The utility model discloses a permeable adsorption type micro-polluted water treatment system. Characterized in that it is characterized in that it comprises, the device comprises a first-stage adsorption module, a second-stage concentration module and a third-stage electrolysis module, the primary adsorption module is composed of a composite filter element and a water permeable brick surroundingthe composite filter element; the secondary concentration module is composed of a water collecting funnel and a water collecting pipeline connected with the water collecting funnel, the water collecting funnel is communicated with the water permeable bricks and located below the water permeable bricks, and the tertiary electrolysis module is composed of an electrolysis treatment chamber which is installed in the water collecting pipeline and filled with iron-carbon filler. According to the utility model, sewage is directly recycled after being subjected to underground treatment by the underground micro-polluted water treatment system, energy is saved, a better sewage treatment effect is achieved through multi-means and multi-stage treatment such as physical adsorption, chemical precipitation, electrolytic treatment and the like, the cyclic utilization of municipal sewage is realized, and the energy is saved.
