The invention discloses enrichment and concentration equipment for preparing natural selenium-containing mineral water. The enrichment and concentration equipment comprises a percolation tower, a selenium enrichment device, a selenium concentration device, a first ultrafiltration device, a second ultrafiltration device, an acid-base neutralization tank and a selenium-containing concentrated solution storage tank, wherein the percolation tower contains multi-stage filler layers of selenium-enriched mineralization balls; the selenium enrichment device is used for adjusting filtered natural mineral water to be acidic; modified graphene oxide-chitosan microspheres are used for cyclic adsorption to enrich selenium ions in the mineral water; the first ultrafiltration device is used for performing ultrafiltration on selenium-enriched circulating water; the filtered circulating water is adjusted to be slightly alkaline by utilizing the acid-base neutralization box; and then the selenium-enriched modified graphene oxi
