Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a groundwater recharge system based on a micro-nano bubble generator. Background Technology

[0002] When groundwater is contaminated, especially by organic pollutants such as pesticides, it spreads and migrates very easily. To treat contaminated water, ex-situ treatment after extraction is generally carried out. If the groundwater pollution is far from the treatment point and the degree of pollution is low, it can be treated on-site and then reinjected. This not only treats the water body but also replenishes the groundwater. How to carry out on-site treatment and ensure groundwater reinjection requires an integrated design. Utility Model Content
