Pool volume is 5 ~ 6 times of setting pot 2.Using air blast micro-pore aeration mode, SBR ponds can be controlled by adjusting aeration time
5 dissolved oxygen concentrations, make aerobic-anoxic alternately, and in favor of the removal to ammonia nitrogen, preferably 6h is a cycle of operation.
The disinfectant of the sterilization pool 6 selects NaClO, and using intermittent drainage mode, dischargeable capacity is setting pot 2
4 ~ 5 times.Sterilization pool 6 is mainly that the sewage after handling SBR ponds 5 is carried out disinfection and sterilized, and kills coliform therein
Deng pathogenic microorganisms.
The area of the artificial swamp 7 is calculated as 2.5hm with 5000 cow head scales2, the area plantation jade of wetland 80%
Rice or rye grass, remaining plantation taro, sewage artificial swamp demurrage in 3d.Inventor designs artificial swamp 7 to handle
Follow-up sewage, mainly consideration purify sewage with the ecosystem, while improving purification efficiency, moreover it is possible to obtain wholesale as far as possible
Economic well-being of workers and staff.For this reason, the corn that the fertilizer requirement of the suitable local plantation of selection is big, well developed root system, biomass are big, rye grass and
Taro, which carries out the plantation of timesharing subregion, to be advisable.The plant of corn and rye grass as the crop rotation of winter in summer, can meet cattle farm to greenfeed
Demand, biogas slurry passes through corn（Or rye grass）Ground flows into taro after coming out, milpa and taro whole furrow ditch, biogas slurry exist
Flow furrow ditch intermittent.Artificial swamp area design：By about 2.5hm2Field is divided into 3 pieces, two pieces of 1hm2Be used for plant
Corn or rye grass, remaining 0.5hm2For planting taro.
The dry cleaning up excrement processing mechanism 10 is preferably dry cleaning up excrement drying mechanism, for will be produced in dry cleaning up excrement and sump 3
Raw solid slag is used as planting edible mushroom raw material after drying.The waste residue of dry cleaning up excrement and sump 3, carries out solarization etc. after collection
Drying process, the cow dung dried are good planting edible mushroom raw materials, it " is turned waste into wealth ", can further increase warp after sale
Ji benefit.
The core of the present invention is that the blowdown mode of cattle farm is combined as using dry cleaning up excrement and flushing water, with anaerobism, aerobic
Sewage disposal is carried out to reach water-saving, the high level of resources utilization and the mesh taken into account of environmental protection with reference to the mode of artificial swamp Ecological Disposal
, therefore, protection scope of the present invention is not limited only to above-described embodiment, any using above-mentioned on the basis of the principle of the invention
The change or deformation of mechanism, belong to protection scope of the present invention.
