Microporous aerator It is necessary equipment for drainage and aeration oxidation. According to the usage, it can be divided into surface aerator and underwater aerator. Underwater aerators mainly include microporous aerators and jet aerators.
Compared with ordinary microporous aeration equipment, it improves the oxygenation efficiency and power efficiency of the equipment, simplifies maintenance, and can repair and replace damaged aeration equipment without affecting normal operation (uninterrupted water and air supply). Air device, uniform oxygen supply, high oxygen utilization rate, low energy consumption.
The diaphragm microporous aerator system is mainly composed of an aerator base, an upper spiral pressure cover, an air balancing plate, and a synthetic rubber diaphragm. Its constituent materials are made of engineering plastics. During assembly, only microporous rubber is needed. The rubber membrane is fitted onto the air balancing plate, placed in the aerator base with a sealing line, and then tightened with a screw cap.
The air pipe is made of polypropylene or ABS engineering plastic pipe (selected according to user needs), and is welded with a 3/4 inner thread connector. The microporous aeration head is directly screwed onto the air distribution pipe, which is simple to operate, install and use, and is conducive to maintenance and repair.
The diameter of the microporous aerator is D = 260mm (or 250): Type II D = 215mm (or 189). 2100-2500 open and closed holes are arranged on the synthetic rubber diaphragm according to certain rules. After inflation, the air enters evenly between the rubber diaphragms through the air distribution pipe. Under the action of air pressure, the diaphragm bulges slightly, and the holes are opened to achieve the purpose of air diffusion. When the air supply is stopped, the diaphragm pressure between the air flow plate and the air flow plate gradually decreases, so the holes gradually close. When the pressure disappears, the diaphragm is compressed on the airflow balancing plate due to the water pressure and the elasticity of the diaphragm itself.
Given the above structure and the good characteristics of the diaphragm itself, the mixed liquid in the aeration tank is impossible to flow back, so the holes will not be soiled. On the other hand, when the holes are opened, due to the elastic action of the rubber, a small amount of dust contained will not cause the gap of the aerator air gap to be blocked.

Practical application of IC tower in food processing wastewater treatment
Wastewater from the food processing industry contains a large amount of organic matter, suspended solids, and oils. Traditional treatment methods often face problems such as high energy consumption and long processing cycles. The IC tower (internal circulation anaerobic reactor), with its unique internal circulation structure and three-phase separation system, demonstrates technical adaptability in treating high-concentration organic wastewater. The core advantage of the IC tower lies in its internal circulation mechanism. Through the fluid movement of the internal rising and falling pipes, it achieves thorough mixing of sludge and wastewater, improving biodegradation efficiency. In food wastewater treatment, the IC tower can adapt to influent conditions with a wide range of COD concentrations, especially suitable for the dairy, meat processing, and brewing industries. Practice has shown that when treating oily wastewater, the IC tower can stably achieve a COD removal rate that meets emission standards by reasonably controlling the hydraulic retention time and organic load. In an actual engineering case, a large seasoning production enterprise used the IC tower as a pretreatment unit. The influent COD concentration ranged from 8000-12000mg/L, and after treatment by the IC tower, it was reduced to below 1500mg/L, significantly reducing the burden on the subsequent aerobic treatment unit. The operating data shows that the biogas yield of the IC tower is stable and can be used for energy recovery, further reducing treatment costs.
The effectiveness of IC tower in treating high-concentration organic wastewater
The IC tower (internal circulation anaerobic reactor) is an important piece of equipment in modern wastewater treatment, demonstrating significant technical characteristics in treating high-concentration organic wastewater. Its unique internal circulation system enhances the contact efficiency between sludge and wastewater, making the organic matter degradation process more thorough and showing clear adaptability in treating industrial wastewater with a COD concentration exceeding 3000 mg/L. The treatment effect of this technology is mainly reflected in two dimensions: organic matter removal rate and biogas production. Actual operating data shows that in wastewater treatment for industries such as brewing and food processing, the IC tower usually maintains a high COD removal rate. The granular sludge formed inside the reactor has good settling performance, ensuring the stability of system operation. When the temperature is controlled around 35℃, the microbial activity reaches an optimal state, and the treatment effect is relatively ideal. In the process of treating high-concentration organic wastewater, the volumetric loading capacity of the IC tower is a key indicator that distinguishes it from traditional anaerobic processes. Due to its multi-stage reaction zone design and internal circulation flow pattern, the equipment can withstand high organic load shocks. Pharmaceutical wastewater treatment cases show that the system can still maintain stable operation when the influent COD fluctuates between 5000-8000 mg/L.
In the back-end process of semiconductor manufacturing, the IC handler (integrated circuit testing and sorting equipment) plays a core role in verifying chip functions and screening for quality. Its working principle is to use a precision robotic arm to send wafers or packaged chips to the testing station, and use the probe card and tester to complete the electrical parameter measurement. Then, according to the test results, it automatically sorts out qualified products and defective products. This integrated "test-judgment-sorting" process makes it a decisive link in the quality control before the chip leaves the factory. From a technical perspective, the gatekeeping role of the IC handler is reflected in three dimensions: First, the contact testing scheme can simulate the actual working state of the chip and detect physical defects such as open circuits, short circuits, and leakage; second, the multi-station parallel testing architecture achieves the screening capacity of thousands of chips per unit time, matching the production capacity needs of the packaging and testing factory; more importantly, its test data is directly related to the yield statistics of the chip, providing key evidence for process improvement. Current mainstream equipment supports environmental temperature testing from -40℃ to 150℃, covering the reliability verification needs of different application scenarios such as consumer electronics and automotive electronics. In industrial practice, the testing standards of IC handlers are often more stringent than the terminal application conditions. Taking the case of a major packaging and testing factory as an example
