Description
Technical Field
The utility model belongs to the technical field of high concentration organic waste water treatment, a high concentration organic waste liquid pyrolysis treatment process units is related to.
Background
The high-concentration organic wastewater is mainly derived from high-salt high-concentration organic wastewater generated in the production processes of garbage leachate, leather, printing and dyeing, pharmacy, food, chemical engineering and the like. Its advantages are high concentration of organic substances. COD is generally more than 10000 mg/L; secondly, the composition is complex, generally contains toxic organic matters, aromatic compounds and heterocyclic compounds, and also contains sulfides, nitrides, heavy metals, toxic organic matters and the like. Thirdly, the color is high and the odor is generated. Some waste water emits pungent and foul odor, which causes adverse effects on the surrounding environment. Fourthly, strong acid and strong base are contained.
The high-concentration wastewater treatment process device comprises physical treatment processes such as evaporation concentration, extraction and adsorption, chemical treatment processes such as strong oxidation, biological treatment processes such as activated sludge treatment and incineration oxidation treatment processes. For high-concentration organic waste liquid containing a large amount of inorganic salt, the organic waste liquid is difficult to remove by adopting physical chemistry and biological treatment, and for high-concentration organic waste liquid which is difficult to biodegrade, toxic and harmful and has COD of more than 10000mg/L and calorific value of more than 2000-3000 kcal, the incineration treatment is a reasonable process choice.
The incineration treatment of high-concentration organic waste liquor is a high-temperature oxidation process for decomposing organic matter into CO by means of combustion oxidation2And H2O, the reaction mechanism is as follows:
for example, the high-temperature oxidation reaction of organic matters in the wastewater is as follows:
C6H10O+8O2→6CO2+5H20 (1)
for example, the inorganic matter in the wastewater undergoes the following high-temperature oxidation reaction:
2NaoH+CO2→Na2CO3+H20 (2)
the main characteristics of waste water combustion are as follows: (1) the burning velocity is inversely proportional to the square of the droplet size. The finer the atomization of the liquid, the faster the combustion speed and the more complete the combustion. (2) When the temperature is higher than 900 ℃, the oxidation reaction speed of the waste water is high, and the burnout effect is good. And when the temperature is below 850 ℃. The oxidation reaction speed is weakened, the burnout effect is limited, and the atomization effect of the waste water is required to be better, so that the evaporation efficiency is improved, and the burnout effect is improved: the atomization effect depends mainly on the particle size distribution in the large particle range of the atomized droplets. (3) The waste water often contains some salts or secondary pollution precursors, so that necessary pretreatment and post-treatment are required in the incineration treatment. (4) The key element determining the incineration efficiency is the "3T + IE" principle. "3T + IE" refers to temperature, time, turbulence, and air excess factor.
The present waste liquid incinerator is a liquid jet incinerator, a rotary kiln incinerator and a fluidized bed incinerator, which are suitable for different situations.
The main defects of the incineration process are energy consumption and pollutants such as dioxin and the like generated in the combustion process.
