“…Many treatment techniques to remove chlorophenols have been developed, such as adsorption (Ding, Li, Wang, Zhang, & Chen, ; Soliman, Albishri, Marwani, & Batterjee, ; Zhang, Zhang, Wu, Sun, & Li, ), biodegradation (Angelucci & Tomei, ; Arora & Bae, ; Beristain‐Montiel, Martínez‐Hernández, de María Cuervo‐López, & Ramírez‐Vives, ), electrochemical dechlorination (Arellano‐González, González, & Texier, ; Duan, Tian, Liu, & Chang, ; Sun, Wei, Hu, Wang, & Shen, ), and advanced oxidation processes (Babuponnusami & Muthukumar, ; Mustafa & Shihab, ). Biological treatment techniques are widely used in wastewater treatment and have various advantages such as low cost and high efficiency.…”

Using glucose as cosubstrate, activated sludge that could effectively biodegrade 40 mg/L 2‐chlorophenol was successfully domesticated in sequencing batch reactors. To acclimate the sludge, 2‐chlorophenol was increased stepwise from 0 to 40 mg/L. High‐throughput sequencing revealed that the microbial community richness increased during the first 5 days of acclimation to 5 mg/L 2‐chlorophenol and then decreased after another 20 days as 2‐chlorophenol was increased. The original sludge obtained from a water resource recovery facility had the highest microbial diversity. As the acclimation continued further, community richness and diversity both increased, but they decreased again, significantly, when 2‐chlorophenol reached 40 mg/L. Saccharibacteria_norank, Bacillus, Saprospiraceae_uncultured, and Lactococcus were the dominant bacteria. Bacillus and Pseudomonas were the main known chlorophenol‐degrading bacteria. WCHB1‐60_norank, Tetrasphaera, Comamonadaceae_unclassified, and Haliangium showed poor tolerance to 2‐chlorophenol. Higher bacterial tolerance to chlorophenols does not mean higher degrading capability. The degradation of chlorophenols was not positively correlated with the detected abundance of known 2‐chlorophenol‐degrading bacteria. Practitioner points Activated sludge that could effectively biodegrade 40 mg/L 2‐chlorophenol was successfully domesticated using glucose as cosubstrate in sequencing batch reactors. Saccharibacteria_norank, Bacillus, Saprospiraceae_uncultured, and Lactococcus were the dominant bacteria. Bacillus and Pseudomonas were the main known chlorophenol‐degrading bacteria detected in this study. The degrading capability and tolerance of bacteria to chlorophenols were relatively independent and the degradation of chlorophenols may be the synergistic effect of various bacteria.

“…Some of them are as follows: ozonation at elevated pH, ozone + hydrogen peroxide (O 3 /H 2 O 2 ), ozone + catalyst (O 3 /CAT), O 3 / UV, H 2 O 2 /UV, O 3 /H 2 O 2 /UV, and photocatalytic oxidation (UV/TiO 2 ). The main advantages of these methods are high rates of pollutant oxidation, flexibility concerning water quality variations, and small dimension of the equipment [6,7].…”

A B S T R A C TWastewater treatment for water reuse is one of the main concerns in oil refineries since it can lead to high economic and environmental benefits. This paper deals with treatment of an effluents of Shiraz oil refinery called Slops reservoirs effluent by means of ozone as an advanced oxidation agent. For this purpose, ozone is well dispersed at a dose of 5 g/h and effective transferred concentration of 2335 mg/L using a gas distributor into a semi-batch reactor containing 1 L of the wastewater. In order to determine the efficiency of the treatment, the removal percentage of COD and sulfide was selected as studying parameters. The effects of initial sulfide and COD concentrations, presence of UV light, initial pH, and temperature were investigated on the studying parameters. According to the obtained results, the highest removal rate occurred during the first 30 min reaction time. Also it has been observed that, for the initial sulfide concentration of 350 mg/L and the initial COD concentration of 975 mg/L, the ozonation process after 45 min resulted in 100% sulfide removal under optimum initial pH of 9.4 and optimum temperature of 15˚C and presence of UV light. While at the same conditions, 92% of COD removal has been achieved for 60 min ozonation. Also, water turbidity level significantly reduced during the treatment.

Taking glucose as co-substrate, the activated sludge which could effectively biodegrade 2-chlorophenol (2-CP) of 40 mg/L　was successfully domesticated after acclimation for 49 days in sequencing batch reactors. High-throughput sequencing (HTS) analysis revealed that the community richness initially increased for 5 days and then decreased after another 20 days with the increase of 2-CP. The original sludge obtained from water resource recovery facility had the highest diversity. At the beginning of acclimation, the community diversity decreased. With the acclimation going on, both richness and diversity of community increased, but decreased significantly when the concentration of 2-CP was increased to 40 mg/L. Saccharibacteria_norank, Bacillus, Saprospiraceae_uncultured and Lactococcus were the dominant bacteria detected in this study. Bacillus and Pseudomonas were the main chlorophenol-degrading bacteria. WCHB1-60_norank, Tetrasphaera, Comamonadaceae_unclassified and Haliangium had lower tolerance to 2-CP. Higher bacterial tolerance to CPs does not mean higher degrading capability. The degradation of CPs was not positively correlated with the abundance of known 2-CP degrading bacteria detected in this study.
