Embodiment
With reference to specific embodiment, the present invention will be further described.
As shown in figure 1, a kind of livestock and poultry cultivation sewage disposal zero-emission and organic fertilizer recovery system, including following multiple systems
System：For carrying out the solid-liquid separation system of initial gross separation, for removing the pre- of larger particles debris to solid in sewage and liquid
Filtration system, for further remove smaller particle debris tubular ultra-filtration membrane system and for multistage filtering and the multistage of concentration
RO systems.
Livestock and poultry cultivation excrement and urine waste is after separation of solid and liquid obtains solid organic fertilizer and methane-generating pit pretreatment, biogas slurry（Cross
Filtrate）It is collected in sewage collecting pool, the sewage collecting pool is in addition to sewage is collected, also with regulation stabilizing water quantity, equal Hengshui
Matter etc. is acted on.Provided with elevator pump, fluid level controller etc. in sewage collecting pool, the fluid level controller can use liquid-level floater etc.,
The water level of sewage collecting pool is monitored by fluid level controller, and then automatically controls the opening and closing of elevator pump.In collecting pit
Sewage be pumped to the water inlet of prefilter by elevator pump, sewage collecting pool can be also arranged on to higher position, according to
Make sewage self-flowing to the water inlet of prefilter by gravity, the sewage after having been filtered through prefilter enters the first collecting vessel,
The delivery port of first collecting vessel is connected with the water inlet of tubular ultra-filtration membrane, and can remove particle diameter here by tubular ultra-filtration membrane is more than 10
μm debris（Such as suspension, insoluble colloid）Afterwards, by the filtered water collection filtered in the second collecting vessel.Wherein, in advance
The debris of larger particles can be filtered equipped with 0.5~0.8mm filter screens in filter, prefilter is set before tubular ultra-filtration membrane
Effect be remove sewage in larger particles debris to avoid blocking or damage tubular ultra-filtration membrane, i.e., as the guarantor of tubular ultra-filtration membrane
Pacify filter.
It is after prefilter using the advantage of tubular ultra-filtration membrane：It is fairly simple for the pre-processing requirements of material, liquid,
Need to only be removed through 0.5~0.8mm filter screens has the gritty matter directly damaged to enter tubular membrane unit to film, due to pretreatment letter
Single-unit about input cost, has saved operating cost.For processing high solid material, high concentration material, liquid, tubular membrane shows non-
All abilities, are not afraid of blocking, are not likely to produce concentration polarization, and can adjust flow velocity on a large scale, it is ensured that its disposal ability.
Hereafter, the water quality after being handled for guarantee can reach sewage discharge national standard, set many after tubular ultra-filtration membrane
Level RO systems, the setting of series can be depending on actual demand, and the present invention is by taking two-stage RO systems and a DTRO systems as an example, specifically such as
Under：
The delivery port of second collecting vessel is connected with the water inlet of one-level RO systems, the delivery port of the 3rd collecting vessel and two grades of RO systems
The water inlet of system is connected, and after the filter water through one-level RO system outputs enters the 3rd collecting vessel, enters back into two grades of RO systems and enters
Row processing so that its effluent quality is up to state standards《Urban sewage reutilization urban reclaimed water water quality》（GB/T 18920-
2002）, the filtered water collection handled through two grades of RO systems can carry out after disinfection by ultraviolet light reclaimed water to it and return in scuttlebutt
With available for poultry colony house, ground, road, vehicle, construction, urban afforestation, fire-fighting etc. is rinsed, improving to original dirt
The utilization rate of water.
Through one-level RO systems handle after concentrate be stored in the 4th collecting vessel, after DTRO systems can be pumped into by elevator pump
The water inlet of system, or water inlet by the delivery port of the 4th collecting vessel directly with DTRO systems are connected, it is preferred that through DTRO systems
Filter water after system processing enters the 3rd collecting vessel to improve the utilization rate to water, then handled by two grades of RO systems with true
The water stabilization for protecting water outlet is reliable, and the concentrate after being handled through DTRO systems is stored in the 5th collecting vessel, can be further by its
Dehydration concentration is fabricated to Liquid organic fertilizer, and fertilizer efficiency is lifted by increasing the nutrient density of Liquid organic fertilizer.Can by this mode
Nutrient in sewage is highly concentrated with recycling.
In addition, the producing water ratio to improve one-level RO systems, the concentrate after two grades of RO systems processing is back to the second receipts
Collect in bucket, be recycled for the processing of the systems such as one-level RO, two grades of RO and DTRO, water quality after being handled with further raising and to dirt
The recycling of nutrient in water.
In addition, can also be in one, Duo Gehuo in the first collecting vessel, the second collecting vessel, the 3rd collecting vessel, the 4th collecting vessel
Elevator pump is provided with whole collecting vessels, can be by elevator pump by sewage, filter water or concentrate pump to corresponding next stage system
The water inlet of system, can be set each system in the same horizontal line using such a mode so that overall to seem more attractive in appearance；Also
Fluid level controller can be provided with, the fluid level controller can monitor each collecting vessel by fluid level controller using liquid-level floater etc.
In water level, and then automatically control the opening and closing of elevator pump.
For the further automaticity for improving whole system and saving human cost, the present invention, which is removed, to be controlled using manual
System is outer, can also be provided with a control system, remaining all system can be automatically controlled, to realize the automatic fortune of whole system
OK.
In addition, being respectively provided between scuttlebutt and tubular ultra-filtration membrane system, one-level RO systems, two grades of RO systems and DTRO systems
One return duct, when tubular ultra-filtration membrane system, one-level RO systems, two grades of RO systems and DTRO systems are out of service and sewage is emptied
When, the filter water in scuttlebutt will be back to each system by corresponding return duct and it will be cleaned.
Using technical scheme, separation of solid and liquid can be carried out to livestock and poultry cultivation excrement and urine waste and obtain solid organic fertilizer
Material, then after prefilter and tubular ultra-filtration membrane processing, by one-level RO systems, two grades of RO systems, DTRO systems etc. mutually
Cooperation meets the standard of national pollution emission standard and urban reclaimed water water quality to obtain, and the liquid that can also obtain higher concentration is organic
Fertilizer, and then realize the zero-emission of the sewage, it is to avoid environment is polluted, also the nutrient of sewage Liquid organic fertilizer can be condensed into
To recycle, the utilization rate to sewage is improved, and the automatic running of whole system can be realized and each system is carried out automatic
Cleaning, reduces cost of labor.
Although specifically showing and describing the present invention with reference to preferred embodiment, those skilled in the art should be bright
In vain, do not departing from the spirit and scope of the present invention that appended claims are limited, in the form and details to this hair
It is bright to make a variety of changes, it is protection scope of the present invention.
