Motor-free domestic wastewater automatic reclamation device

The utility model discloses a domestic wastewater automatic reclamation device. The inside of a box body comprises a wastewater inlet grid, a wastewater sedimentation grid, a microbe bed grid, a sludge discharge grid and a reclaimed water grid, wherein the wastewater inlet grid, wastewater sedimentation grid, microbe bed grid, sludge discharge grid and reclaimed water grid are mutually communicated through bottom holes; no filter is arranged between the sedimentation grid and the reclaimed water grid, thereby obtaining the reclaimed water from domestic sewage through ecological treatment; and the wastewater automatic reclamation device converts tap pipe pressure into power for pressure rise reclamation of reclaimed water in the tank. The utility model implements in-situ domestic wastewater biological treatment, and can automatic reclaim domestic wastewater without energy consumption of the motor.
