[0002] The anaerobic ammonium oxidation (Anammox) process is an efficient biological nitrogen removal technology, which is particularly suitable for treating wastewater containing high concentrations of ammonia nitrogen, such as sludge dewatering filtrate, biogas slurry and certain industrial wastewater from sewage treatment plants; this process uses special microorganisms - anaerobic ammonium oxidizing bacteria to directly convert ammonia nitrogen (NH 4 + )and nitrite nitrogen (NO 2 - )into nitrogen gas (N 2 ), thereby removing nitrogen pollution in water and achieving resource recovery or harmless discharge of nitrogen.

[0003] When the existing biogas slurry treatment equipment is in use, the organic residues and waste liquids after biogas fermentation are collectively referred to as biogas fermentation residues, which are composed of two parts: solid and liquid. Some methods for treating biogas slurry will adopt constructed wetlands and land treatment, etc. Such treatment efficiency is low, and later manual operation is required to separate the biogas slurry and biogas residues, and the operation is relatively troublesome.

A sewage discharge pipe 101 and a sewage inlet pipe 102 are fixedly arranged on the biogas slurry treatment tank 1. Moreover, a tank cover 5 is detachably arranged on the top of the biogas slurry treatment tank 1. The tank cover 5 can be fixed on the top of the biogas slurry treatment tank 1 by bolts, buckles, or fasteners, etc. Here, we preferably choose a fastener, which is convenient for installation and disassembly and has reliable fixation. A handle is fixedly arranged on the top of the tank cover 5 to facilitate removing the tank cover 5 from the biogas slurry treatment tank 1. An exhaust pipe is fixedly arranged on the tank cover 5 to collect biogas. Valves are fixedly arranged on the sewage discharge pipe 101, the sewage inlet pipe 102, and the exhaust pipe. And a gasket is fixedly arranged between the bottom of the tank cover 5 and the top of the biogas slurry treatment tank 1 to improve the sealing effect between the tank cover 5 and the biogas slurry treatment tank 1. It further includes: a frame 2 is arranged to be lifted and lowered in the biogas slurry treatment tank 1. The frame 2 has a rectangular structure, and the outer wall of the frame 2 abuts against the inner wall of the biogas slurry treatment tank 1. And a driving part for driving the frame 2 to lift and lower is arranged in the biogas slurry treatment tank 1; a fixed frame 3 is arranged in the frame 2. A collection net box 301 is fixedly arranged at the bottom of the fixed frame 3. During use, the fermented substances in the sewage will fall into the collection net box 301. On the one hand, it is convenient to separate the biogas slurry and the biogas residue. On the other hand, the biogas residue can be taken out of the biogas slurry treatment tank 1 to improve the use effect. And the fixed frame 3 is fixedly connected to the frame 2 through a connecting part. Lifting rods 302 are fixedly arranged at the top of both ends of the fixed frame 3. During use, by arranging the fixed frame 3 on the frame 2 and then fixedly arranging the collection net box 301 on the fixed frame 3, on the one hand, after the treatment is completed, it is convenient to separate the biogas slurry and the biogas residue, and it is also convenient to take out the biogas residue from the biogas slurry treatment tank 1 to improve the use effect. On the other hand, when the frame 2 drives the fixed frame 3 and the collection net box 301 to lift and lower in the biogas slurry treatment tank 1, the biogas slurry can be stirred to accelerate the reaction speed.

[0024] Refer to Figure 4, the connecting part can use screws or buckles to fix the fixing frame 3 inside the frame 2. Here, we design the connecting part as follows: a pressing rod 7 is slidably arranged on the fixing frame 3. Among them, a first cavity 303 is opened in the fixing frame 3, a groove 701 is opened at one end of the pressing rod 7 extending into the first cavity 303, the inner bottom of the groove 701 is an inclined surface, a second cavity 304 is opened in the fixing frame 3, a limiting plate is fixedly arranged on the second cavity 304, a plugging groove 203 is opened in the frame 2, and a plug rod 8 is fixedly arranged on the limiting plate. The two ends of the plug rod 8 are respectively engaged and connected with the groove 701 and the plugging groove 203. Moreover, in order to ensure reliable connection, a first spring is arranged in the first cavity 303, the two ends of the first spring are respectively abutted against the pressing rod 7 and the first cavity 303, and a second spring is sleeved on the plug rod 8, the two ends of the second spring are respectively abutted against the limiting plate and the second cavity 304. When in use, when it is necessary to remove the fixing frame 3 from the frame 2, first press down the pressing rod 7. Under the action of the second spring, one end of the plug rod 8 slides into the groove 701, and the other end slides out of the plugging groove 203. At this time, the fixing frame 3 and the collection net box 301 can be taken out from the frame 2. On the contrary, after the fixing frame 3 is installed in place, pull up the pressing rod 7. One end of the plug rod 8 slides out of the groove 701 along the inclined surface of the groove 701 and abuts against the side wall of the pressing rod 7. At this time, the other end of the plug rod 8 slides into the plugging groove 203, realizing the fixing of the fixing frame 3 in the frame 2, preventing the fixing frame 3 from falling off the frame 2 during use and affecting normal use.

[0025] Refer to Figure 2 and Figure 3 , the driving part includes a screw rod 4. A sliding groove 103 is opened on the inner wall of one end of the biogas slurry treatment tank 1. The screw rod 4 is rotatably arranged in the sliding groove 103. A sliding block 201 is fixedly arranged on one end of the frame 2. The sliding block 201 is fixedly connected with the screw rod 4.

The guiding block 202 is slidably arranged in the guiding groove, which can further ensure the reliable sliding of the frame 2. When in use, by driving the screw rod 4 to rotate through the motor, the frame 2 can be lifted and lowered in the biogas slurry treatment tank 1 through the sliding block 201. During the lifting and lowering process, it has a certain stirring effect, which helps to accelerate the reaction speed.

Guide rods 601 are fixedly arranged at both ends of the extrusion plate 6. One ends of the two groups of guide rods 601 away from the extrusion plate 6 are respectively slidably connected to the box cover 5. Baffles 602 are fixedly arranged at the tops of the two groups of guide rods 601. The bottoms of the baffles 602 are abutted against the top of the box cover 5. And a third spring 603 is sleeved on the guide rod 601. The two ends of the third spring 603 are respectively abutted against the box cover 5 and the extrusion plate 6. During use, by arranging the extrusion plate 6 on the box cover 5, when the collection cage 301 rises, the extrusion plate 6 can press the biogas residues in the collection cage 301, which can improve the quality of solid-liquid separation and the working efficiency.
