Abstract
The invention relates to an enrichment culture method of activated sludge in sewage treatment plants in the plateau alpine region, which comprises the following process steps: 1) bacterium addition; 2) bacterium culture; 3) acclimation; 4) culture completion; wherein the bacterium culture comprises the steps of (a) aeration without water introduction, (b) standing for precipitation, (c) supernatant discharge, (d) intermittent waste water supplement, and (e) bacterium culture completion. The enrichment culture method of activated sludge in sewage treatment plants in the plateau alpine region of the invention overcomes the technical problems of low organic matter concentration of introduced sewage in the plateau alpine region and slow microorganism proliferation due to low temperature, and greatly shortens the culture and acclimation time of activated sludge.
Description
[technical field]
The present invention relates to a kind of active sludge Enrichment culture method, be specifically related to a kind of active sludge Enrichment culture method of frigid plateau region sewage work, belong to technical field of sewage.
[background technology]
The enrichment culture of active sludge is the key that sewage work starts.Active sludge is made up of the residue of the activated microorganism of tool, microorganism autoxidation, the organism that can not be degraded by microorganisms that is adsorbed on active sludge, and wherein microorganism is the chief component of active sludge.The operation of a Sewage treatment systems, the biophase that must have active sludge and adapt with it.So new sewage work of going into operation will carry out cultivation and the domestication of active sludge.
At present, the culturing sludge (abbreviation cultivation) of sewage work mainly adopts two kinds of methods, i.e. Inoculated culture and natural culture method.No matter adopt which kind of method, object is all cultivate high-quality active sludge etc. within the time short as far as possible.The sanitary sewage organic matter of sewage concentration in a lot of city of China is lower, and when BOD5 is less than 100mg/L, microbial reproduction desired nutritional source is not enough, has had a strong impact on zoogleic formation speed.
And in frigid plateau region, more there is the rough sledding such as temperature, air pressure is on the low side, within 3 months to 6 months, be all difficult to be trained required active sludge flora.How to take practical measures, complete and accelerate the cultivation of active sludge, the time needed for starting that shortens as far as possible puts a technical barrier in the field of business.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of active sludge Enrichment culture method with the frigid plateau region sewage work of improved technology, to overcome described defect of the prior art.
[summary of the invention]
For solving the problem, the object of the present invention is to provide a kind of incubation time short and the active sludge Enrichment culture method of the frigid plateau region sewage work of the disadvantageous effect that low water temperature is brought can be solved.
For realizing above-mentioned first object, the technical scheme that the present invention takes is: a kind of active sludge Enrichment culture method of frigid plateau region sewage work, base comprises following processing step: 1), add bacterial classification: aeration tank is filled organic waste water (or with clear water combined sewage to CODcr > 300mg/L), in aeration tank, dehydration activity mud is added by 1% ~ 3% of aeration tank water storage, and adding complete in 2 days, in maintenance aeration tank, activated sludge concentration is at about 1000mg/L; 2), bacterial classification cultivation: (a) is vexed to expose to the sun: open stirrer, aerator blower fan, and the start-stop quantity adjusting aerator blower fan makes dissolved oxygen remain between 0.5 ~ 1mg/L; B () is quiet heavy: all aerator blower fans are stopped 2 hours; C () discharges supernatant liquor, 20% supernatant liquor of draining, and water inlet, continues vexed exposing to the sun 12 hours; D () interval supplements waste water: by the vexed → quiet → continuous above-mentioned steps repeatedly of vexed order of exposing to the sun of sinking of exposing to the sun, when monitoring COD value and reducing by 50% more at first, to the organic waste water of aeration tank complementary design treatment capacity 50%; E () completed cultivation: through the cultivation of 3 ~ 7 days, when aeration tank sludge concentration (MLSS) reaches 1500mg/L, can enter next step; 3), domestication step: by 20% water inlet of designing treatment amount, dissolved oxygen controls between 1.5 ~ 3mg/L; 4), cultivation completed: through the cultivation of 7 ~ 10 days, and can complete cultivation when aeration tank sludge concentration (MLSS) reaches 2500mg/L, Sewage treatment systems can put into operation.
The active sludge Enrichment culture method of frigid plateau region sewage work of the present invention further for: described in the active sludge that adds filter.
The active sludge Enrichment culture method of frigid plateau region sewage work of the present invention is further: the described vexed time of exposing to the sun is 48 hours.
The active sludge Enrichment culture method of frigid plateau region sewage work of the present invention also can be: in described domestication step, and every day increases progressively into water by 10% for the treatment of capacity, until reach designing treatment amount.
Compared with prior art, the present invention has following beneficial effect: the active sludge Enrichment culture method of frigid plateau region sewage work of the present invention overcomes the microbial growth technical barrier slowly that wastewater influent organic concentration low and low temperature in frigid plateau region causes, and it can shorten cultivation and the domestication time of active sludge greatly.
[embodiment]
The present invention is a kind of active sludge Enrichment culture method of frigid plateau region sewage work, and it comprises following processing step:
1), bacterial classification is added
Aeration tank is filled organic waste water (or with clear water combined sewage to CODcr > 300mg/L), in aeration tank, dehydration activity mud is added by 1% ~ 3% of aeration tank water storage, and adding complete in 2 days, in maintenance aeration tank, activated sludge concentration is at about 1000mg/L; Wherein, the active sludge added described in filters;
2), bacterial classification cultivation
A () is vexed exposes to the sun: open stirrer, aerator blower fan, and the start-stop quantity adjusting aerator blower fan makes dissolved oxygen remain between 0.5 ~ 1mg/L; The described vexed time of exposing to the sun is 48 hours;
B () is quiet heavy: all aerator blower fans are stopped 2 hours;
C () discharges supernatant liquor, 20% supernatant liquor of draining, and water inlet, continues vexed exposing to the sun 12 hours;
D () interval supplements waste water: by the vexed → quiet → continuous above-mentioned steps repeatedly of vexed order of exposing to the sun of sinking of exposing to the sun, when monitoring COD value and reducing by 50% more at first, to the organic waste water of aeration tank complementary design treatment capacity 50%;
E () completed cultivation: through the cultivation of 3 ~ 7 days, when aeration tank sludge concentration (MLSS) reaches 1500mg/L, can enter next step;
