Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sludge return device for a water circulation ecological toilet. Background Art

[0002] Microbial degradation ecological toilets use biological methods and microbial agents to decompose organic matter in feces into carbon dioxide and water, achieving sewage reuse or standard discharge and avoiding sewage pollution of the environment.

[0003] In the treatment system, the main reaction unit is the treatment tank. The treatment tank is generally divided into multiple reaction pools. According to the A2O treatment process, the reaction pools are the regulating pool, the anoxic pool, the anaerobic pool, and the aerobic pool. Microbial strains in sewage will selectively react and survive under suitable conditions, and reproduce by forming biofilms with the help of the carriers. Through anaerobic reactions, aerobic reactions, nitrification reactions and other processes, most of the organic matter is decomposed into carbon dioxide and water. The whole process requires the dynamic flow and circulation of sewage to better fully contact the organic matter in the sewage and the strains, so as to achieve the goal of full degradation. In the actual use of the bathroom, most of them are used during the day and not at night, which makes it impossible for sewage to flow naturally in the reaction tank. Utility Model Content

DETAILED DESCRIPTION

[0018] The present invention is not limited by the following embodiments, and specific implementation methods can be determined according to the technical solution of the present invention and actual conditions.

[0019] The present invention is further described below in conjunction with the embodiments and drawings:

[0020] like Figure 1-5 As shown, a sludge return device for a water circulation ecological toilet comprises an air hose 1, an air regulating valve 2, a stainless steel thread 3, a vertical thin straight tube 4, a horizontal thin straight tube 5, a first vertical thick straight tube 6, a reducing tee 7, a second vertical thick straight tube 8, a horizontal thick straight tube 9 and a pipe cap 10; the air regulating valve 2 is fixedly installed on the outside of the air hose 1, the stainless steel thread 3 is fixedly connected to the upper end of the air hose 1, the end of the stainless steel thread 3 away from the air hose 1 is connected to the vertical thin straight tube 4, the lower end of the vertical thin straight tube 4 is connected to the horizontal thin straight tube 5 which is perpendicular to the vertical thin straight tube 4, and the first vertical thick straight tube 4 is arranged in parallel behind the vertical thin straight tube 4. 6, the outer side of the bottom of the first vertical thick straight tube 6 is connected to the horizontal thin straight tube 5 through a reducing tee 7, a second vertical thick straight tube 8 is arranged in parallel on the left side of the first vertical thick straight tube 6, and the upper end of the second vertical thick straight tube 8 is connected to the upper end of the first vertical thick straight tube 6 through a horizontal thick straight tube 9; a pipe cap 10 is connected to the bottom end of the first vertical thick straight tube 6, and the pipe cap 10 is provided with a plurality of first connecting holes that pass through from top to bottom, and a plurality of second connecting holes that pass through from inside to outside are arranged on the outer side of the bottom of the first vertical thick straight tube 6 above the pipe cap 10, and the second connecting holes are located on the outer side of the first vertical thick straight tube 6 below the horizontal thin straight tube 5.

[0021] When working, the device will be placed in the reaction tank at the rear end of the treatment tank of the toilet microbial degradation system. Specifically, the lower end of the air hose 1 is connected to the external air pump, and the gas flow is controlled by adjusting the air regulating valve 2. After the air enters through the air hose 1, it passes through the vertical thin straight tube 4 and the horizontal thin straight tube 5 in turn. At the reducing tee 7, the pressurized gas will be divided into two air flows, one of which flows downward through the first connecting hole at the bottom of the pipe cap 10 and the second connecting hole on the first vertical thick straight tube 6 to be discharged to the bottom of the sewage tank. At the same time, due to the impact force, the pressurized gas stirs the sludge and sediment at the bottom of the tank, causing the flow and tumbling of the bottom water body, while the other gas flows upward through the first vertical thick straight tube 6 and flows out from the second vertical thick straight tube 8. The upward airflow drives the gas in the pipe to flow upward, and the sludge and sediment at the bottom of the tank will enter from the rear end reaction tank of the treatment tank along with the flow of the water body in the pipe, and enter the predetermined reaction tank at the front end of the treatment tank, thereby playing a role in reflux of the sludge.

[0022] Among them, both ends of the air regulating valve 2 are socket-type, which can be quickly connected to the air hose 1. The air regulating valve 2 can adjust the gas flow rate through its knob, thereby controlling the exhaust volume of the device and the boiling degree of sewage; the vertical thin straight pipe 4 can match the length according to the depth of the sewage pool; the first vertical thick straight pipe 6, the horizontal thick straight pipe 9 and the second vertical thick straight pipe 8 are combined in an n shape, and the first vertical thick straight pipe 6 below the reducing tee 7 and the horizontal thin straight pipe 5 and the part containing the reducing tee 7 are prevented from being in the front end reaction pool of the treatment tank; the horizontal thick straight pipe 9 is installed on the reaction pool partition of the treatment tank box, and the lengths of the first vertical thick straight pipe 6 and the second vertical thick straight pipe 8 are matched according to the depth of the reaction pool.

[0023] In summary, the utility model has a simple structure and is easy to use. It is composed of existing common accessories and materials and has a low production cost. The sludge in the rear end reaction tank of the reaction tank in the bathroom sewage treatment system is carried and transported to the reaction tank at the front end of the reaction tank, thereby realizing dynamic reflux and circulation of the sludge in the reaction tank, so that the organic matter in the sludge can fully contact and react with the microbial strains, thereby achieving the complete degradation and purification of the sewage, improving the effect of sewage purification, and realizing the purpose of sludge reflux.

[0025] Among them, the stainless steel butt wire 3 is welded and installed on the upper end of the partition of the processing tank; one end of the air pipe quick-connect elbow 11 is a socket type, which can be quickly connected to the air hose 1.

[0026] like Figure 1-5 As shown, the first elbow 13 is also included, and the quick connector 12 and the vertical thin straight tube 4 are connected together through the first elbow 13. Thus, the connection between the quick connector 12 and the vertical thin straight tube 4 is convenient.

[0027] like Figure 1-5 As shown, the second elbow 14 and the third elbow 15 are also included. The upper end of the first vertical thick straight pipe 6 is connected to the right end of the horizontal thick straight pipe 9 through the second elbow 14, and the left end of the horizontal thick straight pipe 9 is connected to the upper end of the second vertical thick straight pipe 8 through the third elbow 15. Thus, the connection between the first vertical thick straight pipe 6, the horizontal thick straight pipe 9 and the second vertical thick straight pipe 8 is facilitated.

[0028] like Figure 1-5 As shown, a fourth elbow 16 is also included, and the vertical thin straight tube 4 and the horizontal thin straight tube 5 are connected together through the fourth elbow 16.
