Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a pharmaceutical laboratory wastewater treatment device. Background Art

[0002] Pharmaceutical laboratory wastewater refers to wastewater generated during the drug research and development, production or analysis process, which usually contains a variety of harmful components, such as organic solvents, heavy metals, drug intermediates, by-products and biological components.

[0003] In the process of treating pharmaceutical laboratory wastewater, flocculants are often needed to be added for precipitation. Flocculants can help aggregate suspended particles, heavy metals and other pollutants in the wastewater to form larger particles or precipitation, which is convenient for separation and removal. In the process of wastewater treatment, adding flocculants and other flocculation materials is one of the key steps. In order to ensure that the addition of flocculants can effectively aggregate suspended particles in the wastewater, it is usually necessary to determine the addition ratio of flocculants according to the concentration of suspended matter in the wastewater. For example, a new type of efficient cosmetic wastewater treatment equipment disclosed in publication number CN112978889A does not add flocculants according to the concentration of suspended matter in the wastewater during the wastewater treatment process. If the concentration of suspended matter is not accurately detected, the amount of flocculants added may be insufficient or excessive. If the flocculation input is too little, it will lead to incomplete flocculation, which will directly affect the precipitation effect. The amount of precipitation formed is small and may not meet the relevant emission standards. Excessive flocculation input will increase costs, and excess flocculants will not significantly improve the treatment effect, thereby affecting environmental protection and water quality safety.

[0050] The working principle of the present invention is as follows:

[0051] The wastewater to be treated and the flocculant to be added are connected to the water inlet 203 through a pipe and discharged into the mixing barrel 202. The first rotating driving member 217 is turned on to drive the first rotating column 218 to rotate. The rotating first rotating column 218 drives the hollow barrel 204 to rotate. During the rotation process, the hollow barrel 204 drives the telescopic stirring blades 206 to rotate to stir the wastewater and the flocculant to make them fully mixed. When it is necessary to detect the concentration of suspended matter in the wastewater, sampling is performed in the wastewater to be filtered. Usually, the sampling volume should account for a small proportion of the total volume, for example, 1% or less. The sampled wastewater is then discharged into the mixing barrel 20 2, the sample waste water entering the mixing barrel 202 will flow into the carrier box 306 through the discharge port 219 and filter the sample waste water through the glass fiber filter membrane 307. In the process of filtering the sample waste water, the glass fiber filter membrane 307 is weighed before and after filtering. During the rotation of the hollow barrel 204, the transmission column 302 is driven to rotate by the bevel gear pair. By turning on the controller, the clutch disk set inside the electromagnetic clutch 304 is attracted to drive the linkage column 305 to rotate. The rotating linkage column 305 drives the carrier box 306 and the glass fiber filter membrane 307 to rotate. During the rotation, the glass fiber filter membrane 307 will contact with the sliding The movable top block 313 contacts and squeezes the sliding top block 313 and the connecting block 314 to slide in the square frame 303 (it should be noted that the sliding top block 313 will contact and trigger the trigger sensor 319 during the process of being squeezed and sliding, and the trigger sensor 319 will be electrically connected to the controller to control the controller to control the clutch disk set inside the electromagnetic clutch 304 to separate for a set time (the separation time can be set by the controller) to prevent the carrier box 306 from rotating continuously). During the driving sliding process, the connecting block 314 will drive the square linkage frame 315 to move and engage with the gear ring 312 to rotate the rotating sleeve 308, and the rotating sleeve 308 will rotate. The sleeve 308 will drive the threaded rod 309 to rotate and rise inside it and drive the measuring element 310 and the limit lifting frame 311 to rise together. The measuring element 310 will rise to the inside of the carrying box 306 to lift the glass fiber filter membrane 307 and slide out of the glass fiber filter membrane 307. The measuring element 310 will detect the weight of the glass fiber filter membrane 307 at this time. After detecting the total amount of the glass fiber filter membrane 307 before and after filtration, the suspended residue remaining in the glass fiber filter membrane 307 is calculated, and the ratio of the suspended residue to the sample wastewater is calculated through the existing calculation program. Then, the ratio of the total amount of wastewater that needs to be added with flocculant is calculated according to the calculated ratio.

[0052] After the proportion of suspended solids is calculated, the required flocculant and wastewater are discharged into the mixing barrel 202 through the pipe fittings in proportion and evenly stirred, and finally discharged into the sedimentation tank 5. The weight of the wastewater discharged into the sedimentation tank 5 will drive the lifting plate 411 to slide downward in the sedimentation tank 5 and compress the fourth spring 410. The wastewater discharged into the sedimentation tank 5 from the discharge port 219 will impact the fan blade 404 to rotate the second rotating column 403. The rotating second rotating column 403 will drive the stirring fan blade 406 to rotate. The rotating stirring fan blade 406 will further stir the wastewater to fully mix the wastewater and the flocculant.

[0053] The existing wastewater flocculation temperature is 20-50℃. When using flocculants, these chemicals may react with suspended matter in the wastewater to produce exothermic or endothermic reactions. For example, when aluminum salts react with water, they may release heat, causing the water temperature to rise. This temperature rise may affect the subsequent precipitation and filtration processes and affect the treatment efficiency. Similarly, in some cases, the flocculant reacts with the solute to absorb heat, causing the water temperature to drop. The lower water temperature may affect the activity of the flocculant and thus affect the precipitation effect. The components contained in the wastewater of the pharmaceutical laboratory need to be added with different types of flocculants to mix with the wastewater. In the above-mentioned process of stirring the flocculant and the wastewater, different The type of flocculant is likely to generate heat increase or heat decrease when mixed with wastewater, resulting in the inability of sediment in the wastewater to flocculate and settle normally. By setting the bubble plastic 409, the bubble plastic 409 is fixed in the sedimentation tank 5 through the support frame 407 and the hollow tube 408 to contact the wastewater. When the heat is low, the air in the bubble plastic 409 may shrink due to the decrease in temperature, resulting in a smaller volume of the bubble plastic 409. Due to the decrease in volume, the overall density of the bubble plastic 409 may increase, resulting in a decrease in its buoyancy in water. When the heat is high, the air in the bubble plastic 409 will expand due to the increase in temperature, and the volume of the bubble plastic 409 will increase. As the volume increases, the overall density of the bubble plastic 409 may decrease, increasing the buoyancy. If the density of the bubble plastic 409 is lower than the density of water, it will rise in the tube. If the density of the bubble plastic 409 exceeds the density of water, it will sink in the tube. The floating and sinking thresholds of the bubble plastic 409 are preset. When the water temperature is lower than the set suitable flocculation temperature, the bubble plastic 409 sinks. The controller controls the second rotating drive member 413 to rotate. The rotating second rotating drive member 413 drives the connecting shaft 414, the square frame 415 and the heating and cooling element 416 to rotate, so that the heating surface of the heating and cooling element 416 rotates upward to increase the temperature. On the contrary, when the water temperature is lower than the set suitable flocculation temperature, the bubble plastic 409 sinks. When the temperature is higher than the set suitable flocculation temperature, the bubble plastic 409 rises, and the controller controls and drives the heating and cooling element 416 to rotate, so that its cooling surface rotates upward to reduce the heat. In the process of stirring the wastewater before it enters the sedimentation tank 5, the wastewater can be fully mixed to avoid uneven heat in the sedimentation tank 5, which leads to inaccurate detection. Traditional temperature sensors may have a certain delay, and the floating and sinking effect of the bubble plastic 409 can reflect the change of water temperature more quickly. The controller can respond immediately. By dynamically adjusting the heating power, it can avoid long-term overheating or low temperature. Compared with traditional methods, it has higher energy efficiency and reduces energy waste.

[0054] After the precipitated wastewater is discharged, the compressed fourth spring 410 will drive the lifting plate 411 to slide and rise in the sedimentation tank 5, and the rising lifting plate 411 will drive the pillar 214 and the slide bar 215 to rise. During the rising process of the slide bar 215, the inner wall of the block 212 slides to drive the block 212, the connecting rod 209 and the conical clamp 210 to move in the hollow barrel 204, and the conical clamp 210 squeezes the slide 207, and the squeezed slide 207 drives the telescopic stirring blade 206 to move on the limit baffle 206. 05 slides from inside to outside, and the telescopic stirring fan 206 comes into contact with the inner wall of the stirring barrel 202. In the process that the hollow barrel 204 is driven to drive the telescopic stirring fan 206 to rotate, the telescopic stirring fan 206 comes into contact with the inner wall of the stirring barrel 202, and the dirt attached to the inner wall of the stirring barrel 202 is scraped off, so as to keep the inner wall of the stirring barrel 202 clean and prevent dirt accumulation.
