[0013] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0014] Firstly, in the present invention, the wastewater first flows into the cyclone separator, and the cyclone separator separates the large sand and gravel in the wastewater due to the centrifugal force. After separation, it is transported to the high-speed sedimentation device to flocculate the sewage. For the sediment in the wastewater, the magnetic loading separation device can combine the external magnetic frame carrier with the rock powder and other pollutants to flocculate and combine the load-bearing flocs, and transport the sludge to the sludge storage tank. The separated water is discharged to the outside through the clean water outlet device, thereby realizing the treatment of the curtain grouting wastewater.

[0015] Secondly, in the present invention, the medicine inlet pipe transports the wastewater treatment medicine to the high-speed sedimentation tank, and the rotating motor drives the rotating blades to rotate, which can stir the wastewater in the high-speed sedimentation tank, so that the wastewater and the medicine are fully stirred, and the wastewater is purified. After treatment, the wastewater is transported to the sedimentation tank through the first water inlet pump, and a plurality of cyclone inclined tube settlers separate the solid and liquid in the wastewater. After separation, the sludge is transported to the discharge hood, and then transported to the sludge storage tank through the first mud outlet pipe, and the liquid wastewater is transported to the separation box, thereby realizing the separation treatment of solid and liquid in the curtain grouting wastewater.

[0016] Thirdly, in the present invention, the wastewater is transported to the separation box through the water inlet pipe by the second water inlet pump, and at this time, the flocculant and the coagulant aid are transported to the separation box through the feeding pipe, and the driving motor drives the driving gear to rotate, and the rotation of the driving gear drives the two separation gears to rotate, thereby driving the two separation augers to rotate in the separation box. The rotation of the separation augers can make the flocculant and the coagulant aid fully mixed with the wastewater. The magnetic loading separation device mainly utilizes flocculation technology to combine non-magnetic impurities with magnetic species, so as to accelerate the sedimentation of most impurities in the separation box, and then a small part of impurities with certain magnetism are separated by a high-gradient magnetic field to ensure high-precision filtration effect; specifically, flocculants and coagulants are added to the incoming water of the separation box to destroy the stable state of the colloidal particles in the water, and through the mutual collision and aggregation between the colloids and other particles, flocculent substances that are easy to separate from the water are formed. This part of suspended solids is first adsorbed on the magnetic powder loading, and is precipitated and separated from the water by gravity in the separation box; then it passes through the magnetic extraction filter, and under the action of the external magnetic field, a high gradient magnetic field is generated on the surface of the magnetic medium to capture and remove the suspended solid particles in the water. The sediment is separated from the magnetic powder and sludge by the magnetic drum separator, and the magnetic powder is recovered to the mixing tank for reuse. The separated sludge is discharged to the sludge storage tank through the second mud outlet pipe, which can achieve precipitation and separation of suspended solid particles in the wastewater and further purify the wastewater.

[0017] Fourthly, when the present invention dehydrates the sludge, the desludging cylinder works through two driving rods to make the desludging extrusion plate move downward in the desludging box. The desludging extrusion plate moves downward to dehydrate the water in the sludge through the dehydration plate. After squeezing, the water in the sludge flows into the lower part of the desludging box and is discharged to the outside through the discharge pipe. After the sludge is dehydrated, the mud discharge door is opened to discharge the dehydrated sludge to the outside, so that the water content in the sludge is compressed from 99% to less than 70%, and the volume is reduced by 1 / 30, which greatly saves the cost of transporting the sludge.

[0018] Fifth, when the present invention is squeezing the sludge, the bottom plate of the desludging extrusion plate will stick to the sludge. At this time, the working motor drives the scraper screw to rotate and drives the scraper plate to move back and forth on the sliding rod. The movement of the scraper plate drives the scraper sheet to move to scrape off the sludge stuck to the bottom of the desludging extrusion plate. After the sludge is scraped off, it is beneficial to the next dehydration and extrusion of the sludge, and prevents the sludge from forming lumps at the bottom of the desludging extrusion plate, affecting subsequent use.
