Abstract
Alcaligenes faecalisNo.4, which is capable of heterotrophic nitrification and aerobic denitrification was used to treat coking wastewater (CW) to remove high-strength of ammonium and phenol. First, the phenol-degrading ability of No.4 was verified and a synthetic medium containing lactate and phenol as carbon sources was subsequently applied to the No.4 culture. Both carbon materials were entirely utilized for the complete consumption of ammonium. Next a coking wastewater containing 400mg/l of phenol and 400mg/l of ammonium-nitrogen was treated by the No.4 culture. Both compounds were completely removed through the addition of 4g/l of lactate. The removal rate of ammonium was 1.1kg-N/m3/day which is several hundred-fold higher than that in conventional treatment system.
