Description
Technical field
The present invention relates to filler that anaerobic reactor adopts, and the decoration form of this filler.
Background technology
Adopt the anaerobic pond of filler to mainly contain anaerobic filter (AF) and fluidized-bed at present.Anaerobic filter is to be filled with various types of solid packings in reactor, wait as cobble, slag, porcelain ring, plastics and to handle organic waste water, sewage can contact with the purple microorganism that coagulates of filler top layer suspension in flow process, because on filler, not overflowing with water body, microorganic adhesion do not run off.Can obtain long sludge age down at short hydraulic detention time (HRT), its cell residence time (MRT) can reach more than 200 days.And the shortcoming one of upflow type anaerobic filter is that carrier is relatively costly, and the price of its carrier and structures building price is suitable according to estimates; It is two as suspended substance (SS) 〉=200mg/L, is short-circuited easily and stops up, and this is the reason place that AF technology can not be promoted rapidly.What fluidized-bed adopted then is inert carrier particle, shape such as gac etc., and it also will make media particle expand or fluidization, needs 0.5-10 feed liquid recirculation doubly, and this has just improved the energy consumption in the operational process.UASB then needs to adopt triphase separator, the framework costliness, and energy consumption is bigger, and it is denseer that anaerobism goes out water concentration.For the filler that adopts chemosynthesis, some Chemical Composition wherein probably suppress the breeding growth of anaerobion.
Summary of the invention
The objective of the invention is to overcome weak point of the prior art and a kind of sewage treatment capacity that can efficiently improve is provided, reduce the anaerobic reactor filler of cost of sewage disposal simultaneously significantly.
Another object of the present invention also is to provide the decoration form of a kind of this filler in anaerobic reactor.
The invention provides a kind of filler that is applicable to anaerobic reactor, it is a kind of bamboo branch, leaf.
Utilize the filler of this natural bamboo branch as anaerobic reactor, with other filler contrast more superior point is arranged: because the mao bamboon growth and breeding is very fast, it is easy to get its twig material, and cost is extremely low, can turn waste into wealth, and need not process, different in size, all can wholely use, and the bamboo branch itself contains a kind of colloid and is difficult to by microbial attack, extremely difficult rotting decomposed under anaerobic state especially, thereby needn't expend and adopt finished product bamboo big, the numerous and assorted filler that is processed into specific surface area.Because they belong to green plants, the purple haptogen shape of microbial suspension very easily adheres to again; Specific surface area is big, and it is wide to generate biomass; Because the bamboo branch becomes hollow form, therefore can be suspended in the water, fluctuate along with the generation of the biogas in the anaerobic reactor, release, thus make filling surface too much or the aged microbial film be sheared and come off.
The length of preferred bamboo branch is 1-1.5 rice.
As the bad packing of the oversize meeting of bamboo branch, be difficult for putting into the pond, go into when install in the pond and can run into pool wall, the surface-area that compares is little.If the bamboo branch is lacked very much then is caused flying away of bamboo branch easily.
The diameter of preferred bamboo branch is 1-2cm.
Preferred bamboo branch branch is many, and the end of the branch covers with the bamboo branch of the leaf of bamboo.
Such bamboo branch, light specific gravity, specific surface area is big, swims in the water easily.
The present invention also provides the method for arranging of a kind of this filler in anaerobic reactor, and this comprises the steps:
The bamboo branch filler of choosing by the water inlet position scrim of pond body put, closely put at the water outlet position, the 50%-80% that holds with the pond does not wait evenly to overlap and is placed in the body of pond, with corrosion resistant guard the intravital filler in pond is fixed in relatively-stationary mode then.
So-called relative fixed mode is meant to have certain spatial margin between guard and the packing layer, can guarantee that like this filler has certain fluctuation space, it is diffusing to avoid filler to float everywhere again, to have influenced wastewater treatment efficiency, also avoids causing the malfunctioning of all the other accessories.Owing to adopt the relative fixed mode, bamboo branch filler can be suspended in water simultaneously, fluctuate along with the biogas that produces, then the shearing force of bamboo branch and water generates causes the aging biofilm detachment of filling surface.
Described guard is the plane guard in 5 millimeters in aperture.
The plane guard that the aperture is 5 millimeters also can be used as peeler the scum silica frost that produces is cut.
Filler decoration form of the present invention further also is
Towards body edge, pond, highly branched branch tail is placed in the centre, pond to described bamboo branch filler by the end of the branch, by several layers of overlapping successively intersection, allows central elevation.
The method for arranging of filler of the present invention also comprises: earlier filler is packed with corrosion resistant bag shape screen cloth
The screen cloth of green filler with the sieve aperture shape packed it with fluffy form, screen cloth itself also can be used as peeler the scum silica frost that produces is cut.
The bag shape nylon plastic screen cloth of the preferred wide 10～15cm in hole of screen cloth.
Every bag volume is about 1M
3-1.5M
