Abstract
The utility model relates to a device is dealt with to mud. Be oblique hopper -shaped including sludge tihckener 1, sludge drying field 7, sludge tihckener 1's bottom 6, to be supernatant overflow weir 2 are equipped with with supernatant backward flow 7 sides of mouthful 3, sludge drying field sludge tihckener 1's upper portion filters liquid counter -flow vat 8, sets up mud delivery pipe 5 between the mud discharge port of sludge tihckener 1's bottom 6 and sludge drying field 7, the level of supernatant overflow weir 2 is higher than the level of the mud discharge port of sludge drying field 7. The utility model discloses at mud pipe road of sludge tihckener bottom design, it is the fluidic characteristics here to utilize mud, gives a liquid level poor when pond under construction concentrated and drying bed, and the mud dope does not need any extrinsic motive through discharge the sludge drying field from the stream mode, has practiced thrift the installation and operation cost of pneumatic diaphragm pump.
Description
Technical field
The utility model belongs to pollution plot technical field, is specifically related to the sludge treatment device produced in a kind of landfill leachate treatment process.
Background technology
The mud produced in landfill leachate treatment process generally adopts mud nature drying and other treatment.Sludge drying bed is that an investment is low, manages simple practical technique, and general treatment scheme is sludge thickener-pneumatic diaphragm pump-sludge drying bed-sludge disposal.Enter the mummification speed that mud concentration badly influences mud, mud liquid must advanced sludge thickener carry out concentrated after be discharged into sludge drying bed and carry out mummification, it is tipping bucket shape below existing sludge thickener, be convenient to the mud that concentrating and precipitating gets off and can focus on the spoil disposal mouth of pipe bottom pond, overflow weir and overflow groove are arranged at top, make supernatant liquor overflow to overflow groove and are back to equalizing tank through return line and again process.Due to the many and complicated of the impurity in percolate, pipeline is easy to blocking, just forms the too high situation of load like this to pneumatic diaphragm pump, the motor feels hot rapid wear.
Utility model content
The purpose of this utility model is the deficiency existed for existing sludge treatment device, provides a kind of sludge treatment device.
Technical solution of the present utility model is: a kind of sludge treatment device, comprise sludge thickener, sludge drying bed, the bottom of sludge thickener is tipping bucket shape, the top of sludge thickener is supernatant liquor overflow weir and supernatant liquor refluxing opening, between the bottom of sludge thickener and the mud discharging mouth of sludge drying bed, arrange mud discharging pipe, the level height of supernatant liquor overflow weir is higher than the level height of the mud discharging mouth of sludge drying bed.
The side of described mud discharging pipe arranges inlet pipe, holes at the bottom inlet place of mud discharging pipe, and inlet pipe inserts mud discharging pipe from drill hole.
Described sludge thickener is half buried.
The beneficial effects of the utility model are: the thickened sludge of sludge thickener generally adopts pneumatic diaphragm pump to be transported to drying bed, the utility model is at sludge thickener bottom design shore pipe road, mud is utilized to be the feature of fluid at this, a liquid level difference is given when building concentration basin and drying bed, mud dope is by being discharged into sludge drying bed from stream mode, without any need for extrinsic motive, save the installation and operation cost of pneumatic diaphragm pump, in daily administration, also only can prevent line clogging with the mud that irrigation of trachea loosens in pipe.
Accompanying drawing explanation
Fig. 1 is sludge treatment device structure iron.
1. sludge thickeners in figure; 2. overflow weir; 3. supernatant liquor refluxing opening; 4. inlet pipe; 5. mud discharging pipe; 6. bottom; 7. sludge drying bed; 8. cleaner liquid backflash.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of sludge treatment device, comprise sludge thickener 1, sludge drying bed 7, the bottom 6 of sludge thickener 1 is tipping bucket shape, the top of sludge thickener 1 is supernatant liquor overflow weir 2 and supernatant liquor refluxing opening 3, sludge drying bed 7 is other is provided with cleaner liquid backflash 8, between the bottom 6 and the mud discharging mouth of sludge drying bed 7 of sludge thickener 1, arrange mud discharging pipe 5; The level height of supernatant liquor overflow weir 2, generally can higher than 500mm. higher than the level height of the mud discharging mouth of sludge drying bed 7
Arrange inlet pipe 4 on the side of mud discharging pipe 5, hole at the bottom inlet place of mud discharging pipe 5, inlet pipe 4 inserts mud discharging pipe 5 from drill hole.
Sludge thickener 1 adopts half buried, general underground pond height 2000mm, local part 2000mm.The bottom 6 of sludge thickener 1 is tipping bucket shape, is convenient to the mud that concentrating and precipitating gets off and can focuses on the spoil disposal mouth of pipe bottom pond.Overflow weir 2 and overflow groove are arranged at top, make supernatant liquor overflow to overflow groove and are back to equalizing tank through return line and again process.
Sludge drying bed 7, all build ground in, inside fills out three-layer filter, bottom filling coarse fodder fitros or pebbles, and central filler is fine filtering stone slightly, paving thin river, surface sand.Examine filter refuse landfill present position remote, place is more abundant, and it is simple to save operation cost and way to manage, only needs to determine natural air drying, regularly clear mud, therefore at this selection sludge drying bed 7 dewatered sludge.
Overflow weir 3, after mud dope is discharged into sludge thickener 1, mud natural sedimentation is to bottom 6, and supernatant liquor overflows to overflow groove from overflow weir 3 and gets back to equalizing tank through return line.
Mud discharging pipe 5, sludge settling, to bottom 6, is discharged into sludge drying bed 7 through mud discharging pipe 5.Mud discharging pipe 5 one kinds of pipeline modes are: comprise and to be positioned at bottom tipping bucket shape the level pipe below 6, the vertical tube perpendicular to level pipe, the delivery pipe that vertical tube top is connected with mud discharging mouth.The mode of mud discharging pipe 5 of the present utility model can be various ways, is not limited to above-mentioned a kind of mode.
Inlet pipe 4, for preventing mud blocking pipeline when conducting oneself with dignity discharge, manual gas flushing mud discharging pipe 5, also can discharge mud simultaneously.
Cleaner liquid backflash 8, the sludge liquid of sludge drying bed 7 is entered filtering layer and is filtered, and cleaner liquid is discharged into cleaner liquid backflash 8 end of from, and mud is dammed natural mummification on filtering layer.
The utility model make use of supernatant liquor overflow weir 2 and the liquid level difference of sludge drying bed 7, achieves deadweight spoil disposal.
