- Scope
- This standard specifies the method for the determination of chemical oxygen demand (COD) in high-chlorine and high-ammonia wastewater. This standard applies to the determination of chemical oxygen demand in the high-chloride and high-ammonia wastewater produced in the production process of oil refining catalysts and corresponding catalytic materials. Among them, the chloride ion concentration should not exceed 2 000 mg/L, the ammonium ion concentration should not exceed 1 000 mg/L, and the CODCr should be greater than 50 mg/L.
