Abstract:
The 2, 2-dimethylolbutanoic acid wastewater has the characteristics of high COD and high formaldehyde concentration. A treatment process of Formose polymerization+iron-carbon microelectrolysis+Fenton oxidation+coagulation precipitation+UASB+biological filter is used for wastewater treatment. Its process selection base, process flow, technological parameters and running efficacy are introduced. The results show that the COD and formaldehyde removal rate of the treatment process is over 98% and 99.9%, respectively. The COD and formaldehyde of effluent are less than 500 mg/L, 1.0 mg/L, respectively, which could meet the industrial park wastewater treatment plant takeover standard.
