Description
Technical field
The present invention relates to environmental technology field, in particular to a kind of waste water treatment system.
Background technology
Pasture waste water mostlys come from cowshed and Nai Ting ground flushings workshop section, and water consumption is big, COD in waste water, nitrogen, phosphorus, solid
Body suspended matter and salinity are higher, and hard-degraded substance is more, and intractability is high.Pasture waste water treatment system processing in the relevant technologies
Ability is poor, and waste water is longer in the temporary pool residence time, causes energy waste and environmental pollution, and water consumption and energy consumption are higher.
Invention content
The present invention is directed to solve one of above-mentioned technical problem in the relevant technologies at least to a certain extent.For this purpose, this hair
Bright to propose a kind of waste water treatment system, which there is processing capacity to protect by force, conducive to energy recovery utilization and environment
Shield, can reduce water consumption and energy consumption, the advantages that.
To achieve the above object, a kind of waste water treatment system, the wastewater treatment system are proposed according to an embodiment of the invention
System is included along the sequentially connected pretreatment system in waste water treatment process direction, COD and denitrogenation processing system and advanced treating system
System, wherein, the advanced treatment system includes Fenton's reaction device, and the Fenton's reaction device includes Fenton's reaction pond, described
Have in Fenton's reaction pond the Fenton's reaction chamber being sequentially communicated along the waste water treatment process direction, PH readjustments chamber, adsorbent chamber and
Fenton flocculation chamber, the Fenton's reaction chamber is with acid adds mouth, catalyst adds mouth and oxidant adds mouth, the PH readjustments chamber
Mouth is added with alkali, there is the adsorbent chamber adsorbent to add mouth, and the Fenton flocculation chamber has flocculant concentration mouth.
There is waste water treatment system according to embodiments of the present invention processing capacity to protect by force, conducive to energy recovery utilization and environment
Shield can reduce the advantages that water consumption and energy consumption.
In addition, waste water treatment system according to embodiments of the present invention can also have following additional technical characteristic：
According to one embodiment of present invention, the pretreatment system includes successively connecting along the waste water treatment process direction
Setting pot, solid-liquid separator and the adjusting tank connect.

Specific embodiment
The embodiment of the present invention is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Pasture waste water treatment process in the relevant technologies is by the waste water desilting of generation, and cleaning up excrement is guided to temporary with after sieving
The pool temporarily stores, then the waste water in the temporary pool is introduced into waste water treatment system and is handled.Because wastewater treatment difficulty is big, give up
The processing capacity of water treatment system is limited, and residence time of the waste water on the temporary pool is very long, often at 10 days or more, it is most can
Biochemical substance is consumed naturally in the temporary pool, and the gases such as hydrogen, biogas, hydrogen sulfide of generation are directly released into air,
The significant wastage of the energy is caused, also results in the pollution of exhaust gas in pasture.
Simultaneously because biochemical substance is consumed naturally in the temporary pool in waste water, the degree difficult to degrade of waste water continues to increase
Adding, the treatable water of waste water treatment system is less and less, and the wastewater flow rate on the temporary pool continues to increase, and pool capacity the more digs the more big,
Ultimately cause an endless loop.
It naturally volatilizees with the waste water on the temporary pool, the salinity in waste water gradually rises, and the degree difficult to degrade of waste water continues
Increase, the value of reuse also reduces, and further increases the dosage of fresh water, and the water rate for improving pasture is used.
If the waste water in the temporary pool introduces biochemical system, since biochemical system needs to maintain certain water temperature, due to that can give birth to
The consumption of compound matter, the heat generated in biochemical treatment of wastewater can not meet the requirement of waste water treatment system biochemistry, into
One step causes the energy consumption of waste water treatment system.
In view of the pasture wastewater processing technology situation in the relevant technologies, it is strong, sharp that the present invention proposes a kind of processing capacity
It is utilized in energy recovery and environmental protection, water consumption and energy consumption can be reduced, waste water treatment system 1 is at the waste water of pasture
Reason.
Below with reference to the accompanying drawings waste water treatment system 1 according to embodiments of the present invention is described.

Fenton flocculation chamber 4112 has flocculant concentration mouth 4126.
In other words, acid adds mouth 4121, catalyst adds mouth 4122 and oxidant adds mouth 4123 and Fenton's reaction chamber
4111 connections, for launching sour (such as sulfuric acid), catalyst (such as ferrous sulfate) and oxidation to Fenton's reaction chamber 4111 respectively
Agent (such as hydrogen peroxide).Alkali adds mouth 4124 and is connected with PH readjustment chambers 4115, for launching alkali to PH readjustment chambers 4115.Adsorbent
It adds mouth 4125 to connect with adsorbent chamber 4116, for adding adsorbent (such as activated carbon) to adsorbent chamber 4116.Flocculant concentration
Mouth 4126 is connected with Fenton flocculation chamber 4112, for launching flocculant to Fenton flocculation chamber 4112.
It needs exist for being appreciated that, acid adds mouth 4121, catalyst adds mouth 4122, oxidant adds mouth 4123, alkali is thrown
Add that mouth 4124, adsorbent add mouth 4125, flocculant concentration mouth 4126 can be arranged on Fenton's reaction pond 4110；It can also make
The upper surface in Fenton's reaction pond 4110 is opened wide, and acid is made to add mouth 4121, catalyst adds mouth 4122, oxidant adds mouth
4123rd, alkali adds mouth 4124, adsorbent adds mouth 4125, flocculant concentration mouth 4126 is suspended in 4110 top of Fenton's reaction pond.
It will be appreciated by those skilled in the art that ground is, waste water treatment process direction refers to, in whole works of wastewater treatment
In sequence, along the ordering of each process, waste water is from the first procedure sequentially into the flow direction of last procedure.
Below with reference to the accompanying drawings the wastewater treatment process of waste water treatment system 1 according to embodiments of the present invention is described.
Waste water enters pretreatment system 70, and pretreatment system 70 removes the suspended matter in waste water, and to sandstone and water quality water
It measures into row buffering, waste water enters COD and denitrogenation processing system 80 later, removes the COD (organic pollution) in waste water and denitrogenation,
Last waste water enters advanced treatment system 60, and further removing can not biodegradable organic pollution in waste water.
Waste water treatment system 1 according to embodiments of the present invention by setting pretreatment system 70, utilizes pretreatment system 70
The temporary storage for mobile agent pool solves the problem of that waste water goes oil removal sandstone and water quality and quantity to buffer, and 1 disposed of in its entirety of waste water treatment system
