| 1 | This corresponds to the percolation phase of the drying mechanism. | |
| 2 | Clogging problem is often met in wastewater infiltration land treating systems. | |
| 3 | A test project of the subsurface soil infiltration system for rural domestic sewage treatment is built. | |
| 4 | However, as a kind of infiltration media , it played a important role in the treatment of wastewater. | |
| 5 | The factors of effluent NH3-N removal rate of wastewater land treatment was analyzed as an example of artificial rapid infiltration system. |
