1) filtration treatment: the river bottom mud of absorption is transported to bed mud and enters treatment box into bucket, then from bed mud into bucket by slush pump Interior, bed mud is flowed along the drainage web plate being obliquely installed, and is introduced into filter chamber, by first in filter chamber wavy filtering The filtration treatment of plate intercepts sand particles, the suspended impurity in bed mud, and bed mud is then from the filtering wears groove on wavy filter plate Relaying is continuous to be flow at the wavy filter plate of second, will be remaining in bed mud by the further filtering of the wavy filter plate of second Sandstone further intercept filtering；

2) winding removal of impurities processing: the bed mud after the wavy filter plate of second is flowed out from filtering wears groove, is further continued for edge Drainage web plate be manoeuvred into winding it is intracavitary, winding element starting, rotating electric machine drive winding axis rotation, thus drive twine Two groups of winding bar groups on axis are rotated along the direction opposite with bed mud flow direction, right in the rotation process in winding bar group Bed mud is stirred, and increases the mobility of bed mud, while in whipping process, and around rod twines the polybag contained in bed mud, weeds Around, while the winding tooth in around rod further winds the suspended matter in bed mud, and in around rod rotation process, in bed mud Particle and impact block collide, and are further knocked crushing；

3) adsorption treatment: by winding chamber, treated that bed mud continues on that drainage web plate is mobile, enters in adsorbent chamber, bed mud The rotation of roller is driven in flow process, so that the magnetic stick of inhaling on roller rotates, stick is inhaled by magnetism, bed mud is carried out It is again stirring for, increases bed mud mobile performance, while magnetic inhale in stick rotation process adsorbs the magnetisable material carried in bed mud；

4) flocculation dewatering is handled: it is intracavitary that the bed mud after adsorption treatment continues to flow to flocculation, while flocculant is from flocculant Inlet tube enters in flocculation spray plate, then from the sprinkler head in flocculation spray board bottom face to be sprayed onto flocculation intracavitary, and enters flocculation chamber Interior bed mud contact, while the first stirring motor and the starting of the second stirring motor, drive the first agitating shaft and second to stir respectively The rotation of axis increases the mobility of bed mud, so that bed mud and flocculation to drive the rotation of the first agitator disk and the second agitator disk Agent is thoroughly mixed, while in the first agitator disk and the second agitator disk rotation process, drives crushing tooth rotation, will be residual in bed mud Remaining impurity particle crushes, and the rotation direction of the first agitating shaft and the flow direction of bed mud are identical in whipping process, and second The rotation direction of agitating shaft and the flow direction of bed mud by flocculation chamber treated bed mud from the open end for the treatment of box on the contrary, flow Out, it is flowed into collection device by the guidance of mud guiding plate and carries out subsequent processing；

5) cleaning and maintenance:

A, whenever treatment box work 30-60min after, bed mud pump stop working, manually to the impurity intercepted on wavy filter plate into Row recycling, and the magnetic magnetisable material adsorbed on stick of inhaling is recycled, while clean water enters from flocculant inlet tube It is sprayed again from sprinkler head, sprinkling cleaning is carried out to the surface of the first agitator disk and the second agitator disk；

B, it and removes contamination and component while starting, rotating electric machine stops after driving one group of winding bar group to turn to top first, then Rotary electric machine drives screw rod rotation, to drive dirt collecting box mobile toward winding bar direction, until the winding bar of dirt collecting box and top When group collision, rotary electric machine stops working, and then the piston rod elongation of lifting cylinder, drives brush holder to move down, until brush The bottom of hair group contradicts the around rod to top, and then the piston rod elongated electric brush frame of mobile cylinder is past moves right, bristle pack The substance brush wound in around rod and winding tooth is swept in dirt collecting box；

C, after cleaning acts at least 10 times mobile cylinder back and forth, mobile cylinder pushes brush holder to stop when being located at the top of dirt collecting box Only, then clean water enters in guide tank out of second water inlet pipe, then is flowed into spray boom from guide tank, from the water outlet of spray boom Hole sprays, and carries out flush clean to the bristle pack of two sides, the sundries of adhesion in bristle pack is washed into dirt collecting box, is then moved Cylinders retract drives brush holder to be moved to the leftmost side, so that the shower plate on the right side of brush holder is placed exactly in the top of dirt collecting box, connects Clean water entered in shower plate from the first water inlet pipe, then from spray hole spray to lower section around rod surface carry out flush clean, Sundries remaining in around rod is washed into dirt collecting box, then lifting cylinder drives brush holder to rise to initial position, then spiral shell Bar rotates backward, and drives dirt collecting box mobile toward the direction far from around rod；

D, after the cleaning for completing one group of winding bar group, rotating electric machine is restarted, and stops after driving another group of winding bar to turn to top Only, washing and cleaning operation is carried out then according to the cleaning process of first group of winding bar group.
