2) waste material inside anaerobic reactor is sent into solid-liquid separating machine, the solid and liquid detached, solid conduct Composting material, liquid enter regulating reservoir;
3) flocculant is added into regulating reservoir, stands 2-3 days;
4) by regulating reservoir at the middle and upper levels Liquid extracting to biological reaction pool, biological reaction pool bottom is equipped with Nutrition Soil and mistake Filter medium.
Preferential, grid is revolution rake teeth type mechanical grille in the step 1), and grizzly bar spacing is 40mm.
Preferential, solid-liquid separating machine is internally provided with high density sieve in the step 2), and the high density sieve screen number is 60-100 mesh.
Preferential, flocculant is magnesium hydroxide and polyacrylamide according to mass ratio 3 in the step 3):1 mixes.
Preferential, Nutrition Soil upper surface kind is implanted with one or more in reed or canna in the step 4), and biology is anti- Being launched inside Ying Chi has chlorella.
Preferential, filter medium is cobble and quartz sand in mass ratio 4 in the step 4):3 mix.
(3) advantageous effect
1, the solid and liquid that the waste water of dairy cow farm is isolated through solid-liquid separating machine, solid can be used as composting material, It is delivered directly to heap excrement canopy by night soil collector and is used as the material storage that secondary resource utilizes, or the matrix as vermiculture Or directly the decomposed fertilizer of stack retting is directly sold eventually as fertilizer for planting industry, in remaining wash under content of organics Drop, to alleviate biodegradable burden, convenient for handling in next step.
2, the flocculant in raw material of the present invention is mixed by aluminium hydroxide and polyacrylamide, as inorganic flocculating agent, Polyacrylamide is as organic flocculant, so as to efficiently remove the nutriments such as Organic Pollutants in Wastewater and nitrogen phosphorus, from And water outlet can be up to standard, meets discharge standard and agriculture fills standard.
3, Nutrition Soil upper surface kind is implanted with one or more in reed or canna, and the root absorption of reed or canna is useless Phosphate anion in water, it is fresh water algae that the dispensing of biological reaction pool inside, which has chlorella, chlorella, is suitble to train in breeding wastewater It supports;And chlorella can carry out mixotrophic growth, and the elements such as nitrogen, the phosphorus in breeding wastewater can have both been utilized by photosynthesis It realizes photoautotrophy, and directly can carry out heterotrophism using the organic substance in breeding wastewater, breeding wastewater can be removed in this way Nitrogen, phosphorus in middle inorganic matter, and nitrogen, phosphorus in organic matter can be removed, so as to remove comprehensively the nitrogen in the machine object in waste water, Phosphorus.
