I. Properties and mechanism of action

Dicyandiamide formaldehyde resin decolorizing agent is an organic polymer flocculant with a strong cationic charge, which can form flocculent substances with negatively charged pollutants in wastewater. Its mechanism of action is mainly through neutralization, making the suspended matter and color substances in wastewater lose their stability, forming flocculent precipitates, thereby achieving decolorization and purification of wastewater.

II. Applications

1. Treatment of dyeing wastewater: Dicyandiamide formaldehyde resin decolorizing agent shows high decolorization and COD removal rate, which helps to improve the water quality of wastewater.

2. Treatment of petrochemical wastewater: Petrochemical wastewater contains high concentrations of oils and suspended solids. Dicyandiamide formaldehyde resin decolorizing agent can effectively remove oils and suspended solids, enabling wastewater to meet discharge standards.

3. Treatment of municipal wastewater: Municipal wastewater contains a large amount of suspended solids, oils, organic matter, etc. Dicyandiamide formaldehyde resin decolorizing agent can quickly and effectively flocculate and settle these substances, which is beneficial to subsequent biological treatment processes.

4. Treatment of electroplating wastewater: Electroplating wastewater contains various heavy metal ions. Dicyandiamide formaldehyde resin decolorizing agent can form insoluble precipitates with heavy metal ions, thereby achieving effective removal of heavy metals in wastewater.

5. Treatment of food industry wastewater: Food industry wastewater contains a large amount of suspended solids and organic matter. Dicyandiamide formaldehyde resin decolorizing agent can quickly remove these pollutants and improve the efficiency of wastewater treatment.

6. Treatment of pharmaceutical wastewater: Pharmaceutical wastewater contains a large amount of organic matter, suspended solids, and color substances. Dicyandiamide formaldehyde resin decolorizing agent can effectively remove these pollutants and improve the treatment effect of wastewater.

7. Treatment of pulp wastewater: Pulp wastewater contains a large amount of suspended solids, cellulose, color substances, etc. Dicyandiamide formaldehyde resin decolorizing agent can effectively remove these pollutants and improve the purification effect of wastewater.

8. Treatment of electronic industry wastewater: Electronic industry wastewater contains various heavy metal ions and organic pollutants. Dicyandiamide formaldehyde resin decolorizing agent can form insoluble precipitates with these substances, achieving effective removal of pollutants in wastewater.

9. Treatment of metallurgical wastewater: Metallurgical wastewater contains a large amount of heavy metal ions, suspended solids, and organic matter. Dicyandiamide formaldehyde resin decolorizing agent can effectively remove these pollutants and help wastewater meet discharge standards.

10. Treatment of wastewater from other industries: Dicyandiamide formaldehyde resin decolorizing agent can also be used in wastewater treatment from other industries, such as chemical, steel, and mining industries, to improve wastewater treatment efficiency.
