The underground water pollution in-situ remediation reduces the ground treatment space for ex-situ treatment of pumped underground water, has strong remediation pertinence and wide application range, and is continuously increased in the practice of remediation engineering. Underground water circulating wells and in-situ zero-valent iron remediation techniques are common engineering techniques. The underground water circulating well technology aims at carrying out deep research on the aspects of synchronous repair of multiphase pollutants, optimized upgrade of a well body structure, intelligent regulation and control of hydrodynamic circulation, radius amplification of influence of a circulating well and the like. The development trend of the in-situ zero-valent iron restoration technology mainly focuses on the aspects of zero-valent iron adding mode, zero-valent iron reaction efficiency improvement, multi-technology coupling cooperative restoration and the like.
The underground water circulating well technology is mainly used for repairing volatile and semi-volatile organic pollutants, and has no obvious repairing effect on heavy metal pollutants. The in-situ reaction type circulating well repairing technology improves the heavy metal repairing effect of the circulating well through the physical and chemical properties of the filler, but the water pump is arranged in the circulating well, so that great difficulty is caused to the type selection and subsequent maintenance of the water pump. Therefore, the water pump is externally arranged on the ground, the external water pump reaction type underground water circulating well device is developed, the problems of maintenance and type selection of the water pump are well solved, and meanwhile, the use cost is greatly reduced.
