The components of the embodiments of the present invention usually described and shown in the drawings here can be arranged and designed in various different configurations.

[0017] In the present invention, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0018] As Figure 1 shown, an anaerobic treatment system for coarse organic materials in this embodiment includes a collection pool 1 and a treatment container 2. A coarse material conveying member 15 is provided on the collection pool 1, and the coarse material conveying member 15 can be an auger; a scum covering member 14 is provided in the collection pool 1. The coarse organic materials are sent into the collection pool 1 through the coarse material conveying member 15. The coarse organic materials are located below the scum covering member 14, and the scum covering member 14 presses the coarse organic materials below the liquid level. After the initial decay of the coarse organic materials in the collection pool 1, a scum layer 16, a liquid layer 17, and a sediment layer 18 are formed from top to bottom.

[0019] The collection tank 1 is provided with a scum layer sewage cutting pump 3 and a sediment layer sewage cutting pump 4. The treatment container 2 is provided with a feeding auger 8 and a feeding pipe 9. The feeding auger 8 is connected to the scum layer sewage cutting pump 3 and the sediment layer sewage cutting pump 4, and the feeding pipe 9 is also connected to the scum layer sewage cutting pump 3 and the sediment layer sewage cutting pump 4. Valves 10 are provided at the outlet ends of the scum layer sewage cutting pump 3, the outlet ends of the sediment layer sewage cutting pump 4, the inlet ends of the feeding auger 8, and the inlet ends of the feeding pipe 9.

[0020] The sediment is sent into the feeding auger 8 and the feeding pipe 9 through the sediment layer sewage cutting pump 4, and the scum is sent into the feeding auger 8 and the feeding pipe 9 through the scum layer sewage cutting pump 3. The sediment and the scum are sent into the treatment container 2 for anaerobic treatment. During the anaerobic treatment process, the scum is pressed in the liquid by the top wall of the treatment container 2 and continues to rot and settle to form a sediment layer 18. The treatment container 2 is provided with a slag discharge pipe 13, and the sediment in the sediment layer 18 in the treatment container 2 is discharged through the slag discharge pipe 13.

[0021] The treatment container 2 is provided with a liquid discharge pipe 5. The liquid discharge pipe 5 is connected to a spray head 6 and a material flushing pipe 7. The outlet end of the material flushing pipe 7 is located in the collection tank 1, and the spray head 6 is arranged above the collection tank 1. At least one spray head 6 is provided. At least one material flushing pipe 7 is provided. In this embodiment, two material flushing pipes 7 are provided. One of the material flushing pipes 7 is located in the liquid layer 17 of the collection tank 1, and the other material flushing pipe 7 is located in the sediment layer 18 of the collection tank 1.

[0022] Part of the biogas slurry in the liquid layer 17 in the treatment container 2 is discharged through the liquid discharge pipe 5 and sent to the spray head 6. The spray head 6 sprays on the scum covering member 14 and enters the collection tank 1 to soak the coarse material organic matter. Part of the biogas slurry is discharged through the liquid discharge pipe 5 and sent to the material flushing pipe 7. The material flushing pipe 7 can stir the sediment layer 18 in the treatment container 2, facilitating the sediment layer sewage cutting pump 4 to send the sediment into the treatment container 2.

[0023] The top of the treatment container 2 is convexly provided with a gas collection chamber 11. The gas collection chamber 11 is provided with a gas collection pipe 12. A valve is also provided on the gas collection pipe 12. The biogas generated during the anaerobic fermentation process is collected through the gas collection chamber 11 and then transported to the biogas purification system for treatment and use through the gas collection pipe 12.

[0024] The collection tank 1 and the treatment container 2 can be connected and arranged, or as shown in Figure 2 In other embodiments, the collection tank 1 and the treatment container 2 are separately arranged.

[0025] The scum covering member 14 is a pressure film or a pressure grid. The coarse material organic matter includes straw, chicken manure, etc.

[0026] It can be understood that the scum layer sewage cutting pump 3 and the sediment layer sewage cutting pump 4 can be set simultaneously or only one of them can be set. The feeding auger 8 and the feeding pipe 9 can be set simultaneously or only one of them can be set.
