Description
Technical field
The present invention relates to environmental technology field, in particular to a kind of pasture 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 pasture waste water treatment system, which there is processing capacity to utilize by force, conducive to energy recovery
With environmental protection, can reduce water consumption and energy consumption, the advantages that.
To achieve the above object, a kind of pasture waste water treatment system is proposed according to an embodiment of the invention, and the pasture is given up
Water treatment system is included along the sequentially connected pretreatment system in waste water treatment process direction, COD and denitrogenation processing system and depth
Processing system is spent, wherein, the advanced treatment system includes Fenton's reaction device, and the Fenton's reaction device includes Fenton's reaction
Pond has the Fenton's reaction chamber being sequentially communicated along the waste water treatment process direction, PH readjustments chamber, de- in the Fenton's reaction pond
Air cavity and Fenton flocculation chamber, the Fenton's reaction chamber is with acid adds mouth, catalyst adds mouth and oxidant adds mouth, the PH
There is readjustment chamber alkali to add mouth, and the Fenton flocculation chamber has flocculant concentration mouth.
Pasture waste water treatment system according to embodiments of the present invention is utilized by force, conducive to energy recovery with processing capacity and ring
Border protection can reduce the advantages that water consumption and energy consumption.
In addition, pasture 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.
According to one embodiment of present invention, the setting pot is equipped with pretreatment mud scraper.

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 pasture waste water treatment system and is handled.Because wastewater treatment difficulty
Greatly, the processing capacity of pasture waste 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,
Most biochemical substance is consumed naturally in the temporary pool, and the gases such as hydrogen, biogas, hydrogen sulfide of generation directly discharge
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
Add, waste water treatment system treatable water in pasture is less and less, and the wastewater flow rate on the temporary pool continues to increase, pool capacity more dig more
Greatly, an endless loop is ultimately caused.
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 wanting for pasture waste water treatment system biochemistry
It asks, has further resulted in the energy consumption of pasture waste water treatment system.
