Embodiment Construction
[0017] Below in conjunction with accompanying drawing, specific embodiment of the present invention is described in further detail:
[0018] Such as figure 1 As shown, the dairy farm 1 of the dairy farm sewage treatment and comprehensive utilization system designed in the present invention adopts the sewage discharge method combining dry manure and flushing water. At present, there are generally three ways for the sewage discharge of dairy farm 1, dry manure cleaning, flushing water and foaming manure. The present invention chooses to use the combination of dry cleaning manure and flushing water to discharge sewage. On the other hand, it also effectively reduces the feces content in the sewage, which reduces the difficulty of sewage treatment.
[0019] The treatment and comprehensive utilization system includes a grit chamber 2, a sewage collection pond 3, an anaerobic fermentation pond 4, an SBR pond 5, an artificial wetland 7 and a gas storage tank 8, and the grit chamber ...

The invention provides a new dairy farm sewage treatment and comprehensive utilization system. The dairy farm adopts a sewage discharge method combining dry manure cleaning and flushing water; the treatment system includes a grit chamber, a sewage collection tank, an anaerobic fermentation tank, SBR tank, artificial wetland and gas storage tank, the grit chamber is connected to the sewage discharge groove of the dairy farm, and a grid is arranged at the entrance of the grit chamber, and the sewage collection tank is connected to the grit chamber outlet through the groove, and the sewage collection tank The sewage in the tank is discharged into the anaerobic fermentation tank through the pipeline. The anaerobic fermentation tank is equipped with an exhaust pipe and a drain pipe. The exhaust pipe is connected to the gas storage tank, the drain pipe is connected to the SBR pool, and the SBR pool is connected to the constructed wetland through a pipeline or a trench. In the treatment system, the sewage treated by the artificial wetland is used for production irrigation or directly discharged; the treatment system also includes a dry manure treatment mechanism, which is used to treat dry manure and solid waste generated in the sewage collection tank. The invention has high resource utilization rate, can save water to the greatest extent, has excellent sewage treatment effect and good economic benefit.
Description
technical field [0001] The invention relates to the field of agriculture, in particular to a dairy farm sewage treatment and comprehensive utilization system. Background technique [0002] In recent years, large-scale breeding of dairy cows has become a trend. With the rapid development of dairy farming, a large amount of breeding sewage has been produced. The wastewater from dairy farms is mainly composed of manure water, flushing water, etc., with high concentration and high suspended solids. At the same time, the sewage also has the characteristics of "three highs" such as high COD, high NH3-N and high pathogenic microorganisms. The treatment of the above-mentioned sewage not only brings huge management pressure to the owners, but also poses a serious threat to the environment. Taking a dairy farm with 5,000 cows as an example, each cow produces about 150L of sewage a day, and the daily amount of sewage to be treated reaches 750 tons. [0003] At present, most dairy far...
