As a core component of industrial wastewater treatment systems, the construction quality and commissioning level of IC towers directly affect treatment efficiency and operational stability. During construction, special attention should be paid to the bearing capacity and level calibration of the foundation. The curing period of the concrete foundation should meet the design requirements, and the deviation of embedded parts should be controlled within 3mm. A multi-point balanced force scheme should be used during tower hoisting to avoid local stress concentration leading to structural deformation.
Pipeline connection is a crucial aspect of construction. Flexible joints are recommended for the inlet pipe to buffer hydraulic shocks, and the water distributor installation should be coordinated with a laser level to ensure uniform distribution. The assembly of the three-phase separator must strictly follow the drawings, and the compression of the seals should be within the technical parameters. During anti-corrosion construction, after welding, penetration testing should be performed, and the epoxy coal tar coating thickness should not be less than the design value.
The commissioning process is divided into two stages: clear water commissioning and load commissioning. During clear water commissioning, the water distribution uniformity is verified by adjusting the inflow, and short-circuiting is observed. For activated sludge inoculation, well-conditioned anaerobic granular sludge should be selected, and the inoculation amount is recommended to reach 30% of the effective volume. In the initial stage, the upward flow velocity should be controlled within the range of 0.5-1.0 m/h, and the VFA/alkalinity ratio should be monitored daily. If this value exceeds 0.3, a buffer agent should be added promptly.
During the operational parameter adjustment phase, the organic load should be gradually increased to the design value, and the COD removal rate and biogas composition should be checked every 8 hours. When the methane content stabilizes at 55%-65%, the system is considered to have reached a stable operating state. During daily maintenance, regularly check the water seal level and the patency of the exhaust system, and conduct a corrosion assessment of internal components annually.
For the treatment of high-sulfur wastewater, the monitoring of hydrogen sulfide concentration should be paid special attention during commissioning, and the alkali solution replacement frequency of the biogas scrubbing device should be dynamically adjusted according to the measured data. When treating calcium-containing wastewater, the scaling of the water distribution pipeline should be checked weekly, and low-pressure acid washing should be used for maintenance if necessary.
IC tower
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
