Abstract
Abstract
The study aims to improve the pollution control and eutrophication reduction in surface water by adding various materials and explore corresponding purification mechanisms. Methods: Six materials (H2O2, NaClO, persulfate, polyacrylamide, zeolite, and montmorillonite) were added into surface water. Different dosage combinations and treatment periods were arranged in the experiments. After the treatment, the contaminant removal performance was determined the water quality and toxic effects were analyzed. Results: The optimal dosages of the 6 materials were experimentally confirmed as follows: 0.3 mg/L H2O2, 0.03 mg/L NaClO, 5 g/L persulfate, 0.4 mg/L polyacrylamide, 20 mg/L zeolite, and 10 mg/L montmorillonite. The purification mechanisms involve chemical reactions and material adsorption. Conclusion: The combination of the 6 materials can be applied in surface water treatment as a green option.
