Abstract
The utility model discloses a sludge drying bed capable of efficiently treating sludge. A water distributing pipe, a micropore filter brick layer and a slag layer are arranged on the sludge drying bed from bottom to top, the water distributing pipe is connected with a suction filtration device, the suction filtration device is connected with a water outlet pipe, and a mud inlet pipe is arranged at the upper end of an enclosing wall of the sludge drying bed. Due to the fact hat the suction filtration device is adopted, sludge treatment load can be greatly improved, and accordingly sludge drying speed and dehydration effect are improved. The sludge drying bed is divided into more than two areas, work rotation or treatment of sludge of different batches can be carried out, a backwash device is further arranged and can be used for backwashing and sewage interception of the micropore filter brick layer after blocking, and the fact that the micropore filter brick layer is in a good working state is guaranteed. Besides, the sludge drying bed is simple in structure and is of practical significance for saving occupied areas, investment and energy and reducing consumption.
Description
Technical field
The utility model relates to technical field of sludge treatment, particularly relates to a kind of sludge drying bed that can efficiently handle mud.
Background technology
The mud that is produced in the 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.Concentrating mainly is the interstitial water in the separated sludge; Dehydration then mainly is that planar water in the mud and capillary water are separated, and this part water accounts for 15%～25% of Total Water in the 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.Sludge dewatering main processing mode 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, cause mummification speed slow just through simply building and laying, costs and poor dehydration results, floor space is big.
Summary of the invention
The utility model technical problem to be solved be overcome that the mummification speed of existing mud is slow, costs and poor dehydration results, defective that floor space is big; A kind of sludge drying bed that can efficiently handle mud is provided; Can greatly improve the sludge treatment load; Advance the mummification speed and the dehydrating effect of mud, for saving floor space, practice thrift investment, energy-saving and cost-reducingly having a realistic meaning.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The utility model can efficiently be handled the sludge drying bed of mud: 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 back flushing equipment 6 at the other end of water distributing pipe 3, after micropore filter block layer 9 stops up, opens the backwash of back flushing equipment and cuts dirty in slag layer 10 and cleaning.Said micropore filter block layer 9 is installed on the filtering layer support 11, and establishes fender bracket 12 to prevent grab bucket damage micropore filter block layer on micropore filter block layer 9 top.Sludge drying bed 1 is equipped with clamshell-equipped crane 7.The thickness of said micropore filter block layer is 0.1～0.5m, and filter opening≤1mm, the thickness of slag layer are 0.1～0.15m.Said sludge drying bed 1 is divided into plural zone, can take turns the mud that changes jobs or handle different batches.
Compared with prior art, owing to adopted pumping and filtering device, can greatly improve the sludge treatment load in the sludge drying bed of the utility model; 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 handle different batches; Back flushing equipment further is set; The backwash that can be used for after micropore filter block layer stops up cuts dirt, guarantees that micropore filter block layer is in good working order, in addition; The sludge drying field structure that the utility model provides is provided with simply, for saving floor space, practice thrift investment, energy-saving and cost-reducingly having a realistic meaning.

Embodiment
At first build the sludge drying bed of a pond shape by sludge quantity and sludge treatment load; Sludge drying bed is divided into two zone wheel and changes jobs; Each zone from down and on lay water distributing pipe, micropore filter block layer and slag layer respectively, water distributing pipe is connected with pumping and filtering device, connects back flushing equipment at the other end of water distributing pipe; Micropore filter block layer is laid on the filtering layer support, and is provided with fender bracket to prevent grab bucket damage micropore filter block layer on micropore filter block layer top.Mud is placed in the sludge drying bed; Open pumping and filtering device and draw water, the water of suction filtration is delivered to the sewage equalizing tank, when the proofing unit of pumping and filtering device detect water outlet when all transferring gas to suction filtration finish; Through clamshell-equipped crane the mud of mummification is delivered to the tipper outward transport together with slag layer; After micropore filter block layer stops up, open the backwash of back flushing equipment and cut dirt in slag layer and cleaning, guarantee that filter material layer is in good working order.
Being provided with of sludge drying bed is as depicted in figs. 1 and 2, and sludge drying bed 1 is equipped with water distributing pipe 3, micropore filter block layer 9 and slag layer 10 from bottom to up, and the thickness of micropore filter block layer 9 is 0.1～0.5m, filter opening≤1mm; The thickness of slag layer 10 is 0.1～0.15m, and water distributing pipe 3 is connected with pumping and filtering device 4, and pumping and filtering device 4 connects rising pipe 5; The other end of water distributing pipe 3 is connected with back flushing equipment 6; Micropore filter block layer 9 is installed on the filtering layer support 11, and establishes fender bracket 12 on micropore filter block layer 9 top, is provided with into mud pipe 2 in the upper end of the enclosure wall 8 of sludge drying bed 1; Sludge drying bed 1 is divided into plural zone, and sludge drying bed 1 is equipped with clamshell-equipped crane 7.
The working process of the utility model is following:
Mud gets into sludge drying beds 1 through advancing mud pipe 2, opens pumping and filtering device 4, exhaust the infiltration of water distributing pipe 3 places after; Form negative pressure in sludge drying bed 1 bottom; Impel the moisture in the mud successively to pass through slag layer 10, micropore filter block layer 9, drainage is connected to the sewage equalizing tank through water distributing pipe 3 by rising pipe 5, and the mud of mummification dams and in slag layer 10, through clamshell-equipped crane 7 mud delivered to the tipper outward transport; Slag layer upgraded before next work period, so repeatedly circulation.In addition, after micropore filter block layer 9 stopped up gradually, mud diafiltration resistance increased as time passes, at this moment opened 6 backwashes of back flushing equipment and cut dirty in slag layer 10 and cleaning.
