Description

Technical Field

[0001] This invention relates to the field of toilet wastewater treatment technology, and in particular to a toilet wastewater treatment device and method based on microorganisms. Background Technology

[0002] With the rapid development of advanced environmental protection industry, water pollution control and treatment has become one of the core tasks in the field of environmental protection. Among them, the effective treatment of toilet sewage is a key link in improving the living environment and controlling water pollution. At present, microbial environmental toilets have occupied a certain share in the environmental toilet market due to their advantages such as eco-friendliness and relatively low operating costs. They have been widely used, especially in some areas and places with high environmental protection requirements and urgent needs for the renovation of traditional toilets. Many domestic enterprises and research institutions have also been involved in their research and development and production, and market competition is gradually intensifying. The main biochemical reaction of toilet sewage treatment equipment is carried out in the SBR (Sequencing Batch Reactor) activated sludge process reactor. During the operation of the system, the processes of water intake, aeration, static sedimentation, drainage, and idle are all completed in one tank.

[0003] In existing toilet wastewater treatment equipment, wastewater is introduced into the SBR (Sequencing Batch Reactor) activated sludge reactor during operation. The anaerobic bacteria in the activated sludge are accelerated to treat the wastewater by the stirring equipment. However, the reactor is relatively large, and the stirring equipment cannot cover the entire reactor. This results in the activated sludge outside the stirring equipment coverage not being effectively mixed with the wastewater, reducing the wastewater treatment effect. At the same time, during the aeration operation after stirring, the utilization rate of some activated sludge is further reduced because some activated sludge is not mixed with the wastewater to a low degree. Summary of the Invention

[0004] This invention discloses a toilet wastewater treatment device and method based on microorganisms, aiming to solve the technical problem in existing SBR reactors where the stirring equipment cannot cover the entire tank, resulting in uneven mixing of some activated sludge with wastewater, reducing the anaerobic treatment effect, and affecting the utilization rate of this part of the sludge during subsequent aeration.

[0039] A microbial-based toilet wastewater treatment method, using a microbial-based toilet wastewater treatment device as described above, includes the following steps:

[0040] Step 1: Wastewater enters the partition ring frame directly through the inlet pipe. It passes evenly through the various material passage holes on the spiral blade to the partition ring plate. The screw pump lifts the activated sludge located at the bottom of the SBR reactor into the lifting cylinder. It is squeezed out through the overflow hole along the lifting cylinder. The squeezed activated sludge and wastewater are quickly connected. The stirring motor drives the stirring blades on the stirring shaft to stir and mix the two.

The circulation auxiliary mechanism works with the partition mixing mechanism to achieve efficient mixing of sewage and activated sludge.

[0042] Step 3: After the wastewater is added and the mixing is finished, start the aerator.

After sedimentation is complete, the supernatant is discharged through the decanter, and the operation ends.

[0043] As can be seen from the above, the wastewater treatment equipment based on microorganisms provided by the present invention has the following technical effects: after the wastewater enters the SBR reactor, it flows into the partition ring frame through the inlet pipe, passes through the material passage hole of the spiral blade to the partition ring plate, the screw pump lifts the activated sludge at the bottom of the tank to the lifting cylinder, and squeezes it out through the overflow hole to quickly mix with the wastewater. The stirring motor drives the stirring blades on the stirring shaft to stir. The mixed wastewater enters the integration ring frame through the branch pipe, and is then sent to the other end of the tank through the long-distance outlet frame, pushing the activated sludge there to move towards the extraction pipe of the screw pump, thereby achieving the technical effect of fully mixing the wastewater with the activated sludge at the bottom, improving the stirring effect, and maximizing the utilization rate of anaerobic bacteria in the activated sludge.

Detailed Implementation

[0055] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0056] The microbial-based toilet wastewater treatment equipment disclosed in this invention is mainly applied in existing SBR reactors where the mixing equipment cannot cover the entire tank, resulting in uneven mixing of some activated sludge with wastewater, reducing the anaerobic treatment effect, and affecting the utilization rate of this part of the sludge during subsequent aeration.

[0057] Reference Figures 1-10 A microbial-based toilet wastewater treatment device, comprising:

[0058] SBR reactor 1;

[0059] Multiple docking mounting brackets 2 are fixedly connected at equal intervals to the same inner wall of the SBR reactor 1;

[0060] A partition mixing mechanism 3 is provided on each docking mounting frame 2. The partition mixing mechanism 3 includes a partition ring frame 301, and the partition ring frame 301 is fixedly connected to the side wall of the docking mounting frame 2.

[0061] Multiple screw pumps 18 are fixedly connected to the bottom inner wall of the SBR reactor 1 located below each partition ring 301;

[0062] Aerator 9 is fixedly connected to the bottom inner wall of SBR reactor 1;

[0063] The decanter 8 is fixedly connected to the side wall of the SBR reactor 1 away from the partition ring frame 301;

[0064] Frame 5 is fixedly connected to SBR reactor 1, and DO dissolved oxygen meter 4 is fixedly connected to frame 5.

[0065] Frame 2 12 is fixedly connected to the top of SBR reactor 1 away from DO dissolved oxygen meter 4, and MLSS sludge concentration meter 11 is fixedly connected to frame 2 12.

[0066] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 In a preferred embodiment, the isolation mixing mechanism 3 further includes:

[0067] The partition ring plate 311 is fixedly connected to the inner side wall of the partition ring frame 301 near the bottom end, and a fitting hole is opened at the center point of the partition ring plate 311.

[0068] The lifting cylinder 312 is fixedly connected to the inside of the fitting hole. The bottom of the lifting cylinder 312 is fixedly connected to the connecting pipe 23, which is connected to the output end of the screw pump 18.

[0070] In a specific application scenario, after the wastewater is introduced into the SBR reactor 1, it is first subjected to agitation. The wastewater enters the partition ring frame 301 directly through the inlet pipe 22. It passes evenly through the various material passage holes 309 on the spiral blade 303 onto the partition ring plate 311. The screw pump 18 lifts the activated sludge located at the bottom of the SBR reactor 1 into the lifting cylinder 312. It is squeezed out through the overflow hole 313 along the lifting cylinder 312. The squeezed activated sludge and wastewater are quickly connected. The stirring motor 302 drives the stirring blades 310 on the stirring shaft 315 to stir and mix the two. The mixed wastewater enters the integration ring frame 306 through the branch pipe 305. Then, it is transferred to the other end of the SBR reactor 1 through the long-distance outlet frame 6. The outlet wastewater pushes the activated sludge in this part, gradually pushing it to the extraction pipe 15 of the screw pump 18, thereby achieving full mixing of wastewater and activated sludge at the bottom, improving the stirring effect, and maximizing the utilization rate of anaerobic bacteria in the activated sludge.

[0071] Specifically, during the wastewater treatment interval of the SBR reactor 1, the pipe valve 16 is closed, and clean water is introduced into the screw pump 18 through the clean water addition pipe 19. The clean water is then pumped into the partition ring frame 301 by the screw pump 18. The flow of clean water cleans the internal structure of the partition ring frame 301, preventing wastewater stagnation that could cause corrosion damage to the various structures within the partition ring frame 301.

The drive motor 1008 drives each elastic connecting rod 1013 to unfold, and then the striking head 1009 strikes the long-distance discharge frame 6 to make it vibrate, thereby preventing the mixture of sewage and activated sludge from remaining in the long-distance discharge frame 6 and causing blockage.

[0084] It should be noted that during the movement of the fitting frame 1006, the pull spring rod 1010 is stretched or contracted accordingly, thereby ensuring that the fitting frame 1006 and the long-distance guide frame 6 are always in a fitted state.

[0091] Specifically, during the operation of the isolation mixing mechanism 3, the rotating motor 705 is started, and the rotating motor 705 drives each flipping blade 706 to rotate, thereby pushing the activated sludge away from the screw pump 18 to the screw pump 18. This, together with the isolation mixing mechanism 3, achieves efficient mixing between sewage and activated sludge.

The squeezed activated sludge and wastewater are quickly connected. The stirring motor 302 drives the stirring blades 310 on the stirring shaft 315 to stir and mix the two. The mixed wastewater enters the integrated ring frame 306 through the branch pipe 305, and then is transferred to the other end of the SBR reactor 1 through the long-distance outlet frame 6.

[0097] Step 2: During the operation of the isolation mixing mechanism 3, the rotating motor 705 is started. The rotating motor 705 drives each flipping blade 706 to rotate, thereby pushing the activated sludge away from the screw pump 18 to the screw pump 18.

After aeration, aerator 9 is turned off, and the wastewater in SBR reactor 1 is in the sedimentation stage. After sedimentation is completed, the supernatant is discharged through decanter 8, and the operation ends.

7. A method for treating toilet wastewater based on microorganisms, using a toilet wastewater treatment device based on microorganisms as described in claim 2, characterized in that, Includes the following steps: Step 1: Wastewater enters the partition ring frame (301) directly through the inlet pipe (22).
