Background technology
At present, municipal sewage treatment in the world more than 90% adopts activated sludge method, but result can produce a large amount of water ratio up to more than 99% excess sludge, volume account for process the water yield 0.3% ~ 0.5%, can 0.5 to 1.0 times be increased according to advanced treatment sludge quantity.The built scheme erecting recovery and reuse residual active sludge in various countries, common method is landfill or imposes in soil as nutritive element, but these methods can cause the secondary pollution of environment.So new legal provisions forbid abandoning of biosolids and landfill, mud has to pass through minimizing, stabilization, harmless treatment, encourages to realize resource utilization.
Sludge dewatering is a kind of method the most economic in sludge reduction, it is an important step in sludge treatment technique, its objective is the water ratio removing pore water in mud and capillary water, reduction mud, as the mud of water ratio 98%, reduce by the water of 2%, sludge volume will reduce 50%, sludge dewatering reduces sludge volume, be convenient to transport and process, or reduce space, reduce drying sludge and the necessary means of energy required for burning, for the ultimate disposal of mud creates conditions.
Containing the zoogloea that wetting ability negative electricity biomone is formed in mud, zoogloea makes mud not easily dewater, through mechanical treatment water ratio still more than 80%.In order to improve the utilising efficiency of excess sludge, sludge pre-treatment techniques more and more comes into one's own, the more sludge pre-treatment techniques of current research mainly comprises mechanical process, excusing from death ripple method, Grape berry method, microwave method, cold method, radiation method, By Ozone, chlorine method and acid-base method etc., but all there is respective shortcoming in these technology, as: require higher to equipment and materials, operation and maintenance cost is high.In addition, part preconditioning technique can increase secondary pollution and subsequent technique intractability.
Summary of the invention
The purpose of this utility model is for the zoogloea containing the formation of wetting ability negative electricity biomone in mud; the characteristic that zoogloea makes mud not easily dewater; a kind of mud granule gasifying device is provided; collided by variable speed controlled step by step; active sludge homogenizing is made to become the mud granule that irreducible water ratio is less; mechanical dehydration degree is higher, can avoid the use of a large amount of flocculation agent or amendment in dehydration.
The technical scheme taked for achieving the above object is: a kind of mud granule gasifying device, relate to stirring mechanism, stirring mechanism comprises low rate mixing mechanism and rapid stirring mechanism, framework loads rapid stirring mechanism and low rate mixing mechanism, and rapid stirring mechanism is communicated with sludge inlet and flocculation agent entrance; Low rate mixing mechanism comprises interior survey isometric helix and outside Unequal distance cone-type spiral, interior survey isometric helix and outside Unequal distance cone-type spiral concentric co-axial, be arranged in a conical shell, low rate mixing mechanism connects drive-motor by stir shaft, drive-motor is arranged on crossbeam, crossbeam both sides welding longitudinal motion guide rail, crossbeam is with contact therewith but be not fixedly connected with, crossbeam is connected with Linear actuator and along guide rail longitudinal motion, Linear actuator is fixed on the inner side that on framework and installation site is framework and guide rail contact; Rapid stirring mechanism outlet low rate mixing actuator base entrance, low rate mixing mechanism top offers sludge outlet.
The drive-motor parameter of described low rate mixing mechanism: maximum revolution: 425 rpm; Run revolution: 900-1400 rpm.
The drive-motor parameter of described rapid stirring mechanism: maximum revolution: 1425 rpm; Run revolution: 200-330 rpm.
The drive-motor of described low rate mixing mechanism and crossbeam are by Flange joint, and drive-motor drives and connects stir shaft and do vertical movement by a small margin by Linear actuator with crossbeam.
The utility model framework is the basi components of complete machine, carries the weight of each parts, and itself and each component contact are more, basic assembled portion as a whole during assembling.Crossbeam: the horizontal brace of granulating device.Linear actuator: the lifting power plant of new mixture bar.Flocculation agent injected system: required flocculation agent adds point and utility appliance device.
The utility model is compared with the mud granule gasifying device of this area, there is outstanding feature: according to sludge character difference, adopt a kind of stable, efficiently fast and at a slow speed granulating integrated technique, realize two kinds of stirring techniques, but do not need two stirred pots, volume is little, technique is continuous, wherein new mixture bar major function forms granule sludge at a slow speed, it is a kind of taper whipping appts, be made up of interior survey isometric helix device and outside Unequal distance cone-type spiral device, two screw concentric co-axial, different radii causes centrifugal force different along axle distribution with fluidised form, mud moves to cone top from bottom, because radius reduces gradually, centrifugal force and shearing force also reduce gradually, the cancellated destruction of flocculence is accelerated in the high strength mixing of large radius, when stirring intensity reduces along axle, sludge flocculation structure is through discrete, collision and restructuring, form stable particle.Mud is after the process of this device, and after outlet settling of granular sludge, water ratio can be down to 85 ~ 90%.
The utility model device makes the quick adhesion of mud and forms the good granule sludge of hydrophobicity gradually, realizes granular sludge pre-treatment, improves granulating efficiency and reduces energy consumption.The pretreatment process of granular sludge, enhances system dehydrating effect, improves dewatering efficiency, reduces the usage quantity of flocculation agent.
