Wherein, water inlet and water distribution unit bit in reactor bottom utilizes the fixed a set of or multiunit awl group of awl group mount in the vertical orientation of reactor, and the backward flow is got the liquid mouth and is lain in packing layer lower part suspension sludge blanket, and have flocculation's material and phegma that flocculation charge device added get into the reactor behind pipe -line blending. The beneficial effects of the utility model are that: the little flco mud and free little biological particle ization of superposed layer can be promoted in succession, the reactor activated sludge volume is improved.

Description

A kind of cone group promotes the anaerobic reactor of granular sludge

Technical field

This utility model relates to field of environment engineering, particularly relates to a kind of cone group and promotes the anaerobic reactor of granular sludge。

Background technology

In traditional up-flow anaerobic reactor; the hydraulic action produced due to bottom water inlet is limited; granule sludge district and suspended sludge area can be divided in reactor; many little flcos and scattered microorganism are arranged at top, suspended sludge area; owing to sludge retention device capability is limited; these little flcos and dispersion microorganism are run off, and granular sludge is the important means alleviating this phenomenon。Granulating refers to that the microorganism in biological treatment is under suitable environmental condition, is mutually gathered into that a kind of density is relatively big, volume is relatively big, activity microbial aggregate preferably。Therefore, the existence of granule sludge can keep high sludge concentration, improves volumetric loading and the impact resistance of system。

The formation of granule sludge needs the transmission of momentum and quality, and wherein momentum is mainly provided by the hydraulic action in reactor, it is possible to promotes the quality transmission between mud, the contact-impact probability between mud namely can be made to increase, and assemble。At present, in anaerobic reactor, hydraulic action is provided by upflow velocity of intaking, and the rising of upflow velocity makes mud utilization rate increase, and the structure of granule sludge is more closely knit, particle diameter is less, biological activity is better, but mud producing erosion damage effect, the number of dropouts of mud is greatly increased。

Summary of the invention

For providing suitable hydraulic action to promote granular sludge, this utility model provides a kind of cone group to promote the anaerobic reactor of granular sludge。

Technical solutions of the utility model are as follows: a kind of cone group promotes the anaerobic reactor of granular sludge, including water inlet, water-distributing device; reaction zone, one or more cone groups and cone group fixed mount, filler and filler fixed mount; settling zone; outlet, air vent, reflux liquid taking port; backflow liquid inlet; flocculation chemicals dosing plant, pump, valve。Wherein, water inlet and water-distributing device are positioned at reactor bottom, the vertical direction of reactor utilize cone group fixed mount fix one or more groups cone group, backflow liquid taking port is positioned at packing layer bottom suspended sludge layer, and what flocculation chemicals dosing plant added has the material of flocculation and backflow to enter reactor after pipe-line blending。

Each cone group is by concentric and parallel, and adjacent spacing is the cone bucket composition of 100-200mm, and outermost layer cone bucket is 100-200mm with wall of reactor minimum spacing。

When there being multiple backflow liquid inlet on reactor differing heights, the liquid measure that passes back into of each backflow liquid inlet can be different, and to flow back into reactor from tangential direction, form level rotary flow in reactor。

The material having flocculation can be inorganic salts flocculant, natural or synthesis organic polymer flocculant, microbial flocculant, one or more of activated sludge。

The beneficial effects of the utility model are in that: the little floc sludge of superposed layer and dispersion microorganism are refluxed, and assemble under the material effect having flocculation；Tangent line flows back into the eddy flow that water produces makes the waterpower mixing condition in reactor strengthen, and enables loose sludge structure to be compressed on the conical surface, consolidation, has promoted superposed layer granular sludge；Little floc sludge and the free microorganism granulating of superposed layer can be promoted continuously, improve active mud content in reactor。

Detailed description of the invention

Below in conjunction with accompanying drawing and example, the invention will be further described, but content of the present utility model is not limited to this。

The basic thought of the present invention is; backflow is added with the material of flocculation; the gathering of the promotion little floc sludge in backflow superposed layer top and dispersion microorganism, utilizes the eddy flow of tangent line water inlet generation and the interaction of cone group to strengthen mud dimeric structure, accelerates the granulating of mud。

Example 1: adopt the device shown in accompanying drawing 1 to promote granular sludge。

In the wall of reactor 6 of reaction zone 3 correspondence, cone group fixed mount 4 and filler fixed mount 7 are installed, it is respectively used to fixed cone group 5 and filler 8, in plant running process, the suspended sludge layer of packing layer bottom is constantly refluxed pump 14 in backflow liquid taking port 12 and extracts out, reactor is entered through backflow liquid inlet 17 tangent line, eddy flow is produced in reactor, under the interaction of eddy flow and cone group 5, increase the mud flco in reactor, contact-impact between loose granule sludge and free microorganism, and flocculate further and closely knit after rolling compression on the conical surface, thus promoting granular sludge。Wherein, the capacity of returns of each height is controlled by reflux pump 14 and valve 16, thus the swirl strength controlled in reactor。For further speeding up granulating, chemicals dosing plant 13 can be set, add entrance reactor after medicament mixes with backflow to reflux line by dosing pump 15, accelerate the granulating of mud。
