Technical Field

[0001] The utility model relates to the technical field of domestic sewage reuse treatment, in particular to a domestic sewage reuse treatment device. Background Art

[0002] In the daily treatment of domestic sewage, domestic sewage reuse treatment refers to the process of properly treating domestic sewage to meet certain water quality standards and then reusing it for specific purposes. At the same time, this treatment operation not only helps to recycle water resources and reduce environmental pollution, but also solves the problem of water shortage to a certain extent.

[0003] In the existing domestic sewage reuse treatment, when treating domestic sewage, the domestic sewage discharged from various pipelines is generally transported together to the treatment device for centralized treatment. However, considering that in some cases, relatively clean domestic sewage (such as washbasin drainage, shower drainage, circulating cooling water, etc.) will be discharged from the pipeline, if a multi-stage treatment process (such as anaerobic process, aerobic process, sedimentation process, etc.) is used to treat these relatively clean domestic sewage, it often leads to waste of resources and excessively prolongs the treatment time, and is not conducive to the rapid reuse of these sewage. Therefore, a domestic sewage reuse treatment device is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a domestic sewage reuse treatment device to solve the problem of waste of resources in the existing domestic sewage reuse treatment proposed in the above background technology.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] A domestic sewage reuse treatment device includes a treatment chassis 1, a screening tank 2 is provided on one side of the interior of the treatment chassis 1, a multi-stage treatment inner chamber 3 is provided in the middle position of the interior of the treatment chassis 1, and side flow channels 4 are respectively provided at the front and rear ends of the multi-stage treatment inner chamber 3. The front and rear ends of the upper left side of the treatment chassis 1 are respectively connected to a first sewage inlet 5 and a second sewage inlet 6, and the front and rear ends of the treatment chassis 1 are respectively fixedly installed with water quality sensors 7. The screening tank 2 and the side flow channel 4 are connected by a side water outlet 8, and the side water outlet 8 and the screening tank 2 are integrally formed. A disinfection tank 13 is provided on the other side of the interior of the treatment chassis 1, and the disinfection tank 13 and the side flow channel 4 are connected by a side confluence 17, and the side confluence 17 and the disinfection tank 13 are integrally formed.

[0020] like Figure 1 and Figure 2As shown, the right side of the treatment chassis 1 is connected with a water outlet short pipe 15, and the water outlet short pipe 15 is connected to a diversion tee 16 at a side away from the treatment chassis 1. The front and rear ends of the diversion tee 16 and the side away from the water outlet short pipe 15 are respectively connected with diversion pipe openings 18. When the treated domestic sewage is discharged outward through the inside of the water outlet short pipe 15, the diversion tee 16 can be connected to the three discharge pipes at the same time, and the device can be used to guide the domestic sewage to various places where water is needed for reuse; a multi-valve controller 12 is provided between the first sewage inlet 5 and the second sewage inlet 6, and the multi-valve controller 12 is fixedly installed at the left side of the treatment chassis 1, and the screening tank 2 is connected to a central water outlet 9 at one side near the middle of the treatment chassis 1. The center The water outlet 9 extends to the interior of the multi-stage treatment inner chamber 3. When the central water outlet 9 is opened, the dirtier domestic sewage will enter the interior of the multi-stage treatment inner chamber 3 through the interior of the central water outlet 9 to carry out the next level of treatment operation, and be diverted and used at the same time as the first sewage inlet 5 and the second sewage inlet 6, which can reduce the load generated by the single inlet water intake; the multi-stage treatment inner chamber 3 and the disinfection tank 13 are connected through the central confluence 14, and the detection probe end of the water quality sensor 7 extends to the interior of the screening tank 2. The front and rear sets of side flow channels 4 are respectively integrally formed between the treatment chassis 1. After the domestic sewage is preliminarily filtered and flows into the lower position inside the screening tank 2, the device will use a set of water quality sensors 7 to perform online detection of the water quality of the domestic sewage.

[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, a sieve plate 10 is mounted on the inner side of the screening pool 2. The surface of the sieve plate 10 is a porous structure. Two hangers 11 are provided on the top of the sieve plate 10 in a front-to-back symmetrical structure. The hanger 11 has an "L"-shaped structure. The horizontal end of the hanger 11 is overlapped with the edge of the screening pool 2. After the sieve plate 10 has been used for a period of time and the entire device is opened, the sieve plate 10 can be pulled out by pulling it upward through a group of hangers 11, so that the dirt filtered out from the surface of the sieve plate 10 can be easily cleaned later.

[0022] Working process: The electric energy required for the startup and operation of the device in the present invention comes from the power supply. The solenoid valves controlling the flow of a group of side water outlets 8 and the central water outlet 9 are respectively controlled by the multi-valve controller 12, and the multi-valve controller 12 of model JMA501 and the water quality sensor 7 of model JZ-PH are respectively electrically connected to the sewage treatment main control system. When it is necessary to use the domestic sewage reuse treatment device, before the device is used, the domestic sewage discharge pipeline can be connected to the external device through the first sewage inlet 5 and the second sewage inlet 6 respectively. First, the domestic sewage flows into the interior of the screening tank 2 through the first sewage inlet 5 and the second sewage inlet 6 in turn, and after the residue is filtered through the sieve plate 10 provided therein, the entire device will enter the water quality online monitoring through a group of water quality sensors 7 extending to the lower position inside the screening tank 2. Then, if it is detected that the water quality is too dirty, , the domestic sewage will be opened through the central water outlet 9 and gradually sent into the interior of the multi-stage treatment inner chamber 3 for multi-stage deep treatment (such as anaerobic treatment, acid-base adjustment treatment, sedimentation treatment, etc.). After the cleaned domestic sewage enters the interior of the disinfection tank 13 through the central confluence 14 for disinfection treatment, it will flow out through the interior of the water outlet short pipe 15, the diversion tee 16 and the diversion pipe mouth 18 in sequence for reuse. At the same time, if the water quality is detected to be relatively clean, the domestic sewage will flow into the interior of the side flow channel 4 through a group of side water outlets 8 in sequence after preliminary filtration, and enter the interior of the disinfection tank 13 through a group of side confluences 17 for disinfection treatment. After the domestic sewage has been simply filtered, it will also flow out through the interior of the water outlet short pipe 15, the diversion tee 16 and the diversion pipe mouth 18, so as to facilitate its rapid reuse.
