I would not attempt to put this into French. However, here are some refs, if they are helpful..

First of all, there are many refs. in French academic tests to "Test Die-Away"...

IMHO I think it is important to mention "eau/x de riviere".

Also, isn't the "aerobic" bit referring to the "river die-away test".

i.e. test de die-away en eau de riviere en milieu aérobique.

Anyway, here are the refs. I don't really translate this sort of thing, but hope they help.

Abstract

Unacclimated and acclimated activated sludges were examined for their ability to degrade 4-CP (4-chlorophenol) in the presence and absence of a readily growing substrate using aerobic batch reactors. The effects of 4-CP on the micro (specific growth rate), COD removal efficiency, Y (yield coefficient), and q (specific substrate utilization rate) were investigated. It was observed that the toxicity of 4-CP on the culture decreased remarkably after acclimation. For example, the IC(50) value on the basis of micro was found to increase from 130 to 218 mg/L with the acclimation of the culture. Although an increase in 4-CP concentration up to 300 mg/L has no adverse effect on the COD removal efficiency of the acclimated culture, a considerable decrease was observed in the case of an unacclimated culture. Although 4-CP removal was not observed with an unacclimated culture, almost complete removal was achieved with the acclimated culture, up to 300 mg/L. The Haldane kinetic model adequately predicted the biodegradation of 4-CP and the kinetic constants obtained were q(m)=41.17 mg/(gMLVSSh), K(s)=1.104 mg/L, and K(i)=194.4 mg/L. The degradation of 4-CP led to formation of 5-chloro-2-hydroxymuconic semialdehyde, which was further metabolized, indicating complete degradation of 4-CP via a meta-cleavage pathway.

La méthode utilisée pour évaluer la persistance du diflubenzuron a été adaptée de celle
mise au point par D E KREUK (1976) et communément appelée " Die Away Test ". Ce test,
qui ne tient pas compte des phénomènes d'absorption et de dégradation qui peuvent avoir lieu
au niveau des matières en suspension et des sédiments, vise uniquement à connaître la stabilité
de la fraction solubilisée dans la phase aqueuse
