This project is set below the paving, and all other equipment is set below the paving.
2. Before installation, check the civil engineering. The size and specifications of the equipment concrete base plate shall be the same as those shown in the plan and installation drawings. The average bearing capacity of the foundation shall be above 20T/m2. The equipment is set below the floor, and the relative elevation of the foundation floor is the same as the height of the equipment. The excavation width around the foundation is more than 500mm beyond the edge of the foundation.
3. According to the installation drawing, align the position, and use the crane to lift the equipment box into position. In order not to make a mistake in the direction, accurately align the distance between each other (800mm), properly arrange the equipment, connect the pipes, and when connecting with engineering plastic pipe special adhesive, it is required that each joint is free of oil stains. After grinding with sandpaper, apply adhesive with a brush. After the adhesive layer is slightly dry, connect it. The connected pipe shall not leak. Weld the equipment base and the embedded steel plate on the foundation. After removing the welding slag, apply epoxy resin three times.
4. At the same time, according to the process requirements, install the dosing device, disinfection device and all pipelines according to the actual situation.
5. Connect the control lines of the control panel, the equipment, and the control panel and power supply. When wiring, make the direction of the blower and motor the same as the direction indicated by the blower.
Underground Integrated water treatment equipment Characteristics and difficulties:
Underground integrated water treatment equipment is a modular sewage biological treatment equipment, which is a sewage biological treatment system with biofilm as the main purification body. Anaerobic biofilter, contact oxidation bed and other biofilm reactors have large biological density, dirt resistance, low power consumption, stable operation, easy maintenance. This time, a small treatment is designed for a certain village to treat sewage produced in life. The quality of domestic sewage is complex, containing a large number of bacteria, viruses, parasite eggs and toxic and harmful substances.
Underground Integrated water treatment equipment Characteristics
1. Small size: Under the same pollution load conditions with a biological filler filling rate of about 32%, the MBBR moving bed biological treatment pool accounts for about 30%~50% of the conventional biological treatment pool.
2. High microbial biomass: The biofilm carrier is mobile. Due to the shear force of water and the friction force generated by the movement of the carrier, the biofilm on the surface of the filler naturally falls off. Part of the sludge flows out of the reactor with the effluent, and part of the sludge remains in the reactor, playing the role of activated sludge. The sludge concentration is 5 to 10 times that of ordinary activated sludge, and the purification function is significantly improved; the microorganisms are diversified, and the biological food chain is long, so it does not cause blockage, does not need backwashing, and generally does not need reflux. The head loss of the reactor is small.
3. Good denitrification ability: Nutrients, anoxic, and anaerobic environments are formed on the filler, and nitrification and denitrification reactions occur in one reactor, which has a good effect on the removal of ammonia nitrogen.
4. Good removal effect: The sludge concentration in the reactor is high, generally 5-10 times that of conventional activated sludge method, which can reach 30-40g/L. The organic matter treatment efficiency is improved. In addition, due to the action of filler and water, the mass transfer between gas, water and solid phases is good, the activity of biofilm on the filler is high, and the organic load and efficiency of the system are improved.

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
