Abstract
The invention relates to a method of combining biological film and aquatic earthworm to treat sewage and sludge, the sewage treatment aeration biochemical pond is filled with fillings as biological carrier, the microorganism is inoculated and domesticated on the surface of the biological carrier to form a biological film, the aquatic earthworm is cultivated on the surface of the formed biological film, the aquatic earthworm on the surface of the formed biological film digests the aged biological film and sludge, after the aquatic earthworm dies, the dejecta renews to be decomposed by the microorganism so as to form <aquatic earthworm-microorganism> biological chain, thereby purifying sewage and sludge. The invention purifies sewage water and sludge at the max intent, thereby ensuring high efficiency operation of sewage treatment system. The invention is simple and can perform the improvement of the prior biological film treatment sewage process. The invention has the advantages of low investment cost and high efficiency.
Description
Technical field
The invention belongs to the sewage disposal field of environmental engineering, be specifically related to a kind of method that adopts microbial film and Limnodrilus hoffmeisteri combination treatment sewage, mud.
Background technology
In sewage disposal, generally all adopt biochemical treatment, biochemical treatment is purified waste water simultaneously, because the metabolism of microorganism can produce a large amount of excess sludges, need be for further processing, and cost is higher secondary pollution easily, how reducing sewage biochemical treatment sludge output and dispose excess sludge, is great difficult problem of water treatment field; The less biomembrance process of sludge output significantly reduces with respect to the traditional technology sludge output at present, but also is confined to single disposing of sewage, and can not finally solve the mud problem.
Summary of the invention
Purpose of the present invention is introduced Limnodrilus hoffmeisteri and is handled mud on the prior biological embrane method is disposed of sewage the basis, creates biologic chain, improves sewage treating efficiency, solves excess sludge, saves running cost.Technical scheme of the present invention is so to realize:
The method of a kind of microbial film and Limnodrilus hoffmeisteri combination treatment sewage, mud, in the aeration in sewage treatment biochemistry pool, install filler additional as bio-carrier, at bio-carrier surface seeding, acclimated microorganism, form microbial film, biofilm surface is cultivated Limnodrilus hoffmeisteri, aging microbial film, the mud that comes off of Limnodrilus hoffmeisteri digestion on the biofilm surface, after the described Limnodrilus hoffmeisteri death and ight soil again by microbiological degradation, promptly form " Limnodrilus hoffmeisteri---microorganism " biologic chain, purify waste water and mud.
The present invention has mainly overcome existing single the disposing of sewage of sewage biochemical treatment microorganism and can not handle the limitation of mud, introduce the unicellular lower eukaryote Limnodrilus hoffmeisteri, promptly cultivate Limnodrilus hoffmeisteri at the biofilm surface that forms, 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 treatment tank form biologic chain, maximization is purified waste water and mud, guarantees the high-efficiency operation of Sewage treatment systems.Limnodrilus hoffmeisteri main effect in this biosystem is to be used for purifying mud, and it can carry out self-reproduction, reaches trim point.
The inventive method is simple, can improve prior biological film sewage treatment, and it is low to have cost of investment, and characteristics such as operational efficiency height have popularizing application prospect.
Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
Embodiment: in the aeration in sewage treatment biochemistry pool, install filler (as elastic filler) additional as bio-carrier, at the bio-carrier surface seeding, acclimated microorganism, form microbial film, cultivate Limnodrilus hoffmeisteri at the biofilm surface that forms, during system works, microorganism panning sewage pollution thing on the microbial film, purify waste water, the microbial film that Limnodrilus hoffmeisteri digestion on biofilm surface comes off, mud, after the Limnodrilus hoffmeisteri death and ight soil again by microbiological degradation, thereby form " sewage; Limnodrilus hoffmeisteri corpse; pollutents such as earthworm excrement---microbiological degradation---microbial death---Limnodrilus hoffmeisteri---Limnodrilus hoffmeisteri corpse; pollutents such as earthworm excrement " rational biologic chain, purify waste water thereby reach maximization, the effect of mud.Limnodrilus hoffmeisteri mainly is to be used for purifying mud in this biosystem, and it can carry out self-reproduction, reaches trim point.
Claims (1)
1. the method for microbial film and Limnodrilus hoffmeisteri combination treatment sewage, mud, in the aeration in sewage treatment biochemistry pool, install filler additional as bio-carrier, at bio-carrier surface seeding, acclimated microorganism, form microbial film, it is characterized in that cultivating Limnodrilus hoffmeisteri at the biofilm surface that forms, aging microbial film, the mud that comes off of Limnodrilus hoffmeisteri digestion on the biofilm surface, after the described Limnodrilus hoffmeisteri death and ight soil again by microbiological degradation, promptly form " Limnodrilus hoffmeisteri---microorganism " biologic chain, purify waste water and mud.
