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 at the biological sewage treatment facility.
Background technology
Current, along with improving constantly of sewage disposal technology level, in order to adapt to strict day by day sewage discharge requirement, further improve the treatment efficiency of municipal sewage plant, many sewage works that built press for and carry out the technology upgrading transformation, and begun to carry out the trial that various upgrade techniques are transformed, but, select rational technical scheme to become the key of implementing upgrading how according to own characteristic.In the municipal sewage plant that has built, what adopt mostly is the activated sludge process Sewage treatment systems, therefore, the emphasis that sewage work's technology upgrading is transformed, should be at the activated sludge process Sewage treatment systems of having built, 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, based on a series of experimental study, at the activated sludge process Sewage treatment systems of having built, for rationally reducing the investment cost of technological transformation, the maximum efficiency of performance biological treatment structures, aerobic-anoxic and pulsation inertial effect theory according to biological sewage treatment, when proposition undergoes technological transformation for the pulling flow type biological treatment structures that with the traditional activated sludge process are representative, on original technology 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 activated sludge mode and combined type anoxic aerobic activated sludge mode.
To achieve these goals, the present invention takes following technological step:
The one, can move in alternative expression anoxic aerobic activated 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, promptly can the decrement aeration, at the front end of aeration tank impeller whipping appts under water is installed then, 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, realized the aerobic alternate run purpose of anoxic as required thereby reach by the anaerobism mode by anoxic mode even aerobic mode.
The 2nd, in order further to improve biological denitrificaion efficient, suspension-type combined filler in certain zone 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, hang the soft filler of getting one's things ready then, 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 that with the traditional activated sludge process is representative, adopt this array mode, not only can make original single aerobic operation scheme, be adjusted into the aerobic alternate run of anaerobism anoxic, and by improving the organism and the contact strength that is suspended on the set microorganism that grows on the filler in the sewage, the comprehensive effectiveness that enhancing sewage biological is handled improves the efficient of sewage disposal, improves the composite water quality of water outlet.
Embodiment
The pulling flow type biological treatment structures that with the traditional activated sludge process are representative are example when undergoing technological transformation:
1, in 1/3rd or 1/4th sections the gallery scope that former aeration tank head end begins, impeller whipping appts under water suitably is installed, and make the aeration intensity of original aerating apparatus controlled, promptly can the decrement aeration, stir and aeration agitation intensity by adjusting submarine mechanical then, this section zone can both can also can be moved by the anoxic mode by the anaerobism mode.
2, in the gallery scope of remaining 2/3rds sections or 3/4ths sections of former aeration tank, reinforcing bar is installed, is 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 then along aeration tank length two ends under at the bottom of the pond and pond.
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. use characteristic of the present invention is: to being that the pulling flow type biological treatment structures of representative are when undergoing technological transformation with the traditional activated sludge process, in 1/3rd or 1/4th sections the gallery scope that former aeration tank head end begins, impeller whipping appts under water is installed, and is made the aeration intensity of original aerating apparatus controlled; In the gallery scope of remaining 2/3rds sections or 3/4ths sections of former aeration tank, the long soft filler of getting one's things ready that hangs along the aeration tank.
