The stud 201 is connected to one side of the surface of the tank body 1, the filter tank 202 is connected to one side of the surface of the tank body 1, the filter plate 203 is embedded in the tank body 1, the filter screen 204 is installed in the filter tank 202, a valve 205 is installed at one end of the filter tank 202, a slide 206 is connected to one side of the surface of the filter plate 203, a sealing strip 207 is connected to the other side of the surface of the filter plate 203, the surface of the sealing strip 207 is connected to the cover plate 208, and the surface of the cover plate 208 is connected to the cylinder 209. When it is necessary to treat wastewater, first The wastewater is first filtered through the filter plate 203, and some impurities in the wastewater can be precipitated and retained on the filter plate 203 through the fiber filter element. Then the wastewater enters the filter tank 202, and is filtered through the filter mesh 204. The activated carbon filter element adsorbs some harmful substances in the wastewater and retains them on the filter mesh 204. Finally, the filtered wastewater flows out through the valve 205. When the filtration is completed, the rotating cylinder 209 separates it from the stud 201, and then the cover plate 208 is removed. At this time, the filter plate 203 is pulled, and the filter plate 203 is pulled out of the tank body 1 through the slide bar 206, so that the filtered impurities can be cleaned or replaced for the next use, and the setting of the sealing strip 207 can prevent the wastewater from overflowing when it is inside the tank body 1.

[0022] Furthermore, the stud 201 is threadedly connected to the cylinder 209, and the internal material of the filter plate 203 is fiber. Through the setting of the filter plate 203, the fiber material of the filter plate 203 can filter out suspended matter, cotton wool and other impurities in the wastewater, and can perform the first filtration of the wastewater. When the filter plate 203 is pulled out from the inside of the tank body 1, the filtered impurities can be cleaned at any time for secondary use.

[0023] Furthermore, the filter plate 203 and the tank body 1 form a sliding relationship with each other. There are two groups of sliding bars 206. Through the arrangement of the sliding bars 206, when it is necessary to clean or replace the filter plate 203, the filter plate 203 can slide in the tank body 1 through the sliding relationship between the sliding bars 206 and the tank body 1, which is convenient for disassembly.

[0024] Furthermore, the internal material of the filter net 204 is activated carbon, and the sealing strip 207 fits tightly with the cover plate 208. Through the arrangement of the sealing strip 207, when the cover plate 208 is fixed at one end of the filter plate 203, at this time, the sealing strip 207 is located between the cover plate 208 and the filter plate 203 and fits tightly with the tank body 1, which can prevent the water in the tank body 1 from overflowing.

[0025] Furthermore, the filter net 204 fits tightly with the inner wall of the filter tank 202. Through the arrangement of the filter net 204, the activated carbon material of the filter net 204 can be used to adsorb the odor, organic pollutants, etc. in the water, giving full play to its functions of precipitating impurities and adsorbing harmful substances, and making the filtering effect superimposed.

[0026] Furthermore, the treatment mechanism 3 includes a water inlet 301, a tank cover 302, a mixer 303, a partition plate 304, a feeding port 305 and a sliding cover 306. One side of the surface of the tank body 1 is connected with the water inlet 301, one end of the tank body 1 is installed with the tank cover 302, the mixer 303 is installed inside the tank body 1, the partition plate 304 is connected inside the tank body 1, the feeding port 305 is opened on the surface of the tank cover 302, and the sliding cover 306 is connected inside the feeding port 305. Through the arrangement of the water inlet 301, the tank cover 302, the mixer 303, the partition plate 304, the feeding port 305 and the sliding cover 306, when it is necessary to treat the wastewater, first, the wastewater flows into the tank body 1 from the water inlet 301. Then, the sliding cover 306 can be slid to slide it into the tank cover 302 to expose the feeding port 305, and the relevant chemical reagents can be poured into the tank body 1 to be mixed with the wastewater to enhance the separation of harmful substances in the wastewater. After starting the mixer 303, the chemical reagents and the wastewater can be fully stirred and mixed, and the setting of the partition plate 304 can slow down the flow rate of the wastewater and increase the reaction and filtration time.

[0027] Furthermore, one side of the surface of the tank cover 302 fits with the tank body 1, and the sliding cover 306 and the tank cover 302 form a sliding relationship with each other. Through the arrangement of the mixer 303, when the wastewater enters the inside of the tank body 1, the relevant chemical reagents can be poured into the wastewater. At this time, the mixer 303 can be started to fully mix it with the wastewater, helping to separate the harmful substances in the wastewater and adsorb them on the filter plate 203.

[0028] Working principle: When wastewater needs to be treated, the wastewater first flows into the tank body 1 from the water inlet 301, and then the sliding cover 306 can be slid into the tank cover 302 to expose the feed inlet 305, and the relevant chemical reagents can be poured into the tank body 1 to mix with the wastewater to enhance the separation of harmful substances in the wastewater. After starting the mixer 303, the chemical reagents and wastewater components can be stirred and mixed, and the setting of the partition 304 can slow down the flow rate of the wastewater and increase the reaction and filtration time. Then the wastewater is first filtered by the filter plate 203, and some impurities in the wastewater can be precipitated by the fiber filter element and retained on the filter plate 203. The waste water then enters the filter tank 202, and is filtered by the filter screen 204. The activated carbon filter element adsorbs some harmful substances in the waste water and retains them on the filter screen 204. Finally, the filtered waste water flows out through the valve 205. When the filtering is completed, the rotating cylinder 209 separates it from the stud 201, and then the cover plate 208 is removed. At this time, the filter plate 203 is pulled, and the filter plate 203 is pulled out of the tank body 1 through the slide bar 206, so that the filtered impurities can be cleaned or replaced for the next use, and the setting of the sealing strip 207 can prevent the waste water from overflowing when it is inside the tank body 1.
