Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater purification method. Background Technology

[0002] Currently, wastewater purification is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse.

[0003] In the process of wastewater purification, the filtration and removal of impurities is a very basic purification step, which directly determines the subsequent purification effect and efficiency. In the existing technology, when filtering out large impurities, most of them are filtered by screens. However, large impurities are very easy to clog the upper part of the screen, which affects the continuous filtration effect of the screen and requires regular manual cleaning, which is time-consuming and labor-intensive. Summary of the Invention

[0045] S13. After removing large solid impurities from the wastewater first, small solid impurities are removed from the wastewater using a filtration device.

[0046] S14. Discharge the wastewater from the filtration device to complete the filtration process.

[0047] The adsorbent in S4 is activated carbon.

[0048] In step S5, ozone gas is used to disinfect wastewater.

[0049] The pH adjuster in S6 is one of lime, limestone, dolomite, sodium hydroxide, and sodium carbonate.

[0050] like Figure 4 and Figure 7-9 As shown:

[0051] The filtration device includes a processing box 101 and a fixed rod 401. A baffle 104 is slidably connected to the processing box 101. The processing box 101 is provided with multiple filter holes 103, all of which are located on the right side of the baffle 104. The processing box 101 is tilted with the left side higher than the right side. A slider 402 is slidably connected to the fixed rod 401. A rotating part 501 is rotatably connected to the slider 402. A torsion spring is fixed between the rotating part 501 and the slider 402. A retrieval arc plate 502 is rotatably connected to the rotating part 501. A transmission rail 403 is connected to the processing box 101. The transmission rail 403 can contact the rotating part 501. A first electric push rod that can push the baffle 104 to slide is fixed to the processing box 101. A first compression spring is fixed between the fixed rod 401 and the slider 402. A second motor that can drive the retrieval arc plate 502 to rotate is fixed to the rotating part 501.

[0052] Wastewater is added through the left side of the treatment tank 101, allowing it to flow naturally along the tank to the right side. Before pouring in the wastewater, the baffle 104 can be adjusted to slide on the treatment tank 101, thereby adjusting the gap between the baffle 104 and the treatment tank 101. This prevents large solid impurities in the wastewater from entering the right side of the treatment tank 101 through the gap between the treatment tank 101 and the baffle 104, thus achieving efficient filtration of large solid impurities without the need for a filter screen. This eliminates the need for frequent filter screen cleaning, ensuring long-term filtration efficiency and providing convenience for operators.

[0053] Water passing through the gap between the baffle 104 and the treatment box 101 will enter the right side of the baffle 104 and then be filtered through multiple filter holes 103 to remove small impurities in the wastewater and achieve a comprehensive filtration effect.

[0054] During the filtration operation, the retrieval arc plate 502 rotates continuously on the rotating part 501, causing it to gradually lift up large pieces of impurities pressed against the left side of the baffle 104. As the retrieval arc plate 502 continues to rotate on the rotating part 501, it gradually presses against the baffle 104. This further rotation causes the baffle 104 to gradually push the slider 402 against the fixed rod 401, overcoming the spring force of the first compression spring. Consequently, the slider 402 gradually slides from right to left on the fixed rod 401. During this sliding process, the rotating part 501 gradually... When in contact with the transmission rail 403, the transmission rail 403 gradually rotates the rotating part 501 on the slider 402 due to its shape, overcoming the torsional force of the torsion spring. This causes the retrieval arc plate 502 to gradually rotate to a front-high, rear-low posture, allowing large impurities retrieved from the retrieval arc plate 502 to automatically slide out of the device along the inclined retrieval arc plate 502. This automatically and efficiently removes large impurities accumulated in the device, maintaining a long-term high-efficiency filtration effect for large solid impurities. At the same time, it prevents large impurities from completely clogging the gap between the treatment box 101 and the baffle 104, thus affecting the normal flow of water.

[0055] like Figure 4 , Figure 7 and Figure 8 As shown:

[0056] The device also includes a slide rail 102 fixedly connected to the processing box 101, a transmission rail 403 slidably connected to the slide rail 102, and a second compression spring fixedly connected between the slide rail 102 and the transmission rail 403.

[0057] The slidable arrangement of the transmission rail 403 allows the rotating part 501 to be tilted by the transmission rail 403, thus enabling the dumping of large impurities from the retrieval arc plate 502. After dumping is completed, the retrieval arc plate 502 can be operated to continue rotating. At this time, the rotating part 501 will gradually move to the right to a position offset from the transmission rail 403, allowing the rotating part 501 to rotate and reset on the slider 402. Subsequently, as the retrieval arc plate 502 continues to rotate, it gradually separates from the baffle 104, allowing the slider 402 to slide and reset on the fixed rod 401. The rotating part 501 can then quickly and smoothly reset from the underside of the transmission rail 403 by sliding the transmission rail 403 upwards, thus facilitating the next dumping operation.

[0058] like Figure 5 As shown:

[0059] The device also includes a receiving plate 105 slidably connected to the processing box 101, and a second electric push rod that can push the receiving plate 105 to slide is fixed on the processing box 101.

[0060] When dumping large impurities from the salvage arc plate 502, the operating receiving plate 105 can slide on the processing box 101, thereby moving the receiving plate 105 directly below the salvage arc plate 502, thus guiding the falling large impurities and facilitating their normal discharge.

[0061] like Figure 5-6 As shown:

[0062] The device further includes a slide plate 201 slidably connected to a processing box 101, an agitator 202 rotatably connected to the slide plate 201, an extension 203 slidably connected to the agitator 202, a third compression spring fixed between the agitator 202 and the extension 203, a push rod 301 slidably connected to the slide plate 201, a contact head 302 fixedly connected to the push rod 301, a push plate 204 fixedly connected to the extension 203, the contact head 302 being able to contact the push plate 204, a first motor fixedly connected to the processing box 101, a first lead screw fixedly connected to the output shaft of the first motor, the first lead screw being threadedly connected to the slide plate 201, a third motor fixedly connected to the slide plate 201 capable of driving the extension 203 to rotate, and a third electric push rod fixedly connected to the slide plate 201 capable of driving the push rod 301 to slide.

[0063] During the filtration process, the operable stirring part 202 rotates continuously on the slide plate 201, which in turn causes the stirring part 202 to drive the extension part 203 to rotate continuously, thereby continuously stirring the large impurities on the left side of the baffle 104, so that the large impurities will not be placed in a relatively static position on the treatment box 101 for a long time, thus further ensuring that the large impurities will not affect the normal flow of the subsequent sewage.

[0064] During the agitation process using the agitator 202, the operable push rod 301 slides back and forth on the slide plate 201, thereby pushing the push plate 204 through the contact head 302. This causes the extension 203 to slide back and forth on the agitator 202 under the action of the third compression spring, thereby expanding the agitation range of the extension 203. This allows the extension 203 to more thoroughly agitate large impurities on the treatment tank 101, further ensuring that large impurities do not affect the normal flow of subsequent wastewater and guaranteeing a long-term filtration effect.

[0065] like Figure 5 , Figure 6 , Figure 8 As shown:

[0066] The device also includes a plurality of protrusions 205 fixed to the push plate 204, and a striking head 303 fixed to the contact head 302.

[0067] When the stirring part 202 rotates normally, and the extension part 203 rotates synchronously with the stirring part 202, the multiple extension parts 203 on the push plate 204 will contact the contact head 302 in sequence, thereby causing the push plate 204 to be pressed multiple times. This allows the extension parts 203 to slide repeatedly at high frequency during rotation, which further efficiently stirs up large impurities, preventing them from being placed in a relatively static position on the treatment box 101 for a long time. This further ensures that large impurities will not affect the normal flow of sewage poured in later.

[0068] When dumping large impurities from the salvage arc plate 502, the push rod 301 can be operated to slide on the slide plate 201, and then the striking head 303 can be used to strike the salvage arc plate 502 multiple times, so that the salvage arc plate 502 will vibrate slightly, thereby allowing the large impurities adhering to the salvage arc plate 502 to be shaken off smoothly, facilitating the complete discharge of large impurities.
