3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Refractory organic wastewater
Mainly organic pollutants, the five-day biochemical oxygen demand (BOD5) and chemical oxygen demand (CODcr) ratio of wastewater is less than 0.3.
3.2
Deep processing
After the front-end pretreatment, if the refractory organic wastewater does not meet the discharge standard, the process of further treatment is carried out.
4 Disposal methods
4.1 Advanced oxidation method
4.1.1 Fenton reagent oxidation method
4.1.1.1 Method summary
The Fenton reagent oxidizes large organic molecules into small molecules, and then oxidizes small molecules into carbon dioxide and water, and at the same time, the divalent iron is released
The iron ions are oxidized to ferric ions, and the ferric ions have a certain flocculation effect, and the hydrolysis of the ferric ions into iron hydroxide has a certain net trap
Role, thereby purifying water quality.
4.1.1.2 Process flow
After the wastewater is adjusted to pH 2~4 in the intermediate pool, it is transported to the Fenton oxidation tower (pool) by the Fenton feed pump, and the
The pollutants that are difficult to degrade in the wastewater are oxidized and degraded; the effluent from the Fenton oxidation tower (pool) flows to the neutralization tank by itself to adjust the pH of the wastewater to the middle
