Description
Technical field
The present invention relates to sewage water treatment method more particularly to a kind of sludge reduction sewage water treatment methods.
Background technology
As China's urbanization and Industrial Waste Water Treatments ability greatly improve, generated in corresponding sewage disposal process
Surplus sludge volume is also increasingly huge, and every year with 10%~15% speed increase, and sludge pollution is on the rise, and Treatment of Sludge is asked
Topic highlights.The current sludge in China is mainly with formal layouts such as compost, landfills, in mix, if not processing sludge mistake
The excess sludge generated in journey is disposed, and the pollutants such as pathogenic microorganism contained therein, heavy metal are transferred in ambient enviroment
Cause secondary pollution.
People are concentrated mainly on end treatment to the processing concern of Treatment of Sludge, and the process that seldom sludge occurs is ground
Study carefully.The Sludge Reduction Technologies studied both at home and abroad at present mainly have ozonation technology, ultrasonic disruption cell technology, uncoupling skill
Art, soda acid dissolving technology, but all there are of high cost or technical bottlenecks, do not form certain market application.Sludge at present
The huge sludge output for the treatment of plant has been highlighted with the incomplete contradiction of sludge disposal technology, if not controlling the yield of sludge,
Sludge is made to be reduced from source, and only with end treatment, then no matter using which kind of Treatment of Sludge or disposal technology, all difficult handle
Sludge problem is resolved.
Invention content
The present invention is directed to the shortcomings that sludge yield in existing sewage disposal technology is huge, and Treatment of Sludge is difficult, of high cost, carries
A kind of sludge reduction sewage water treatment method being reduced from the source generated from sludge is supplied.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals:
A kind of sludge reduction sewage water treatment method, includes the following steps:
Step (1):Sewage in regulating reservoir sequentially enters the anaerobic reaction stage, and sedimentation basin, precipitation separation are entered after reaction
Sewage enter aerobic reaction stage, sludge reflux to regulating reservoir;
Step (2):For sewage after the aerobic reaction stage, filtering precipitation precipitates the sludge reflux of separation to regulating reservoir, water
Matter stably reaches national secondary discharge standard;
Wherein, packing specific area >=20m used in aerobic reaction stage and anaerobic reaction stage2/ g, porosity of=
90%, strain includes acinetobacter, Lampropedia, chromabacterium biolaceum category, double bacterium, lactic acid bacteria, bacillus, acetic acid in sludge
Bacterium, actinomyces, saccharomycete, fusobacterium.
Sewage disposal is handled using Mixed Microbes, can digest having in sewage by the different metabolic path of different microorganisms
Machine object reduces the content of organics of sewage;Containing clostridium microorganism belonging to genus in Mixed Microbes, can digested sludge, play mud decrement
The purpose of change.
Preferably, in step (1), the anaerobic reaction stage includes passing through first order anaerobic reaction stage and the second level successively
The anaerobic reaction stage.In the first order anaerobic reaction stage, facultative and anaerobe raised growth, in second level anaerobic reaction rank
Section, anaerobic bacteria largely consume the organic matter in sewage, reduce the COD value of sewage.
Preferably, in step (2), the aerobic reaction stage includes passing through first order aerobic reaction stage and the second level successively
The aerobic reaction stage.In the first order aerobic reaction stage, facultative and aerobic microbiological raised growth, in the second aerobic reaction rank
Section, aerobic bacteria largely consume the organic matter in sewage, reduce the COD value of sewage.
Preferably, in step (2), using biochemical filtration, filter medium is the stack layer that sandstone is formed for filtering.Sandstone or
Gravel is accumulated to form stack layer as filter medium, can effectively intercept the bacterium mud in sewage, good filtration effect is efficient, together
When have many advantages, such as that slag dumping is convenient.
Preferably, fusobacterium viable count accounts for 50% or more of all number of viable in sludge.Fusobacterium obligate anaerobic,
Mostly several is chemoheterotrophic bacteria;Some chemoautotrophic bacterias or chemolithotrophy.It can be with hydrolysis sugar, protein, or both all
Nothing or both all has.They usually generate the organic acid and alcohols of mixing from sugar or peptone.
The present invention sludge include fusobacterium, aerobic stage can a large amount of digested sludges, reach sludge reduction arrange
The demand put, reduces Sludge in Sewage Treatment cost of disposal, greatly reduces artificial and operating cost.
