Résumé
Benzethonium chloride (BZC) is an antibacterial compound with extensive applications in various anti-infective products. However, the feasibility of attaining partial nitrification of municipal wastewater using BZC has not been reported. In this work, BZC was used for the first time to attain partial nitrification. Batch experiments indicated nitrite oxidizing bacteria (NOB) was more vulnerable to BZC than ammonia oxidizing bacteria (AOB). When activated sludge was treated only once with 0.023 g BZC·(g MLSS)
