1. Tr--ning workbench

 

The workbench requires a dual -station structure design, and the industrial aluminum alloy profile framework is used, with a total of two floors. Among them, the ** layer can place m--ntenance tools, kits, and instruments; the second layer can be placed with a monitor with a 30W solar light and a cup of 30W solar lights. A fan. There is a drawer, two keyboard brackets, and two m--n cabinets, and there are four brakes below.

 

The power control screen is an iron double -layer sub -light dense -densely spraying structure, an aluminum panel. It m--nly provides 16 -way AC power socket interfaces, leakage protectors, and power supply instructions, which can provide work power supply for various instruments and equipment.

Triode measurement hole

1. Experimental principles and purposes:

1. Experimental purpose:

1. Strengthen the understanding of the operation method of integrated water biological treatment.

2. Master the measurement method of integrated water biological treatment.

3. Deepen the process and technical data of the device.

2. Experimental principle:

Use a combination of biological and materialized. The biological treatment uses the 40 polypropylene ball to flow the contact oxidation that is easy to flow. The two sink ponds use the oblique tube to settle the tank, and then filter and disinfect the standard of water in the water.

2. M--n technical indicators and parameters:

1. Environmental temperature: 5 ～ 40 ℃

2. Treatment of water: 0.3 ～ 0.5m3/h

3. Water inlet turbidity: 30 ～ 300mg/L

4. Water turbidity: 3 ～ 5m3/h

5. Device shape size: 1400mm × 500mm × 1500mm,

6. Work power: AC220V ± 10%, 50Hz, single -phase three -line system, power 800W, safety protection: ground protection, leakage protection, overcurrent protection

3. M--n configuration:

1. 1 original water tank: white PP plate material, 10mm thickness, 400 × 400 × 400mm, empty valve installed on the bottom plate, which is convenient for cleaning the water;

2. 1 water tank: white PP plate material, 10mm thickness, 250 × 400 × 400mm, empty valve is installed on the bottom plate, which is convenient for cleaning the water;
