The utility model relates to an advanced biological wastewater treatment, an amplitude type and second-time mud absorption machine in a sedimentation tank , in particular to a leak proof exhaust mud device of the absorption machine, being characterized in that the device cut separately a rotational mud collection groove and a central tank which are communicated fixedly and rotational mud collection groove and the central tank exhausting mud through a hanging and crossing mud absorption pipe in communication that overcome the deficiencies of infiltration of waste water into an exhausting cylinder, diluting active sewage sludge caused by leaking which is because of rotating communication between an original central mud tank and central mud exhausting cylinder, and the device without any active elements has the advantage of using reliably hardly with maintenance and operating easily with a simple structure which cannot increase the cost.
