The wastewater treatment device is good in treatment effect, low in energy consumption, capable of recycling resources and creating economic benefits at the same time, and the like.

Description

A kind of livestock breeding wastewater treatment unit
Technical field
The utility model relates to water treatment device, can carry out the water treatment device of the different vegetables of water planting plantation after referring to especially the waste water that livestock and poultry cultivation produces processed.
Background technology
In recent years, along with the adjustment of China's structure of agricultural production and the propelling of agriculture industrialization, mass-producing, intensive livestock and poultry breeding industry are able to fast development, become most active growth point and important mainstay industry in China's rural economy.And answer the livestock and poultry cultivation requirement generally in the remote mountain areas, as around the waterhead area reservoir area.Large-scale cultivation produces the organic pollution materials such as a large amount of livestock and poultry fecalurias simultaneously, makes to pollute to concentrate, and is difficult to process serious environment pollution.Pollution from livestock and poultry has become the third-largest source of pollution after industrial pollution, domestic pollution, becomes the one of the main reasons of China's Rural Plane Source Pollution.If through effectively processing the in line water body that enters, easily do not cause the pollution of receiving water body and eutrophication occur.
From existing treatment technology and technique, exist following some shortcomings: 1, major part is taked the anaerobism coagulation, has subdued most COD, but is not very high to the clearance of nitrogen, phosphorus.2. the cost of often processing under the aerobic treatment process condition is very high, and livestock and poultry cultivation generally is difficult to bear expensive processing costs as traditional poor benefit industry.3. nitrogen, phosphor resource can not fully be recycled, and enter the easy body eutrophication of water body.
Summary of the invention
The utility model overcomes the problem that prior art exists, and provides that a kind for the treatment of effect is good, energy consumption is low and accomplishes that resource reclaims the novel livestock breeding wastewater treatment unit of creating simultaneously economic benefit etc.
Realize above-mentioned purpose, the utility model adopts following technical scheme, a kind of livestock breeding wastewater treatment unit, it is characterized in that: include and reconcile pond, anaerobism EGSB reactor, intermediate sedimentation pond and multifunctional bio filter tower, wherein reconciling the pond is connected on the anaerobism EGSB reactor by pipeline, be connected with pipeline between anaerobism EGSB reactor and the intermediate sedimentation pond, connecting tube between intermediate sedimentation pond and the multifunctional bio filter tower, the water outlet of multifunctional bio filter tower is divided into two-way, wherein one the tunnel be connected on the water-in of reconciling the pond, another road is connected with the extraneous end that utilizes.
Further setting of the present utility model is: described multifunctional bio filter tower includes successively from top to bottom the nitrobacteria layer, inhales the ammonia nitrogen layer and inhales phosphorus functional layer, the spacing of interval 35-45cm between each layer; Be connected with pump on the pipeline of described conciliation pond and anaerobism EGSB reactor, be connected with pump on the pipeline of described intermediate sedimentation pond and multifunctional bio filter tower.
The utility model adopts such scheme, reaches following effect: overcome the deficiency of conventional processes, on denitrogenation dephosphorizing, obtained new breakthrough especially.Avoid simultaneously the processing costs of great number, and produced economic benefit.In conjunction with the present situation of present livestock and poultry cultivation, this device has larger application prospect.
Below in conjunction with accompanying drawing the utility model is described further.
Description of drawings
Fig. 1 is the principle schematic of the utility model embodiment.
Embodiment
As shown in Figure 1, a kind of livestock breeding wastewater treatment unit, livestock breeding wastewater is through equalizing tank 1, enter anaerobism EGSB reactor 2 by the pump lifting, anaerobic effluent enters intermediate sedimentation pond 3, then enters multifunctional bio filter tower 4, and two-way is divided in multifunctional bio filter tower 4 water parts, one the tunnel is back to equalizing tank 1, and another road enters into oxidation pond water planting base 5.
Certain plant's waste water: influent COD cr=3045 ~ 6265mg/L, NH4-N=70 ~ 217 mg/L, TN=89 ~ 318%, TP=42 ~ 78 mg/L.
Breeding wastewater at first passes through anaerobic treatment, and the volume of design is 6 cubic metres, and hydraulic detention time is 1 day, and at the multi-functional filter tower of process, hydraulic load enters oxidation pond water planting base 5 at last at 1.2m3m-2d-1, hydraulic detention time 7 days.Through efficient anaerobic EGSB reactor, the clearance of CODcr, TP, TN distributes and reaches 83%, 50%, 42%.CODcr and TP, TN can have effectively been cleared up.
The different functional stuffing of multifunctional bio filter tower 4 interior fillings, and reserve the space of 40cm between the filtering layer.Using immobilized nitrifying bacteria is filled by the superiors 41, takes calcium-alginate-immobilized embedding nitrobacteria.It is 3 ~ 5cm zeolite and 900 ℃ of section calcinings 1 hour that diameter is chosen in stage casing 42, improves the capacity that it inhales ammonia nitrogen.Hypomere 43 is for inhaling the phosphorus functional stuffing, and taking laterite is aggregate, adds cement, calcium oxide, aluminium powder and carries out moulding and calcining, and its diameter control is 8 ~ 10cm.Anaerobic effluent promotes through pump, from the top water inlet of multi-functional filter tower, bottom water outlet.Water outlet directly enters oxidation pond water planting base 5.Through multi-functional filter tower, CODcr, TP, NH4-N, TN have further cut down respectively 62%, 93%, 95%, 70%.
Oxidation pond design hydraulic detention time is 7 days, and water surface water planting vegetables fraction of coverage is about 50%.Final outflow water: water outlet CODcr=31 ~ 84mg/L, NH4-N=11 ~ 33mg/L, TP=0.5 ~ 5 mg/L, TN=21 ~ 54mg/L.Obtain simultaneously certain economic benefit.
