[0002] Multi-stage water treatment uses physical, chemical and biological methods to purify wastewater. First, large particles and suspended matter are removed through physical treatment such as screens and grit chambers. Next, flocculants and precipitants are used to aggregate and settle tiny particles and dissolved substances in the chemical treatment stage. Then, microorganisms are used to decompose organic matter and nutrients in the biological treatment stage. Finally, residual pollutants are removed through ecological treatment such as artificial wetlands to ensure that water quality meets standards.

Under the meshing action of the gear 205, the two push plates 207 are driven to rotate in opposite directions inside the medicine box 203. During this period, the medicine above the medicine box 203 falls into the gap between the two push plates 207. After the push plates 207 intercept the medicine above, the medicine in the gap is introduced into the sewage treatment tank 201 from the bottom of the medicine box 203.

After adjusting the valves at the connection between the sewage treatment tanks 201 one by one, the sewage flows into different sewage treatment tanks 201 and undergoes different reactions. Finally, the sewage is discharged from the output pipe 202.

[0034] Finally, when it is necessary to clean the floating objects inside the input pipe 101, the motor 103 is started to drive the winding wheel 104 to rotate, the traction rope 105 is rolled up and drives the mounting frame 107 and the mounting plate 108 to rise through the connecting hook 106, and then the binding between the traction rope 105 and the connecting hook 106 is released, the screw 112 is screwed out, and the mounting plates 108 are pulled out one by one from the side of the mounting frame 107 upward, and the baffle 109 is exposed, so that the floating objects hanging on the spikes 110 can be cleaned conveniently.
