NOVELTY - Water inlet and outlet pipe net system for waste water high-efficiency land processing process, comprises water inlet pipe net including water inlet pipe, water inlet branch pipe and water distributing pipes, which are connected in sequence on one side of the land processing system, and water outlet pipe net which is equipped on the other side of the land processing system and provided with water collecting pipe branch pipe, water collecting head pipe and water discharging pipe, where there are multiple water distributing pipes vertically arranged, which get through e.g. biological filler.    USE - Used as a water inlet and outlet pipe net system for waste water high-efficiency land processing process.    ADVANTAGE - The system: improves the water distribution and water outlet manner; improves the volume utilization rate of the system; uses less pipe fittings to uniformly distribute water and discharge water, and thus the system reduces the investment cost; can be constructed in quick manner; and is simple, and has less pipe damage rate.    DETAILED DESCRIPTION - Water inlet and outlet pipe net system for waste water high-efficiency land processing process, comprises a water inlet pipe net including a water inlet pipe, a water inlet branch pipe and water distributing pipes, which are connected in sequence on one side of the land processing system, and a water outlet pipe net which is equipped on the other side of the land processing system and provided with a water collecting pipe branch pipe, a water collecting head pipe and a water discharging pipe, where there are multiple water distributing pipes vertically arranged, which get through biological filler, the water collecting layer and the water distributing layer. The water outlet pipe net is paved in the biological filler and the water collecting layer.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the water inlet and outlet pipe net system for waste water high-efficiency land processing process.
