Example Embodiment
[0011] Example 1:
[0012] The technology of the invention treats phenol-containing wastewater.
[0013] Add 100mL of 100mg / L phenol wastewater into a 250mL conical flask, under magnetic stirring conditions, adjust pH=3 by adding hydrochloric acid, and adjust the temperature to 30°C through a temperature control device, ventilate until the dissolved oxygen is 5mg / L, then The content of horseradish peroxidase (HRP) was 0.1 U / mL, the reduced co-catalyst coenzyme NADH was 0.1 mmol / L, and the reaction time was 10 min.
[0014] After treatment, the removal rate of phenol is greater than 98%, and the removal rate of COD is greater than 90%.
Example Embodiment
[0015] Example 2:
[0016] The technology of the invention is used to treat wastewater containing pentachlorophenol.
[0017] Add 100mL of 10mg / L pentachlorophenol wastewater into a 250mL conical flask, adjust pH=5 by adding acetic acid under the condition of magnetic stirring, and adjust the temperature to 20°C through a temperature control device, and let oxygen gas until the dissolved oxygen is 40mg / L , and then adding horseradish peroxidase (HRP) wastewater with a content of 0.02 U / mL, reduced co-catalyst coenzyme NADH with a wastewater of 0.02 mmol / L, and a reaction time of 30 min.
[0018] After treatment, the removal rate of pentachlorophenol is greater than 95%, and the removal rate of COD is greater than 90%.
Example Embodiment
[0019] Example 3:
[0020] The technology of the invention is used to treat indole-containing wastewater.
[0021] Add 100mL of 20mg / L indole waste water into a 250mL conical flask, under magnetic stirring, adjust pH=8 by adding sodium carbonate, and adjust the temperature to 40°C through a temperature control device, and ventilate until the dissolved oxygen is 10mg / L , and then adding horseradish peroxidase (HRP) content of 1 U / mL waste water, reducing co-catalyst vitamin C to 1 mmol / L waste water, the reaction time is 5min.
[0022] After treatment, the removal rate of indole is greater than 95%, and the removal rate of COD is greater than 80%.
