Embodiment 1
[0032] This embodiment provides an in-situ synchronous repair system for industrial organic pollution sites, including a pumping system, a biochemical reaction system, a filter cloth filter system, an oxidation potential water generator, and a rinsing system connected in sequence. When the groundwater is input into the biochemical reaction system, the biochemical reaction system contains biological sludge for anaerobic and / or anoxic and aerobic treatment of the groundwater, and the filter cloth filter system is used to treat the groundwater through the biochemical reaction The groundwater treated by the system is filtered, the oxidation potential water generator is used to decompose the saline groundwater into acidic water and alkaline water, and the leaching system is used to spray the configured leaching solution to the soil.
[0033] It also includes a groundwater soil freezing system and a COD measuring instrument, the groundwater soil freezing system is used to cut off the...
Embodiment 2
[0062] This example provides a method for synchronously remediating soil and groundwater in situ at an organically polluted site. The specific steps are the same as those in Example 1. When the repair system is in working condition, the five small blocks are respectively rinsed with eluent A, eluent B, water or idle (because the time of water rinsing is usually only 1 / 2 of the eluent rinsing time, Therefore, there is a certain period of time after water rinsing, and the eluent C is leaching, water washing or idle state, which can simplify the complexity of operation.
