Background
In order to meet the requirements of life drinking water, the development and utilization of groundwater has practical significance for inland water-deficient areas. Groundwater in some locations, however, typically contains arsenic and fluorine, and the coexistence of high concentrations of arsenic and fluorine water can cause arsenic and fluorine co-poisoning events.

The adsorption method has low cost, wide application and good fluorine and arsenic removal effect, plays an important role in treating fluorine-containing and arsenic-containing wastewater, and is particularly suitable for small-scale treatment and undeveloped areas. The existing adsorption method adopts adsorption materials such as activated carbon, ferric oxide, aluminum oxide, tiO2 and the like, and the adsorption materials have certain adsorption effect on arsenic and fluorine, but have limited adsorption capacity, and the pH value range suitable for fluorine removal is usually narrower (5-6), so that the difficulty in removing the arsenic and the fluorine together is increased.
Rainwater recharging is to irrigate surface runoff rainwater into the ground through various ways to balance groundwater environment. Rain water recharge is one source of potable water. However, due to the influence of urban environment factors and water collecting surface materials, urban rainwater is polluted to a considerable extent and contains toxic and harmful substances such as heavy metals, and the direct recharging is likely to pollute the underground water source, so that the surface runoff rainwater needs to be treated before the rainwater recharging.
