Abstract

Abstract

The paper investigated the performance of cassava starch wastewater treatment by a self-developed ABIC ( anaerobic baffled internal circulation) ． The results showed that the removal rate of COD was over 80% when hydraulic retention time ( HＲT) was 20 ～ 24 h，influent COD concentration was up to 3 000 ～ 15 000 mg /L，and organic loading rate was 3 ～ 20 kg /( m3 ·d) ． The ABIC system was effective to resist influent impact，the most affordable VLＲ was 26 kg /( m3·d) and had a steady operation． This reactor was fit for seasonal starch production wastewater treatment by shortening restart period
