Detailed description of the invention
The invention discloses a kind of municipal sewage and method that mud works in coordination with circular treatment, comprise the steps:
The first step: municipal sewage becomes qualified discharge through the process of grid, setting pot and sewage disposal system, sewage
Water and mud；
Second step: mud preheats through pulp, completes mud organic substance pyrohydrolysis in entering into sludge hot hydrolytic reaction pot
Reaction, in pyrohydrolysis course of reaction, the larger molecular organics in mud is pyrolyzed into little molecule and the most biochemical Organic substance, the most such as
Under: sludge protein hydrolysis of organic matter becomes polypeptide and aminoacid, mud cell wall fiber type organic to be hydrolyzed into fructose and Fructus Vitis viniferae
Sugar, mud fats hydrolysis of organic matter becomes fatty acid and triglyceride etc.；
3rd step: the high temperature mud after pyrolysis is cooled to through guanite dephosphorization process dephosphorization and part ammonia nitrogen, cooled device
Normal pressure, enters sewage disposal system, successively collaborative place of moving in circles after being back to Sewage Plant water inlet, and municipal sewage mixing
Reason.
In described second step, the mud of generation, after pulp preheating can 5 processes, enters into sludge hot hydrolysis
Completing the reaction of mud organic substance pyrohydrolysis in still 6, in pyrohydrolysis course of reaction, the larger molecular organics in mud is pyrolyzed into little
Molecule and the most biochemical Organic substance, the temperature after mud pulp preheating: 55 DEG C-80 DEG C, mud enters sludge hot hydrolytic reaction pot, note
Entering superheated steam, final pyrolysis mud temperature is heated to: 140 DEG C-170 DEG C, when mud stops in sludge hot hydrolytic reaction pot
Between 13 minutes to 20 minutes, whole process is a continuous print technical process.
In described second step, mud reacts through sludge hot hydrolytic reaction pot 6, becomes liquid state mud, solubility
COD has accounted for 95%, BOD/COD >=0.6.
In described second step, mud and steam rates are that mud per ton adds 110 to 130 kilogram of steam.
As the preferred embodiments of the present invention, in described second step, when mud stops in sludge hot hydrolytic reaction pot
Between 15 minutes or 18 minutes, final pyrolysis mud temperature is heated to 155 DEG C.
In described 3rd step, in guanite dephosphorization process the chemical feeding quantity of magnesium chloride be aqueous 80% raw sewage ten thousand/
1.2。
In described 3rd step, guanite dephosphorization process Chinese medicine selects magnesium hydroxide.
As it is shown in figure 1, the invention also discloses a kind of municipal sewage and mud works in coordination with the device of circular treatment, including successively
The sewage disposal system 3 being connected, dirty slurry dewaterer 4, mud preheating pulp tank 5, sludge hot hydrolytic reaction pot 6, guanite dephosphorization
System 7, cooler 8, this device also includes the steam generator system 9 providing steam for described sludge hot hydrolytic reaction pot 6, described boiler
System 9 is connected with described sludge hot hydrolytic reaction pot 6.
This device also includes grid 1 and the sand setting being arranged between municipal sewage outlet and described sewage disposal system 3
Pond 2, this device also includes that flash tank 10, condenser 11, deodoration system 12, described flash tank 10 connect described mud hot water respectively
Solution reaction kettle 6 and described mud preheating pulp tank 5, described condenser 11 input connects described mud preheating pulp tank 5, described
Condenser 11 outfan connects described deodoration system 12, and described deodoration system 12 connects described dirty slurry dewaterer 4 and described respectively
Sewage disposal system 3.
High temperature mud after pyrolysis is cooled to normal pressure through guanite dephosphorization system 7 dephosphorization and part ammonia nitrogen, cooled device 8,
Sewage disposal system 3 is entered after being back to Sewage Plant water inlet, and municipal sewage mixing.
This deodoration system 12 processes sewage disposal system 3 and the low concentration foul smell of Dehydrator for Slurry 4 generation, processes dirt simultaneously
Mud preheating pulp tank 5 high concentration foul smell out.
The present invention has a following technical advantage:
1. the present invention solves a municipal sewage plant specific resistance to filtration difficult problem, and no matter present specific resistance to filtration is mud
Anhydration and incineration or the technique such as Sludge landfill or sludge composting, all can bring secondary pollution to environment, as sludge incineration produces
The harmful substances such as dioxin carcinogen and heavy metal gaseous state glue, Sludge landfill produces high concentration penetrating fluid polluted underground water, simultaneously
Producing the air ambient that substantial amounts of odor pollution periphery is neighbouring, Treatment of Sludge project all receives the people's around project pick-up point
Neck keeps away resistance.
2. the problem that during the present invention solves mud factory sewage disposal process, carbon source is not enough, the pyrolysis mud after pyrohydrolysis is rich
Supplement carbon source after carbon source, and municipal sewage mixing, need not separately add methanol etc., reduce operating cost.
In sewage the most of the present invention and mud same system, treatment in situ is disposed, and changes existing sewage disposal and Treatment of Sludge
Pattern, solves mud outward transport, a process difficult problem of separately founding the factory, the difficulty that present China is landed by mud project in a lot of city.
4. the sludge treatment technique of the present invention solves a mud supervision and management difficult problem, solves the illegal unrest of mud and pollutes ring
The difficult problem in border.
5. the sewage sludge of the present invention process disposing technique than traditional sewage sludge process cost of disposal save 20% with
On.
The collaborative process of sewage sludge the most of the present invention circulation disposes the civilization embodying ecology, and mud comes to go back to there more therefrom
Going, lattice keep the ecological replacement made the best use of everything.
7. the guanite dephosphorization of the present invention, eliminates the phosphorus in sewage sludge and part ammonia nitrogen, and guanite returns as fertilizer
Return Natural Circulation.
8. sewage disposal, Treatment of Sludge and odor treatment are considered by the present invention in the lump, define the solution of a closed loop
Certainly scheme, and traditional sewage and mud comparison of item, reduce general item investment expense.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert
Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of present inventive concept, it is also possible to make some simple deduction or replace, all should be considered as belonging to the present invention's
Protection domain.
