Industrial wastewater treatment training desk

The m--n characteristics of high concentration organic industrial wastewater are: high pollutants, COD can reach tens of thousands or even hundreds of thousands of mg/L; complicated composition, often cont--ns toxic and harmful organic matter and heavy metals; Essence

This experiment uses the "--r floating"+"micro -electrolytic"+"UASB" processing process to deal with high -concentration industrial wastewater to meet the standard discharge.

Micro -electrolytic:

Micro-Electrolysis technology, also known as internal electrolytic, iron reduction, iron carbon method, zero-price iron method, iron chips filtering method and other technologies. It is a wastewater treatment technology widely researched and applied. It m--nly passes (1) oxidation and reduction response (2) original battery reaction (3) electrochemical enrichment (4) physical adsorption (5) concrete precipitation of iron ions to achieve disconnection ch--n of macromolecular organic matter, remove each in waste water Specifies, metal ions, adsorbing and cohesion of pollutants, and biochemicals of wastewater.

UASB: The lift -outdoor mud bed (UASB) reactor is the m--n anaerobic process for processing high concentrations that difficult to degrade wastewater. The wastewater to be treated was introduced to the bottom of the UASB reactor, and the sludge beds composed of flocculent or granular sludge flowing upward. ** A jealousy reactions occur in contact with sludge, which causes biogas (m--nly methane and carbon dioxide) to cause mud bed disturbances. Among the gas generated by the sludge bed, some are attached to the sludge particles, free --r bubbles and --r bubbles attached to the sludge particles rose to the top of the reactor, hitting the bottom of the --r -off baffle, which caused the attached --r bubbles Release, the sludge particles of the --r are settled back to the surface of the sludge layer. Free gases and gases released from sludge particles are collected in the gas collector at the top of the reactor. The liquid cont--ns some rem--ning solids and biological particles into the sediment room. The rem--ning solids and biological particles are separated from the liquid, and they fall back to the sludge layer by reflective plate.

Function:

1. Institutional assembly tr--ning;

2. Measurement and tr--ning of institutional parts;

3. Drawing tr--ning tr--ning for institutions;

Product parameters

1. Product material: aluminum alloy refined, use CNC machine tool refinement and produced through anode oxidation technology (do not accept rotation of rondrobin), each part must be installed in the aluminum alloy surveying box, and the buffer embedded material block;

2. In order to facilitate the safe surveying and mapping box size: about 365 × 265 × 120mm

3. Det--led configuration:

Standard components to surveillance and mapping screws and bolts, size tolerances and limit shafts, sets of the axis, the size of the hole tolerance and limit, and the two -dimensional engineering diagram of accuracy brackets and end covers, and the error recognition theory.

Occupational skills comprehensive integration tr--ning virtual simulation system:

The software in the software can be rotated, magnified, reduced, and translated at 360 °. There are general interactive buttons: return, homepage, help. All virtual simulation tasks are prompted, and the software automatically hooks after a task. There is an experimental task above the tool library

1. Basic three -dimensional (XYZ space coordinate icon is automatically rotated at the XYZ space coordinate icon.)

A. Graphic stereo: The experimental steps are divided into experimental tasks (text prompt tasks) -the construction model (the model in the drag and dragging tool library to the three -projection surface system, and automatically appear the projection, there is a prompt when choosing an error) - change the attitude (by passing the passage) Click on the up, down, left and right arrows) — Select the projection (enter the answer interface, select the 3D projection map completed at this time in 6 items)

B. Cutting three -dimensional: The experimental steps are divided into experimental tasks (text prompt tasks) -the construction model (the model in the drag and drag the tool library to the three -projection surface system, and automatically display projection) -The label projection situation (for the three -dimensional projection drawing calibration , Select the corresponding labeling symbols in 14 blank fences)
