Description
Technical field
The present invention relates to technical field of waste water processing, and in particular to a kind of processing method of milk cattle cultivating waste water.
Background technology
Large-scale cultivation development speed in China's is very fast in recent years, but the pollutions such as fecaluria processing, stain disease processing and solid waste
Improvement level is but not kept pace with the cultivation speed of development, certain cost has been paid in environmental problem thus, with farm
The expansion of scale, fecaluria, sewage quantity also accordingly increase, and the centralization of fecaluria, sewage causes environmental pressure can't bear the heavy load, much
Steal row, illegal disposition in side so that farm's pollution treatment becomes the one of the major reasons for restricting cultivation scale development.Dairy waste water master
There is following feature:Organic matter, nitrogen and phosphorus content are high, and water is big and temperature is relatively low.The uniqueness of dairy waste water increases
Intractability is difficult processing up to standard using existing processing method.The processing method of Cattle Wastewater includes mainly at anaerobism at present
Reason method, Aerobic treatment method and anaerobic-aerobic combination treatment method.Although anaerobic treatment method can handle high concentration milk
Cattle farm waste water, but aqueous concentration is still very high after Anaerobic Treatment, can not qualified discharge, and with stink, influence ring around
Border.
Invention content

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.
