摘要：
An experiment of colloid migration in the 10 m long vegetative filter strips under artificial rainfall conditions was made, and the colloid migration model of coupled rainfall were set up to explore the effect of rainfall intensity on the colloid migration through vegetation filter strips. The results show that under different rainfall intensity, the deposition and adsorption efficiency coefficient of the colloid in the vegetative filter strips decreased exponentially with the migration distance, and tended to be stable at location of about 6m. With the increase of rainfall intensity, the deposition and adsorption efficiency coefficient value of the colloid in the vegetative filter strips increased as a whole, indicating that the colloid removal effect under the larger rainfall intensity was better. © 2020, Editorial Board of Water Resources Protection.
