The working principle of the experimental device for degrading organic matters, which can prevent microorganisms from contacting and mixing with wastewater, provided by the utility model is as follows:

the first step is as follows: when organic matters in wastewater need to be degraded, a reaction tank 3 needs to be installed on a degradation tank 1, the reaction tank 3 is firstly inserted into the degradation tank 1, a fixing block 9 is abutted against a first ring block 8, then an operator manually controls a first rotating handle to rotate the first rotating handle to drive a first bidirectional threaded rod 18 to rotate, the first bidirectional threaded rod 18 drives extrusion plates 19 installed on different thread surfaces of the first bidirectional threaded rod to be far away from each other, the extrusion plates 19 cannot rotate due to the limit of a sliding rod, the extrusion plates 19 abut against a push plate 17 when moving, the push plate 17 drives clamping blocks 14 to be far away from each other and simultaneously extrude a first spring 15 until a T-shaped rod 11 can be inserted into a positioning groove 10, then the first rotating handle is rotated reversely to drive the first bidirectional threaded rod 18 to rotate, the first bidirectional threaded rod 18 drives the extrusion plates 19 to be close to each other, at the moment, the clamping blocks 14 abut against each other under the acting force of the first spring 15 until the T-shaped rod 11, the fixing work of the reaction tank 3 is completed;

the second step is as follows: when the wastewater is degraded, firstly, the first electromagnetic valve is opened, the wastewater containing organic matters is poured into the degradation tank 1 through the water inlet pipe 2, then, the second electromagnetic valve is opened, suspension liquid and liquid culture medium containing fungal spores are added into the reaction tank 3 through the charging hopper 4, then, after waiting for a period of culture, the fourth electromagnetic valve is opened, air is introduced into the reaction tank 3 through the pressure pipe 6 to pressurize the interior of the reaction tank 3, metabolic enzymes and culture solution generated by the fungi enter the degradation tank 1 through the filter membrane sheets 7 fixedly arranged at the bottom of the reaction tank 3 through pressurization, and are mixed with the wastewater containing the organic matters, then, an operator rotates the second rotary handle, the second rotary handle drives the rotary rod 30 to rotate, the rotary rod 30 drives a plurality of stirring paddles to rotate, so that the wastewater is uniformly mixed with the metabolic enzymes and the culture solution, and the organic matters contained in the wastewater are degraded, the degraded waste water is led out through a drain pipe, then new culture solution is continuously added into the reaction tank 3 through a charging hopper 4, fungal spores in the reaction tank 3 continue to grow and breed and produce metabolic enzymes for reutilization, and meanwhile, an oxygen adding pipe 5 is connected with an oxygen source. When the fungi in the reaction tank 3 are in the process of propagation and metabolism, the fungus culture solution can be temporarily added, and oxygen is intermittently introduced through the oxygen adding pipe 5 for propagation and utilization of the fungi;

the third step: when the filter membrane piece 7 needs to be replaced after reaching the service life after being used for a period of time, the pull rod is pulled at first, the pull rod drives the short plate 25 to move in the direction away from the second ring block 20 and simultaneously extrude the second spring 26, the short plate 25 drives the short rod 27 to move until the short rod 27 is separated from the groove 21, and then the filter membrane piece 7 is pulled down to disassemble the filter membrane piece 7, if the filter membrane piece needs to be installed, the reverse operation can be carried out.
