[0034] Further, the reactor box body 2 is made of a material resistant to acids, alkalis and corrosion.

[0035] Embodiment 2, a biological pretreatment reactor structure for high-concentration and high-salt pharmaceutical wastewater provided in this embodiment. An inlet device is connected to the top of the reactor box body, including a lift pump for introducing the wastewater into the reactor; an aeration device and a monitoring device are provided inside the reactor box body, and a feeding device is connected outside; a mixing device is provided at the bottom of the reactor box body; the aeration device consists of a blower and aeration heads for supplying oxygen to promote the growth of microorganisms and the degradation of wastewater; the mixing device includes a dissolved air tank and a sludge scraper for keeping the microorganisms and the wastewater in the wastewater in a uniformly suspended state; the feeding device is used for feeding highly efficient biological strains; the monitoring device includes an on-line dissolved oxygen analyzer, an on-line thermometer and an on-line pH meter for real-time monitoring of the key parameters in the wastewater treatment process. A drainage device is also provided at the bottom of the reactor box body for discharging the pretreated wastewater; through the reasonable arrangement of each structure, the biological pretreatment efficiency of the pharmaceutical wastewater can be effectively improved.

[0036] Specifically: The water inlet device 1 includes a lift pump 6 and a water inlet pipe. Pharmaceutical wastewater flows into the reactor box 2 through the water inlet pipe. The aeration device 13 is located inside the reactor box 2 and includes an aeration head 18 and a blower 7 connected thereto. The feeding device 11 is located in the reaction zone in the middle of the reactor box 2 and is used to put in highly efficient biological strains. The mixing device 16 includes a dissolved air tank 8 and a stirrer 12, and a paddle stirrer 12 is equipped in the reaction zone. The monitoring device 9 is located in the reaction zone in the middle of the reactor box 2 and includes an on-line dissolved oxygen meter 3, an on-line thermometer 4 and an on-line pH meter 5. The drain pipe 14 is located at the bottom of the reactor box 2.

[0037] Further, the water inlet pipe of the water inlet device 1 is provided with a lift pump 6 for adjusting the water inlet flow rate; the drainage device 10 includes a drain pipe 14 and a reflux pump 17, and the reflux pump is used to return part of the pretreated wastewater to the reactor to maintain the system stability.

[0038] Furthermore, by operating the lift pump 6 in the water inlet device 1, the water inlet flow rate is controlled to maintain the water level and water inlet speed of the system. Water enters the system from an external water source through the water inlet pipe. Then, the water flow enters the reactor box, which contains a catalyst and other reaction substances, and undergoes specific chemical conversions through reactions with water. The pretreated wastewater is discharged through the drain pipe 14. At the same time, part of the pretreated wastewater is returned to the reactor box by the reflux pump 17 to adjust the liquid composition, dilute or supplement reaction substances, and improve the reactor utilization rate.

[0039] Further, the aeration head 18 is a microporous aeration head for generating finer bubbles and improving the oxygen transfer efficiency.

[0040] Furthermore, the aeration head 18 is a microporous aeration head, which is designed with many tiny holes. These tiny holes generate smaller bubbles, thus improving the oxygen transfer efficiency. When the gas is released from the micropores, many tiny bubbles are formed, which have a larger surface area to volume ratio, enabling them to more effectively contact the dissolved oxygen in the water. This can provide sufficient oxygen supply to the biological community in the reactor or other processes that require oxygen.

[0041] Further, the feeding device 11 is connected with a strain pretreatment system for culturing and adaptively adjusting the highly efficient biological strains to enhance the degradation ability of the strains and their adaptability to high-concentration and high-salt environments.

[0042] Furthermore, the feeding device 11 is connected to a strain pretreatment system, the purpose of which is to cultivate and adaptively adjust high-efficiency biological strains. The pretreatment system undergoes a series of operations, including strain cultivation, adaptive adjustment, and optimization of growth conditions. The key objective of the strain pretreatment system is to enhance the degradation ability of the strains and their ability to adapt to high-concentration and high-salt environments. This is achieved by exposing the strains to high-concentration and high-salt environments. Under such conditions, the strains gradually adapt and develop adaptability, enabling them to degrade pollutants more effectively.

[0043] Furthermore, the sludge scraper 15 of the mixing device is used to regularly remove the sludge suspended at the bottom of the wastewater to maintain the cleanliness inside the reactor.

[0044] Furthermore, the sludge scraper 15 in the mixing device 16 is a device used to regularly remove the sludge suspended on the surface of the wastewater. The sludge scraper is usually located at the lower part of the reactor and is equipped with a scraper or blade. Its main function is to push the sludge on the bottom of the wastewater towards the sedimentation area or other collection facilities of the reactor by scraping at regular time intervals. By using the sludge scraper, these sludges can be effectively removed, thereby maintaining the cleanliness inside the reactor. This helps to improve the efficiency of the wastewater treatment process and reduce the risk of equipment blockage and failure.

[0045] Furthermore, an air flotation machine is provided inside the dissolved air tank 8 to inject gas into the reflux liquid to provide the necessary buoyancy to help separate the floating and sinking substances and improve the flocculation effect.

[0046] Furthermore, the dissolved air tank 8 is located above the wastewater reflux pipeline, and compressed air is injected into the wastewater in the dissolved air tank 8, the purpose of which is to form bubbles in the wastewater. These bubbles are further refined and dispersed in the dissolved air tank 8 to generate more micro-bubbles, and then they are pumped into the reactor tank 2. These micro-bubbles have a large surface area and can come into contact with the floating and sinking substances more effectively, providing stronger buoyancy and flocculation effect.

[0047] Furthermore, the on-line dissolved oxygen meter 3, on-line thermometer 4, and on-line pH meter 5 are used to achieve real-time monitoring and data recording of the wastewater treatment process.

[0048] Furthermore, the online dissolved oxygen meter 3, the online thermometer 4, and the online pH meter 5 are used to achieve real-time monitoring and data recording of the wastewater treatment process. The online dissolved oxygen meter 3 measures the dissolved oxygen concentration in the wastewater, the online thermometer 4 measures the temperature of the wastewater, and the online pH meter 5 measures the pH value of the wastewater. These instruments are connected to the monitoring center through data transmission, and the measured data is transmitted to the monitoring center for analysis and processing. Operators can monitor the key parameters in the wastewater treatment process in real time through the monitoring equipment, and perform data recording, alarming, and regulation, so as to promptly detect abnormal situations, optimize the treatment process, and improve the efficiency of wastewater treatment and the accuracy of water quality treatment.

[0049] Furthermore, the reactor box 2 has a material and structural design resistant to high-concentration and high-salt wastewater to ensure the stability and corrosion resistance of the reactor.

[0050] Furthermore, to treat high-concentration and high-salt wastewater, the reactor box 2 is made of corrosion-resistant materials, such as plastics or special alloys resistant to acids and alkalis and corrosion, and combined with a reasonable thickness and strength design to resist high pressure and high temperature. In addition, the reactor box may also contain a corrosion-resistant inner lining or coating and has good sealing performance to prevent wastewater leakage and environmental pollution.

[0051] Furthermore, the parts not described in detail in this application are the same as the prior art or are implemented using the prior art.

[0052] In summary:
