Abstract
The invention specifically relates to an upgrading and transforming method special for a sewage biological treatment facility, belonging to the technical field of sewage biological treatment in the environmental engineering discipline. In order to improve the comprehensive treatment efficacy of the existing sewage biological treatment structures, during the technical transformation of a pushing-flow biological treatment structure with a traditional activated sludge method as the representative, according to the invention, a single aerobic running mode of original biological treatment systems is transformed into a composite anoxic-aerobic alternating running mode through a plurality of technical measures on the basis of the original process without changing large-size structures, thus realizing the maximal efficacy of a composite biological treatment structure. The upgrading and transforming method for the sewage biological treatment facility provided by the invention has the characteristics of simple and feasible process, low cost and prominent effect.
Description
Technical field
The invention belongs to technical field of sewage in the environmental engineering subject, be specifically related to a kind of upgrading method for sewage biological treatment facility.
Background technology
Current, along with improving constantly of sewage disposal technology level, in order to adapt to increasingly strict sewage discharge requirement, further improve the treatment efficiency of municipal sewage plant, many built sewage works are in the urgent need to carrying out the technology upgrading transformation, and begun to carry out the trial that various upgrade techniques are transformed, but how according to own characteristic, select rational technical scheme to become the key of implementing upgrading.In built municipal sewage plant, what mostly adopt is the activated sludge process Sewage treatment systems, therefore, the emphasis that sewage work's technology upgrading is transformed, should be for built activated sludge process Sewage treatment systems, and major objective is fully to remove in the sewage under the organism condition satisfying, and makes the Sewage treatment systems behind the upgrading have higher biological carbon and phosphorous removal ability.
Summary of the invention
The present invention mainly is based on above-mentioned technical background, take a series of experimental study as the basis, for built activated sludge process Sewage treatment systems, for rationally reducing the investment cost of technological transformation, the maximum efficiency of performance biological treatment structures, aerobic-anoxic and pulsation inertial effect according to biological sewage treatment are theoretical, when proposition undergoes technological transformation for the biological treatment of the pulling flow type take traditional activated sludge process as representative structures, on original technique basis with do not change under the condition of large-scale structures, for enhanced sewage factory and office reason ability, should make the aeration tank of main biological treatment structures, can move with alternative expression Anoxic/Aerobic active sludge mode and combined type Anoxic/Aerobic active sludge mode.
To achieve these goals, the present invention takes following technological step:
The one, can move in alternative expression Anoxic/Aerobic active sludge mode in order to realize original biological treatment system, should make the aeration intensity of the mounted aerating apparatus of front end of former aeration tank controlled, namely can the decrement aeration, then at the front end of aeration tank the underwater turbine whipping appts is installed, stir and aeration agitation intensity by adjusting submarine mechanical, original aeration tank was moved by aerobic mode by the past, both changed into and can also can move by Hypoxic types even aerobic mode by the anaerobism mode, realized as required Anoxic/Aerobic alternate run purpose thereby reach.
The 2nd, in order further to improve biological denitrificaion efficient, suspension-type combined filler in the certain area of original aeration tank structures, its mode is along aeration tank length two ends under at the bottom of the pond and pond reinforcing bar to be installed, then hang the soft filler of getting one's things ready, this filler can spread out with the bottom-up bar shaped scattering dress that is in the pond of the increase of aeration rate when aeration, be evenly distributed in the pond, biology aeration tank in the set growth long for generation time creates conditions, thereby can make this system can improve the biological denitrificaion ability again on the reinforced phosphor-removing basis.
Positively effect of the present invention is:
For the pulling flow type biological treatment system take traditional activated sludge process as representative, adopt this array mode, not only can make original single aerobic operation scheme, be adjusted into the aerobic alternate run of anaerobic/anoxic, and by improving the organism and the contact strength that is suspended on the microbe from adhering of growing on the filler in the sewage, the comprehensive effectiveness that enhancing sewage biological is processed improves the efficient of sewage disposal, improves the composite water quality of water outlet.
Embodiment
When the pulling flow type biological treatment structures take traditional activated sludge process as representative undergo technological transformation as example:
1, in 1/3rd or 1/4th sections the gallery scope that former aeration tank head end begins, the underwater turbine whipping appts suitably is installed, and make the aeration intensity of original aerating apparatus controlled, namely can the decrement aeration, then stir and aeration agitation intensity by adjusting submarine mechanical, this section zone can both can also can be moved by Hypoxic types by the anaerobism mode.
2, in the gallery scope of remaining 2/3rds sections or 3/4ths sections of former aeration tank, along aeration tank length two ends under at the bottom of the pond and pond reinforcing bar is installed, is then hung the soft filler of getting one's things ready, the length of every section hanging filler and the width of this gallery, highly identical.
3, in the gallery scope of remaining 2/3rds sections or 3/4ths sections of former aeration tank during suspension-type combined filler, also can be along the aeration tank gallery every one section hanging filler, every one section hanging filler not, the length of every section hanging filler and the width of this gallery, highly identical, every section not hanging filler length also with the width of this gallery, highly identical, and alternately go forward side by side along the gallery of former aeration tank by the current working direction.
Claims (1)
1. sewage biological treatment facility upgrading method, it is characterized in that: when the biological treatment of the pulling flow type take traditional activated sludge process as representative structures are undergone technological transformation, in 1/3rd or 1/4th sections the gallery scope that former aeration tank head end begins, the underwater turbine whipping appts is installed, make the aeration intensity of original aerating apparatus controlled, can carry out the decrement aeration, then stir and aeration agitation intensity by adjusting submarine mechanical, this section zone is moved by Hypoxic types; Simultaneously in the gallery scope of remaining 2/3rds sections or 3/4ths sections of former aeration tank, the long soft filler of pencil that hangs along the aeration tank, make original aeration tank by moving by single aerobic mode in the past thereby reach, change the purpose with the operation of Anoxic/Aerobic over-over mode into.
