ReviewCombination of Fenton processes and biotreatment for wastewater treatment and soil remediation

- The combination of Fenton process and biotreatment is novel and useful.
- Toxicity and biodegradability tests are significant to design a combined system.
- No matter which technology at first stage, they would be called combined methods.
- Wastewater contains PPCPs or EDCs.
- Use of combination system in wastewater and polluted soil.

There is a continuously increasing worldwide concern for the development of wastewater and contaminated soil treatment technologies. Fenton processes and biological treatments have long been used as common technologies for treating wastewater and polluted soil but they still need to be modified because of some defects (high costs of Fenton process and long remediation time of biotreatments). This work first briefly introduced the Fenton technology and biotreatment, and then discussed the main considerations in the construction of a combined system. This review shows a critical overview of recent researches combining Fenton processes (as pre-treatment or post-treatment) with bioremediation for treatment of wastewater or polluted soil. We concluded that the combined treatment can be regarded as a novel and competitive technology. Furthermore, the outlook for potential applications of this combination in different polluted soil and wastewater, as well as the mechanism of combination was also discussed.
