DY-246 Acidic Wastewater Variable Speed ​​Neutralization Tower Training Platform

Many industrial wastewaters often cont*n acidic substances, and the pH value of discharged wastewater should be between 6 and 9, so acidic wastewater should be treated by neutralization. When the neutralizing agent is granular, filtration is often used to make the acidic wastewater and the neutralizing agent fully contact, so that the pH of the wastewater turns to neutral. This experimental device is an experimental device that uses filtration neutralization method to neutralize acidic wastewater.

By directly observing the organic glass device, we can clearly understand the internal structure of the neutralization tower, the flow direction of wastewater and the working condition of the neutralizer. We can master the principle of acid-base neutralization and understand the relationship between the filtration rate and the acid wastewater concentration and the pH of the effluent.

2. M*n technical indicators and parameters:

1Ambient temperature: 5℃～40℃

2. Acidic wastewater in industry cannot be discharged directly. A conical organic glass tower is used, which is filled with dolomite or carbon stone (it is alkaline). When the acidic wastewater passes through, it will react with neutralization. The effluent must reach a pH value of 6 or above to meet the discharge standard.

3. The rising flow rate of wastewater can reach 40-70m/h

4. Processed water volume: 250～500L/h

5. Dimensions: Conical bottom diameter 100mm

6. Upper diameter 300mm

7. Height 1300mm

8. Device dimensions: 900 mm × 500 mm × 2100 mm

9. Working power supply: AC220V±10%, 50Hz, single-phase three-wire system, power 370W, safety protection: with grounding protection, leakage protection, overcurrent protection,

3. M*n configuration:

1. One raw water tank: made of white PP board, thickness 10mm, 600×450×600mm, with a dr*n valve installed on the bottom plate to dr*n the water;

2. Equipped with 1 raw water tank stirring motor , 1 set of 304 st*nless steel stirring paddle (power 6W, speed 120rpm), (including 1 speed regulator)

3. One set of acid wastewater neutralization tower: made of transparent organic glass, wall thickness 8mm, Ø 200mm×1200mm; water distribution system, etc.;
4. One anti-corrosion water pump, power supply: 220 V, power 370W, flow rate: 1m3/h, head: 15 (m),

5. Flow measurement and regulation: 1 rotor flowmeter (100-1000L/h)

6. Equipped with 1 set of filter material (filler height: 60-70% column height);

7. Power supply control system: 1 double-sided matte dense-gr*ned plastic-sprayed electric control box, leakage protector (Delixi brand), voltmeter, lockable push button switch, wire tube, etc.
