Description
Technical field
The present invention relates to a kind for the treatment of apparatus, specifically a kind of livestock and poultry farm natural pond liquid processing device.
Background technology
Livestock and poultry farm natural pond liquid is the product of breeding wastewater after Anaerobic Digestion, is wherein rich in ammonia, nitrogen, phosphorus, organic matter and high suspended matter, simultaneously also containing Ca
2+, Mg
2+deng many kinds of metal ions, be complicated inorganic, the organic waste water coexisted.Livestock and poultry farm natural pond liquid C/N is than low, and biodegradability is poor, directly discharges environmental pollution serious, and China is more nervous for the soil amount of natural pond liquid of directly dissolving.
It is nature process that natural pond, current pig farm liquid advanced treating approach mainly contains two: one, common are biological pond method and artificial swamp method; Biological pond method is a kind of tradition, cost-effective method of disposal, but also there are problems, as biological pond unreasonable structure, low, the ubiquity alluvial of purification load etc.Wetland variation method is rendered to soil by sewage and is often in water saturation state and growth has on the marshland of waterproof plant, sewage is flowed in a certain direction, a kind of land treatment systems technique under the synergy of waterproof plant and soil, sewage being purified.Wetland variation method has the advantages such as build and operating cost is low, effluent quality is good, easy and simple to handle, beautify the environment, but wetland floor space is large, for the place that soil is rare, is difficult to practical application.
Two is biochemical treatments, and common have RAT technique, BGO technique, BGGO technique, group technology etc.
A/O technique is by the pre-treatment of anaerobic hydrolysis technology for activated sludge, obtains, except degraded, also having certain denitrogenation dephosphorizing function except making organic pollution.This technique has good resistance to impact to entering organic matter of water change in concentration, good removal effect is had to the organic matter in Pig raising wastewater, ammonia nitrogen, but water outlet ammonia nitrogen concentration is still higher, mainly because the water inlet of low-carbon high-nitrogen causes the carbon source in system not enough, do not add carbon source in experimentation, therefore water outlet ammonia nitrogen does not reach desirable concentration.
SBR technique: sequencing batch active sludge (SBR) is a kind of activated sludge sewage disposal technology run by intermittent aerating mode, is widely used in Pig raising wastewater in recent years and directly processes.But when directly SBR technique being extended to process pig farm anaerobic digestion solution, treatment effeciency is lower, and COD clearance only has about 10%, NH
4 +-N clearance about 70%, and the job insecurity of the poor treatment system of process effluent quality, usefulness runs down.
SBBR technique: based on the sequencing batch biofilm reactor (SBBR) of sequencing batch active sludge (SBR); at reactor built with different fillers; make granular sludge; or installation filler makes activated sludge form biomembrane on filler in the reactor, more more efficient than SBR method.SBBR directly processes digested piggery wastewater, COD and NH
4 +-N removes unstable and effect is poor.
Group technology: when adopting traditional single method process pig farm anaerobic digestion solution, treatment effect is not ideal, and have fluctuation of service, Construction and operation cost higher, do not consider the shortcomings such as dephosphorization, be difficult to practice in engineering.For above problem, take A/O-MBR process integration, within the starting period of one month, carry out acclimation sludge by gradient of increasing concentration, after stable water outlet SCOD and ammonia nitrogen removal effect ideal, SCOD average removal rate is 70.6%, and ammonia nitrogen average removal rate is 99.4%.The TP of chemical flocculation part that can be removed, but in coagulation water outlet, carbon-nitrogen ratio is lower, and MBR lower than 30%, causes system comparatively large to the demand of basicity to the clearance of TN simultaneously, needs additionally to add medicament stablizing with keeping system.
Summary of the invention
The object of the present invention is to provide a kind of livestock and poultry farm natural pond liquid processing device, this natural pond liquid processing device by natural pond liquid through multistep treatment, natural pond liquid is again utilized after multiple times of filtration precipitation, and construction cost is low, floor space is little, achieves the harmless treatment of natural pond liquid, belongs to circular agriculture, recycling of water resource, achieves organic corruption, pathogenic microorganism, sick worm's ovum in the liquid of natural pond and removes.
The present invention solves the technical scheme that its technical problem takes: a kind of livestock and poultry farm natural pond liquid processing device, comprise the first treatment pond, second treatment pond, 3rd treatment pond and the 4th treatment pond, the first husky filter dam is provided with between the first treatment pond and the second treatment pond, the second husky filter dam is provided with between the second treatment pond and the 3rd treatment pond, the 3rd husky filter dam is provided with between the 3rd treatment pond and the 4th treatment pond, the bottom on the described first husky filter dam is provided with rubble and coarse sand, the bottom on the described second husky filter dam is provided with middle stone and medium sand, bottom microlith on the described the 3rd husky filter dam and fine sand, the first described treatment pond side connects tank for sewage gas, described first husky filter dam, the second husky filter dam and the 3rd husky filter dam are made up of inflow end bridge wall and outflow end bridge wall respectively, are provided with the sand filter mouth of band filter screen in the bottom of outflow end bridge wall.
