Abstract
The invention relates to a novel method for preparing efficient organic fertilizers from livestock and poultry manures. The method comprises: (1) pre-treatment, wherein livestock and poultry manures react for 20 min at a temperature of 150-180 DEG C under 0.8-1.2 Mpa under the catalyst effect; (2) solid-liquid separation, wherein the treated livestock and poultry manures are subjected to solid-liquid separation; and (3) fertilizer preparation, wherein the separated solid and the separated liquid are respectively prepared into the efficient solid organic fertilizer and the efficient liquid organic fertilizer. According to the present invention, with the method, the environmental pollution problem caused by the livestock and poultry manures is solved, and compared with the traditional bio-fermentation composting, the method of the present invention has characteristics of small occupation area, rapid treatment, complete harmlessness, concurrent production of the efficient solid organic fertilizer and the efficient liquid organic fertilizer, and complete killing of all the pathogenic microorganisms, parasites, and weed seeds.
Description
Technical field
The present invention relates to the production field of organic fertilizer, particularly a kind of method of feces of livestock and poultry efficient organic fertilizer.
Background technology
Feces of livestock and poultry is not only to environment, and serious threat human health.Containing organism such as a large amount of N, P in the fecaluria that livestock and poultry farm produces, meeting polluted source, causes body eutrophication; Stench and the obnoxious flavour such as hydrogen sulfide, indoles, ammonia, amides, amine that Animal fecal pollution anaerobic digestion produces, meeting polluted air, makes Air quality decline; Feces of livestock and poultry also containing a large amount of pathogenic micro-organism, parasite etc., these harmful levels of pathogens, worm's ovum not only contaminate environment, and threaten that people's is healthy by all means.Certainly, the multiple pollutant contained in Animal fecal pollution except contaminate environment, be detrimental to health except, itself also seriously governs the Sustainable development of livestock and poultry breeding industry, has become the bottleneck of the good and fast development of livestock industry.
Containing abundant organic matter in feces of livestock and poultry, treated and processing after can be converted into high-efficiency organic fertilizer, not only can solve livestock and poultry farm problem of environmental pollution, and there are significant economy, society and ecological benefits, to promotion sustainable development of animal husbandry, the benign cycle realizing agriculture production is significant.
Summary of the invention
Technical problem to be solved by this invention is: providing a kind of take feces of livestock and poultry as the method for raw material efficient organic fertilizer.
Technical scheme of the present invention is:
Take feces of livestock and poultry as a method for raw material efficient organic fertilizer, comprise the following steps: (1) pre-treatment: by feces of livestock and poultry under the effect of catalyzer, 150 ~ 180 DEG C, under the condition of 0.8 ~ 1.2Mpa, reaction 20min; (2) solid-liquid separation: the feces of livestock and poultry after process is carried out solid-liquid separation; (3) solid high-efficiency fertilizer processed: isolated solid manure is made solid high-efficiency fertilizer through oven dry, batching, fragmentation, granulation.(4) efficient liquid fertilizer processed: isolated liquid is made efficient liquid fertilizer through concentrated, batching.
In the inventive method, involved feces of livestock and poultry is one or more in all kinds of feces of livestock and poultry such as cow dung, pig manure, chicken manure.
After testing, in SOLID ORGANIC fertilizer, organic content 38-50%(is in butt), total nutrient (nitrogen+Vanadium Pentoxide in FLAKES+potassium oxide) content 4.5-7.0(is in butt), moisture content 15-20%, acidity-basicity ph 6-8.0, the heavy metal content in organic fertilizer, induced worm egg death rate and colititre index meet the requirement of GB8172;
In liquid organic fertilizer, organic content 250-350g/L, total nutrient (nitrogen+Vanadium Pentoxide in FLAKES+potassium oxide) content 45-60g/L, water-insoluble 30-50g/L, chlorion≤25g/L, acidity-basicity ph (1:250 dilution) 5.0-8.0, the heavy metal content in organic fertilizer, induced worm egg death rate and colititre index meet the requirement of GB8172.
The invention solves the problem of environmental pollution that feces of livestock and poultry causes, compared with traditional biological fermented manure, take up an area little, processing speed is fast, thoroughly innoxious, solid and liquid two kinds of efficient organic fertilizers can be produced simultaneously, kill whole pathogenic micro-organism and parasite, weed seed more up hill and dale.
The process diagram of Fig. 1 to be a kind of with feces of livestock and poultry be raw material efficient organic fertilizer.
