Contact oxidation pool training desk

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, initially degraded organic matter, and at the same time completed the nitrification effect. pollute.

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 made of a refurbished tractor 495 diesel engine fuel injection system, which fully shows the structure and work process of tractor diesel engine fuel injection system.

It is suitable for the teaching needs of school theory and m--ntenance tr--ning for diesel engine fuel injection systems.

2. Functional characteristics

1. The real -operated diesel engine fuel injection system, fully display the composition and working process of the fuel injection system of the diesel engine. The motor rotates high -voltage pumps to demonstrate fuel injection.

2. The panel adopts a ** aluminum -plastic plate with strike, pollution resistance, fire prevention, and moisture -proof, and spray primer on the surface by special crafts; the panel prints with color circuit diagrams that will never fade and a schematic diagram of the working principle; The work principle of real objects, understanding and analyzing the fuel injection system of diesel engine.

3. The detection terminal is installed on the panel. You can directly detect the electrical signal of the circuit component of the fuel injection system of the diesel engine on the panel, such as resistance, voltage, current, frequency signal, etc.

4. The panel part uses a 1.5mm cold plate stamping and forming structure, which is beautiful in shape; the bottom part is welded with steel structure, the surface is treated with a spraying process, a self -locking wheel device, and a desktop of about 40cm on the bottom of the teaching plate, which is convenient for convenience Place information, detect instruments, etc.

5. The work adopts a normal 220V AC power supply. The internal circuit transformer is transformed into a 12V DC power supply. 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 choose level 6 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, typical mechanical mechanisms (virtual disassembly of gasoline engine engines) The software is an overall software that cannot be separated by separate resources.

A. Turbine design and virtual disassembly interface can be selected from turbine sn--l pole cone gear reducer, second -level pilot gear reducer, conical cylindrical gear reducer, coaxial cylindrical gear reducer, cone gear reducer, first -class cylindrical, first -class cylindrical, Gear reducer.
