2022-12-12 13:38
With the acceleration of urbanization in China, the amount of wastewater discharged from cities has also increased, and China has paid more and more attention to environmental engineering wastewater treatment. Wastewater treatment can not only improve the reuse rate of water resources, maintain ecological balance, and beautify the urban environment, but also, to a certain extent, promote the development of water treatment technology in China's environmental engineering.
Aerator The application principle is mainly to treat wastewater in environmental engineering with aeration equipment, forcing it into the wastewater. The oxygen in the water moves rapidly, decomposing organic matter in the water, thereby achieving the purpose of decomposing oxides in the water.
So, cleaning Aerator What are the methods? Shandong Zhiyuan Environmental Engineering Co., Ltd. will explain it to you!
1. High-pressure air washing method - using a portable air compressor
Operating method:
Remove the hose connected to the aeration pipe or aeration disc and connect it to the air outlet of the air compressor. Operate the air compressor, paying attention to the inflation on the water surface, and then turn off the air compressor under normal conditions. When flushing with high-pressure airflow, pay attention to the various joints of the aeration pipe with hose clamps.

2. Acid washing method
Pour a 5% hydrochloric acid solution into the pool, place the clogged aeration pipe in the hydrochloric acid solution for about 12 hours, take it out and rinse it with clean water.
Microporous aerators are commonly used products in wastewater treatment. Regular cleaning is very necessary. It can not only improve the wastewater treatment effect but is also necessary for the equipment itself.
At the same time, the maintenance of the aeration head should not be ignored. Please do the following points.
1. After emptying the aeration tank, clean it with a brush or high-pressure spray gun;
2. Remove the aeration equipment from the aeration tank and clean it one by one.
3. An automatic cleaning device (formic acid) can be used during operation.

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
