Description
Technical field
The invention belongs to environmental protection technical field, more particularly to a kind of process municipal sludge
The method of anaerobic digestion solution and its equipment.
Background technology
Depth with the popularization of municipal wastewater treatment facility, the raising of handling rate and degree for the treatment of
Change, the mud yield of municipal sewage plant has larger growth, the secondary pollution thus causing
Problem is increasingly severe.The mud of municipal wastewater treatment plant refers to process produced by sewage admittedly
The garbage of state, semisolid and liquid, containing substantial amounts of Organic substance, heavy metal and cause a disease
Bacterium and pathogen etc., untreated any discharge, can cause serious pollution to environment.Right
The total requirement of Treatment of Sludge is stabilisation, innoxious and minimizing.
The method of Treatment of Sludge and disposal a lot, typically using concentration, digests, takes off both at home and abroad
Water, mummification, effectively utilizes (agricultural, building materials etc.), landfill and burning etc., or with wherein
Several Combination of Methods are disposed.Should say, the process to sewage plant sludge and disposal, Wo Menyu
Advanced country compares, and gap is larger.
Sludge stabilization process have aerobic and anaerobism point, aerobic stabilization has many good qualities, but energy
Consumption is very high, just adopts only when sludge quantity is less.Sludge anaerobic stabilized treatment generally adopts
Middle temperature (35 DEG C) and two kinds of anaerobic digestion process of high temperature (55 DEG C).Domestic existing a lot of seats
Large-scale wastewater treatment plant adopts the method, and after digestion, content of organics reduces mud, property
Can be stable, cumulative volume reduces, and also produces a large amount of biogas recoverables in sludge digestion process.
Sludge aerobic digestion device complex process, one-time investment is big, runs difficult.From
The actual motion of built digester sees, only minority gets a desired effect.There is management, set
Meter problem, also has economy and the safety issue of biogas utilization.But in recent years, with state
The attention to Treatment of Sludge for the family, the maturation of anaerobic digestion process equipment, and to anaerobic digestion
Experienced technology, operation, the increase of management personnel, anaerobic sludge digestion treatment facility is in
The trend now increasing.
The high-temperature-hot-water solution of some sludge pretreatments, high temperature alkali solution technology be at home in recent years
Invent outward and be applied to engineering practice, through high-temperature-hot-water solution pretreating sludge breaking cellular wall
Afterwards, the anaerobic digestion of mud becomes easier to, and gas production increases a lot, this facilitates everybody
The enthusiasm that anaerobic sludge digestion is processed.But another the very important problem brought
It is exactly the intractability increase of anaerobic digestion solution.
Sludge-digestion liquid typically has the following characteristics that
1st, ammonia nitrogen concentration is high.The ammonia nitrogen concentration of general sludge-digestion liquid is 500～1500mg/l,
And the mud processing through high-temperature-hot-water solution, the ammonia nitrogen concentration of Digestive system 2500～
4000mg/l, if so high concentration adopts common biochemical treatment, can exist larger
Intractability, and using as the processing method of stripping and steam air stripping, the high owner of operating cost
It is difficult to bear.The TAN of sludge-digestion liquid can account for sewage treatment plant's TAN
20～80%, if these sludge-digestion liquid are back to municipal sewage system, meeting
System loading is caused to increase a lot, it is therefore proposed that sludge-digestion liquid individual processing.
2nd, carbon-nitrogen ratio is unbalance.The cod/tn ratio of sludge-digestion liquid is typically 1.0～4.0
Between, sufficient aeration is needed using common " nitrification-denitrification " technique and adds big
Total nitrogen in Digestive system could be removed by the carbon source of amount, alkali, and this costly arrives most of dirt
Water treatment plant is difficult to bear.
" anaerobic ammonia oxidizing bacteria " (anaerobic ammonium oxidation, anammox)
It is the special engineered bacterial of a class, by biochemical reaction, they can be by institute in sewage
The ammonia nitrogen containing and nitrite nitrogen are converted into nitrogen and remove.And this antibacterial in conversion process
Do not need oxygen, do not need carbon source, therefore the biology Ji Yu " Anammox " mechanism takes off
Nitrogen technology has big advantage.For the above feature of sludge-digestion liquid, based on " anaerobism
Ammoxidation " biological denitrificaion mechanism, designs and can take into account organic matter removal and efficient ammonia nitrogen simultaneously
The technique that/total nitrogen removes, is the emphasis of the present invention.
