Abstract
A processing method and system for the landscape sewage of an artificial hillside land. A back flushing tank and a biofilm purification room in the back flushing tank are positioned below the hillside of the landscape; the purification room is provided with a sewage layer, which is communicated with a water inlet pipe and a siphon pipe, a biofilm layer and a solid grid bracket in a top-down order. The sewage is discharged into the back flushing tank after being purified by the biofilm and is sent into a clean water pool outside the hillside through a water outlet. When the biofilm is plugged, the water level is elevated; the siphon is generated with the arrangement of a siphon assistant tube, a water jet device and an aspirant tube; the clean water reversely flows into the biofilm for the backflushing, which is automatically stopped through controlling the water level of the clean water surface. The system is positioned below the landscape hillside, which avoids the pollution of the land environment and satisfies the environmental protection requirement of the city. The landscape and the greenland can be the fallow land, the height of the hillside satisfies the required height space of the siphon tube. The removal amount of the chemical oxygen demand, the biological oxygen demand and the ammonia and nitrogen in the sewage reaches the standard through the purification of the biofilm. The backflushing of the siphon realizes the automatic circulation of the purification-siphon-backflushing-residue discharging-regeneration-repurification.
