| titleOfInvention | Enzyme treatment process for organic wastewater containing thiol and thioether |
| abstract | The invention relates to an enzyme treatment process of mercaptan and thioether containing organic wastewater, which comprises the following steps: (1) adjusting the pH value of the wastewater, and adding peroxidase and hydrogen peroxide; (2) adding ferrous sulfate solution and hydrogen peroxide; (3) in the neutralization and degassing stage, a PAM solution is added after the pH is adjusted, and precipitation separation is carried out; (4) and (4) treating the wastewater treated in the step (3) in a sedimentation tank. On the premise of ensuring the treatment effect and the Fenton process, the method can obviously reduce the consumption of ferrous sulfate and hydrogen peroxide, thereby achieving the effect of reducing source sludge; the original Fenton process device is not changed, and the increase of the overall operation cost is not influenced; the invention also has the potential of further reducing the Fenton dosage, thereby reducing the sludge yield and lowering the operation cost. |
