1) heavy metal-containing waste water is generated after the ettle that rainwater elution is washed away on ore mountain, by flowing to the foot of the hill at the top of massif,
It is collected by the annular for the being arranged at the foot of the hill band that catchments；
2) heavy metal-containing waste water that seepage flow goes out in massif is collected by the annular infiltration band that massif periphery is arranged in；
3) heavy metal-containing waste water in annular catchment band and annular infiltration band is transported to heavy metal adsorption within the walls by water pump,
Under the suction-operated of adsorbent material, the heavy metal in heavy metal-containing waste water is removed；
4) waste water after Adsorption heavy metal flows into water purifying tank, water outlet or introducing farmland irrigating in water purifying tank
Irrigate system.
Compared with prior art, the beneficial effects of the present invention are:
1) catchment band, annular infiltration band of annular can be constructed according to massif shape, and structure is simple, easy for construction, at low cost；
2) heavy metal adsorption wall has efficient removal effect to the heavy metal in heavy metal-containing waste water, and treatment effeciency is high,
Effect is good；
3) water purifying tank water outlet can introduce farm irrigation system, make full use of water resource；
4) any medicament is not added in system, there is no secondary pollutions may.
