Study on the Degradation of Sodium Diethyldithiocarbamate (DDTC) in Artificially Prepared Beneficiation Wastewater with Sodium Hypochlorite
Table 1
Simple comparison of common oxidants.
Oxidants
Advantages
Disadvantages
Applicable
Ozone
Strong oxidizing ability, no other reaction by-products.
High equipment cost, toxic when high concentration.
Mainly used as supplement for other water treatment methods
Hydrogen peroxide
Strong oxidizing ability, wide range of application.
Preparation and storage process of the reagent is complicated, high treatment cost.
Suitable for the treatment of low concentration and small capacity of wastewater, used as a pretreatment or advanced treatment method for refractory organic wastewater.
Potassium ferrate
Extremely strong oxidizing ability, minor secondary pollution, quick reaction.
Relatively high cost of reagent, high requirement of storage environment.
A novel method of wastewater treatment, the flocculation performance of reduction product of Fe3+ or Fe(OH)3 can affect the beneficiation process.
Hypochlorite
Easy to use, low cost, wide range of application.
High requirement of storage environment.
The most commonly used method of wastewater treatment.
