IC Tower The Chinese name is Internal Circulation Anaerobic Reactor. It is a new type of anaerobic reactor following UASB and EGSB It has advantages such as large volume load, strong resistance to shock load, good water stability, large gas production, small sludge volume, low operating cost, and significant economic benefits. . Medium and high concentration wastewater treatment projects. When treating low and medium concentration wastewater, COD15 ~ 25kg / （ m ³ .d ），for medium and high concentration wastewater, it can reach 25-35kg / （ m ³ .d ) It integrates four main processes in the same reactor and achieves ideal treatment results. . The four processes include: liquid inlet and mixed water distribution system; fluidized bed reactor chamber internal circulation system; deep purification reactor chamber. The internal circulation system is IC the core structure of the reactor process, composed of primary and secondary three-phase separators, biogas lift pipes, gas-liquid separators, sludge and water drop pipes, biogas sealing chambers, etc.
IC Tower Working principle: First, by adjusting the generated wastewater pH value and temperature, the precursor enters the inclusion area at the bottom of the reflector, the anaerobic tower is filled with internal circulation sludge and water inclusions from the sludge discharge pipe, and then enters the granular sludge. COD The volume load of the oxygen tower with the biochemical degradation expansion bed area is very high, and most of the influent COD is degraded here, and a large amount of biogas is produced. As the liquid expansion work during the biogas bubble formation process occurs with gas stripping, the mixture of biogas, sludge and water rises along the biogas promoting pipe to the gas-liquid separator at the top of the reflector, where the biogas COD is separated from the water and exits the treatment system. The sludge and water inclusions flow down along the sludge and water down pipe into the inclusion area at the bottom of the reactor. After the water is filled with inclusions, the anaerobic tower enters the sludge expansion bed area, forming the so-called internal circulation. According to different influent COD load and different organs of the reflector, the internal circulation flow rate can reach 0.5-5 times the influent flow rate. After the wastewater is treated by the expansion bed, except for a part participating in the internal circulation, after passing through the primary three-phase separator of the process, it enters the granular sludge bed area of the fine treatment area for the remaining COD degradation and biogas production process, thereby improving and ensuring the effluent water quality. Because most of the chemical oxygen demand has been degraded, the chemical oxygen demand load in the treatment area is relatively low, and the gas production is relatively small. The biogas produced at this location is collected by the secondary three-phase separator and enters the gas-liquid separator through the process gas collector, and then is discharged from the treatment system. The wastewater treated by the anaerobic tower treatment area is impregnated by the secondary three-phase separator, and the supernatant is discharged from the effluent area, and the granular sludge returns to the sludge bed in the treatment area.

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
