The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure, this roll immersed membrane capillary sludge deep dehydrator, the casing 1 that comprises a sealing, casing 1 has removable cover 1.1, sidewall bottom at casing 1 is provided with spoil disposal door 1.2, on the upper surface of casing 1 base plate, be provided with bracing frame 2, on bracing frame 2, be provided with filtering bodies 3, on the casing below the filtering bodies 31, be provided with outlet pipe 4, on filtering bodies 3, be provided with membrane capillary filter 5, be positioned on the casing 1 of membrane capillary filter 5 tops and offer compressed air intake interface 6, described membrane capillary filter 5 comprises support cylindrical shell 5.1 and tubular filter cloth 5.2, the tube closedtop that supports cylindrical shell 5.1 closes, the tube end of supporting cylindrical shell 5.1 is a filter screen 5.5, tubular filter cloth 5.2 is installed in the endoporus that supports cylindrical shell 5.1, offers lautertuns 5.3 on the described support cylindrical shell 5.1, is positioned at lautertuns 5.3 width of rebate that support on cylindrical shell 5.1 outside wall surface less than being positioned at lautertuns 5.3 width of rebate that support on cylindrical shell 5.1 internal faces.
The section of described lautertuns 5.3 is a wedge shape.Described lautertuns 5.3 is the straight trough shape, and the length direction of lautertuns 5.3 is set in parallel with the axis that supports cylindrical shell 5.1.
In the endoporus of tubular filter cloth 5.2, be plugged with backwash water inlet pipe 5.4.
The bottom edge of described spoil disposal door 1.2 is concordant with the upper surface of filtering bodies 3.
Casing 1 can adopt common iron, cement manufacturing, and casing 1 is 2 meters wide, 4 meters long, high 1.5 meters cuboids.The plate upper surface of casing 1 has metal supporting frames 2, the auxilliary filtering bodies 3 of establishing above the metal supporting frames 2, filtering bodies 3 is selected micropore sand filtration brick for use, sand filtration brick smooth surface, inside is sand grains structure (2008 Olympic Games ground infiltration brick), and the removable cover 1.1 of casing 1 is can be portable, connects the thickly dotted membrane capillary filter 5 that is evenly distributed on the cover plate, casing 1 top is equipped with compressed air intake interface 6, and there is the backwash water pipe of series connection on removable cover 1.1 surfaces.
During use, at first reach about 80% filling mud in the casing 1, on filtering bodies 3, insert membrane capillary filter 5 then, when inserting membrane capillary filter 5, a Geometric drawing-board is arranged above the mud, as long as it is promptly passable on the filtering bodies 3 that membrane capillary filter 5 is inserted into the bottom, membrane capillary filter 5 is combined into a unit by supporting cylindrical shell 5.1 with tubular filter cloth 5.2; Support cylindrical shell 5.1 usefulness common stainless steel pipes and be processed into 25 centimeters high, 5 centimeters diameters, two sections are threaded, can many screen pipes that connect into all size length, support the lautertuns 5.3 that processes wedge shape on cylindrical shell 5.1 wall bodies, big mouthful of lautertuns 5.3 interior, 10～15 mm wides, the tip of lautertuns 5.3 outside, the tip width of lautertuns 5.3 is 1.0～1.5 microns, the big mouthful of ratio with the width of osculum is about 100: 1, the tip of lautertuns 5.3 is opened 1 with laser and is left, must shape colloidal substance build bridge in the cohesion of the tip of lautertuns 5.3, as the 5 preliminary treatment effects of membrane capillary filter, big mouthful of lautertuns 5.3 be convenient to backwash interior; Triangle stainless steel strength ratio is higher, when inserting mud, play the effect of diaphragm capillary filtering device 5, support the top of cylindrical shell 5.1 and leave backwash attachment plug, with cleaning water pipe UNICOM, the bottom is a planar structure, and the tube end filter screen 5.5 that supports cylindrical shell 5.1 is 400 order wire nettings, when inserting mud, the bottom surface of supporting cylindrical shell 5.1 with filtering bodies 3 contacts promptly can, do not need to fix; The installing space of membrane capillary filter 5 is that adjacent two support cylindrical shells, 5.1 outer walls are at a distance of about 10 centimeters.
The backwash water pipes are installed above the removable cover 1.1, during sludge dewatering need not, finish the back backwash in desliming and use; Membrane capillary filter 5 inserts after the casing 1 interior mud, the joint of the backwash water pipe 7 on the removable cover 1.1 inserts the backwash water inlet pipe 5.4 on membrane capillary filter 5 tops, cover removable cover 1.1, removable cover 1.1 seals with opening bolting soon with casing 1 structure, start compressed air, pressure is controlled at 0.1～0.15mpa/cm
2Pressure, continuous operation 20 minutes stopped 10 minutes, continued pressurized operation 20 minutes, went round and began again, sludge dewatering in 3～5 hours finishes (analyze sludge moisture content and fixed control with difference gauge), moisture percentage in sewage sludge reaches about 50%.Unclamp bolt then, lift by crane out removable cover 1.1, extract membrane capillary filter 5, the spoil disposal door 1.2 of opening casing 1 one ends carries out spoil disposal, removable cover 1.1 on the clean bonnet of mud discharging, isolated clean water adopts high-order normal pressure backwash, 3～5 minutes backwash time, mainly the filtering bodies 3 of bottom half is carried out backwash in the normal pressure backwash process; Membrane capillary filter 5 then concentrates on and carries out the normal pressure backwash in the backwash device, and the backwash time is 3～5 minutes, and the sewage after the cleaning enters the wastewater sedimentation groove, works and adopts special film washing liquid bubble to wash in 3～5 days 10 minutes.
The mud expressed water is owing to be to adopt rolling MBR submerged membrane, membrane aperture is dense, reach about 0.2～0.4 micron, therefore reach no bacterium basically, just contain organic matters (COD) less than materials such as 30 milligrams/L, toxic material, heavy metal, phosphorus (BOD) and ammonia, nitrogen, soft metals, can reach country, secondary A B grade standard discharging, water reuse in obtaining if desired, need only handle the standard of water reuse in promptly can reaching by series connection one-level MBR submerged membrane or mesopore tunica fibrosa.Pay special attention to this device and also must thoroughly clean once with the film washing liquid body about one week of use, the tubular filter cloth 5.2 among the present invention possesses the base-material that contains hydrophilic functional groups, so permeability rate is 3～5 times of the normal film filtering material.
After-treatment system also can adopt the Blang's version solid-liquid separator [patent of invention 200710019525.X] and the micro-aerated biological filter [patent of invention 200910031138.7] that have obtained patent of invention to handle directly qualified discharge of later waste water, perhaps middle water reuse.
