The wastewater treatment device for simulating biochemical experimental samples includes a first reaction vessel connected to a wastewater conveying pipeline. The outlet of the first reaction vessel is connected to a second reaction vessel, which in turn is connected to a sedimentation tank. The outlet of the sedimentation tank is connected to a hydrolysis acidification device, which is connected to a filtration device. The outlet of the filtration device is connected to a disinfection device, and the outlet of the disinfection device is connected to a wastewater discharge pipeline. In actual production, wastewater enters the first reaction vessel along the wastewater conveying pipeline under the action of a pump. After adding a reagent (copper sulfate), the highly toxic substance (sodium azide) in the wastewater reacts with the reagent. The wastewater is then conveyed to the interior of the second reaction vessel, where it is treated with a flocculant. Protein particles, fats, and other impurities in the wastewater are flocculated. The wastewater is then conveyed to the sedimentation tank, where the sediment formed by settling is discharged. The supernatant wastewater enters the hydrolysis acidification device for further treatment, which effectively decomposes proteins and fats. The wastewater then enters the filtration device for further treatment. The separated wastewater then enters the disinfection device for further treatment, removing harmful bacteria and ice-borne microorganisms. Finally, the wastewater is discharged through the wastewater discharge pipeline. The above-mentioned treatment device is reasonably designed and can effectively remove toxic substances, proteins, fats and other organic impurities, as well as pathogens from wastewater, greatly improving the wastewater treatment efficiency.

[0014] The first reaction vessel includes a vessel body with an inlet and a dosing port at the top and an outlet at the bottom. The vessel body has an external jacket and an internal rotating shaft. One end of the shaft is connected to a motor, and multiple stirring rods with trapezoidal stirring blocks are mounted on the shaft. Wastewater and the reagent (copper sulfate) enter the vessel body. The heat transfer medium in the jacket provides the temperature required for the reaction. After the motor starts, it drives the stirring rods and trapezoidal stirring blocks to thoroughly mix the wastewater and the reagent, promoting the full contact and reaction of sodium azide in the wastewater with copper sulfate to form copper azide, thereby removing the sodium azide.

[0015] The second reactor comprises a vessel body with an inlet and a flocculant inlet at the top and an outlet at the bottom. The vessel body is externally jacketed and internally housed a rotating shaft. One end of the shaft is connected to a motor, and multiple square stirring plates with stirring teeth at their ends are mounted on the shaft. Wastewater enters the vessel body, and flocculant is added. Once the motor starts, it drives the stirring plates and teeth to mix the wastewater and flocculant, ensuring thorough contact between protein particles and fats in the wastewater and the flocculant. The heat transfer medium in the jacket provides the necessary temperature for flocculation. This design of the second reactor facilitates the combination of denatured proteins, lipid particles, and other solid substances with the flocculant, forming large flocs that are then removed.

[0016] The sedimentation tank consists of a tank body with an inlet at the top and a outlet at the bottom, and a drain on one side of the upper part of the tank body. Inside the tank body is a rotating shaft, one end of which is connected to a motor. Multiple stirring rods are located at the top of the shaft, and a conical shape is located at the bottom. Wastewater treated in the first and second reaction tanks then enters the sedimentation tank. After the motor starts, the electric rotating shaft, along with the stirring rods and the conical shape, rotates, causing the copper azide and flocculants to settle and be discharged.

[0017] The hydrolysis acidification equipment includes a main body with an inlet pipe and an outlet pipe on its top and bottom sides, respectively. A circulation pipe connected to the inlet and outlet pipes is located outside the main body, and a circulation pump is installed on the circulation pipe. A sludge inlet pipe is located on the bottom side of the main body, and a sludge outlet pipe is connected to the sludge inlet pipe. The main body contains multiple layers of packing material, with a sludge layer below each layer. Each packing layer contains a microbial layer, and a distribution plate with multiple distribution holes is located above the first packing layer. Wastewater enters the main body under the action of the pump, is evenly dispersed by the distribution plate, and then passes through multiple packing layers and the effective treatment of the microbial layer, achieving further decomposition of proteins and fats in the wastewater. Further treatment with sludge further decomposes organic matter. Throughout the entire process, the circulation pump and circulation pipes ensure the continuous flow of wastewater within the main body, further facilitating effective wastewater treatment.

[0018] Because the disinfection equipment is an ozone disinfection device, it can effectively remove pathogens from wastewater.

[0019] Because the filtration equipment is an ultrafiltration membrane filtration device, it can effectively remove large molecular substances. Attached Figure Description

[0024] In actual production, wastewater enters the first reaction vessel through a wastewater conveying pipe under the action of a pump. After adding a reagent (copper sulfate), the highly toxic substance (sodium azide) in the wastewater reacts with the reagent. The wastewater is then conveyed to the second reaction vessel, where it is treated with a flocculant to coagulate impurities such as protein particles and fats. The wastewater is then conveyed to a sedimentation tank, where the sediment formed by sedimentation is discharged. The supernatant wastewater enters the hydrolysis acidification equipment, where it is first evenly dispersed by a distribution plate, then passes through multiple layers of packing material and microbial layers for effective treatment, further decomposing proteins and fats in the wastewater. After sludge treatment, the organic matter is further decomposed. Throughout the process, the wastewater is circulated within the equipment via a circulation pump and circulation pipe, which further facilitates the effective treatment of the wastewater and decomposes proteins and fats. The wastewater then enters a filtration device for further treatment, and the separated wastewater enters a disinfection device to remove harmful bacteria and microorganisms before being discharged through a wastewater discharge pipe. The above-mentioned treatment device is reasonably designed and can effectively remove toxic substances, proteins, fats and other organic impurities, as well as pathogens from wastewater, greatly improving the wastewater treatment efficiency.

Each stirring rod 20 has multiple trapezoidal stirring blocks 21. Wastewater and the reagent (copper sulfate) enter the vessel body. The heat transfer medium in the jacket provides the temperature required for the reaction. After the motor starts, it drives the stirring rods and multiple trapezoidal stirring blocks to thoroughly mix the wastewater and the reagent, promoting the full contact and reaction of sodium azide in the wastewater with copper sulfate to form copper azide, thereby removing the sodium azide.

One end of the shaft is connected to a motor, and multiple square stirring plates 30 are mounted on the shaft, with multiple stirring teeth 31 at their ends. Wastewater enters the reactor body, and flocculant is added.

The heat transfer medium in the jacket provides the temperature required for flocculation. This second reactor design is reasonable, facilitating the combination of denatured proteins, lipid particles, and other solid substances with the flocculant to form large flocs for removal.

Inside the tank body is a rotating shaft, one end of which is connected to a motor. Multiple stirring rods 40 are located at the upper part of the shaft, and a conical body 41 is located at the lower part of the shaft. Wastewater treated in the first and second reaction tanks then enters the sedimentation tank. After the motor starts, the electric rotating shaft, multiple stirring rods, and the conical body rotate, causing the copper azide and flocculants to settle and be discharged.
