How should high concentration organic wastewater be treated?

Firstly, we need to know the characteristics of high concentration organic wastewater:

The first characteristic is the high concentration of organic matter, with COD generally ranging from tens of thousands to even hundreds of thousands of milligrams per liter;

The second is the complex composition, containing toxic substances, mainly organic compounds, aromatic compounds, and heterocyclic compounds, some of which also contain sulfides, nitrides, heavy metals, etc;

The third is high chromaticity, with an unpleasant odor, and some wastewater emits a pungent odor, causing adverse effects on the surrounding environment;

Fourthly, it has strong acidity and alkalinity;

What are the common treatment methods for high concentration organic wastewater?

The first one is the oxidation adsorption method. After the high concentration wastewater is adsorbed and released, it is preliminarily treated with magnesium powder for coagulation and adsorption. Then, advanced oxidation technology is used to catalyze oxidation, and then mold powder is used for coagulation and adsorption. The COD and chromaticity of the wastewater treated by this method can reach over 90%.

The second method is incineration, in which the pre treated boiling water is filtered under pressure and then sent to the top of the furnace arch, where it is sprayed into the furnace by a high-pressure air atomization nozzle for sugar evaporation and combustion. This process can thoroughly treat high concentration organic wastewater.

The third method is adsorption, which uses solid adsorbents with strong adsorption capacity to adsorb one or more components of wastewater onto the solid surface. The commonly used adsorbents include activated carbon and resin, which are difficult to regenerate and wash. Resin adsorption has a wide range of applications, good adsorption effect, and relatively high price.

The above are the commonly used treatment methods for high concentration organic wastewater by Jiajie Water Treatment, and the methods used for different types of wastewater are also different.
