Abstract
The invention discloses a preservation device of anaerobic ammonium oxidation granular sludge. The preservation device comprises a pedestal, a container body fixedly mounted on the pedestal and a gas buffer bag. The bottom of the container body is provided with a sludge discharge port. Three water outlets are arranged at one side of the container body from top to bottom. The top of the container body is respectively provided with a sludge addition port and a breather pipe. The gas buffer bag is connected with the breather pipe through a gas transmission port of the gas buffer bag. The gas buffer bag is equipped with a gas addition port. The preservation device can be used to preserve anaerobic ammonium oxidation granular sludge at room temperature for a long time, so as to alleviate decay rate of sludge activity and make it maintain high activity. Therefore, the anaerobic condition in the container can be effectively realized by the utilization of nitrogen generated during the sludge preservation period.
Description
Technical field
The present invention relates to a kind of save set of anaerobic ammonium oxidation granular sludge.
Background technology
The frequent generation of body eutrophication and increasingly high environmental quality requirement are to denitride technology, and particularly bio-denitrification technology has proposed new challenge.Than traditional nitrated-denitrification biological denitrogenation technology, advantage such as novel Anammox biological denitrification process has efficiently, low consumption and floor space are little has wide development and application prospect.Anaerobic ammonia oxidation process is based on the bio-denitrification technology of anaerobic ammonia oxidizing bacteria, and it can be that electron acceptor(EA) oxidation ammonia generates non-harmful nitrogen with the nitrite, realizes the purpose of green denitrogenation.Yet, the anaerobic ammonia oxidizing bacteria poor growth, cell yield is extremely low, though help the minimizing of excess sludge, is unfavorable for the enrichment culture of anaerobic ammonia oxidizing bacteria.Realize higher Anammox nitrogen removal performance, need abundant anaerobic ammonia oxidizing bacteria quantity, and sufficiently high anaerobic ammoxidation activity is arranged.
In the anaerobic ammonia oxidation process actual motion, often exist anaerobic ammonia oxidation reactor temporarily to throw aside and collect the phenomenon that reactor drum flows out anaerobic ammonium oxidation granular sludge.For such anaerobic ammonium oxidation granular sludge, if do not take effective mud to preserve measure, anaerobic ammonium oxidation granular sludge can be dead because of thalline, loses anaerobic ammoxidation activity gradually; On the other hand, the cultivation again of anaerobic ammonium oxidation granular sludge is consuming time longer, is unfavorable for the industrial applications of anaerobic ammonia oxidation process.
Summary of the invention
In order to overcome the problems that the inappropriate preservation of anaerobic ammonium oxidation granular sludge brings, the present invention provides a kind of save set of anaerobic ammonium oxidation granular sludge.
The technical scheme that the present invention adopts is:
A kind of save set of anaerobic ammonium oxidation granular sludge; It is characterized in that: comprise base, be fixedly mounted on container body and gas buffers packet on the said base; The bottom of said container body is provided with mud discharging mouth, and a side of said container body is provided with three water port from top to bottom, and the top of said container body is respectively equipped with mud and adds mouth, ventpipe; Said gas buffer bag is connected with said ventpipe through gas buffer bag blowing mouth, and said gas buffer bag is provided with gas and adds mouth.
Further, said container body is the cylinder bodily form.
Further, said container body is an encloses container.
Further, the mud discharging mouth of said container body, water port, mud add mouthful, and gas buffer bag blowing mouth, gas add mouth and be provided with valve.
Further, said mud adds mouth and can add anaerobic ammonium oxidation granular sludge or nutritive substance.
Further; The add-on of said nutritive substance is 1%～50% of a said container body volume; Interpolation pitch time is 3～15d, and the mol ratio of ammonia nitrogen and nitrite nitrogen is 1:0.8～1.3 in the said nutritive substance, and the concentration of said ammonia nitrogen and nitrite nitrogen independently is 42～98mgL separately

Beneficial effect of the present invention is embodied in:
1, can comparatively secular at ambient temperature preservation anaerobic ammonium oxidation granular sludge, the rate of decay of slowing down sludge activity makes it keep higher anaerobic ammoxidation activity;
2, can utilize the nitrogen that produces between the mud preservation period effectively to realize the anaerobic condition in the container;
3, the interpolation of nutritive substance for anaerobic ammonia oxidizing bacteria in installing provides growth factor, is beneficial to the prolonged preservation of anaerobic ammonium oxidation granular sludge.
