Description
Technical field
The present invention relates to technical field of sewage more particularly to a kind of exploitation of biodegradability carbon source and preposition denitrogenation systems
System.
Background technique
In sewage disposal system, in mud discharging in secondary settling tank to reflux well, then concentration is discharged by reflux well
Chi Zhong, the supernatant after concentration re-enter into the water circulation of sewage treatment, and the sludge after concentration transports outward discharge, in fact, from
The sludge volatile organic matter content that well is discharged that flows back is 68% or so, if the directly concentration discharge that is not used will cause
The very big wasting of resources.
Summary of the invention
Volatile organic matter in sludge can be recycled benefit technical problem to be solved by the invention is to provide a kind of
The exploitation of biodegradability carbon source and preposition denitrification system.
In order to solve the above technical problems, the technical scheme is that biodegradability carbon source exploitation and preposition denitrification system,
Including preposition denitrification tank, the top water inlet of the preposition denitrification tank is connected with lift pump room, the promotion by riser tubing
Pump house is connected to wastewater influent total pipeline；It further include the reflux well being connected to the spoil disposal port of biochemical system, the reflux well is logical
It crosses sludge feedback pipeline to be connected to the lift pump room, feedback control valve is installed on the sludge feedback pipeline.
As a kind of perferred technical scheme, the inner tip of the preposition denitrification tank is equipped with one end and the riser
The transverse tube of road connection.
As a kind of perferred technical scheme, the control valve that shuts off is installed on the transverse tube.
By adopting the above-described technical solution, the exploitation of biodegradability carbon source and preposition denitrification system, including preposition denitrification tank,
The top water inlet of the preposition denitrification tank is connected with lift pump room by riser tubing, and the lift pump room and wastewater influent are total
Pipeline connection；Further include the reflux well being connected to the spoil disposal port of biochemical system, the reflux well by sludge feedback pipeline with
The lift pump room is connected to, and is equipped with feedback control valve on the sludge feedback pipeline；Sludge is discharged to preposition denitrogenation in reflux well
After pond staticly settles concentration, by anaerobic digestion, the organic matter of itself is re-converted into biodegradability organic matter and returns to active dirt
In mud system, biochemical carbon source is increased, meets denitrifying primary condition, the nitrate nitrogen in water inlet can be shifted to an earlier date
Removal, reaches the recycling of carbon source and realizes preposition denitrogenation.
Detailed description of the invention
The following drawings are only intended to schematically illustrate and explain the present invention, not delimit the scope of the invention.Wherein:
Fig. 1 is the schematic diagram of the embodiment of the present invention；
In figure: 1- riser tubing；21- sludge feedback pipeline；22- feedback control valve；31- transverse tube；32- shuts off control valve.
Specific embodiment
With reference to the accompanying drawings and examples, the present invention is further explained.In the following detailed description, only pass through explanation
Mode describes certain exemplary embodiments of the invention.Undoubtedly, those skilled in the art will recognize,
In the case where without departing from the spirit and scope of the present invention, described embodiment can be repaired with a variety of different modes
Just.Therefore, attached drawing and description are regarded as illustrative in nature, and are not intended to limit the scope of the claims.
As shown in Figure 1, the exploitation of biodegradability carbon source and preposition denitrification system, including preposition denitrification tank, the preposition denitrogenation
The top water inlet in pond is connected with lift pump room by riser tubing 1, and the lift pump room is connected to wastewater influent total pipeline；Also
Including the reflux well that the spoil disposal port with biochemical system is connected to, the reflux well passes through sludge feedback pipeline 21 and the elevator pump
Room is connected to, and is equipped with feedback control valve 22 on the sludge feedback pipeline 21.
The inner tip of the preposition denitrification tank is equipped with the transverse tube 31 that one end is connected to the riser tubing 1.The cross
The control valve 32 that shuts off is installed on pipe 31.
Sludge is discharged to after preposition denitrification tank staticly settles concentration in reflux well, by anaerobic digestion, the organic matter weight of itself
It is newly converted into biodegradability organic matter to return in activated Sludge System, increases biochemical carbon source, meet denitrifying basic
Condition can remove the nitrate nitrogen in water inlet in advance, reach the recycling of carbon source and realize preposition denitrogenation.
Measurement by 1 year: the excess sludge volatile organic matter content being discharged from reflux well is 68% or so,
It is staticly settled in preposition denitrification tank, volatile organic matter content is 50.7% after anaerobic digestion.Also that is, by detesting
Oxygen resolution, has 17.3% biochemical organic matter to return in activated Sludge System, supplements carbon source required for denitrogenation, meets anti-nitre
Change condition realizes preposition denitrification functions.The exploitation of biodegradability carbon source had both solved the problems, such as that sewerage carbon source was insufficient, and
And the volume and weight of discharge sludge can also be reduced, reduce the operating cost of enterprise.
The above shows and describes the basic principle, main features and advantages of the invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
