Because the silt settled at the silt outlet pipeline 26 contains a large amount of water, the silt is directly introduced into a filter press for filter pressing, so that the workload of the filter press is increased, and in order to simplify the subsequent filter pressing operation and improve the treatment efficiency of the filter press, an extrusion device 25 is arranged at the bottom of the second sedimentation tank 22, wherein the extrusion device 25 comprises a screw chamber 251, an extrusion screw 252, an extrusion screw driving motor 253 and a silt discharging chamber 254; the screw chamber 251 is cylindrical, is arranged at the bottom of the second sedimentation tank 22 and is communicated with the second sedimentation tank 22, an extrusion screw 252 is arranged in the screw chamber, and the outer diameter of the extrusion screw 252 is consistent with the inner diameter of the screw chamber; an extrusion screw driving motor 253 is arranged at one end of the extrusion screw 252, and the extrusion screw 252 can freely rotate under the driving of the extrusion screw driving motor 253; the end of extruding of screw rod room 251 is equipped with silt discharging chamber 254, with screw rod room 251 is integrative design, silt discharging chamber 254 is the round platform form, and the great one end of round platform diameter links together with the extrusion end of screw rod room 251, and the less one end of diameter meets with silt export 26, and such design makes silt when passing through screw rod room 251, owing to extrude more moisture of screw rod 252 extrusion effect discharge, and when extruding screw rod 252 and transporting silt to silt discharging chamber 254 room, owing to the little round platform form design in the big end back before silt discharging chamber 254, make silt receive the extrusion once more when passing through silt discharging chamber, further discharge the moisture content in the silt, thereby make the silt water content of exporting 26 exhaust from silt less.

After sedimentation separation is carried out in the sedimentation tank 2, discharged silt is introduced into a filter press 3 (purchased from Guangzhou city green Torpo environmental protection machinery Co., Ltd., model 3DYQN3500ZP1, effective width of a filter belt is 3500mm) for filter pressing, moisture squeezed out by the filter press 3 returns to the sedimentation chamber 2, supernatant in the sedimentation chamber 2 enters the water storage tank 4 through a pipeline, density in the water storage tank 4 is adjusted according to density display of the first density real-time monitoring area 5, density in the water storage tank 4 is ensured to meet the density required by tank water in the first cleaning tank 1 through density monitoring of the second density real-time monitoring area 6, and then a suction pump 7 is started to enable the water in the water storage tank 4 to enter the first cleaning tank 1 through a water inlet pipe 12.

Further, the first density real-time monitoring area 5 and the second density real-time monitoring area 6 are both density monitoring areas formed by separating a sieve plate, and a liquid densimeter is arranged in the density monitoring areas. The design of the density monitoring area ensures that the water entering the density monitoring area through the sieve plate is in a relatively static state, thereby being convenient for measuring the density of the water.

Furthermore, the liquid densimeter is purchased from Beijing Shitong scientific and technical limited company, and has the model of TQ-880, and not only can detect the density of water, but also can detect the concentration of the medicament in the water, so that when the density of the water storage tank 4 is adjusted, the addition amount of the medicament only needs to be determined according to the measured concentration, and the liquid densimeter is accurate and convenient.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the embodiments disclosed, but is capable of numerous equivalents and substitutions without departing from the spirit of the invention, and such equivalents and substitutions are intended to be included within the scope of the invention as defined by the appended claims.
