RECIRCULATION TYPE QUASI-AEROBIC RECLAIMING CONSTRUCTION METHOD

摘要

PURPOSE:To perform the improvement in the quantity and quality of water, by returning and recirculating an exudate by utilizing the water channel provided to the normal plane of the side surface of a reclaimed land or the trench provided to the reclaimed land. CONSTITUTION:Rain fallen to a reclaimed land takes in the contaminant in garbage during the penetration in a garbage layer and simultaneously receive primary purification by biological decomposition due to bacteria and adsorbing and filtering effect due to soil to be gathered to an exudate gathering pipe 1 and flows in a pump well 2 by natural flow-down. A water pump 3 is provided to the pump well 2 and the exudate is sent to a recirculation pit 5 under pressure by level control. The exudate sent to the recirculation pit 5 under pressure is sent not only to a recirculation water channel 8 by a recirculation pump 6 but also to exudate treatment facilities by a raw water pump 7. The recirculation water channel 8 is packed with cobblestone or crushed stone. The exudate sent to the recirculation water channel 8 rises to a soil covering surface during a process naturally flowing down through the recirculation water channel to be evaporated and penetrated.
