The invention discloses a sewage recovery and transportation device for a biochemical sewage treatment tank and relates to the technical field of sewage recovery and transportation devices. The sewagerecovery and transportation device comprises a mixing tank, a second water pipe and a coarse filter net. A stirring motor is installed above the mixing tank. A stirring shaft is installed below the stirring motor. A sedimentation tank is installed on the right side of the second water pipe. The second water pipe is located below the mixing tank. The front end of the sedimentation tank is providedwith a third water pipe. The middle of the third water pipe is connected to a forth water pump. The first and second water pipes cooperate so that the sewage generated in a dirt storage chamber is effectively introduced into the sedimentation tank and is circulated. The dirt storage chamber can effectively collect the sludge to facilitate centralized treatment on the sludge by the user. The coarse filter net can effectively prevent the sludge from being reintroduced into the sedimentation tank.
