By setting up the screenings separation tank 27, the connecting pipe 29, and the basket 28, it is convenient to process the separated impurity solids.

[0026] The coagulation zone 3 is connected to the media addition zone 4. A circulation pump 61 is installed at the bottom of the sedimentation zone 6. A sludge pump 73 is installed on the sludge temporary storage zone 7. A sewage discharge pipe 74 is installed on the sludge pump 73. The media addition zone 4 is connected to the flocculation zone 5.

[0027] The bottom of the sedimentation zone 6 is provided with a sludge scraper 64, a sludge hopper 65, a first sludge pipe 66 and a second sludge pipe 67.

Thus, the integrated medium sedimentation equipment has the effect of avoiding blockage of pipes and pumps.

[0029] Working principle: Wastewater enters the rotary drum microfilter 2 through the inlet pipe 11. A rotary drum screen 21 is installed in the center of the microfilter. The rotary drum screen 21 rotates slowly under the drive of the drive motor 22. Wastewater enters the interior of the rotary drum screen 21 and is filtered by the rotary drum screen 21. After being filtered by the rotary drum screen 21, the wastewater enters the coagulation zone 3 through the connecting pipe 23. The garbage in the wastewater is intercepted by the rotary drum screen 21. The operator adds coagulant to the coagulation zone 3. Under the action of the first agitator 31, the wastewater is quickly mixed and undergoes a chemical phosphorus removal reaction to form small particles.

[0030] Next, the wastewater flows into the medium addition zone 4. At the top of the medium addition zone is a hydrocyclone 41. The sludge and medium mixture drawn from the bottom circulation pump 61 of the sedimentation zone 6 undergoes a separation process in the hydrocyclone 41. The medium flows back into the addition zone 4. Under the action of the second agitator 42, the medium and wastewater are quickly and evenly mixed. The sludge separated by the hydrocyclone 41 flows into the sludge temporary storage zone 7. The sludge is transported to the sludge receiving unit outside the main body of the equipment 1 for further processing through the sludge pump 73 and the sewage pipe 74 located in the sludge temporary storage zone 7.

[0031] The wastewater from media addition zone 4 then enters flocculation zone 5, where a polymeric flocculant is added. Under the stirring action of the third agitator 51, the media and impurities quickly form easily precipitated flocs. The wastewater then enters sedimentation zone 6, where most of the flocs gradually settle to the bottom of the tank, while a small number of unsettled flocs are intercepted by the inclined pipe 62. At the top of sedimentation zone 6, clear water is collected in the outlet channel 63 and enters the subsequent treatment unit through the outlet pipe 8.

[0032] The sludge and media mixture at the bottom of sedimentation zone 6 is collected into sludge hopper 65 by scraper 64. Sludge hopper 65 is connected to circulation pump 61 through first sludge pipe 66. Circulation pump 61 and second sludge pipe 67 transport the sludge and media mixture to hydrocyclone 41 for separation. Finally, the sewage is filtered into clear water, which is discharged through outlet pipe 8. Part of the clear water is pressurized by branch pipe 81 and booster pump 10 to flush drum screen 21, directly removing impurities and solids from the sewage. This treatment of impurities and media mixtures avoids caking of the media and impurities mixture, thus preventing pipe and pump blockage.
