Abstract
The utility model relates to a device using water earthworms to treat sludge. Water earthworms are raised on the biomembrane arranged in the existing sludge treatment device; the aged and deciduous biomembrane and sludge are digested by the water earthworms; the dead earthworms and dejections are re-decomposed by microbes; thereby, the microbes and earthworms in the sludge treatment pool jointly form a biological chain to purify the sludge to the largest extent, and ensure the high-efficient operation of the sludge treatment system; and the water earthworms can breed and reach a balance point. The device has the advantages of simple structure, low operation cost and high efficiency of sludge treatment.
Description
Technical field
The utility model belongs to the sludge treatment field of environmental engineering, is specifically related to a kind of device of Limnodrilus hoffmeisteri biological treatment mud.
Background technology
In sludge treatment, generally all adopt biochemical treatment, biochemical treatment purifies mud simultaneously, because the metabolism of microorganism can produce a large amount of excess sludges, need be for further processing, press filtration landfill and burning are conventional treatment processs, and cost is higher, easily secondary pollution, how disposing sludge is great difficult problem of water treatment field.
Summary of the invention
The purpose of this utility model provides a kind of device of simple in structure, efficient is high, running cost is low Limnodrilus hoffmeisteri biological treatment mud.The technical solution of the utility model is so to realize:
A kind of device of Limnodrilus hoffmeisteri biological treatment mud, comprise microbial film that mud inlet (1), bio-carrier (2), the microorganism of being located at digestion zone (7) top form on carrier, be located at aerator (3), settling region (5) sludge reflux pump (4) and water outlet (6) in the digestion zone (7), the biofilm surface of described bio-carrier (2) is cultivated Limnodrilus hoffmeisteri.
As preferably, described aerator (3) is an aerator under the compound leaf pulling flow type liquid.
As preferably, described bio-carrier (2) is soft strip.
As preferably, described bio-carrier (2) be located at aerator (2) around.
The utility model in sludge treatment equipment bio-carrier and microbial film on cultivate Limnodrilus hoffmeisteri, aging microbial film, the mud that comes off of Limnodrilus hoffmeisteri digestion, after the Limnodrilus hoffmeisteri death and ight soil again by microbiological degradation, make microorganism and Limnodrilus hoffmeisteri in the mud unite the formation biologic chain, maximization purifies mud, guarantee the high-efficiency operation of sludge treating system, Limnodrilus hoffmeisteri can carry out self-reproduction, reaches trim point.The utlity model has characteristics simple in structure, that running cost is low, sludge treatment efficient is high.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
Embodiment: with reference to the accompanying drawings, a kind of device of Limnodrilus hoffmeisteri biological treatment mud, comprise the mud inlet (1) of being located at digestion zone (7) top, microbial film that bio-carrier (2) microorganism forms on carrier, be located at the aerator (3) in the digestion zone (7), the sludge reflux pump (4) and the water outlet (6) of settling region (5), bio-carrier is soft strip, and be located at aerator (3) around, continuous aeration in the digestion zone (7), the biofilm surface of bio-carrier (2) is cultivated Limnodrilus hoffmeisteri.Aerator (3) is an aerator under the compound leaf pulling flow type liquid.
During work, mud is entered in the digestion zone (7) by mud inlet (1), be positioned at bio-carrier (2) intermediary aerator (3) continuous aeration, microorganism forms microbial film on bio-carrier, microbial film, mud that Limnodrilus hoffmeisteri digestion on biofilm surface comes off, after the Limnodrilus hoffmeisteri death and ight soil again by microbiological degradation, thereby form " pollutents such as Limnodrilus hoffmeisteri corpse, ight soil---microbiological degradation---pollutents such as mud---Limnodrilus hoffmeisteri---Limnodrilus hoffmeisteri corpse, ight soil " rational biologic chain, it can carry out self-reproduction, reaches trim point.The sedimentary a small amount of mud in settling region (5) is back in the digestion zone (7) by sludge pump (4), is discharged by water outlet (6) through the water of post precipitation.
Claims (4)
1, a kind of device of Limnodrilus hoffmeisteri biological treatment mud, comprise microbial film that mud inlet (1), bio-carrier (2), the microorganism of being located at digestion zone (7) top form on carrier, be located at aerator (3), settling region (5) sludge reflux pump (4) and water outlet (6) in the digestion zone (7), the biofilm surface that it is characterized in that described bio-carrier (2) is cultivated Limnodrilus hoffmeisteri.
2, the device of a kind of Limnodrilus hoffmeisteri biological treatment mud according to claim 1 is characterized in that described aerator (3) is aerator under the compound leaf pulling flow type liquid.
3, the device of a kind of Limnodrilus hoffmeisteri biological treatment mud according to claim 1 is characterized in that described bio-carrier (2) is soft strip.
4, the device of a kind of Limnodrilus hoffmeisteri biological treatment mud according to claim 1 and 2, it is characterized in that described bio-carrier (2) be located at aerator (2) around.
