Abstract
This invention discloses a technique for garbage buried treatment with denitrification in site. In a nitration reactor, there are: an upper layer-aeration zone having aerator, a medium layer-facultative zone and the bottom layer-anaerobic zone. In the aeration zone, ammonia is oxidized into NO3-by the autotrophic nitrifier; in the facultative zone, NO3-is reduced into N2 by denitrifying bacteria by using organic substances as electron donor, and the N2 is released into the air to achieve the transformation from NH4 to N2 and its removal. In the anaerobic zone, the organic matter is degraded into methane. This invention provides a biological reactor by using above-mentioned technique. In this invention, the three (buried main body, produced gas and liquid) is considered into an integral one, so having advantages of: low cost, high efficiency.
Description
Technical field
The present invention relates to a kind of consumer waste filling and embedding treatment technology, be meant a kind of consumer waste filling and embedding treatment technology and bio-reactor specifically with in-situ denitrification function.
Background technology
Percolate directly recharges the type bioreactor landfill owing to anaerobic environment and circulation summation, and ammonia nitrogen concentration causes the deterioration of the ecological environment in the landfill yard far above traditional sanitary filling field in the percolate, delays landfill yard stabilization process.Yet at present removing of ammonia nitrogen generally adopted materialization treatment process and biological treatment outside the venue in the percolate, investment construction expense height, and have environmental risk, so be not suitable for promoting the use of.Adopt the design not only to solve the biological in-situ denitrification functions, realize the rapid stabilization of domestic refuse, and maximum constraints is avoided the secondary pollution problem of landfill yard.
Application for a patent for invention 200410088806.7 discloses a kind of integrated bioreactor for the treatment of refuse percolate, is made up of two bio-reaction zones and a regulatory region, and equal filled biomass filler forms aerobic zone and anaerobic zone in each bio-reaction zone.In aerobic zone, organism is degraded to inorganic carbon by aerobic heterotrophic bacterium, and the nitrifying process of control ammonia nitrogen is in the nitrosification stage, and the ammonia nitrogen with 50% is oxidized to nitrite, and the water outlet of aerobic zone enters anaerobic zone after mixing with the pH regulator agent in regulatory region.At anaerobic zone, anaerobic ammonia oxidizing bacteria is electron donor reduction nitrite with the ammonia nitrogen, is that electron acceptor(EA) comes the oxidation ammonia nitrogen with the nitrite, changes ammonia nitrogen and nitrite nitrogen into nitrogen, and other anaerobion of partial organic substances shellfish absorbs or degraded.This technical scheme is to carry out liquid treatment at percolate separately, and garbage loading embeading main body and percolate are separately considered, invests the working cost height like this.
Summary of the invention
The invention provides a kind of too high outstanding problem of ammonia nitrogen concentration in the solution percolate that is, realize the consumer waste filling and embedding treatment technology of biological decarburization and biological in-situ denitrification functions combination.
A kind of consumer waste filling and embedding treatment technology with in-situ denitrification function, may further comprise the steps: in nitrator, realize the upper strata aeration, form aerobic, the middle anoxic in upper strata, lower floor's anaerobic environment, at aerobic zone, ammonia is oxidized to NO with it under the effect of autotrophic type nitrobacteria
3 -, in the oxygen-starved area, by denitrifying bacterium with organism as electron donor, make NO
3 -Be reduced to N
2And from liquid phase, discharge, realize NH
4 +The conversion of-N and removal at anaerobic zone, realize organic degraded product methane.
The present invention also provides a kind of bio-reactor based on above-mentioned treatment technology.
A kind of consumer waste filling and embedding bio-reactor with in-situ denitrification function, be followed successively by new refuse landfill yard, methane-producing reactor and nitrator by three reactor and be communicated with the recycle system of forming by the bottom percolate water outlet of previous stage reactor and the top percolate water-in of back A reactor, be equipped with waste compartment and air chamber in each stage reactor, nitrator waste compartment upper strata is provided with the aeration layer, is followed successively by aerobic zone, oxygen-starved area and anaerobic zone in the nitrator waste compartment from top to bottom.
The bottom percolate water outlet of described methane-producing reactor is communicated with through the top of a triphase separator and nitrator percolate water-in, the gas phase path access set airbag of triphase separator.
Be provided with some effusers in the described methane-producing reactor, effuser access set airbag.
Be equipped with collection bottle and intake pump on the percolate circulation duct between described each stage reactor and the next stage reactor.
Described each stage reactor waste compartment bottom is lined with metalling, so that percolate flows out.
Described each stage reactor waste compartment top is provided with sand bed.
The present invention considers garbage loading embeading main body, landfill gas and percolate as an organic whole, on the nitrator upper strata aeration layer is set, make and form aerobic, a middle anoxic in upper strata, lower floor's anaerobic environment in the nitrator, realized at the inner biological in-situ denitrification functions of bioreactor landfill, need not to handle outside the venue at percolate separately, the investment working cost is low, the processing efficiency height.
