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 solar anaerobic reactor assembly applied in processing unit 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, provide a kind of solar anaerobic applied in processing unit
Reactor assembly and its application method.
A kind of solar anaerobic reactor assembly applied in processing unit, including into water conduit tube, go out water conduit tube, interior time
Flow tube, pump, accumulator, photoelectric controller, inverter and generator；The anaerobic reactor includes reaction kettle, electrical heating group
Part and solar photovoltaic assembly, anaerobic reactor top are provided with one-way exhaust valve；The reaction kettle is vertically arranged closed
Tank body, reaction kettle are divided into reaction kettle top, reaction kettle middle part and reaction kettle lower part, three phase separator are set in reaction kettle top,
Reaction kettle top is provided with water outlet, and the water outlet is connected with the water conduit tube that goes out；It is set in the middle part of the reaction kettle
There is spacer-frame, spacer-frame activates filler material full of denitrifying bacteria, and the denitrifying bacteria activates filler material with inorganic carrying
Body, inorganic flocculate, inorganic metal salt, activated carbon are 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 be more than 0 and
Less than or equal to 0.5, the four kind raw material is sufficiently mixed and is dispersed in 60~80 DEG C of water, and denitrifying bacteria is added in after cooling and is swashed
Agent living, the organic high molecular polymer being then dissolved in the water in the case where being sufficiently stirred with the speed instillation of 3~4ml/min are organic
High molecular polymer is used to denitrifying bacteria activator being fixed on inorganic carrying body surface, after cooling precipitates, lower part deposit
As denitrifying bacteria activation filler material, the inorganic carrying body are one kind in silica gel, montmorillonite or diatomite, institute
Inorganic flocculate is stated as aluminium polychloride (PAC), polyaluminium sulfate (PAS), bodied ferric sulfate (PFS) or poly-ferric chloride
(PFC) one kind in, the one kind of the inorganic metal salt for sodium chloride, in potassium chloride, the denitrifying bacteria activator into
It is divided into frerrous chloride, sodium acetate, peptone, yeast extract, glucose, sodium chloride, agar, potassium nitrate, mass ratio is successively during addition
