Background technology
In the production of Large-scale pig farm, every day will discharge a large amount of Pig farm wastewater.Pig farm wastewater mainly rinses the sewage of discharging after pig house with water, to mainly contain in the ight soil of pig, remaining feed, pig house the solid substances such as rubbish in Pig farm wastewater.For the pig farm of delivering more than ten thousand year for sale, the Pig farm wastewater that every day discharges can reach 150 ~ 250 M 3, wherein pig manure more than 20 ton.Pig farm wastewater belongs to the waste water that solid substance is more, organic concentration is high.Pig farm wastewater, without process, can not directly discharge.
In order to Large-scale pig farm sewage can be allowed to reach emission standard, Large-scale pig farm commonly uses A/O method process high concentrated organic wastewater device process Pig farm wastewater.
A/O method is the common method with biochemical process process high concentrated organic wastewater.A/O is the abbreviation of Anoxic/Oxic, and A/O method is also referred to as anaerobic and aerobic process, and A/O method has forward and backward two sections, and A is anaerobic process section, and O is aerobic method section.
The anaerobic pond that A/O method process high concentrated organic wastewater device has order to be connected, intermediate sedimentation pond, contact-oxidation pool, final settling tanks and intermittent type aerobic aeration pond, the lower outlet in intermediate sedimentation pond, final settling tanks and intermittent type aerobic aeration pond also order is connected with concentration basin and pressure filter, final settling tanks and be connected with reflux line between contact-oxidation pool and anaerobic pond, have inlet mouth at the bottom of the pond in aerobic aeration pond and intermittent type aerobic aeration pond, inlet mouth is connected with gas blower.
Because in Pig farm wastewater, solid substance is more, solid substance device in removal sewage to be had before with A/O method process high concentrated organic wastewater device, remove that solid substance device in sewage has connected grating tank, detritus pool, equalizing tank, the tower that blows off, slanted screen and front settling tank, detritus pool is connected with crowded excrement machine, and the lower outlet order of front settling tank is connected with concentration basin and pressure filter.
As described above, Large-scale pig farm sewage device has solid substance device and A/O method process high concentrated organic wastewater device in connected removal sewage.
In prior art; in the A/O method process high concentrated organic wastewater device of Large-scale pig farm sewage device; the Chi Kou of anaerobic pond is unlimited, and the biogas that sewage produces carry out anaerobic reaction in anaerobic pond after is discharged in surrounding environment naturally, and anaerobic pond does not have warming apparatus.When temperature is lower, sewage can not carry out anaerobic reaction in anaerobic pond, and this Large-scale pig farm sewage device can not normally run in the cold district that temperature is lower.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, proposes a kind of at temperature lower ground cold district, the district Large-scale pig farm waste disposal plant that can normally run.
The utility model realizes with the following method.
Cold district Large-scale pig farm waste disposal plant has solid substance device and A/O method process high concentrated organic wastewater device in connected removal sewage,
Remove that solid substance device in sewage has connected grating tank, detritus pool, equalizing tank, the tower that blows off, slanted screen and front settling tank, under detritus pool, outlet is connected with crowded excrement machine, and the lower outlet order of front settling tank is connected with concentration basin and pressure filter,
The anaerobic pond that A/O method process high concentrated organic wastewater device has order to be connected, intermediate sedimentation pond, contact-oxidation pool, final settling tanks and intermittent type aerobic aeration pond, the lower outlet order in intermediate sedimentation pond, final settling tanks and intermittent type aerobic aeration pond is connected with concentration basin and pressure filter, final settling tanks and be connected with reflux line between contact-oxidation pool and anaerobic pond, inlet mouth is had at the bottom of the pond in contact-oxidation pool and intermittent type aerobic aeration pond, inlet mouth is connected with gas blower
The Chi Kou of anaerobic pond has seal bootr, and seal bootr has methane outlet, has interchanger in anaerobic pond,
Anaerobic pond is connected with coal and the dual-purpose anti-burning water-heating boiler of biogas, has biogas burner in the burner hearth of coal and the dual-purpose anti-burning water-heating boiler of biogas,
Coal and the dual-purpose anti-burning water-heating boiler of biogas have cooling water inlet, hot water outlet and biogas import,
Methane outlet on anaerobic pond seal bootr is connected with the biogas import of the dual-purpose anti-burning water-heating boiler of coal and biogas, coal is connected with the entrance of interchanger in anaerobic pond with the hot water outlet of the dual-purpose anti-burning water-heating boiler of biogas, and coal is connected with the outlet of interchanger in anaerobic pond with the cooling water inlet of the dual-purpose anti-burning water-heating boiler of biogas.
During use, allow Pig farm wastewater be introduced into grating tank, isolate larger solid substance through grating tank, sewage enters detritus pool, isolatedly enters crowded excrement machine with ight soil with main larger solid substance and discharges,
In the sewage of equalizing tank, drop into milk of lime, ammonium nitrogen in sewage is converted into free state ammonia, sewage is removed in sewage after free state ammonia after the tower that blows off, and enters anaerobic pond by slanted screen and front settling tank,
The premenstrual settling tank solid substance isolated in sewage enters concentration basin and pressure filter is discharged,
Sewage produces anaerobic sludge at anaerobic pond after anaerobic reaction, after isolating anaerobic sludge by intermediate sedimentation pond, sewage enters contact-oxidation pool, sewage reacts and produces biogas in anaerobic pond, and the intermediate sedimentation pond isolated solid substance of settling tank enters concentration basin and pressure filter is discharged
Biogas enters coal and the dual-purpose anti-burning water-heating boiler combustion of biogas, the hot water produced is by the interchanger heating anaerobic pond in anaerobic pond, allow anaerobic pond still can remain on the temperature carrying out anaerobic reaction when envrionment temperature is lower, when the utility model brings into operation and when because anaerobic reaction is abnormal not causing biogas deficiency, need with the fuel of coal as coal and the dual-purpose anti-burning water-heating boiler of biogas, after anaerobic pond normally runs, the methane quantity of generation just can meet the temperature keeping anaerobic pond
Sewage produces active sludge at contact-oxidation pool after aerobic reaction, sewage enters intermittent type aerobic aeration pond after isolating active sludge by final settling tanks, most of activated sludge is discharged through concentration basin and pressure filter, and small part active sludge is through turning back to anaerobic pond and contact-oxidation pool
Sewage reaches emission standard in intermittent type aerobic aeration pond after the multiple action-reaction such as aerobic, anoxic, anaerobism and precipitation and degree of depth biological treatment purification, sewage produces a small amount of mud after the process of intermittent type aerobic aeration pond, and a small amount of mud is discharged through concentration basin and pressure filter.
Interchanger is had in anaerobic pond of the present utility model, the Chi Kou of anaerobic pond has seal bootr, seal bootr there is methane outlet, the coal that the utility model is connected with anaerobic pond in addition and the dual-purpose anti-burning water-heating boiler of biogas, during use, the collecting methane produced when anaerobic pond can be run, the heat produced with biogas combustion heating anaerobic pond, makes the utility model can normally run in cold district.
