A kind of aquaculture wastewater processing system
Technical field
The invention belongs to sewage treatment field, more particularly to a kind of processing system of aquaculture wastewater.
Background technology
China is agricultural production big country, and in recent years, livestock and poultry cultivation scale constantly expands, and aquaculture wastewater is rich in nitrogen, phosphorus, organic Thing, directly discharge can impact environment.Livestock and poultry breeding scale pollution prevention ordinance points out that Animal Raising Zone should be built accordingly Feces of livestock and poultry, sewage treatment facility.Anaerobic digestion is the processing common method of feces of livestock and poultry, can not only realize livestock and poultry cultivation The harmless treatment of discarded object, can also provide biogas as clean energy resource.With the fast development of biogas engineering, largely Biogas slurry also produces therewith.It is also far from enough to qualified discharge but anaerobic digestion is merely capable of the pretreatment as initial stage.Poultry Fowl aquaculture wastewater/biogas slurry unit volume nutrient content is low, and storage, cost of transportation are higher, with the development of membrane separation technique, poultry Fowl aquaculture wastewater/biogas slurry film concentration technique becomes the hot spot of research.Livestock and poultry cultivation sewage/biogas slurry is after UF membrane, concentrate Liquid organic fertilizer can be configured, permeate can be with reuse.In practical applications, the expense of film account for whole system cost 5%~ 30%, the suspended matter, colloidal content in livestock and poultry cultivation sewage/biogas slurry are higher, can cause serious fouling membrane, it is concentrated in film Before, feed liquid is pre-processed.Although processing of the film process to aquaculture wastewater has good effect, long-play The processing cost that fouling membrane is brought is very high, this is difficult to bear for common farm.
The content of the invention
In view of the above problems, the present invention provides a kind of sewage disposal system of aquaculture wastewater, solves aquaculture wastewater and treats The technical problem that efficiency is low in journey, processing cost is high and takes up a large area.
The present invention provides a kind of sewage disposal system of aquaculture wastewater, it is characterised in that：It is single that it includes deamination pretreatment Member 1, tubular reactor unit 2 and wetland variation unit 3, above-mentioned processing unit are sequentially connected with；The deamination pretreatment unit Using baffle plate type deammoniation tower 11, treatment sewage is flowed from above to below from tower top, and in tower wall both sides, setting is staggered multiple Baffle plate 12, is provided with hot air apparatus 13 in the tower wall between baffle plate, is imported hot wind by hot air apparatus 13 each adjacent Baffle plate 12 between；Treatment sewage drops into the beginning of next baffle plate from the end of a upper baffle plate, so that shape Flowed into S-shaped；The density of setting of the baffle plate gradually increases from top to bottom.
The tubular reactor unit 2 is wholely set using Anaerobic Treatment unit 21 and tubular plate processing unit 22, preceding Section is Anaerobic Treatment unit, and rear end is tubular plate processing unit；The tubular reactor unit is provided with centre rotational axis 23, The surrounding of Anaerobic Treatment unit center rotation axis is provided with filler 24, centre rotational axis 23 drive filler 24 to rotate；In tubular type The centre rotational axis of pole plate processing unit are provided with blade 25, and the blade of rotary motion drives current to disturb up and down, the tubular type Reactor includes the positive plate 26 and minus plate 27 laid up and down, and positive plate 26 and minus plate 27 the fitting tube wall is set.
Preferably, the deamination pretreatment unit tower top is provided with air outlet, tower body a height of 3m, diameter 1m, baffle plate The spacing of end and tower wall is 0.3m；
Preferably, the long 5m of the tubular reactor, diameter 0.5m, wherein Anaerobic Treatment unit 21 and tubular plate processing unit 22 Respectively 2.5m, 2.5m；
The anode of the tubular plate processing unit is using platinum electrode, lead dioxide electrode；
Preferably, residence time 30-60 minute of deamination pretreatment unit.
Beneficial effects of the present invention：
（1）By the baffle plate being staggered, ensure the residence time of aquaculture wastewater, and the density of setting of baffle plate is not uniform , by reasonably setting the density of baffle plate to ensure that the efficiency of removal of ammonia and nitrogen, baffle(s) spacing, which is set, ensures ammonia as early as possible Reach tower top air outlet.
（2）Tubular reactor is wholely set, and centre rotational axis provide power for two processing units at the same time, can not only band Dynamic filler so that aging sludge comes off, and causes the sewage of tubular plate reactor to form disturbance, ensures wastewater electrochemical treatment place The high efficiency of reason.
（3）The present invention ensure that rural area by the combination of anaerobic baffled reaction device, tubular reactor and wetland variation The efficient process of aquaculture wastewater, especially suitable for the remote districts of sewage treatment plant's centralized processing are not implemented.
