[0025] The present utility model provides a sewage treatment device and a sewage treatment system. Figure 1 This is a specific embodiment of a sewage treatment device provided by the present utility model.
[0026] As Figure 1 shown, the embodiment of the present utility model provides a sewage treatment device 100, including a housing 1, a water inlet part 2, and a pH adjustment component 3. A water storage cavity is provided in the housing 1. Both the water inlet part 2 and the pH adjustment component 3 are provided at the top of the housing 1. One end of the water inlet part 2 forms a sewage inlet 21, and an exhaust gas treatment cavity is provided in the water inlet part 2. The pH adjustment component 3 has a sewage treatment cavity for adjusting the pH of sewage. The sewage inlet 21 is communicated with the sewage treatment cavity through the exhaust gas treatment cavity. The sewage treatment cavity is communicated with the water storage cavity. A water outlet 11 is opened on one side of the housing 1, and the water outlet 11 is communicated with the water storage cavity.
[0027] In the present utility model, a water storage cavity is provided inside the housing 1. The water inlet part 2 and the pH adjustment component 3 are both arranged at the top of the housing 1. One end of the water inlet part 2 forms a sewage inlet 21, and an exhaust gas treatment cavity is provided inside the water inlet part 2. The pH adjustment component 3 has a sewage treatment cavity for adjusting the pH of sewage. The sewage inlet 21 is communicated with the sewage treatment cavity through the exhaust gas treatment cavity. The sewage treatment cavity is communicated with the water storage cavity. An outlet 11 is formed on one side of the housing 1, and the outlet 11 is communicated with the water storage cavity. Sewage flows into the water inlet part 2 from the sewage inlet 21, harmful exhaust gas is removed in the exhaust gas treatment cavity, then it enters the sewage treatment cavity, after acid-base neutralization is completed in the sewage treatment cavity, the sewage flows into the water storage cavity for storage, and finally flows out from the outlet 11 to the next process of sewage treatment. In this application, the sewage first completes the removal of harmful exhaust gas in the exhaust gas treatment cavity, then flows into the sewage treatment cavity, and after completing the acid-base neutralization treatment, it enters the water storage cavity. Since both the exhaust gas treatment cavity and the sewage treatment cavity are above the water storage cavity, the entire sewage treatment process is only driven by the gravity of the sewage. Compared with the prior art where sewage is first output to a water storage tank, and then the sewage in the tank is pumped out by a screw pump, and acid-base neutralization is completed in the pumping pipeline and then returned to the tank, this application does not require the setting of pumping equipment and pipelines, and integrates the exhaust gas treatment component and the water inlet component, with lower cost and smaller occupied space.
[0028] It should be noted that the specific structure of the pH adjustment component 3 is not limited, as long as it can ensure that the pH adjustment component 3 can adjust the pH of sewage. For example, in some embodiments, as Figure 1 shown, the pH adjustment component 3 includes a neutralization reaction part 31 and an adjustment part 32 for controlling the output of acid-base neutralization liquid. The neutralization reaction part 31 has the sewage treatment cavity inside, and the adjustment part 32 is communicated with the sewage treatment cavity. With such a setting, the adjustment part 32 outputs the acid-base neutralization liquid to the sewage treatment cavity inside the neutralization reaction part 31, mixes with the sewage, and conducts a neutralization reaction, thereby adjusting the pH of the sewage.
[0029] Specifically, when the sewage is acidic, the acid-base neutralization liquid is alkaline water, and when the sewage is alkaline, the acid-base neutralization liquid is acidic water.
[0030] Preferably, in some embodiments, as Figure 1As shown, a pH detection unit 5 is provided on one side of the housing 1. The pH detection unit 5 is communicated with the water outlet 11. Both the pH detection unit 5 and the adjustment unit 32 are electrically connected to the controller. The pH detection unit 5 can send the detected sewage pH value to the controller to ensure that the output sewage is completed with acid-base neutralization treatment. For example, if the sewage is acidic and the acid-base neutralizing liquid is alkaline water, when the pH detection unit 5 detects that the output sewage is still acidic, it means that the amount of alkaline water controlled by the adjustment unit 32 is insufficient, and the controller controls the adjustment unit 32 to increase the output amount of alkaline water; when the pH detection unit 5 detects that the output sewage is alkaline, it means that the amount of alkaline water controlled by the adjustment unit 32 is excessive, and the controller controls the adjustment unit 32 to reduce the output amount of alkaline water. Through such dynamic adjustment, it is finally ensured that the output sewage is neutral and the acid-base neutralization treatment is completed.
[0031] There is no limitation on the way the waste gas treatment chamber removes harmful waste gas. In some embodiments, such as Figure 1 As shown, the waste gas treatment chamber is filled with a waste gas adsorption part 22. With such a setting, the sewage first flows into the waste gas treatment chamber from the sewage inlet 21. After the harmful waste gas is adsorbed and removed by the waste gas adsorption part 22, it then flows into the sewage treatment chamber for acid-base neutralization treatment. Specifically, the waste gas adsorption part 22 can be honeycomb ball packing, or other components well-known to those skilled in the art that can remove waste gas.
[0032] Furthermore, if the sewage directly flows into the waste gas treatment chamber and then flows out under the action of gravity, the waste gas adsorption part 22 can only adsorb a small amount of waste gas on the surface. In order to improve the effect of removing waste gas, in some embodiments, such as Figure 1 As shown, the sewage inlet 21 is connected with a spraying part 23. The spraying part 23 is arranged in the waste gas treatment chamber and is located above the waste gas adsorption part 22. With such a setting, the sewage is first turned into mist-like small water droplets by the spraying part 23, greatly increasing the contact area between the sewage and the waste gas adsorption part 22, thereby improving the effect of the waste gas adsorption part 22 in removing waste gas.
[0033] Since the adsorption capacity of the waste gas adsorption part 22 will gradually weaken as the amount of adsorbed waste gas gradually increases, in order to ensure that the waste gas adsorption part 22 always has a strong adsorption capacity, in some embodiments, such as Figure 1As shown, the water inlet part 2 is provided with an air inlet 24 and an air outlet 25. The waste gas adsorption part 22 is located between the air inlet 24 and the air outlet 25. The air inlet 24 and the air outlet 25 are communicated through the waste gas treatment cavity. Specifically, the air inlet 24 is below the waste gas adsorption part 22, and the air outlet 25 is above the waste gas adsorption part 22. With such a setting, since the density of air is small, when air enters from the air inlet 24, it will rise to the waste gas adsorption part 22, carry away the waste gas, and finally the air carrying the waste gas is discharged from the air outlet 25.
[0034] Furthermore, in order to prevent some of the air carrying waste gas from flowing through the sewage treatment cavity and the water storage cavity and being discharged from the water outlet 11, in some embodiments, as Figure 1 shown, a partition part 12 is provided in the water storage cavity. The partition part 12 extends from top to bottom, and the lower end of the partition part 12 is lower than the water outlet 11. The partition part 12 divides the space above the liquid level in the water storage cavity into two chambers. The communication port between the sewage treatment cavity and the water storage cavity is located in one of the chambers, and the water outlet 11 is located in the other chamber. With such a setting, the sewage treatment cavity is separated from the water outlet 11 by the partition part 12 and the liquid in the storage cavity, avoiding the air carrying waste gas from being discharged from the water outlet 11 and affecting the subsequent sewage treatment process.
[0035] When the sewage treatment device 100 is used for a long time, it may malfunction. In order to facilitate maintenance personnel to carry out maintenance, in some embodiments, as Figure 1 shown, a drainage part 13 is provided at the bottom of the housing 1. The drainage part 13 is communicated with the water storage cavity, and a drainage valve 131 is provided on the drainage part 13. When maintenance personnel carry out maintenance, they can open the valve of the drainage valve 131 to drain all the liquid in the water storage cavity to facilitate subsequent maintenance work.
[0036] In order to monitor the liquid level in the water storage cavity in real time and avoid the liquid flowing back into the sewage treatment cavity, in some embodiments, as Figure 1 shown, a liquid level detection part 4 for detecting the water level in the water storage cavity is provided on the housing 1. The liquid level detection part 4 is communicated with the water storage cavity. When the staff monitors that the liquid level detected by the liquid level detection part 4 is too high, the input of sewage and acid-base neutralizing liquid is correspondingly reduced to avoid the liquid flowing back into the sewage treatment cavity.
[0037] In addition, the present utility model further provides a sewage treatment system, including the sewage treatment device 100. The sewage treatment device 100 includes a housing 1, a water inlet part 2, and a pH adjustment component 3. A water storage cavity is provided inside the housing 1. Both the water inlet part 2 and the pH adjustment component 3 are arranged at the top of the housing 1. One end of the water inlet part 2 forms a sewage inlet 21, and an exhaust gas treatment cavity is provided inside the water inlet part 2. The pH adjustment component 3 has a sewage treatment cavity for adjusting the pH of sewage. The sewage inlet 21 is communicated with the sewage treatment cavity through the exhaust gas treatment cavity. The sewage treatment cavity is communicated with the water storage cavity. An outlet 11 is provided on one side of the housing 1, and the outlet 11 is communicated with the water storage cavity.
[0038] The foregoing are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
