Research on artificial recharge of deep-seated groundwater——SPD artificial recharge system

The methods used to recharge groundwater by deep wells are adopted widely.Because of the tendency of being clogged and high requirement for water quality,the efficiency of recharge is decreased and correspondingly the cost of recharge operation is greatly increased.In this paper,a new method,SPD artificial recharge system,is put forward.Through simulation experiments in labs,the new method is compared with direct well recharge in the field.The results indicate that this new method is an effective way to recharge deep-seated groundwater with such characteristics as low requirement for water quality,high speed to recharge,large amount of recharge and anti-clogging,etc.
