A hydrate-based zero liquid discharge method for high-concentration organic wastewater: resource recovery and water reclamation

Abstract High-concentration organic wastewater has become a great challenge for treatment due to its toxicity and non-biodegradability. Traditional water methods focus on removing or destroying pollutants rather than considering the high-concentration as resource. As an ambitious sustainability goal, resource recovery from achieve zero liquid discharge (ZLD) attracted widespread attention. Here, hydrate-based method is proposed treat textile facilitate reuse of dyes enhance reclamation. The mechanism interaction between hydrate was invested. results show that are rejected growing lattice concentrated in residual solution. This can max removal efficiency 93.6% production rate 80%. In range 0–2000 mg/L, concentration does not affect effect rate. dye be reused again. exhibits potential recovering clean while achieving ZLD.
