AI Technical Summary
Existing circulating well technology struggles to effectively expand the vertical circulation flow range when remediating DNAPLs contaminants, resulting in poor remediation outcomes. In particular, the high density and poor solubility of DNAPLs, coupled with the limitations of traditional circulating well structures, lead to long remediation times and high costs.
By setting guides in the circulation well to change the direction of water flow and make it flow vertically, and by adjusting the position and length of the lower screen section to be close to the substrate, high-pressure and low-pressure zones are formed, enhancing the vertical circulation flow range, and using inertia to bring DNAPLs into the circulation well.
Without altering the standard structure of the circulating well, the vertical influence range of the circulating water flow was expanded, improving the remediation efficiency of DNAPLs, simplifying the DNAPLs removal process, and reducing remediation costs.
