Embodiment 1

[0041] A kind of glue production water treatment process equipment, such as figure 1 As shown, it includes a mixing tank 1 and a stacked screw filter press. When in use, inject raw water and flocculant into the mixing tank 1 . The mixing tank 1 fully stirs the raw water and the flocculant, so that the particles in the raw water are fully combined. Afterwards, the material inside the mixing tank 1 is injected into the screw filter press. The stacked screw filter press filters the material, so that the water and the combined relay phase are separated to meet the national discharge requirements.

[0042] The stacked screw filter press includes a mud feeding box 2, a casing 3 and a mud discharging box 4 arranged in sequence. During use, the water in the raw water is discharged from the casing 3, and the particles combined in the raw water are discharged from the mud discharge box 4.

[0043] Such as figure 2 As shown, the housing 3 is provided with a fixed plate 5 and a mova...

Embodiment 2

[0053] A kind of use method of the production water treatment process equipment of glue as described in embodiment one, comprises the steps:

[0054] Step 1: Inject raw water of quality M into the mixing tank;

[0055] The second step: add 0.25%M-0.35%M polyacrylamide to the mixing tank;

[0056] The third step: the concentration of adding 0.2%M-0.4%M in the mixing tank is 20% ferric chloride solution;

[0057] Step 4: Use a mixing bucket to stir for 5 minutes, so that some impurities in the raw water can be flocculated;

[0058] Step 5: Add caustic soda or sulfuric acid to the mixing tank to adjust the pH to 6-8;

[0059] Step 6: Stand for 3 minutes;

[0060] Step 7: Add 0.25%M-0.5%M polyaluminum chloride to the mixing tank;

[0061] Step 8: Use a mixing bucket to stir for 5 minutes, so that some impurities in the raw water can be flocculated;

[0062] Step 9: Inject the material in the mixing tank into the screw filter press for pressure filtration.

Abstract

The invention provides a glue production water treatment process equipment and using method thereof, comprising a mixing tank and a stacked screw filter press, wherein the stacked screw filter comprises a mud feeding box, a shell and a mud discharging box arranged in sequence; A fixed plate and a movable plate are arranged at intervals in the shell, and a screw shaft is connected to the shell for rotation, and a spiral piece is arranged on the outer peripheral wall of the screw shaft, and the spiral piece conflicts with the inner ring of the movable plate; a power supply and a power supply are embedded in the movable plate. The electric heating wire is arranged along the circumference of the movable plate, and the two ends of the electric heating wire are respectively connected to the positive and negative poles of the power supply. The power supply supplies power to the electric heating wire, and the electric heating wire heats the movable plate to accelerate the evaporation of water, so that the impurities can be dried faster, so that the equipment used in the water treatment process of glue production can have a higher dehydration efficiency. During the rotation of the helical piece, the helical piece can push the movable plate to move between the two fixed plates, so as to remove some impurities attached to the fixed plate.

Description

technical field [0001] The present invention relates to the treatment of production wastewater of glue, in particular, relates to equipment for the production water treatment process of glue and its use method. Background technique [0002] At present, the Chinese patent with the notification number CN201525798U discloses a screw-stacked sludge dewatering machine, which includes a casing, a fixed plate, a movable plate, a screw shaft, a screw blade, an adjustment block and a screw. There are mud feeding boxes and mud discharging boxes on both sides of the shell respectively. The fixed plate and the movable plate are arranged at intervals inside the shell, and the fixed plate and the movable plate are arranged concentrically. The screw shaft passes through the center of the fixed plate and the movable plate, and the screw piece is fixedly connected to the outer peripheral wall of the screw shaft, and the pitch of the screw piece gradually decreases from the side of the mud b...
