AB  - Enhancing industrial sludge detoxification is of scientific and practical 
      significance in confronting urban development and stringent environmental 
      regulations. A strategy combining ultrasound (US) with the zero-valent 
      iron/EDTA/Air (ZEA) process was proven to be eco-friendly, being efficient in the 
      removal of toxic compounds from textile dyeing sludge in our previous studies. In 
      this paper, therefore, the detoxification effects of three advanced oxidation 
      processes (US, ZEA, US/ZEA) on textile dyeing sludge were comparatively evaluated 
      for the first time through alteration of the sludge's physico-chemical parameters 
      (e.g., macronutrients, heavy metals, and persistent organic pollutants) and 
      toxicity (plants and aquatic biota), by which the appropriateness of industrial 
      sludge's agricultural use was assessed. The results showed that US led to the 
      least alteration of the physico-chemical properties, and the treated sludge 
      became less biodegradable, as demonstrated by XPS. With ZEA treatment, persistent 
      organic pollutants (POPs) were degraded by oxidation, and heavy metals were more 
      leachable, leading to effective detoxification with a relatively low sludge dose, 
      but an excessive amount of EDTA would negatively change the fertilizing 
      properties of the sludge. However, the integration of US and ZEA could avoid this 
      situation, as US promoted the degradation of EDTA and POPs, thus causing the 
      least inhibition or even a noticeable stimulation of plant growth when the sludge 
      dosage was 7.5 t(dw)/ha (recommended dosage by the latest legislation in China). 
      Aquatic organism toxicity tests further confirmed that US/ZEA treatment realized 
      the most significant toxicity reduction, leading to the slightest environmental 
      disruption. This study could be instructive in providing guidance for industrial 
      sludge management considering agricultural use.
