Abstract:
The detergent wastewater was treated by a twostage process of multifiller combined UAF/BAF, and the effect of the filtration rate on the treatment efficiency was investigated. The results showed that the average removal rates of COD, LAS and TP were 54%, 27%, 12% in UAF and 33.2%, 66.4%, 81.5% in BAF, respectively, when the filtration rate of the system was 1.4 m/h and the volume ratio of air to water in BAF was 2 ∶1. The average concentrations of COD, LAS, and TP in the effluent were 56 mg/L, 3.1 mg/L, and 0.5 mg/L, respectively, which all reached the first class standard in Integrated Wastewater Discharge Standard (GB 8978-1996). The results indicated that UAF improved the biodegradability of detergent industry wastewater, reduced the toxicity of LAS, and strengthened the BAF’s removal efficiency of refractory organics, LAS and TP. The problems in the treatment of effluent to satisfy the standards were solved.
