To the solution obtained after iron-carbon microelectrolysis, 1% by volume of hydrogen peroxide is added, and the pH value is adjusted to 8; the solution turns black without any precipitation occurring, after which polyester amide is added for flocculation

The raw water has a COD of 40,000 mg/L and a salt content of 20%–30%. After microelectrolysis using iron and carbon, hydrogen peroxide at a concentration of 1% by volume is added, and the pH value is adjusted to 8; the solution turns black without any precipitation occurring. Polyester amide is then used for flocculation, but the flocculation effect is poor. Does anyone know what the reason for this is?
Raw water components: sodium sulfate, sodium bisulfate, methanol, glycerin, fatty acids
