Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please refer to Figure 1 As shown, this application provides a wastewater treatment apparatus, comprising:

[0022] A filter tank 1 is connected to a sewage pipe. The filter tank 1 is equipped with an agitation component 2, a sieve plate 3, and a sludge scraping component 4. The agitation component 2 is used to break up impurities of different particle sizes in the sewage and form impurities of the same particle size. The sieve plate 3 is installed below the agitation component 2, and the sludge scraping component 4 is installed on the upper surface of the sieve plate 3. The sieve plate 3 is used to filter impurities, and the sludge scraping component 4 is used to remove the impurities remaining on the sieve plate 3.

The L-shaped scraper 17 is connected to the waterproof electric push rod 18. A solenoid valve is installed at the input end of the waste liquid pipe 19. The waste liquid pipe 19 is connected to the filter tank 1, and the position of the input end of the waste liquid pipe 19 is adapted to the position of the sieve plate 3. The L-shaped scraper 17 is in contact with the sieve plate 3.

[0025] It should be noted that in the filter tank 1, the untreated sewage flowing into the sewage pipe contains impurities of different particle sizes. At this time, the stirring blade 16 is turned on, so that the stirring blade 16 rotates inside the filter tank 1 to cut the impurities of different particle sizes. Multiple stirring blades can be set. The number and speed of the stirring blades are set according to the amount of impurities and the particle size to be cut. After the cutting is completed, the cutting action is completed along with the flow of sewage. Then, the sewage cut by the stirring blade 16 is filtered through the filter plate 3 to filter the impurities of different particle sizes in one go.

[0026] The sludge scraping assembly 4 operates intermittently by pushing and pulling the L-shaped scraper 17 with the waterproof electric push rod 18. The L-shaped scraper 17 adheres to the upper surface of the filter plate 3, pushing the impurities on the filter plate 3 to the inlet of the waste liquid pipe 19. The waste liquid pipe 19 is inclined downward so that the impurities flow into the waste liquid collection tank 20 through the waste liquid pipe 19.
