| titleOfInvention | Method for treating DSD acid oxidative condensation wastewater |
| abstract | The invention provides a method for treating DSD acid oxidation condensation wastewater, belonging to the technical field of oxidation condensation wastewater treatment. The processing method comprises the following steps: (1) mixing reducing iron, inorganic acid and an activation stabilizer, and activating the reducing iron to obtain an acidic activation solution; (2) mixing the acidic activation solution with DSD acid oxidation condensation wastewater, carrying out reduction reaction, and carrying out solid-liquid separation to obtain a first filtrate; (3) adding a metal collecting agent into the first filtrate to obtain a collecting system; (4) and (3) carrying out decoloration flocculation treatment on the collecting system, and carrying out solid-liquid separation to obtain treated wastewater. The results of the examples show that before treatment, the DSD acid oxidation condensation wastewater is reddish brown, COD is more than or equal to 20000mg/L, the treated wastewater is clear and reddish, COD can be reduced to 4000mg/L, and the removal rate of organic matters is more than 80%. |
