The invention provides pump-free integrated wastewater deep treatment equipment, in order to solve the problems that current wastewater treatment equipment is large in occupied area, heavy in the energy consumption and the like. The equipment belongs to the technical field of wastewater treatment equipment, and comprises an adjusting tank, an anoxic tank, aerobic tanks, a secondary sedimentation tank, a sand filter and a clean water tank, wherein the sand filter is arranged in the secondary sedimentation tank, the adjusting tank is communicated with the anoxic tank through an adjusting tank stripping tube, the anoxic tank is communicated with the adjacent aerobic tank through an anoxic tank water passing hole in the bottom of an adjacent baffle plate of the anoxic tank and the adjacent aerobic tank, the third aerobic tank is communicated with the secondary sedimentation tank through a secondary sedimentation tank water passing hole in an adjacent baffle plate of the third aerobic tank and the secondary sedimentation tank, the secondary sedimentation tank is communicated with the sand filter through a sand filtration diversion trench, the sand filter is communicated with the clean water tank through a clean water tube, and the clean water tank is internally provided with a clean water tank stripping tube. According to the equipment provided by the invention, a plurality of wastewater treatment tanks are developed and designed into a whole, so that the occupied area is small, and the land source is saved, a gas stripping manner is adopted to replace a pump to provide power cycle, so that the energy consumption is greatly reduced, and through multilevel oxidation treatment, the wastewater treatment effect is increased.
