Summary of the invention

The object of the invention is to do the excrement dirt of clear excrement diary farm for breeding stock less than 500 pasture types and produce row's feature and existing problems, a kind of livestock on hand less than 500 pasture types are provided to do the dirty integrated conduct method of clear excrement diary farm excrement, the method takes into account excrement dirt categorised collection, classification process, has seasonal adaptive faculty, necessarily storage and deep purifying ability, can realize the dirty integrated conduct method of comprehensive excrement of breeding combination.

Technical scheme of the present invention:

The dirty integrated conduct method of clear excrement diary farm excrement done by a kind of livestock on hand less than 500 pasture types, and step is as follows:

1) the equipment wash-down water first produced by milking parlour, treat that ground flushing water that the crowded Room produces, ox urine and a small amount of cow dung are by covered conduit collection in the Room, fall animal cilium and trifle through grid filtration after collection, then are transported to equalizing tank by hidden pipe;

2) anaerobic reactor is introduced in equalizing tank water outlet, by organic matter of fully degrading after the anaerobically fermenting process of anaerobic reactor, be ammonia nitrogen by nitrogenous for overwhelming majority organic matter transformation, the biogas of generation can be used as clean energy comprehensive utilization, and water outlet causes Aerobic Pond and carries out Air Exposure;

3) Aerobic Pond reaches the effect of deodorizing and deamination by aerobic treatment, breeding wastewater organic matter after Air Exposure obtains effective degraded, be stripped of the ammonia of free state, can be back to after disinfecting and treat that the crowded Room replaces clear water to rinse ground, the fine liquid manure resource that remaining water body will be applicable plant absorption and utilization, just can be directly used in plant husbandry by the proportioning that mixed filling pond is suitable and utilize;

4) solid manure collected of cowshed and playground is delivered directly to by night soil collector the material storage that heap excrement canopy utilizes as secondary resourceization, or as vermiculture matrix or directly stack retting become thoroughly decomposed fertilizer directly sell finally as fertilizer for plant husbandry.
