Description

Imitative forest surface ecosystems process the dirty method and device simultaneously producing fertilizer of excrement

Technical field

The present invention relates to environmental technology field, it is related to organic fertilizer production and organic sewage process field, relates more specifically to Process the dirty method simultaneously producing fertilizer of excrement and its device using stalk.

Background technology

Since reform and opening-up, China's agricultural production there occurs great variety, has liberated agricultural productive force, improves product Amount, but agricultural production also brings agricultural pollution problem.A large amount of straw refuses of planting industry, the substantial amounts of feces of aquaculture are dirty Water, is the big polluter of agricultural production two, and crop straw burning, feces are piled up, sewage crossing current, seriously pollute environment, endanger people Health.

1st, the dirty pollution of aquaculture excrement and treatment status

Aquaculture integrated production capacity significantly increases, and livestock products total output is substantially improved, animal products structure successive optimization, Livestock rearing pattern raises the intensive culture Mode change to high productivity for the pattern scattered from the peasant household of the low productivity, defines area The Production of Livestock and Poultry layout in domain.But in Pollution from livestock and poultry preventing and controlling starting evening, starting point is low, and the fundamentals of management is weak, with scale The fast-developing serious of livestock and poultry cultivation disconnects.Contradiction between animal husbandry and environmental conservation, Pollution from livestock and poultry becomes Important content for widespread pollution from the overuse of fertilizers and pesticides in rural area and water environment pollution.

Livestock and poultry cultivation is specialized to concentrate feeding manner with scale, is conducive to improving breeding technology, pest resistance and management Level, be peasant household's dispersion raising with traditional approach compared with, large-scale breeding is greatly improved production efficiency and feed conversion rate, fall Low production cost, increases economic benefit.But poultry large-scale breeding also results in fecaluria concentrations and flushing water substantial increase, gives Ecological environment brings enormous pressure.Dirty to 23, whole nation province (area), city's scale animal and poultry cultivation industry according to State Environmental Protection Administration Dye status investigation shows, feces of livestock and poultry yield is 2.4 times of industrial solid castoff yield, feces of livestock and poultry COD (COD) considerably beyond China's industrial wastewater and sanitary sewage COD discharge capacity sum.At present, the scale ginseng of livestock and poultry cultivation Difference is uneven, and on a small scale and raise cultivation scattered and still occupy sizable proportion, the difficulty polluting improvement increases.Between time domain Greatly, the animal number in existing soil is extremely uneven for livestock and poultry cultivation amount diversity.The pollution that many areas livestock and poultry cultivation brings is Through or becoming local environment primary pollution source.

Prevent and treat aspect in Pollution from livestock and poultry, taken the lead by Chinese Ministry of Environmental Protection and put into effect many standards and norms texts, such as《Poultry Aquaculture pollutant emission standard (GB18596-2001)》《Livestock and poultry breeding industry waste treatment project technical specification (HJ497- 2009)》Deng, specify that discharge standard and feces of farm treatment technology technique of Pollution from livestock and poultry thing etc., but still scarce Weary practical, operating cost is low, high treating effect, Pollution from livestock and poultry Prevention Technique applied widely or pattern.

And from the point of view of according to various places excrement dirt administration project, treatment for cow manure Facilities Construction many with biogas engineering, three separate one purify, Fermentation bed is main contents, but all there is limitation it is impossible to thoroughly solve excrement dirt problem.As biogas engineering lacks post processing, have If biogas slurry and the biogas residue improving soil beneficial to crop growth utilize improper meeting severe contamination farmland and soil, and most cultivation Field rebuilds light pipe, and facility operation easily sends out fault；Cleaning equipment needs 24h to run, and power consumption is big, and operating cost is high；Fermentation bed takes up an area face Long-pending big, it is not suitable for nervous area in soil etc..Meanwhile, the construction of Pollution treatment installation and operating cost make most plants powerless Undertake, " qualified discharge " pattern is not only difficult to solve the problems, such as Livestock Production Pollution, also feces of livestock and poultry resource can be caused to waste.

2nd, the pollution of straw and utilize present situation；

Numerous scientific workers have carried out fruitful research, straw Edible Fungi, biomass fuel to straw utilization The modes such as material, straw building materials make use of a large amount of straws.But straw-returning is main aspect, straw-returning has compost also field, crosses abdomen Also field, the various ways such as direct returning to farmland.Substantial amounts of organic matter, N P and K and trace element is contained, according to Zhang Fudao et al. in straw Statistics, legume straw is nitrogenous more, and gramineous crop straw contains that potassium is abundanter, during the nutrient that crop material provides accounts for The 13%～19% of state's fertilizer total nutrient, is the important organic fertilizer resource of agricultural production.From existing straw Production rate, 600,000,000 In ton straw, npk nutrient content is equivalent to more than 400 ten thousand tons of carbamide, more than 700 ten thousand tons of calcium superphosphate, more than 700 ten thousand tons of potassium sulfate. But because peasant cultivates custom, geographical conditions, using reasons such as costs, a large amount of straws are not obtained by existing mode.

Invent new excrement dirt Treatment process pattern, inexpensive, simple and practical equipment, by the two of agricultural production big polluter Combined Treatment, produces the high-quality organic fertilizer of planting industry while pollution administration, realizes the recycling of garbage, have Necessity and urgency.
