Description
Technical field
The invention belongs to technical field of sewage, be particularly suitable for slaughtering industry it is a kind of remove it is highly concentrated in slaughtering wastewater
The wastewater treatment equipment of degree ammonia nitrogen.
Background technology
The production waste water of slaughtering industry due to containing substantial amounts of feces, blood stains, fat, protein, its not only biochemical oxygen demand
Amount and BOD are high, and this kind of waste water Jing natural fermentations can more produce the ammonia nitrogen compound of a large amount of difficult neutralizings, this kind of height
The a large amount of directly outer rows of ammonia nitrogen eutrophy waste water, will produce serious harm, make natural water eutrophication and disappear to natural environment
Dissolved oxygen in water consumption, causes that water body is smelly, mosquitos and flies grows, pathophoresiss, not only endangers human and livestock health, while can also promote river
Algal bloom in river lake and ocean water, induces " red tide ", directly endangers the living environment of Fish and other organisms in water,
Slaughtering wastewater has become a kind of high density pollution source of serious harm natural environment.At present, the process of slaughtering wastewater is typically adopted
Detest nitrogen-aerobic traditional activated sludge process and derived from by which oxidation ditch, the technique such as SBR, AB, A2O, but this kind of technique tool
There are big floor space, complex process, equipment investment and operating cost height, process time length, effluent quality are unstable, particularly ammonia
Nitrogen poor removal effect, has had a strong impact on the qualified discharge of slaughtering wastewater.
The content of the invention
The purpose of the present invention is to solve above-mentioned the deficiencies in the prior art, there is provided highly concentrated in a kind of effectively removal slaughtering wastewater
The processing meanss of degree ammonia nitrogen, can overcome the shortcoming of above-mentioned method of wastewater treatment, and it has a simple structure, take up an area less, reduced investment,
High treating effect, operating cost are low, have higher clearance to ammonia nitrogen compound, are very suitable for current slaughtering industry high-concentration waste
The needs of water process.
The present invention is the round can type wastewater treatment equipment made by materials such as steel plate, fiberglass or brick mixed buildings,
In processing meanss, Inner electrolysis reaction zone, coagulating area and perpendicular stream settling section are separated into by circumference wallboard and base plate, in interior electricity
In solution reaction zone, device has ferrum-charcoal electrolysis filler, and coagulating area middle device has air stripping mixing tube, and air stripping mixing tube is extended to
There is micro-hole aerator in the lower end centre position in coagulating area, device, by pressing wind aeration, waste water lifting are entered in mixing tube,
Play and wash away stirring action, coagulating area and perpendicular stream settling section bottom are connected, and water inlet, water outlet are provided with the top of processing meanss
Mouth, transom and flocculant grug feeding jar, under flocculant grug feeding jar, end device has tube for transfusion, and tube for transfusion is connected to mixing tube lower end,
By fluid-delivery valve control flocculation added amount of chemical, slaughter hall slaughtering wastewater out Jing oil removal every slag bath process after from waste water
Water inlet at the top of reason device is pumped into Inner electrolysis reaction zone, and certain ratio is mainly pressed by iron filings and activated carbon in Inner electrolysis reaction zone
Example filling is formed, and when being immersed in waste water, due to the difference in Electrode Potential between ferrum and carbon, constitutes countless micro- electricity
The low ferrum in pond, wherein current potential becomes anode, and the high carbon of current potential becomes negative electrode, and waste water is by the ferrum carbon mix in light electrolysis tower
When, form a huge interior battery, blood stains, fat, protein in slaughtering wastewater etc. and electroreduction occurs in interior battery
Reaction, in waste water, organic molecule carries out de- steady, rupture under electric field action, removes hematochrome rapidly, while the fat in waste water
The materials such as fat, protein also fail to microbe conversion into before ammonia nitrogen at which, and molecular structure has cracked change, is effectively prevented from ammonia nitrogen
Produce.Test shows, waste water after Inner electrolysis reaction, biodegradability brings up to 0.70 by original 0.45～0.50～
0.75.This is because the material such as macromole such as haemachrome, fat, protein is after Inner electrolysis process, due to nascent state material
The redox of Fe2+, H, macromolecular substances resolve into the intermediate of small molecule, are playing decolorization and are reducing COD's
Meanwhile, also destroy fat, Rumen protein fermentation generate ammonia nitrogen material conditions, waste water in internal electric field abundant breakdown of emulsion, take off be surely
Follow-up coagulating treatment creates advantage.Water outlet Jing Inner electrolysis reaction zone bottom is processed under the effect of aeration ascending air, is entered
Enter mixing tube, while opening medication infusion valve at the top of processing meanss, flocculant is transported to into mixing tube, in mixing tube with
The stirring of washing away for rising air-flow is sufficiently mixed, is flocculated with waste water, then enters perpendicular stream settling section from coagulating area bottom, in coagulation
Reaction zone is formed in the perpendicular stream settling section that the waste water of a large amount of floccules enters to static state from dynamic coagulating area, moment point
Layer, floccule body constantly compress sinking, and supernatant is constantly arranged from outside the outlet on top.Through the operation in one period, with wadding
Solidifying and suspended solid particle constantly sinks to accumulating, and makes clear layer narrow, and easily causing floccule body channelling affects effluent quality, therefore fixed
Phase opens perpendicular stream settling section blowoff valve, precipitation dope is suitably drained, to keep appropriate clarification layer height.
