Embodiment 1

[0037] A biological nest material, which is composed of a long spiral ribbon structure formed by forward and reverse folding of an arched structure 14 in a cylindrical helicoid. The central angle 15 of the arched structure is 60 ° (as image 3 shown). Described cylindrical helicoid width is 1.5cm, and thickness is 0.15mm (as Figure 4 shown). The biological nest material is made of PVC material, and the specific surface area is 3100m 2 / m 3 , the specific gravity is 1.02.

Embodiment 2

[0039] like figure 1Shown, a kind of livestock and poultry farm wastewater treatment system, it comprises sedimentation tank 1, regulating tank 2, anaerobic reactor 3, effluent collection tank 4, sand type effluent treatment tank 5 and follow-up treatment tank 6, sedimentation tank 1 and Regulating tank 2, regulating tank 2 and anaerobic reactor 3, anaerobic reactor and effluent collection tank 4, effluent collecting tank 4 and sand-type effluent treatment tank 5, sand-type effluent treatment tank 5 and subsequent treatment tank 6 are connected in sequence , the anaerobic reactor is made up of two biological nest anaerobic reactors 3, and the water outlet 13 of the previous biological nest anaerobic reactor communicates with the water inlet 10 of the latter biological nest anaerobic reactor through the connecting pipe 12, as figure 2 Shown; Biological nest anaerobic reactor 3 comprises main body anaerobic fermentation tank 7 and biological nest device 9, two biological nest d...

Embodiment 3

[0051] Wastewater treatment of 2,000 pig farms:

[0052] As the livestock and poultry farm waste water treatment system described in embodiment 2, the difference is:

[0053] A farm with 2,000 pigs in stock produces 14m of pen flushing water and pig urine every day 3 , the specific device design and method are as follows:

[0054] (1) Sedimentation tank 1 is made of brick concrete with a volume of 8m 3 , the size is length × width × height = 2.0m × 2.0m × 2.0m;

[0055] (2) The adjustment pool 2 is made of brick concrete with a volume of 15m 3 , the size is length × width × height = 2.0m × 3.0m × 2.5m;

[0056] (3) The biological nest anaerobic reactor is a glass fiber reinforced plastic structure, the design hydraulic retention time is 15h, and the design volume of each reactor is 4.5m 3 ;

[0057] (4) According to the amount of treated wastewater, the effluent of the bio-nest anaerobic reactor is 13m per day 3 , the volume of the water collection tank 4 is designed to...

Abstract

The invention relates to a high-efficiency waste water treatment system for a nursery, belonging to the technical field of waste water treatment. A waste water treatment system for a livestock and poultry nursery comprises a settling tank, a conditioning tank, an anaerobic reactor, an outlet water collecting tank, a sand type outlet water treating tank and a post-treating tank which are connected in order, wherein the anaerobic reactor is composed of a secondary biological nest anaerobic reactor, the biological nest anaerobic reactor comprises an anaerobic fermenter main body and a biological nest device, the biological nest device is arranged in the anaerobic fermenter main body, the lower part of the side wall of the anaerobic fermenter main body is provided with a water inlet, the upper part of the side wall of the anaerobic fermenter main body is provided with a water outlet and a sample connection, and the top of the anaerobic fermenter main body is provided with a gas outlet; and the biological nest device is of a hollow cylindrical structure, the upper wall and the lower wall of the biological nest device are provided with holes, and biological nest materials are filled in the biological nest device. The invention has the characteristics of high treating efficiency, small occupied area, low construction cost, convenient maintenance and operation and the like.

Description

technical field [0001] The invention relates to a high-efficiency farm wastewater treatment system, which belongs to the technical field of wastewater treatment. Background technique [0002] In recent years, with the development of the economy and the improvement of people's living standards, the demand for animal husbandry products has also continued to increase, which has promoted the development of my country's animal husbandry industry in the direction of scale and intensification. According to the survey, most farms in China currently adopt the method of dry manure cleaning, and most of the livestock and poultry breeding wastewater produced is wastewater such as washing pens and houses. The general index is: COD Cr =2000~12000mg / L, BOD 5 =1000~5000mg / L, TSS=1000~8000mg / L, NH 3 - -N=30~220mg / L. These wastewaters are directly discharged into rivers, lakes and reservoirs with rainwater, making the water black and smelly; seeping into the ground for a long time, increa...
