具体实施方式： Detailed ways:

下面结合附图和具体的实施例对本发明作进一步说明：The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

如图1所示：预处理池16通过进料管15与USR反应器14的底部连通，在该USR反应器的上半部分设有与二级发酵池10连通的溢流管21，在USR反应器14和二级发酵池10的底部分别设有与沼渣池11连通的排渣管12，在USR反应器14的顶部设有与二级发酵池10连通的导气管2，二级发酵池10顶部的贮气膜9通过沼气净化装置3向发电机提供沼气；该沼气净化装置由依次连通的贮气柜22、水封器4、脱硫器5、脱水器6、气体压缩机7以及高压贮气柜8组成。As shown in Figure 1: the pretreatment tank 16 communicates with the bottom of the USR reactor 14 through the feed pipe 15, and the upper half of this USR reactor is provided with the overflow pipe 21 that communicates with the secondary fermentation tank 10, in the USR The bottoms of the reactor 14 and the secondary fermentation tank 10 are respectively provided with a slagging pipe 12 communicating with the digester 11, and the top of the USR reactor 14 is provided with an air duct 2 communicating with the secondary fermentation tank 10. The secondary fermentation The gas storage membrane 9 at the top of the pond 10 provides biogas to the generator through the biogas purification device 3; The high-pressure gas storage tank is composed of 8.

在上述技术方案中，USR反应器14为升流式厌氧固体反应器，它是一种新型的专用于处理固体物含量较大的反应器，其构造特点是反应器内不设三相分离器和其它构件。工作时，含有有机物固体的废液从反应器的底部进入并逐渐浸漫过含有高浓度厌氧微生物的固体床，废液中的有机固体与厌氧微生物充分接触反应，有机固体被液化发酵和厌氧分解，约有50％的有机物被转化为沼气；沼气随水流上升具有搅拌混合作用，它促进了固体与微生物的接触。由于重力作用，固体床区有自然沉淀作用，比重较大的固体物(包括微生物、未降解的固体和无机固体等)被沉积在固体床下部，反应器内保持较高的固体量和生物量，从而使得反应器中的微生物和固体有较长的滞留时间。当液面超过固体床一定高度时，便可从池顶的溢出口通过溢流管溢出至二级发酵池中。在溢出口前设有可减少池内SS流失的挡渣板，它会在反应器液面形成一层浮渣层；在长期稳定运行过程中，浮渣层达到一定厚度后趋于动态平衡。另外，不断有固体被沼气携带到浮渣层，同时也有经脱气的固体返回到固体床区；由于沼气要透过浮渣层进入到反应器顶部的集气室，会对浮渣层产生一定的“破碎”作用，因此浮渣层不会引起堵塞。集气室中的沼气经导气管引出池外进入沼气贮柜。In the above technical scheme, the USR reactor 14 is an upflow anaerobic solid reactor, which is a new type of reactor dedicated to the treatment of relatively large solid content, and its structural feature is that there is no three-phase separation in the reactor devices and other components. When working, the waste liquid containing organic solids enters from the bottom of the reactor and gradually soaks through the solid bed containing high-concentration anaerobic microorganisms. The organic solids in the waste liquid fully contact and react with anaerobic microorganisms, and the organic solids are liquefied and fermented. Anaerobic decomposition, about 50% of the organic matter is converted into biogas; the biogas rises with the water flow and has a stirring and mixing effect, which promotes the contact between solids and microorganisms. Due to the action of gravity, there is natural precipitation in the solid bed area, and solids with large specific gravity (including microorganisms, undegraded solids and inorganic solids, etc.) are deposited in the lower part of the solid bed, and the reactor maintains a high amount of solids and biomass. , so that microorganisms and solids in the reactor have a longer residence time. When the liquid level exceeds a certain height of the solid bed, it can overflow into the secondary fermentation tank from the overflow port on the top of the tank through the overflow pipe. In front of the overflow outlet, there is a slag blocking plate that can reduce the loss of SS in the tank, which will form a layer of scum layer on the liquid surface of the reactor; in the process of long-term stable operation, the scum layer tends to dynamic equilibrium after reaching a certain thickness. In addition, solids are continuously carried by the biogas to the scum layer, and at the same time, degassed solids are returned to the solid bed area; since the biogas enters the gas collection chamber at the top of the reactor through the scum layer, it will generate Some "crushing" action so the scum layer does not cause clogging. The biogas in the gas collection chamber is led out of the pool through the air guide pipe and enters the biogas storage cabinet.

由于厌氧消化反应过程受温度影响很大，为了保证厌氧反应在冬季仍可正常进行，必须对系统实施整体保温措施，同时还需对USR反应器14进行增温处理：USR反应器14的罐壁采用装填有保温隔热材料的夹层结构，在该夹层中设置有与锅炉1连通的热水管20。锅炉1的燃料可采用经过净化处理的部分沼气。为了保证反应充分，在USR反应器14上设有能够使发酵液体充分混合的循环管19，该循环管上设有泵；同理，为了使液体充分混合，在二级发酵池10和预处理池16上均设有搅拌机13。为了避免杂物混入，在预处理池16入口处设有隔栅18；为了便于将沉积在预处理池16中的污泥排除，在该预处理池的底部设有排泥口17。Since the anaerobic digestion reaction process is greatly affected by temperature, in order to ensure that the anaerobic reaction can still be carried out normally in winter, it is necessary to implement overall heat preservation measures for the system, and at the same time, it is necessary to increase the temperature of the USR reactor 14: USR reactor 14 The tank wall adopts a sandwich structure filled with thermal insulation materials, and a hot water pipe 20 communicating with the boiler 1 is arranged in the sandwich. The fuel for the boiler 1 can be part of the biogas that has been purified. In order to ensure that the reaction is sufficient, the USR reactor 14 is provided with a circulation pipe 19 that can fully mix the fermentation liquid, and the circulation pipe is provided with a pump; in the same way, in order to make the liquid fully mixed, the secondary fermentation tank 10 and the pretreatment A mixer 13 is provided on the pool 16 . In order to avoid the mixing of sundries, a grille 18 is provided at the entrance of the pretreatment tank 16; in order to facilitate the removal of sludge deposited in the pretreatment tank 16, a sludge outlet 17 is provided at the bottom of the pretreatment tank.
