Zusammenfassung: | The invention discloses a method for treating domestic sewage with a reinforced capillary infiltration trench system, which comprises the following steps of: pre-treating the domestic sewage in a hydrolytic acidification tank; and treating effluent after pre-treating in a reinforced capillary infiltration trench sequentially consisting of a soil layer, a sandy soil layer, an artificial soil layerand a water guide layer, collecting the effluent and discharging the effluent, wherein the soil layer and the artificial soil layer of the reinforced capillary infiltration trench are both inoculatedwith earthworm. The reinforced capillary infiltration trench system has strong impact resistance load capacity, the daily disposal capacity of the sewage is greatly improved, and the removal rate of CODcr, ammonia nitrogen and total phosphorus reaches over 90 percent. Under the condition of the current village and town sewage inflow water quality, the effluent can meet the requirements of the GB8978-1996 National Sewage Di |
