The treatment of landfill leachate with physico‐chemical and Fenton and Fenton‐like processes was investigated. Additionally, the acute toxicities of the raw, the physico‐chemical pre‐treated, and the Fenton and Fenton‐like oxidation treated leachates on activated sludge microorganisms are given (determined by the ISO 8192 (respiration inhibition test)). Pre‐treatment with lime positively affected the biodegradability of the sludge by preventing inhibition. The Fenton and Fenton‐like processes resulted in high chemical oxidation demand (COD) (>80%) removal performance from leachate samples. The inhibitory effects of the Fenton and Fenton‐like reagents on activated sludge mixtures decreased. In addition to toxicity, the COD removal efficiencies and the operation costs of the applied processes were determined.
