Embodiment 1

[0051] Embodiment 1: Electromagnetic synergy strengthens the method for purifying toxic and harmful organic pollutants in a biological packing tower. The specific operations are as follows:

[0052] 1. Coking wastewater is industrial wastewater containing a large amount of refractory organic pollutants. Its composition is complex, containing a large amount of toxic and harmful substances such as phenol, cyanide, benzene, ammonia nitrogen, etc. The coking wastewater discharged beyond the standard will cause serious pollution to the environment. Coking wastewater has the characteristics of large changes in water quality and quantity, complex components, high content of organic matter, especially refractory organic matter, and high concentration of ammonia nitrogen. Coking wastewater is industrial wastewater containing volatile phenols, polycyclic aromatic hydrocarbons, and heterocyclic compounds such as oxygen, sulfur, and nitrogen produced during the high-temperature dry distill...

Embodiment 2

[0063] Embodiment 2: Electromagnetic synergy strengthens the method for purifying toxic and harmful organic pollutants in biological packing towers. The specific operations are as follows:

[0064] 1. The treatment object of this embodiment is the same as the coking wastewater in embodiment 1, and the structure of the biological packing tower is also the same.

[0065] 2. The specific implementation method of this embodiment is as follows:

[0066] (1) Select the activated sludge in the coking wastewater storage tank of the coking plant as the initial strain, place the activated sludge in the culture device for aeration, add the diluted coking wastewater equal to the quality of the activated sludge to be treated, The diluted coking wastewater to be treated is prepared from wastewater to be treated and distilled water at a volume ratio of 1:100. At the same time, urea and disodium hydrogen phosphate are added as nitrogen and phosphorus nutrient solution, so that BOD in the enti...

Embodiment 3

[0073] Embodiment 3: Electromagnetic synergy strengthens the method for purifying toxic and harmful organic pollutants in biological packing towers. The specific operations are as follows:

[0074] 1. Printing and dyeing wastewater contains dyes, auxiliaries, oil agents, acids and bases, fiber impurities and inorganic salts, etc. It has the characteristics of large water volume, high chroma, strong alkalinity, and high organic content, and is an important source of water environmental pollution. With the development of modern printing and dyeing technology, a large number of new printing and dyeing auxiliaries, dyes, PVA sizing and other difficult-to-biodegradable organic substances are widely used in the printing and dyeing industry, resulting in enhanced stability of dyes in printing and dyeing wastewater, and organic components are becoming more and more complex. The B / C ratio decreases and the biodegradability decreases.

[0075] The amount of desizing wastewater in printi...

Abstract

The invention discloses a device and method for purifying poisonous and harmful organic pollutants by using an electromagnetic collaborative enhanced biological packed tower, and belongs to the field of pollution control of difficultly treated high-concentration poisonous and harmful organic pollutants. The method for treating the poisonous and harmful organic pollutants, which is disclosed by the invention comprises the steps: domestication of a bactericide; preparation of reactor packing; biofilm formation of reactor packing; and treatment of poisonous and harmful organic pollutants. According to the method disclosed by the invention, the defect that the degradation efficiency is affected by concentrated falling easily caused by aging when the biofilm process runs are overcome by utilizing an electromagnetic collaborative technology; the bactericide with a rapid growth rate and high degradation efficiency of poisonous and harmful organic pollutants is cultured; meanwhile, the content of dissolved oxygen in a reactor system is improved, so that the mass transfer rate of matter in gas and liquid phases is enhanced, and thus the degradation reaction probability of the poisonous and harmful organic pollutants is increased, and the organic matter is fully purified.

Description

technical field [0001] The invention relates to a device and method for purifying toxic and harmful organic pollutants, especially a device and method for electromagnetic synergistic strengthening based on biological packing towers to treat toxic and harmful organic pollutants, which belongs to the pollution of refractory high-concentration toxic and harmful organic pollutants control field. Background technique [0002] Toxic and harmful organic pollutants mainly refer to organic pollutants with biological toxicity. They not only have obvious toxicity to organisms and humans, but also can cause acute and chronic poisoning. Some toxic substances can also cause cancer, teratogenicity and genetic mutation of cells. That is, the "three-to" effect. Most toxic and harmful organic pollutants are artificially synthesized organic substances. Because of their large molecules and stable structures, they are difficult to be degraded by microorganisms in the natural environment and hav...
