DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Embodiment one:

[0037] Reference Figures 1-7 A sewage treatment equipment with a filter press filter, comprising a sewage preliminary filter tank 9 for preliminarily filtering sewage in sewage treatment, a filter press 1 for separating sludge from water, and an adsorption tower 11, wherein the sewage preliminary filter tank 9 is provided with a pretreatment tank 10 between the sewage preliminary filter tank 9 and the filter press 1, the adsorption tower 11 is connected with an MBR tank 12, and the filter press 1 is provided with a filter assembly 5, a vibration assembly 6, and a cleaning assembly 7.

[0038] The filter assembly 5 drives the extrusion plate 502 to extrude a plurality of filter plates 4 to form a filter cavity for sewage filtration operation through the telescopic cylinder 501.

[0039] The telescopic cylinder 501 is arranged at one side of the top end of the filter press 1, the extrusion plate 502 is fixedly connected with the execution end of the telescopic cylinder 501, a plurality of connecting ropes 503 are connected with both sides of the extrusion plate 502 and both sides of the plurality of filter plates 4, a limiting rod 504 is arranged at both sides of the top end of the filter press 1 and below the rail 701, both sides of the plurality of filter plates 4 and the extrusion plate 502 are movably connected with the limiting rod 504, a pumping pipe 901 is arranged between the sewage early-stage filter tank 9 and the pretreatment tank 10, a feed pump connecting pipe 2 is arranged at the end of the top end of the filter press 1 away from the telescopic cylinder 501, one end of the feed pump connecting pipe 2 away from the filter press 1 is connected with the pretreatment tank 10, and filter water conveying pipes 3 are arranged at both sides of the end of the filter press 1 close to the feed pump connecting pipe 2, and the other ends of the filter water conveying pipes 3 are connected with the adsorption tower 11.

[0040] The bevel gear set 605 is arranged in an "L" shape, the top end of the lead screw 606 is provided with a moving plate 607, the moving plate 607 is connected with the lead screw nut of the lead screw 606, and a plurality of electric vibrators 608 are equidistantly arranged on one side of the moving plate 607 close to the filter plate 4.

[0041] The bottom end of the filter press 1 is provided with a ground rail 8, and the top end of the ground rail 8 is provided with a mud collecting box 801 and a waste water collecting box 802, and a filter interception net 803 is arranged in the middle of the waste water collecting box 802.

[0042] In the embodiment, it should be noted that when the sewage is treated, the sewage to be treated is first poured into the sewage early-stage filter tank 9, the larger impurities in the sewage are screened and filtered through the inclined grid net plate in the sewage early-stage filter tank 9, at the same time, the sewage is desanded in the sewage early-stage filter tank 9, the larger suspended particles, sand and other impurities in the sewage are removed, so as to prevent these substances from entering the filter equipment, causing equipment wear or blockage, and affecting the filter efficiency and effect.

[0043] The pumping pipe 901 pumps the water source in the middle section of the sewage early-stage filter tank 9 into the pretreatment tank 10, according to the properties and components of the sewage, a suitable flocculating agent is selected and added to the pretreatment tank 10. The flocculating agent can make the fine suspended particles, colloids and other impurities in the sewage coagulate into larger flocs, so as to be intercepted by the filter medium in the subsequent filter process, improve the filtering effect, and reduce the moisture content of the filter cake.

[0044] When the sewage is filtered and treated, the telescopic cylinder 501 is started to drive the extrusion plate 502 at the execution end to move, the plurality of filter plates 4 are extruded, and the unfolded filter plates 4 are folded to form filter cavities.

[0045] In the sewage treatment, the sewage in the pretreatment tank 10 is connected through the feed pump connecting pipe 2, enters the filter press 1, and is subjected to pressure filtration in the filter cavities formed by the plurality of filter plates 4. The sewage is sent into the filter chamber at a certain pressure, the solid particles of the sewage are intercepted on the surface of the filter cloth of the filter plate 4 to form a mud plate, and the liquid passes through the filter cloth and is discharged through the flow channel on the filter plate 4 to become clean water. The filtered water is output through the filtered water delivery pipe 3 and enters the adsorption tower 11. The adsorption tower 11 is divided into two parts. The side close to the filtered water delivery pipe 3 is filled with activated carbon and other adsorbents. The organic matter, heavy metal ions and other pollutants in the sewage are adsorbed on the surface of the adsorbents, thereby further reducing the concentration of the pollutants in the sewage, improving the water quality and reducing the burden of subsequent biological treatment.

[0046] The side far from the filtered water delivery pipe 3 of the adsorption tower 11 is internally provided with an ion exchange resin column. When the filtered water passes through the resin column, the target ions exchange with the exchangeable ions on the resin to achieve the removal or recovery of the ions. For example, strong acid cation exchange resin can be used to remove calcium and magnesium ions in the sewage to achieve water softening; weak base anion exchange resin can be used to adsorb and remove nitrate and phosphate in the sewage.

[0047] Finally, the filtered water passing through the adsorption tower 11 enters the MBR tank 12, and the organic matter, ammonia nitrogen, total phosphorus and other pollutants in the sewage are removed through the degradation of microorganisms. The membrane assembly replaces the traditional secondary sedimentation tank to perform high-efficiency solid-liquid separation, thereby ensuring that the effluent water is stable and clear. The MBR process has high sludge concentration and long sludge age, high removal efficiency of pollutants, and can effectively meet the strict water quality discharge standard or achieve water reuse. Example Two

[0048] Different from example one, referring to Figures 1-3 The present embodiment further has the following further contents: the vibration assembly 6 is used to vibrate the plurality of filter plates 4 after the filter plates 4 are reset after filtration, so that the mud plate attached to the filter cloth of the filter plates 4 falls downward.

[0049] The side of the filter plate 4 close to the extrusion plate 502 is provided with a connecting block 601. The side of the connecting block 601 far from the filter plate 4 and located inside the shell of the filter press 1 is provided with a conveying chain 602. The inner ends of the conveying chain 602 are both provided with rotating gears 603. The top end of the rotating gear 603 far from the filter plate 4 is provided with an engaging gear 604. The top end of the engaging gear 604 is provided with a bevel gear set 605. The side of the bevel gear set 605 far from the engaging gear 604 is provided with a lead screw 606.

[0050] In this embodiment, it needs to be explained that when the sewage filtration is finished, the telescopic cylinder 501 drives the connected filter press plate 4 to expand, the connecting rope 503 limits the spacing between the filter press plates 4, and the filter press plate 4 close to the inlet pump end is fixedly connected to the end of the filter press 1, and the fixed filter press plate 4 group will not move as a whole with the contraction of the telescopic cylinder 501.

[0051] When the filter press plate 4 expands, the mud plate inside the cake is exposed, at this time, the mud plate collecting box 801 is moved to the bottom end of the filter press 1, when the filter press plate 4 expands, the connecting block 601 at the bottom end of the filter press plate 4 close to the extrusion plate 502 side drives the conveying chain 602 to move, and further drives the rotating gear 603 to rotate, so as to make the connecting gear 604 and the bevel gear set 605 rotate, realize the rotation of the lead screw 606, and make the moving plate 607 connected with the lead screw 606 nut close to the filter press plate 4, so that the electric vibrator 608 is close to the outside of the filter press plate 4, and the filter press plate 4 is vibrated to make the mud plate fall off.

[0052] Through the vibration operation of the electric vibrator 608, the vibration frequency is set in the resonance frequency interval of the filter press plate 4 and the mud cake, which effectively loosens the mud plate, so as to better fall off from the filter cloth of the filter press plate 4, enhances the vibration auxiliary debarking effect, improves the mud plate falling speed, and reduces the possibility of damage to the filter cloth.
