An in-situ purification island structure and the construction method thereof, which refers to the field of sewage treatment technology. The in-situ purification island structure comprises the upstream purification island main body and the downstream purification island main body, in which the upstream purification island main body comprises the first base backfill layer, the first lower layer, the first hydrophobic layer, the first penetrating water layer and the first upper layer. The first ecological bags are set around the surface of the first base backfill layer. The first lower layer has center formed with a lower filling layer. The first hydrophobic layer has center formed with a hydrophobic filling layer. It has a good natural purifying effect on the sewage, saves the investment and cost, no limitation on the applications, the capacity and efficiency of the purifying is high, and saves the resource. 11211112131415. An in-situ purification island structure , characterized in that the structure comprises an upstream purification island main body () located on the upstream of a river and a downstream purification island main body () located on the downstream of the river; said upstream purification island main body ()comprises a first base backfill layer () , a first lower layer () , a first hydrophobic layer () , a first penetrating water layer () , and a first upper layer ();{'b': 11', '12', '11', '13', '12', '14', '13', '15', '14', '111', '11', '12', '121', '13', '131', '14', '141', '11', '121', '131', '141', '14', '15', '112', '1121', '15', '151', '2', '21', '22', '23', '24', '25', '21', '22', '21', '23', '22', '24', '23', '25', '24', '211', '21', '24', '25', '212', '25', '251, 'the first base backfill layer () is set on upper riverbed and parallel to horizontal plane of river water level.
