Of course the contract effects of all factors mentioned relate to surfactant removal, which was significantly meaningful except the interaction of four factor effects (Time*method*H 2 O 2 dose*Fe 2+ dose) (P value<0.05).…”

The aim of our study was to investigate the effectiveness of Fenton and photo-Fenton processes for removing anionic surfactants from aqueous solutions. The study was conducted using 200 mgL and 120 mgL -1 ferrous ion) were 69.38 and 86.66%, respectively, which is consistent with the significant increase in the rate of LAS removal efficiency with reaction time (P<0.05). In conclusion, anionic surfactants removal was significantly correlated with reaction time by both methods, but showed less dependence on H 2 O 2 and Fe 2+ concentrations.

Phenol and ammonia are common pollutants in many industrial wastewaters. The partial nitritation and anammox process is a very promising technology for treating phenol–ammonia wastewater. This study was the first time to rapidly achieve the start‐up and operation of the single‐stage partial nitritation /anammox reactor treating phenol–ammonia wastewater. The optimized ratio of phenol and nitrogen (phenol/NH4+‐N=0.3) was set to start‐up the reactor. After 60 days of operation, the total nitrogen and COD removal efficiencies were around 73.0% and 79.5%, respectively. The activity of ammonium‐oxidizing bacteria was291.1 ± 3.0 mg NH4+‐N g−1MLVSS d−1 and the specific anammox activity was 20.9 ± 1.0 mg NH4+‐N g−1MLVSS d−1. The results indicated that the anammox bacteria had adapted to phenol condition and remained stable activity after the 60 days’ operation in the reactor. The sequence analysis of 16SrRNA showed that the microbial community structure evolved to a balanced distribution that the removals of phenol and ammonia could be achieved simultaneously. Practitioner Points Phenol/N ratio of 0.3 was set to start up the single‐stage partial nitritation/anammox reactor. The single‐stage partial nitritation /anammox reactor was rapidly started up when treating the phenol‐ammonia wastewater. Total nitrogen removal rate and COD removal efficiencies could achieve to 73.0% and 79.5%, respectively. Microbial community structure evolved to stable distribution of which AOB, anammox bacteria, denitrification bacteria and heterotrophic nitrification bacteria coexisted.
