Abstract
The invention discloses an efficient treatment method for sludge. A water distribution pipe, a micro-hole filter brick layer and a slag layer are respectively laid on a sludge drying bed from bottom to top. The water distribution pipe is connected with a suction filter device. Sludge is placed in the sludge drying bed, the suction filter device is started to suck water and the water after suction filtration is delivery to a sewage adjusting pool. After the suction filtration is finished, the dried sludge and the slag layer are delivered to a sludge delivery vehicle through a clamshell crane and delivered outside. Due to adoption of the suction filter device, sludge treatment load can be greatly improved and sludge drying speed and dewatering effect are facilitated. The sludge drying bed is divided into over two areas in a separating mode, operation can be alternate or the sludge in different batches can be treated. A backwashing device is further arranged and used for backwashing sludge blocking after the micro-hole filter brick layer is blocked and a good working condition of the micro-hole filter brick layer can be guaranteed. In addition, the sludge drying bed is simple in structure arrangement and has great practical significance on saving occupied area, saving investment, saving energy and reducing consumption.

Technical field
The present invention relates to technical field of sludge treatment, particularly relate to a kind of high-efficient treatment method of mud, and sludge drying bed.
Background technology
The mud that produces in sewage treatment process, its water ratio are the short texture of the granular or flocculent substance of flow state 97%～99.6%, and is bulky, is difficult to dispose dissolve, and therefore need carry out sludge dewatering in sludge treatment or in disposing.Concentrated is mainly interstitial water in separated sludge, dehydration is mainly that the planar water in mud and capillary water are separated, this part water accounts for 15%～25% of total Water in mud, therefore, mud is after dehydration, before its volume reduces to and concentrates 1/10 reduces to 1/5 before dewatering, and greatly reduces the difficulty of follow-up sludge disposal.The main processing mode of sludge dewatering is mummification and mechanical dehydration, and the main processing structures of sludge drying are drying beds, but traditional drying bed or be to choose directly that the nature soil property is difficult for infiltration, area that ground water table is low is directly done sludge drying bed and used; Also just by simply building and laying, cause mummification speed slow, costs and poor dehydration results, floor space is large.
Summary of the invention
Technical problem to be solved by this invention be overcome that the mummification speed of existing mud is slow, costs and poor dehydration results, defective that floor space is large, a kind of high-efficient treatment method and sludge drying bed of mud are provided, can greatly improve the sludge treatment load, advance mummification speed and the dehydrating effect of mud, for saving floor space, save investment, energy-saving and cost-reducingly having a realistic meaning.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
The high-efficient treatment method of mud of the present invention: sludge drying bed is laid respectively water distributing pipe, micropore filter block layer and slag layer from below to up, water distributing pipe is connected with pumping and filtering device, mud is placed in sludge drying bed, opening pumping and filtering device draws water, the water of suction filtration is delivered to the sewage equalizing tank, after suction filtration finishes, by clamshell-equipped crane, the mud of mummification is delivered to the tipper outward transport together with slag layer.
The high-efficient treatment method of above-mentioned mud at the other end connection backwashing equipment of water distributing pipe, after micropore filter block layer stops up, is opened the backwashing equipment backwash and is cut dirt in slag layer and clear up.
Further, the high-efficient treatment method of aforementioned mud, described micropore filter block layer is laid on the filtering layer support, and is provided with fender bracket on micropore filter block layer top to prevent grab bucket damage micropore filter block layer.
Preferably, the high-efficient treatment method of aforementioned mud, the thickness of described micropore filter block layer is 0.1～0.5m, filter opening≤1mm, the thickness of slag layer are 0.1～0.15m.
Aforesaid sludge drying bed is divided into plural zone, can takes turns the mud that changes jobs or process different batches.
The present invention also provides sludge drying bed used in the aforementioned processing method, sludge drying bed 1 is equipped with water distributing pipe 3, micropore filter block layer 9 and slag layer 10 from bottom to up, water distributing pipe 3 is connected with pumping and filtering device 4, pumping and filtering device 4 connects rising pipes 5, is provided with into mud pipe 2 in the upper end of the enclosure wall 8 of sludge drying bed 1.
Above-mentioned sludge drying bed is connected with backwashing equipment 6 at the other end of water distributing pipe 3.Described micropore filter block layer 9 is installed on filtering layer support 11, and establishes fender bracket 12 on micropore filter block layer 9 top.Sludge drying bed 1 is equipped with clamshell-equipped crane 7.Described sludge drying bed 1 is divided into plural zone.
compared with prior art, in the high-efficient treatment method of mud of the present invention owing to having adopted pumping and filtering device, can greatly improve the sludge treatment load, thereby advance the speed of sludge drying and the effect of dehydration, sludge drying bed is divided into plural zone, can take turns the mud that changes jobs or process different batches, backwashing equipment further is set, the backwash that can be used for after micropore filter block layer stops up cuts dirt, guarantee that micropore filter block layer is in good working order, in addition, sludge drying field structure provided by the invention arranges simply, the present invention is for saving floor space, save investment, save energy and reduce the cost and have realistic meaning.
