A combined process of biological wriggle bed and ozone biological aerated filter was utilized to treat textile wastewater. Results showed that COD removal efficiency was almost 90.4%. The average effluent COD was 85.87 mg/L. The effluent colority was 64-32 times. This study indicated that the combined process is potentially useful for treating textile wastewater.

Biological Contact Oxidation

The performance of a pilot scale combined process of facultative contact reactor-biological contact oxidation and ozone biological aerated filter (FCR-BCO-O3-BAF) treating real textile wastewater was investigated in this study. During the operating period, the average influent and effluent COD concentrations were 737.0mg/L and 15.6mg/L, the influent and effluent color were 750 times and 10 times, with the total HRT being 43.3h. The average COD and color removal efficiency were 97.9% and 98.7%, respectively. And the effluent COD and color satisfied the discharge standards (grade-1) of water pollutants for dyeing and finishing of textile industry (China). In the operating conditions, HRT of O3-BAF was decreased, leading to an increase of the effluent COD concentration. In addition, under the facultative circumstance by micro aeration in the FCR, where the dissolved oxygen (DO) was maintained in the range of 0.1-0.3mg/L, the growth of sulfate reducing bacteria (SRB) was inhibited. This study is a significant attempt to apply the combined process of FCR-BCO-O3-BAF to textile wastewater treatment.

Aerated Filter

One effective bromoamine acid (BAA) degrading strain FL was isolated previously with the ability to use BAA as the sole source of carbon and energy. The strain FL was applied in a combined process of microelectrolysis (ME) and biological aerated filter (BAF) to treat the bromoamine acid wastewater, and the treatment efficiency was investigated. It was shown that when the influent CODcr was lower than 1000 mg L-1, and the total hydrolytic retention time (HRT) was 37.7 h, the removal rate of chrominance and CODcr could reach 95.3% and 77.3% respectively. Most of the chrominance was removed by the ME treatment, while the removal of CODcr is mostly owned to the BAF treatment. After long-term contact with the BAA wastewater, the strain FL became one of the predominent species in BAF. When the system was subjected to hydraulic loading shock, the strain FL ensured the efficient removal of chrominance and BAA.
