While the rapid development of the chemical fiber industry brings economic benefits, it also faces the challenge of wastewater treatment. This type of wastewater has complex components, high concentrations of organic matter, and low biodegradability. Traditional treatment methods often prove inadequate. Against this backdrop, the IC tower (internal circulation anaerobic reactor) has gradually become a preferred solution in the chemical fiber wastewater treatment field due to its unique design and technological advantages.
The core of the IC tower lies in its internal circulation structure and anaerobic biological treatment mechanism. The reactor uses a three-phase separator to achieve efficient solid-liquid-gas separation, and the high-concentration sludge area at the bottom provides a stable environment for anaerobic microorganisms. The refractory organic matter in chemical fiber wastewater, such as polyester residues and dye intermediates, is gradually decomposed into methane and carbon dioxide under the action of anaerobic bacteria, while simultaneously reducing the chemical oxygen demand (COD). The internal circulation system enhances mass transfer efficiency through self-circulating water flow, avoids short-circuiting, and improves reaction rate and treatment load.
The IC tower demonstrates multi-dimensional adaptability to the characteristics of chemical fiber wastewater. First, its high volumetric load capacity can cope with fluctuations in the concentration of organic matter in wastewater. Especially during water quality shocks, the system's stable operation is maintained by adjusting the influent flow rate and sludge return ratio. Second, the biogas produced during the anaerobic process can be recycled and utilized to achieve energy conversion and reduce the company's carbon emission costs. Third, the compact design of the reactor saves space and is suitable for the layout of chemical fiber plants with limited space.
In practical applications, the operation and management of the IC tower need to be dynamically adjusted according to water quality characteristics. For example, a temperature control system maintains a mesophilic environment (35-40℃) to optimize microbial activity; online monitoring is used to track key indicators such as pH and alkalinity in real time to prevent acidification risks. In addition, regular sludge discharge and sludge activity testing can prevent sludge aging and ensure long-term treatment efficiency.
As an important technology in industrial wastewater treatment, the application of the IC tower in the chemical fiber industry not only solves environmental problems but also promotes resource recycling. With the integration of process optimization and intelligent control technology, its application potential will be further unleashed, providing technical support for the green upgrading of the textile industry chain.

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
