Laying hen breeding wastewater recycling system

The invention relates to the technical field of wastewater recycling, in particular to a laying hen breeding wastewater recycling system which comprises an anaerobic tank, a feeding groove is fixedly mounted on the upper surface of the anaerobic tank, and a base is fixedly mounted on one side of the upper surface of the anaerobic tank. After a worker puts a microbial agent or a nutritional agent into an anaerobic tank through a feeding groove, the worker starts a motor, the output shaft end of the motor drives a threaded rod to rotate, and the rotating threaded rod drives a moving plate and a pressing plate to move in the direction of a vertical rod in a thread screwing-in mode; the pressing plate descends and is attached to the notch of the feeding groove, so that the notch of the feeding groove is covered by the pressing plate, external air is not prone to entering the anaerobic tank from the notch of the feeding groove, the interior of the anaerobic tank is sealed, the anaerobic environment in the anaerobi
