Description
Technical field
The invention belongs to municipal sewage treatment applied technical fields, and in particular to a kind of efficient process for municipal sewage
System.
Background technique
Sewage refers to the general name of the water discharged in production and life activity, loses the original water for using function and is referred to as
Sewage, sewage are to cause aqueous metamorphism cannot be after continuation of insurance due to being mixed with new substance in water or because of the variation of external condition
Hold original use function.
The harm of water pollution is various, wherein the influence to human health is to cause acute and chronic poisoning, water
After body is polluted by toxic and harmful substance, poisoning just may cause by drinking-water or food chain, such as famous minamata disease, pain pain
Disease is as caused by water pollution；Carcinogenesis, certain chemical substances for having carcinogenesis such as arsenic, chromium, nickel, beryllium, aniline, benzo
(a) after pyrene and other polycyclic aromatic hydrocarbons, contaminated with halogenated hydrocarbons water body, it can be suspended object, bed mud absorption, it can also be in aquatic organism inner product
Tired, long-term drinking contains the water of this substance, or edible accumulation in vivo has the biology (such as fish) of this substance that may induce
Cancer；Occur using water as the infectious disease of medium.The biological pollutants polluted-water such as human and animal excreta may cause bacillary enteron aisle and pass
It catches an illness such as typhoid fever, dysentery, enteritis, cholera；Common virus such as gray nucleus viroid, Coxsackie virus, infectiousness in enteron aisle
Hepatitis virus etc. can all cause corresponding infectious disease by water pollution；It influences indirectly, after water pollution, can often cause water
Sensory properties deteriorates, and such as certain pollutants are under a certain concentration, though water generation can be made different without directly endangering the health of people
It is smelly, heterochromatic, foam and oil film etc. is presented, interferes the normal utilization of water body.The substances such as copper, zinc, nickel can inhibit under a certain concentration
The growth and breeding of microorganism decline water body self-purification ability to influence the decomposition and biological oxidation of Organic substance in water, influence
The sanitary condition of water body.
Water pollution can both seriously endanger the ecosystem, can also cause serious economic loss, so current water pollution
Improvement has attracted people's attention, and before the sewage such as production, life are discharged, needs to carry out a series of processing, so that
Its standard for reaching discharge.
Currently, being used for the processing system of municipal sewage, design is unreasonable, cannot mix in efficient, high-quality removal sewage
Harmful substance and solid sundries for entering etc., i.e. municipal sewage treatment quality are low, the sewage treatment time is long, at high cost etc..
Therefore, based on the above issues, the present invention provides a kind of efficient process system for municipal sewage.
Summary of the invention
Goal of the invention: the object of the present invention is to provide a kind of efficient process system for municipal sewage, design rationally,
Stable working state and can efficiently remove harmful substance such as COD, NH3-N, T-N in sewage etc., improve sewage treating efficiency and
Quality is handled, shortens the processing time of sewage, reduces cost.
Technical solution: the present invention provides a kind of efficient process system for municipal sewage, including sequentially connected thick lattice
Grid, inlet pumping station, fine fack, setting pot, the first distribution well, primary sedimentation tank, aeration tank, the second distribution well, secondary settling tank, the first sewage
Pump house, concentration basin, sludge homogeneous pond, thickening computer room；The sewage is successively carried out different by above system component parts
Procedures processing, and final sludge is transported outward.
The technical program, the efficient process system for municipal sewage, further include respectively with primary sedimentation tank, aeration tank
The second sludge pump house, the air blast computer room of connection, wherein the second sludge pump house is connect with sludge homogeneous pond.
The technical program, the returned sludge of first sewage pump plant is back to aeration tank through pipeline.
The technical program, grid slag, the dry sand after coarse rack, fine fack, setting pot processing filter out outward transport.
The technical program, the qualified sewage after primary sedimentation tank, secondary settling tank processing is discharged.
Compared with prior art, a kind of beneficial effect of the efficient process system for municipal sewage of the present invention is: its
Design reasonable, stable working state and can efficiently remove harmful substance such as COD, NH3-N, T-N in sewage etc., it improves at sewage
Efficiency and processing quality are managed, shortens the processing time of sewage, reduces cost.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of efficient process system for municipal sewage of the invention;
Fig. 2 is a kind of water outlet detection data of efficient process system for municipal sewage of the invention.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated.
A kind of efficient process system for municipal sewage as shown in Figure 1, including sequentially connected coarse rack, intake pump
Room, fine fack, setting pot, the first distribution well, primary sedimentation tank, aeration tank, the second distribution well, secondary settling tank, the first sewage pump plant, concentration
Pond, sludge homogeneous pond, thickening computer room；The sewage successively carries out different procedures by above system component parts
Reason, and final sludge is transported outward.
It is further preferred that the efficient process system for municipal sewage, further include respectively with primary sedimentation tank, aeration tank
The second sludge pump house, the air blast computer room of connection, wherein the second sludge pump house is connect with sludge homogeneous pond；And first sewage
The returned sludge of pump house is back to aeration tank through pipeline；And the grid slag, dry sand after coarse rack, fine fack, setting pot processing
Filter out outward transport；And the qualified sewage after primary sedimentation tank, secondary settling tank processing is discharged.
Through this system, treated that COD index is as shown in the table,
；
Through this system, treated that NH3-N index is as shown in the table,
；
Through this system, treated that T-N index is as shown in the table,
。
Efficient process system for municipal sewage of the invention, treatment scale are 8.5 ten thousand m3/d.
