It is characterized in that it includes a membrane bioreactor and an organic wastewater-degrading bacteria tank. The organic wastewater-degrading bacteria are solidified on an active carrier, and a connecting channel is provided between the membrane bioreactor and the organic wastewater-degrading bacteria tank. However, when the reactor is in use, the organic membrane is installed inside the reactor in the form of bolts, which makes it inconvenient to replace the organic membrane. It is necessary to remove the top cover of the reactor and then screw the bolts to complete the removal of the organic membrane, which increases the difficulty of replacing the organic membrane in the reactor and reduces work efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example 1:

[0022] See also Figure 1-6 : In this embodiment, a wastewater organic membrane bioreactor includes an outer shell 1 and a top cover 6. The top of the outer shell 1 fits with the bottom of the top cover 6. The bottom of the top cover 6 is fixed with a frame 7. The outer wall of the frame 7 is plugged into the top of the inner wall of the outer shell 1. The frame 7 can be separated from the top of the outer shell 1 by being forced upward. The top of the top cover 6 is connected to multiple reaction structures 2. The front and rear sides of the top cover 6 are respectively fixed with cylinders 8, and the inner walls of the multiple cylinders 8 are respectively connected to fixed structures 3.

[0023] The reaction structure 2 includes a first square frame 201 and a square plate 202. The outer wall of the first square frame 201 is plugged into the outer wall through-hole of the top cover 6. The first square frame 201 is made of rubber. The left and right sides of the first square frame 201 are respectively fixedly connected to the inner side of the square plate 202. The top of the square plate 202 is fixedly connected to a handle 203, which facilitates moving the square plate 202 upward. The inner wall of the first square frame 201 is fixedly connected to an organic film 204. The bottom of the outer wall of the organic film 204 is fixedly connected to a second square frame 205. The second square frame 205 is made of stainless steel and can provide a certain weight. The bottom of the square plate 202 is in contact with the top of the housing 1.

[0024] The second square frame 205 is inserted into the groove of the outer wall of the top cover 6 in the reaction structure 2. At this time, the second square frame 205 moves downward from the middle until the bottom of the second square frame 205 is in contact with the bottom of the inner wall of the shell 1. At the same time, the lower part of the outer wall of the first square frame 201 is plugged into the groove of the outer wall of the top cover 6. At this time, the organic film 204 is in a straightened state, and the bottom of the square plate 202 is in contact with the top of the top cover 6. It can be seen that the organic film 204 can be directly removed from the top cover 6, which reduces the operational difficulty of replacing the organic film of the reactor and improves work efficiency.

[0025] A first straight tube 4 is connected to the lower front side of the shell 1, and a second straight tube 5 is connected to the upper rear end face of the shell 1. The fixed structure 3 includes a bent rod 301 and a ring 302. The outer wall of the bent rod 301 is slidably connected to the inner wall of the cylinder 8. The bent rod 301 slides back and forth through the inner wall of the cylinder 8 under force. The front of the outer wall of the bent rod 301 is fixedly connected to the inner wall of the ring 302. A spring 303 is sleeved on the outer wall of the bent rod 301. The front and rear ends of the spring 303 are respectively fixedly connected to the outer side of the cylinder 8 and the inner side of the ring 302. After the ring 302 is forced to move outward, it rebounds by the elastic force of the spring 303, and the inner side of the bent rod 301 is plugged into the circular opening of the outer wall of the shell 1.

[0026] Working principle:

[0027] Wastewater organic membrane bioreactor installation:

[0028] The first straight pipe 4 is connected to the drain pipe, and the second straight pipe 5 is connected to the water inlet pipe. Then, the second square frame 205 is inserted into the groove on the outer wall of the top cover 6. At this time, the second square frame 205 moves downward from the middle until the bottom of the second square frame 205 is in contact with the bottom of the inner wall of the outer shell 1. At the same time, the lower part of the outer wall of the first square frame 201 is plugged into the groove on the outer wall of the top cover 6. At this time, the organic film 204 is in a straightened state, and the bottom of the square plate 202 is in contact with the top of the top cover 6.

[0029] Wastewater organic membrane bioreactor uses:

[0030] The wastewater enters the housing 1 through the second straight pipe 5 and contacts the organic membrane 204 . At this time, the wastewater reacts with the organisms in the organic membrane 204 to achieve wastewater treatment, and then the wastewater is discharged through the first straight pipe 4 .

[0031] Wastewater organic membrane bioreactor cleaning:

[0032] The bent rod 301 is pulled outward, and the inner bottom of the bent rod 301 is separated from the circular opening of the outer wall of the shell 1. At the same time, the bent rod 301 moves outward with the ring 302, and the moving ring 302 stretches the spring 303, and then the top cover 6 is lifted upward to separate the frame 7 from the top of the shell 1. The inside of the shell 1 is then cleaned. After completion, the frame 7 is inserted back into the shell 1. At this time, the bottom of the top cover 6 fits with the top of the shell 1, and the bent rod 301 is released. The spring 303 provides a rebound force to make the ring 302 move inward with the bent rod 301, so that the inner side of the outer wall of the bent rod 301 is plugged into the circular opening of the outer wall of the shell 1.

[0033] Example 2:

[0034] See also Figure 1-6 In this embodiment, a wastewater organic membrane bioreactor further includes a glass plate 9, and the outer walls of the multiple glass plates 9 are respectively fixed to the upper left and right sides of the shell 1.

[0035] Working principle:

[0036] The situation inside the housing 1 can be observed at any time through the glass plate 9, and the use situation of the organic film 204 can be checked, so that the organic film 204 can be replaced in time.

[0037] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
