Abstract
The utility model relates to a rapid sludge percolation and desiccation pond. The problems that only a small quantity of free water and interstitial water in sludge can be removed through a conventional sludge treatment technology, and a treatment device is generally large in occupied area are to be solved. The rapid sludge percolation and desiccation pond is characterized in that a sludge distributing pipe which is provided with through holes and horizontally arranged, an upper coarse sand layer of filter cloth, the filter cloth, a lower coarse sand layer of the filter cloth, a small-particle-size filter material layer, a medium-particle-size filter material layer, an aerator pipe which is provided with through holes and horizontally arranged, a large-particle-size filter material layer, a drain pipe horizontally arranged and a water collecting pipe which is provided with through holes and horizontally arranged are sequentially arranged in the desiccation pond from top to bottom. The rapid sludge percolation and desiccation pond has the advantages of being simple in installation, operation and maintenance technology, small in occupied area, low in operation energy consumption, , easy to manage automatically and the like, and chemical adding is avoided.
Description
Technical field
The utility model relates to quick diafiltration and the mummification of the biochemical sludge that produces after biochemical sludge quick diafiltration mummifying pool, especially the small sewage treatment plant biochemical treatment in biochemical sewage treatment process.
Background technology
Biochemical sludge is carried out to drying and other treatment, become the important component part of sewage treatment process at present; Yet conventional sludge disposal technology, as mud is concentrated, sludge press filtration etc., often can only remove free water a small amount of in mud and interstitial water, poor in conjunction with the removal effect of water to most of capillary water, surface adsorption water and internal water etc. in mud; And conventional sludge disposal technology often exists, and floor space is large, facility investment and the deficiency such as working cost is high, chemical agent dosage large and disposing sludge solid content is low, be unfavorable for the storage, transportation of biochemical sludge and further advanced treatment.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is to provide the quick diafiltration mummifying pool of a kind of mud.
The purpose of this utility model is achieved in that it comprises mummifying pool, it is characterized in that: in mummifying pool, be successively from top to bottom, horizontally disposed tape punching cloth mud pipe, coarse sands layer on filter cloth, filter cloth, coarse sands layer under filter cloth, small particle size filter material layer, middle particle diameter filter material layer, horizontally disposed tape punching aeration tube, large particle diameter filter material layer, water pipe is received in horizontally disposed water shoot and horizontally disposed tape punching, wherein cloth mud pipe with enter mud pipe and form threeway, tape punching aeration tube and inlet pipe form bend pipe, tape punching receipts water pipe and water shoot are end to end in mummifying pool, the water port of water shoot is placed in outside mummifying pool, said perforation refers to uniform several holes on body.Water shoot is higher than receiving water pipe, and in order to forming water seal, backflow phenomenon appears in the outer draining that prevents mummifying pool.
To entering mud pipe, inject the higher biochemical sludge of water ratio, blower fan is to inlet pipe air blast.Enter into the mud of mud pipe self gravitation and from above under the effect of mud pressure, water in mud flows out from its perforation, by filter cloth, each filter material layer, flow to successively the below of mummifying pool from top to bottom, by receiving the perforation of water pipe, enter successively receipts water pipe and water shoot and discharge from filter tank through water shoot.In this process, by filter cloth, be trapped in its surperficial mud, under the air-flow making progress at boring aeration pipe blows, constantly obtain mummification, when moisture percentage in sewage sludge is reduced to 70～75%, by scraping mud equipment, from the quick diafiltration mummifying pool of mud, separate, carry out next step advanced treatment.Biochemical sludge all the time in aeration state, has effectively stoped the generation of the unpleasant gas of anaerobism at whole drying process.
Compared with prior art, positively effect of the present utility model is: mummification is effective, and the sludge volume after mummification reduces greatly, is conducive to storage, transportation and the further advanced treatment of biochemical sludge; The utility model is simple in structure, and installation, operation and maintenance technology are simple, and floor space is little, operation energy consumption is low, without pharmaceutical chemicals, adds, is easy to automatic management.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, further illustrate the utility model.
Fig. 1 is structural representation of the present utility model.
Embodiment
In mummifying pool 13, be successively from top to bottom, water pipe 11 is received in coarse sands layer 6 under coarse sands layer 4, filter cloth 5, filter cloth on horizontally disposed tape punching cloth mud pipe 3, filter cloth, small particle size filter material layer 7, middle particle diameter filter material layer 8, horizontally disposed tape punching aeration tube 9, large particle diameter filter material layer 10, horizontally disposed water shoot 1 and horizontally disposed tape punching, wherein cloth mud pipe with enter mud pipe and form threeway, tape punching aeration tube and inlet pipe form bend pipe, tape punching receipts water pipe and water shoot are end to end in mummifying pool, and the water port of water shoot is placed in outside mummifying pool; Said perforation refers to uniform several holes on body.Water shoot is higher than receiving water pipe, and in order to forming water seal, backflow phenomenon appears in the outer draining that prevents mummifying pool.
To entering mud pipe, inject the higher biochemical sludge of water ratio, blower fan is to inlet pipe air blast.Enter into the mud of mud pipe self gravitation and from above under the effect of mud pressure, water in mud flows out from its perforation, by filter cloth, each filter material layer, flow to successively the below of mummifying pool from top to bottom, by receiving the perforation of water pipe, enter successively receipts water pipe and water shoot and discharge from filter tank through water shoot.In this process, by filter cloth, be trapped in its surperficial mud, under the air-flow making progress at boring aeration pipe blows, constantly obtain mummification, when moisture percentage in sewage sludge is reduced to 70～75%, by scraping mud equipment, from the quick diafiltration mummifying pool of mud, separate, carry out next step advanced treatment.Biochemical sludge all the time in aeration state, has effectively stoped the generation of the unpleasant gas of anaerobism at whole drying process.
