Description
Technical field
The present invention relates to anaerobic reactor devices, and in particular to removes eutrophic water using water body original inhabitants denitrifying bacteria
A kind of electric energy anaerobic reactor device applied in natural water and its application method of heavy metal and nitrate nitrogen in body.
Background technology
Eutrophication of natural water and heavy metal pollution are always current most common combined pollution.Eutrophication is current
Important behaviour in conventional pollution, as the mankind increasingly increase environmental resource utilization activity, particularly industrial and agricultural production
Extensive development, largely the sewage containing compound fertilizer be discharged into neighbouring natural water body, add the battalion of these water bodys
Substance load is supported, essential problem is the multifarious destruction of aqueous bio, and the system that thereby results in is lost self―sustaining, self adjusted
The ability of section and system balancing unstability accelerate the speed of body eutrophication.And in the discharge process of sewage, pollutant
Heavy metal retaining in water body water body is also increasing, and heavy metal retaining in water body accumulates and the features such as migration increases
The difficulty that heavy metal in water has been added to purify.Simultaneously as heavy metal has, source is wide, the residence time is long, has accumulation property, can not drop
Solution can not only endanger Fishery Water Environment and aquatile, also endanger human health along the features such as food chain transport.Therefore compel
Being essential will be administered and be repaired to the water body water body of nitrate nitrogen and heavy-metal composite pollution.
The existing administering method for polluted water body can be divided into Physical, chemical method, bioanalysis, restoration of the ecosystem
Four major classes, and many method for treating water technological processes are very ripe, but deposited for the improvement of the open water body such as water body, river
In significant limitation.Therefore, from financial cost and recycling angularly, economical and efficient, energy-saving and environment-friendly water are explored
Weight metal purification method and device is the difficult point that current heavy metal pollution of water body is administered.
The content of the invention
Present invention aims to overcome that the deficiencies in the prior art, it is anti-to provide a kind of electric energy anaerobism applied in natural water
Answer device device and its application method.
A kind of electric energy anaerobic reactor device applied in natural water, including anaerobic reactor, into water conduit tube, water outlet
Main pipe, interior return duct, pump, generator and accumulator；The anaerobic reactor includes reaction kettle and electric heating assembly, and anaerobism is anti-
It answers and is provided with one-way exhaust valve at the top of device；The closed tank body that the reaction kettle is vertically arranged, reaction kettle be divided into reaction kettle top,
In the middle part of reaction kettle and reaction kettle lower part, setting three phase separator in reaction kettle top, reaction kettle top is provided with water outlet, described
Water outlet be connected with the water conduit tube that goes out, in the middle part of the reaction kettle in be equipped with spacer-frame, spacer-frame is thin full of denitrification
Bacterium activates filler material, and the denitrifying bacteria activates filler material with inorganic carrying body, inorganic flocculate, inorganic metal salt, work
Property charcoal is prepared for raw material, and the mass ratio of four kinds of raw materials is followed successively by (1~8)：(0~0.5)：(0~0.5)：(2~4), wherein
The quality of inorganic flocculate and inorganic metal salt ratio value range is more than 0 and less than or equal to 0.5, and four kinds of raw materials are abundant
Be uniformly mixed and be scattered in 60~80 DEG C of water, denitrifying bacteria activator is added in after cooling, then in the case where being sufficiently stirred with 3~
The organic high molecular polymer that the speed instillation of 4ml/min is dissolved in the water, organic high molecular polymer is used for denitrification is thin
Bacterium activator is fixed on inorganic carrying body surface, and after cooling precipitates, lower part deposit is the denitrifying bacteria activation filling
Material, the inorganic carrying body are one kind in silica gel, montmorillonite or diatomite, and the inorganic flocculate is aluminium polychloride
(PAC), one kind in polyaluminium sulfate (PAS), bodied ferric sulfate (PFS) or poly-ferric chloride (PFC), the inorganic metal
The one kind of salt for sodium chloride, in potassium chloride, the denitrifying bacteria activator ingredient is frerrous chloride, sodium acetate, peptone,
Yeast extract, glucose, sodium chloride, agar, potassium nitrate, mass ratio is followed successively by (1~1.5) during addition：(2~2.5)：(15~
16)：(3~3.5)：(1~1.5)：(6~6.5)：(12~13)：(2~2.5)；Water distributor, cloth are provided in reaction kettle lower part
