1. Experimental principles and purposes:

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 test uses the "--r floating"+"micro -electrolytic"+"UASB" processing process to deal with high -concentration industrial wastewater to achieve 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. With the anaerobic reaction in contact with sewage and sludge, biogas (m--nly methane and carbon dioxide) causes mud bed disturbance. 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.

Through the hope of this experiment, the following goals are achieved:

1. Master the general process of high -concentration industrial wastewater treatment;

2. Deepen the principle of understanding the experiment;

3. Understand the process and technical parameters of the experiment, and improve the theoretical and practical knowledge of students.

2. M--n technical indicators and parameters:

1. Environmental temperature: 5 ℃ ～ 40 ℃

2. Treatment of water: 5 ～ 12L/h

3. Adjust tank: HRT 3 ～ 5H

4, concrete pool: HRT 3 ～ 6H
