In aerator During operation, air is injected at high speed into the bottom of the aerator from the air intake pipe. Air, which has a much lower specific gravity than water, will rise rapidly with great momentum. Negative pressure occurs inside the aerator, approximately 1.5 times the air volume. The activated sludge and wastewater at the bottom of the tank are sucked into the aerator to complete the first effective mixing. During the high-speed rising process, the mixture of air, activated sludge, and wastewater generates a vortex through the rotating cutter to complete the second effective mixing. Then, the mixture is pulverized into micro-groups by a specially designed multi-layer cutter, and oxygen is forced to dissolve into the water to complete the third effective mixing. The oxygen-rich mixture is ejected from the aerator cylinder at a high flow rate, thus completing
uniform mixing.
No blockage: Traditional aerators have a large number of micropores on their surface to complete the gas diffusion function. Due to hydraulic resistance, gas is intermittently discharged. Sludge will flow into the aerator through the micropores in a short time. Over time, the formation of micropore blockage will lead to the paralysis of the entire aeration system. If the main body of this invention is removed, it is only a large-pore gas release port, and it is determined that this structure does not block.
Low energy consumption, energy saving: The aperture of traditional aerators is only a few hundred micrometers, and the larger gas resistance leads to high blower power and high power consumption; due to the blockage of air holes, the resistance gradually increases, reducing the fan load and increasing energy consumption. This will shorten the fan life. This invention is a large-diameter vent with low gas resistance and low power consumption, and it can maintain the initial airflow resistance throughout the year. The fan load is low, and the service life is long.
Simple installation and protection: When installing or repairing traditional aerators, it is necessary to stop the inflow of wastewater, drain the activated sludge in the tank, and clean the mud and water before installation. After installation, it is necessary to cultivate activated sludge from scratch, which is both laborious and time-consuming; bottom sediments easily release hydrogen sulfide, posing a safety hazard. This invention does not require drainage operations, only needs to be assembled with the pipes on the ground, lifted and placed in a water-filled pool with a crane, and the branch pipe can be easily and quickly connected to the aeration main pipe.

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
