The multilayer bevel-plate sedimentation device is excellent in draining effect, is capable of smoothly disposing spoil and avoiding blocking and is high in adaptability for various water qualities of surface water. A draining effect is below 2NTU. The multilayer bevel-plate sedimentation device is suitable for the field of water treatment.
Description
Technical field
The present invention relates to water-treatment technology field, exactly is that a kind of multilayer becomes the spacing unsteady flow to sloping plate deposition equipment.
Background technology
At present; In water treatment field, swash plate (or inclined tube) sedimentation basin is used comparatively extensive, and they all are based on shallow pool theory and grow up; This theory is thought: under the certain condition of sedimentation basin dischargeable capacity; Reduce the swash plate spacing, just shortened the deposition distance and increased desilting area, the removal efficient of particle is improved.But in actual moving process, usually have some problems, small floccule body particulate leaks from the swash plate top with current easily, and this mainly is because the effect of inertia of buoyancy of water and small floccule body particle causes.When the swash plate spacing hour, deposition efficiency just improves, and still, when raw water turbidity is higher, just causes swash plate (inclined tube) to stop up easily.So developing the settling apparatus that can solve these two problems simultaneously is big technical barriers that face at present.
Summary of the invention
The objective of the invention is provides a kind of multilayer to become the spacing unsteady flow to sloping plate deposition equipment to top technical barrier, can guarantee that the small floccule body particle in swash plate top does not leak and spoil disposal is unobstructed.
The present invention adopts following technical scheme to realize the present invention:
The present invention forms by becoming the spacing type sloping plate component more than 3 layers or 3 layers, closely arranges between layer and the layer, and bottom type sloping plate component spacing is maximum, and middle level type sloping plate component spacing reduces from the bottom to top successively, and upper strata type sloping plate component spacing is minimum.Each layer type sloping plate component and horizontal plane angle all are 60 degree, and adjacent two layers type sloping plate component arranged direction is opposite, so current from bottom to top successively change.Each layer type sloping plate component height is identical, and its scope is 300---500mm.
The invention has the beneficial effects as follows:
The present invention is strong to all kinds of water quality adaptability, and the small floccule body particle in swash plate top does not leak, and deposition efficiency is high, and the water outlet effect can reach below the 2NTU, and spoil disposal is unobstructed does not stop up.

In the accompanying drawing, 1 bottom type sloping plate component, 2 middle level type sloping plate components, 3 upper strata type sloping plate components, 4 water legs, 5 water distribution tracery walls, 6 discharge pipelines, 7 mud-removing buckets.
The specific embodiment
Shown in accompanying drawing; The utility model is formed by becoming the spacing type sloping plate component more than 3 layers or 3 layers; Bottom type sloping plate component spacing is maximum, and middle level type sloping plate component spacing reduces from the bottom to top successively, and upper strata type sloping plate component spacing is minimum; Each layer type sloping plate component and horizontal plane angle all are 60 degree, and adjacent two layers type sloping plate component arranged direction is opposite.Current are from bottom to top successively through each layer type sloping plate component, and constantly change flows to.Current floccule body granule density in the bottom swash plate can form more greatly has active slime layer, when the floccule body particle can be trapped through the contact flocculation effect during through this layer.Big floccule body particle will be removed in bottom and middle level type sloping plate component, flows to because current from bottom to top constantly change through the swash plate district, and small floccule body particle will depart from streamline and held back by swash plate under effect of inertia.The swash plate spacing successively reduces, and effectively desilting area successively increases, and floccule body concentration vertically from bottom to top reduces gradually, thereby has given full play to the crown_interception of each layer type sloping plate component.
In conjunction with accompanying drawing the utility model is done and to be further described: get into inclined-plate clarifying basins through the water of the flocculation basin water distribution tracery wall 5 through changeover portion; The flow direction of water is served as reasons down supreme; Floccule body glides at bottom type sloping plate component 1 surface precipitation and along the swash plate surface; Under the jacking effect on the current direction, and move upward, repeat precipitation process with current; Carrying out complicated physics chemical action between the floccule body particle, so just below bottom swash plate district and bottom type sloping plate component 1, forming the dense slime layer of one deck in one section zone with activity.Follow-uply come the floccule body in the water to form the more floccule body of large scale, be lowered into mud-removing bucket 7, can carry out regular spoil disposal according to practical operating experiences in the effect of gravity through this active sludge layer.Under sloping plate deposition and active sludge layer contact flocculation double action, be trapped through the most of floccule body particle in the water of bottom type sloping plate component 1 entering middle level type sloping plate component 2, the floccule body particle that is not trapped as yet has been some small floccule body particles.When current during through middle level type sloping plate component 2, because water (flow) direction constantly changes, small floccule body particle constantly departs from streamline, and type sloping plate component from the bottom to top spacing constantly dwindling, make small floccule body particle be easy to just be trapped.Upper strata type sloping plate component 3 has further dwindled spacing, mainly plays security personnel's effect, and behind the type sloping plate component of upper strata, current continue to rise, and conflux into water leg 4, water outlet then.
According to the utility model that above-mentioned principle is invented, deposition efficiency can improve more than 80%, and effluent quality guarantees below 2NTU, and do not stop up.
