[0031] Working principle: First, the reactants required for treating chemical wastewater are added into the reactant adding inner cylinder 204 through the first reactant adding hole 202 and the second reactant adding hole 205. At this time, the water inlet pipe 4 switch is turned on, so that the chemical wastewater passes through the four-layer filter screen 502 set inside the large impurity filtering component 5. The four-layer filter screen 502 uses a variety of mesh screens with different apertures to screen the chemical wastewater, so that large impurities such as suspended matter are directly removed from the chemical wastewater. Then, the screened chemical wastewater will flow into the purification reaction tank body 1. At this time, the reactant adding inner cylinder 204 is rotated so that the second reactant leakage hole 206 is directly opposite to the first reactant leakage hole 206. Hole 203, at this time, the reactant in the reactant adding inner cylinder 204 will pass through the second reactant leakage hole 206 and the first reactant leakage hole 203, thereby flowing into the purification reaction tank body 1, at this time, the switch of the motor 301 is turned on, the operation of the motor 301 will drive the first gear 302 to rotate, and through the transmission of the second gear 303 and the third gear 306, the first stirring shaft 304, the first stirring head 305 and the second stirring shaft 307, and the second stirring head 308 can be driven to rotate, and the first stirring head 305 and the second stirring head 308 are used to stir the chemical wastewater and the reactant in the purification reaction tank body 1 to make them fully react;

[0032] Next, after sufficient stirring, turn off the switch of the motor 301, and let it stand. After the reactants react, the chemical wastewater can be degraded and layered, and the dirt will settle due to gravity. The clean water will float on the top of the purification reaction tank body 1. At this time, turn the threaded rod 603 to let the threaded rod 603 drive the blocking ball 604 to rotate, so that the blocking ball 604 is separated from the outlet pipe 601, so that the pipeline of the outlet pipe 601 is opened, and the purified water will be discharged through the outlet pipe 601. Finally, when there are too many impurities in the large impurity filtering component 5, at this time, by turning the control handle 506, the control handle 506 will drive the rotating shaft 504 to rotate the fixed block 505, so that the fixed groove 503 is free from the restriction of the fixed block 505, and the filter screen 502 can be taken out from the filter device housing 501 for cleaning or replacement. After cleaning or replacement, the filter screen 502 is placed in the filter device housing 501, and then the control handle 506 is rotated to make the fixed block 505 rotate at the top of the filter device housing 501 through the control handle 506 and the rotating shaft 504, so that the fixed block 505 is engaged in the fixed groove 503 to prevent it from falling out.
