Description

Technical Field

[0001] The utility model relates to wastewater treatment, in particular to wastewater treatment testing equipment. Background Art

[0002] Wastewater is typically treated using a combination of adsorbents (such as activated carbon) and various corresponding reagents, using methods such as physical adsorption and chemical reactions. Before large-scale wastewater treatment begins, a portion of the wastewater is typically treated using test equipment. Through debugging, the types and ratios of adsorbents and reagents are determined. Existing test equipment typically places the wastewater in a barrel, where a stirring mechanism agitates the wastewater, adsorbent, and reagents. After a certain reaction time, the wastewater is sampled and analyzed. Existing test equipment typically uses a straw inserted into the barrel and a pump to extract the wastewater. However, this method has drawbacks: It is cumbersome to operate, and during the insertion of the straw, suspended impurities on the wastewater surface can easily enter the straw, causing blockage and affecting the analysis of the wastewater.

[0035] See also Figure 1 、 Figure 2 and Figure 3 A wastewater treatment test equipment includes an equipment frame 1, a barrel 2, a circulation pipeline 3, a pump 4, a stirring mechanism 5, a sampling tube 6, a first valve 7 and a second valve 8.

[0036] The equipment rack 1 can be formed by welding steel bars and provided with a vacant first area 1a.

[0037] The barrel 2 is installed in the first area 1a of the equipment rack 1, that is, the bottom of the barrel 2 is vacant, which is convenient for connecting the subsequent circulation pipeline 3. Accordingly, the bottom of the barrel 2 is provided with a water outlet and a sewage outlet.

[0038] One end of the circulation pipe 3 is connected to the water outlet of the barrel 2, and the other end extends from the top opening of the barrel 2 into the barrel 2. A filter membrane is also provided in the middle part of the circulation pipe 3. More specifically, the circulation pipe 3 may include a first connecting pipe 3a, a second connecting pipe 3b and a third connecting pipe 3c; the first connecting pipe 3a is located at the bottom, and one end is connected to the water outlet of the barrel 2; the second connecting pipe 3b is vertical, and the lower end is connected to the other end of the first connecting pipe 3a; one end of the third connecting pipe 3c is connected to the upper end of the second connecting pipe 3b, and the other end extends and enters the barrel 2; the filter membrane is provided in the second connecting pipe 3b

[0039] For the barrel 2, the water outlet and the sewage outlet can be set separately. Accordingly, a valve for controlling opening / closing needs to be provided on the sewage outlet.

[0040] In some embodiments, the water outlet and sewage outlet can be the same outlet. Accordingly, the end of the circulation line 3 connected to the water outlet (i.e., the end opposite the first connecting pipe 3a) is provided with a three-way joint 3a1. The three-way joint 3a1 is in an inverted T-shape, with the upward joint connected to the water outlet, the joint on one side connected to the first connecting pipe 3a, and the joint on the other side serving as the sewage outlet. A fourth valve 3a2 and a fifth valve 3a3 are respectively provided on the joints on either side of the three-way joint 3a1. Specifically, if the fourth valve 3a2 is closed and the fifth valve 3a3 is opened, the outlet functions as a sewage outlet; if the fifth valve 3a3 is closed and the fourth valve 3a2 is opened, the outlet functions as a water outlet.

[0041] In this way, compared with the separate arrangement of the water outlet and the sewage outlet, the structure is simpler, the space occupied is smaller, and the installation is more convenient.

[0042] Pump 4 is connected to circulation line 3, allowing wastewater in barrel 2 to flow from the outlet through circulation line 3 back into barrel 2. When describing how sampling tube 6, second valve 8, and other components are connected to circulation line 3, the preceding and following positions are described with reference to this wastewater flow direction. More specifically, pump 4 is mounted on equipment rack 1 near first area 1a. First connecting pipe 3a is divided into two sections: one connecting the outlet to pump 4's inlet, and the other connecting second connecting pipe 3b to pump 4's outlet.

[0043] The stirring mechanism 5 acts on the barrel 2. A stirring rod can be used as the stirring mechanism 5 to stir the barrel 2 so that the wastewater, adsorbent, and reagent in the barrel 2 are evenly mixed.

[0044] In some embodiments, the stirring mechanism 5 includes an aeration pipe 5a, an air compressor 5b, and a fourth connecting pipe 5c. The aeration pipe 5a is located within the barrel 2, more specifically, at the bottom of the barrel 2. The air compressor 5b is located outside the equipment rack 1 or can be mounted on the equipment rack 1. The fourth connecting pipe 5c connects the aeration pipe 5a and the air compressor 5b. More specifically, the fourth connecting pipe 5c includes a rigid pipe fixedly connected to the aeration pipe 5a and a flexible pipe connecting the rigid pipe and the air compressor 5b.

[0045] In this way, compared with using a stirring rod, the aeration pipe 5a can stir the wastewater and more easily make the impurities in the wastewater float upward.

[0046] Furthermore, the aeration pipe 5a may be in a Japanese-style shape, and there are two groups of fourth connecting pipes 5c. A tee is provided between the two hoses, and the other connector of the tee is connected to the air compressor 5b.

[0047] The sampling tube 6 is connected to the position after the filter membrane in the circulation pipeline 3. After that means: under the action of the pump 4, the wastewater first passes through the filter membrane and then passes through the connection position of the sampling tube 6 in the circulation pipeline 3.

[0048] The first valve 7 is arranged between the circulation pipeline 3 and the sampling tube 6. That is, when the first valve 7 is closed, the wastewater does not pass through the sampling tube 6 and returns to the barrel 2 from the circulation pipeline 3; when the first valve 7 is opened, the wastewater flows out of the sampling tube 6 and the sampling operation can be carried out.

[0049] The second valve 8 is arranged after the sampling tube in the circulation line 3. When the first valve 7 is opened, the flow rate flowing out of the sampling tube 6 can be adjusted by adjusting the second valve 8.

[0050] In some embodiments, the circulation line 3 includes multiple second connecting pipes 3b. Multiple filter membranes are provided, sequentially disposed in the multiple second connecting pipes 3b. Multiple first valves 7 are provided, sequentially disposed between the multiple second connecting pipes 3b and the sampling pipe 6. More specifically, a connecting pipe is provided between the sampling pipe and each first connecting pipe, and the first valve 7 is disposed on this pipe. Multiple second valves 8 are provided, sequentially disposed in the multiple second connecting pipes 3b.

[0051] Furthermore, the wastewater treatment test equipment further comprises a plurality of third valves 9. The plurality of third valves 9 are sequentially arranged at positions of the plurality of second connecting pipes 3b before the filter membranes.

[0052] In this way, by closing the second valve 8 and the third valve 9 on one of the second connecting pipes 3b, the waste water can not pass through the second connecting pipe.

[0053] In some embodiments, the wastewater treatment test equipment further comprises a flow meter 10. The flow meter 10 is disposed in the circulation pipeline 3 after the pump 4. The flow rate can be observed more intuitively.
