After the deceleration and sand removal of the flat flow pipe, the flow rate of the clear liquid is significantly reduced, and in the preferred embodiment, the flat flow pipe 3 is communicated with the sewer pipe 6 through an arc-shaped connecting pipe, so that the condition that the clear liquid stops and even flows back to the sand removal hole in the long-distance flat flow process is reduced.
The working process of the flume drainage system suitable for the solid waste leaching liquid in the preferred embodiment of the invention is as follows:
Under the action of the spiral guide plate 221 and the folds of the pipe main body 22, on one hand, vortex is formed by the leaching liquid main body, on the other hand, the speed reduction effect of the folds on the sediment particles with higher density is more remarkable, under the condition of the difference of the inner and outer speeds, the leaching liquid can be subjected to preliminary diversion, so that sediment turbid liquid can tend to flow into the filtering oil separation groove 4 along the inner wall, clear liquid can tend to flow into the flat flow pipe 3 for preliminary separation, and then more accurate solid-liquid separation is carried out in the flat flow pipe. Specifically, referring to fig. 1 to 3, the leachate of the solid waste is primarily separated in the diversion filter device 1, when the leachate passes through the diversion filter device 1, residues of large particles in the sediment are trapped by the diversion grating 11 on the inner wall of the diversion filter device 1, and fall on the bottom 12 to be collected, and due to a certain transverse offset between two acute angles of the diamond diversion grating 11 (i.e. two opposite angles of the diamond are not on the same vertical line), the leachate can enter the spiral pipe main body 22 of the diversion pipe 2 through the diversion grating 11 at a certain rotation angle (for example, a rotation angle of about 30 degrees), and the leachate forms spiral vortex in the pipe main body 22 under the action of the spiral diversion plate 221 in the pipe main body 22 through the diversion of the diversion grating 11. The spiral downward leachate is affected by centripetal force, and by the interception effect of folds on the inner wall of the pipe main body 22, the sediment turbid liquid with higher density (containing more sediment particles) and clear liquid flow down at different speeds, so that the first diversion is realized at the three-way pipe 21, wherein the sediment turbid liquid with low flow speed directly enters the filtering oil separation groove 4, and the clear liquid after primary diversion enters the flat flow pipe 3. The clear liquid with speed inertia in the advection pipe 3 can cross the first sand discharge hole 31, and the slowly flowing sediment turbid liquid can enter the turbid liquid area of the filtering oil separation groove 4 through the first sand discharge hole 31, so that the second diversion of the clear liquid and the sediment turbid liquid is realized. The clear liquid passing through the first sediment discharge hole 31 is decelerated in the deceleration section 33, sediment in the clear liquid is further decelerated and layered, is trapped and deposited in the deceleration section 33, gradually flows to the second sediment discharge hole 32 along with the driving of the supernatant liquid, and enters the turbid liquid area of the filtering oil separation groove 4, so that third diversion of the clear liquid and the turbid liquid is realized. The clear liquid which is divided by three times is directly discharged into a sewer pipe 6 through a flat flow pipe 3.
The bottom in the turbid liquid area of the filtering and oil separating tank 4 is inclined, and the bottom of the filter screen 42 does not circulate, so turbid liquid entering the filtering and oil separating tank 4 is deposited in the filtering and oil separating tank 4, sediment in the deposition can slowly gather in the sediment collecting device 5, and suspended matters of the solid waste leaching liquid can float upwards from the surface of the solid waste in the standing and depositing process. Because the bottom of the second baffle 42 is slightly lower than the lower end of the filter screen 42, along with the rising of the liquid level in the filtering and oil separating tank 4, suspended matters entering the surface layer of the sediment turbidity solution in the filtering and oil separating tank 4 from the three-way pipe 21, the first sand discharging hole 31 and the second sand discharging hole 32 are separated between the first baffle 41 and the second baffle 42, the pollution of the suspended matters to the filter screen 44 is reduced, the liquid in the middle layer enters the clear liquid area through the filter screen 44, and is discharged into the sewer pipe 6 along with the rising of the liquid level in the clear liquid area. If the treatment load in the filtering oil separation tank 4 is large, the supernatant and suspended matters on the upper layer overflow through the overflow platform 43, the coarse grille on the surface of the overflow inclined plane 44 disperses and entraps the large suspended matters, and the supernatant is introduced into the sewer pipe 6 from the overflow area, so that the sewer pipe 6 is not blocked due to water flow impact even in the case of large-load treatment.
The preferred embodiment of the invention avoids the problem of pipeline blockage, realizes the targeted treatment of the leaching liquid of the solid waste through diversion, further improves the shock resistance of a water tank drainage system and reduces the burden of subsequent treatment facilities.
