Hydrolysis-Aerotrophone Biotropic Experimental Device

1. Deepen the understanding of "printing and dyeing wastewater" or other wastewater.

2. Master the performance and testing technical data of this process, and use reliable data into production.

3. Make the operator improve theoretical and practical knowledge.

2. Experimental principle:

This device adopts the A/O method biochemical treatment process, which is two stages: hypoxic acidization and contact with oxidation.

After the sewage is removed from large particles and fiber -like impurities, it flows into the water tank (the large amount of water can be stirred by a fan), and then enters the acidification pool through the pump and measure the acidification pool for acidic hydrolysis. At this stage, the sewage is m--nly mass -quality. And using the characteristics of short -generation oxygen generations, strong activity, and easy reproduction and growth, the large molecular structure organic objects that are not easy to degrade into small molecules and soluble compounds, preliminary degradation of organic matter, and completing nitrification at the same time, and eventually eliminating nitrogen pollution.

Contact oxidation pool is a biological treatment device based on biofilm method -based and active sludge method. Through the aeration of oxygen oxygen, the organic matter in the sewage is fully exposed to the biofilm in the pool. The degradation function further degrades the small molecules and soluble compounds into carbon dioxide and water; then enters the vertical streaming two sinking pools to remove the peeled biofilm and active sludge, so that the water can reach the standard.

1. Product introduction

      The device is based on the physical object of the vehicle's external lighting system to fully display the structure and working process of the car's external lighting system.

It is suitable for the school's teaching needs for car lighting system theory and m--ntenance tr--ning.

2. Functional characteristics

1. Real and operating car external lighting system, fully display the composition of the car's external lighting system.

Manipulate various light switches to truly demonstrate the work process of the external lighting system of the car.

2. The teaching board panel adopts high -grade aluminum -plastic panels with strikes, pollution resistance, fire prevention, and moisture -proof, and spray -p--nted on the surface by special crafts; school students can intuitively compare the circuit diagram and physical objects, understand and analyze the working principle of the car lighting system. Essence

3. Detecting terminals are installed on the teaching panel, which can directly detect the electrical signals of the circuit components of the car's external lighting system on the panel, such as resistance, voltage, current, frequency signals, etc.

4. Demonstration panel parts use 1.5mm cold plate stamping and forming structure, beautiful appearance; the ch--n part is welded with steel structure, the surface is treated with spraying process, a self -locking wheel device, and a desktop on the base of the teaching plate. , Easy to place data, light detection instruments, etc.

5. The work of the teaching board adopts a normal 220V AC power supply, which is converted into a 12V DC power supply by transformed by the internal circuit. No battery is required to reduce the trouble of charging. The 12V DC power supply has a short circuit function.

6. Machinery assembly and fitter assembly virtual simulation software: This software is developed based on Unity3D. It can select 6 -level image quality. It has the design and virtual disassembly of the reducer and shaft structure, the design and simulation of common mechanical institutions, institutional resource libraries, institutional resource libraries,, institutional resource library, institutional resource bank, institutional resource library, institutional resource library, institutional resource library, institutional resource bank, institutional resource library, and institutional resource library. Typical mechanical institutions (virtual disassembly of gasoline engines), software is an overall software, which cannot be separate resources.
