Multidirectional three-dimensional circulation in-situ repair system

The utility model discloses a multidirectional three-dimensional circulation in-situ repair system which comprises a repair well and a monitoring well, and the repair well and the monitoring well arevertically installed on a site to be repaired at intervals. The monitoring well monitors soil characteristics, groundwater flow fields and pollution plume change data information of a site to be repaired, and the control part adjusts groundwater extraction and/or repairing agent injection of the repairing well to be carried out among different wells and different well sieve sections of the wells according to the obtained data information so as to promote multidirectional three-dimensional circulation of the groundwater and the agent. Pollution is efficiently removed along with water flow or areagent and pollutants are in full contact reaction. The multi-directional three-dimensional circulation in-situ remediation system provided by the utility model is reasonable in structure, intelligently and flexibly sets unde
