摘要: After swine wastewater (SW) was treated with adsorption-stripping stage, the concentration of NH 4+-N and Total phosphorus (TP) in SW significantly decreased from 598.04, 42.95 to 338.02, 8.36 mg L− 1, respectively. The concentration of heavy metals, especially Zn 2+(96.78%), decreased by the ion exchange of artificial zeolite (AZ). The acidification of SW could significantly improve the nutrient utilization efficiency and promote the growth rate of C. vulgaris due to the hydrolysis of macromolecular substances into smaller molecules …
