[0002] Sludge treatment flocculants are agents used to treat industrial and domestic wastewater. Their main function is to aggregate fine suspended matter in wastewater into larger flocs and separate them from the water, thereby effectively reducing the water content in the sludge and alleviating the burden on subsequent treatment. Sludge treatment flocculants play an important role in sludge treatment and water purification. By rationally selecting and using the type and dosage of flocculants, the efficiency and quality of sludge treatment can be significantly improved, making a positive contribution to environmental protection.
