The application of tannins in water treatment mainly includes the following aspects:
Wastewater treatment flocculant: Tannin extract can be used as a flocculant for wastewater treatment. Studies have shown that flocculants made from wattle bark tannins modified through aminomethylation can significantly improve the treatment effect of tannery wastewater and increase the COD removal rate.
Water treatment descaling agent and anti-scaling agent: Tannin extract is used as a descaling agent for boilers, heat exchangers and automobile water tanks, as a flocculant for wastewater treatment and as a desulfurizer for gas purification. These uses have already reached industrial and commercial levels.
.
Tannin extract wastewater treatment: The treatment method of tannin extract wastewater includes collecting tannin extract wastewater, removing suspended solids, adding dicyandiamide formaldehyde resin for treatment, separating and obtaining the liquid components, adding dicyandiamide formaldehyde resin again for treatment, and then adding inorganic coagulant, and Adjust the pH value, and finally add flocculant to mix and separate to obtain reused water for disposal. This method reduces the color, suspended solids and other pollution indicators in tannin wastewater to the greatest extent. It has the characteristics of wide adaptability, light color of the effluent, low treatment cost, and good recyclability.
