Description
(1) technical field
The present invention relates to a kind of method of utilizing industrial organic waste to produce fertilizer, be specifically related to a kind of method of utilizing paper mill biochemical sludge and careless slag to prepare fertilizer, belong to the organic fertilizer technique field.
(2) background technology
The generation of China's organic waste is at the forefront in the world, because people's understanding is not high for a long time, adds backward in techniquely, and insufficient investment etc. are all multifactor, and are also more backward to its development and use.At present most of adopt still once utilize mode, technology is simple, and is backward in technique, utilization ratio is low, processing power and utilize scale also very limited.Along with improving constantly of expanding economy and people's level of understanding, the agricultural use of waste will be progressively to the depth development of mass-producing, commercialization, high efficiency.On the one hand, will move towards large-scale, concentrate gradually by small-sized, dispersion the processing and the utilization of organic waste, and realize batch production production, the commercialized degree of waste product is strengthened thereupon; On the other hand, more obvious because the infiltration day by day of modern high technology improves the quality of waste product to the effect of increasing production of agricultural, the mode of utilizing of waste is tending towards various, the exploitation degree of depth and utilization are improved.In addition, changing rejected material to useful resource will combine more nearly with town environment comprehensive improvement and ecological agriculture construction, realize that ecology, economic and social benefit are unified mutually.
Papermaking straw pulp factory produces a large amount of careless slags, and burn processing had both been polluted air mostly, had caused huge waste again.The grass slag contains abundant organism, and thick organic content is 85%～90%, the content of full nitrogen 0.6～1.0%, full phosphorus 1.5%～2.0%, full potassium 1.3%～1.6%, moisture 5%～10%.The biochemical sludge output height that paper mill effluent is handled, discarded mostly at present or extensive using causes secondary pollution easily.The biochemical sludge that paper mill effluent is handled contains higher nutrient, contains organic matter about 50%, full nitrogen about 2.5%, full phosphorus about 0.5%, full potassium about 3.0%.Grass slag and biochemical sludge can be made fertilizer, compound organic and inorganic fertilizer and biological organic fertilizer after treatment.Chinese patent application 03132087.2 discloses a kind of ammonium salt process black liquid that adopts through concentrating the technology of making fertilizer in 2005.1.26, and this technology is the closed cycle flow process, and waste liquid is concentrated and deliver to the insulation storage tank by the tubular type spray; Then, concentrated solution is sprayed on the organism carrier granulates, and drying and pulverizing form solid dry powder; Then, add nitrogen, phosphorus, potassium and in, micronutrient element and amendment.Chinese patent ZL02149247.6 provides a kind of technology that adopts paper mill organic waste xylogen to make fertilizer, with the black liquid is raw material, adopt oxidation, sulfonation, dispersion and high-shear technology, preparation nano level sulfonated lignin mixes the polymers aqueous solution, be used for the slowly/controlled releasing fertilizer coating cementing agent, the organic-inorganic complex fertilizer adhesive for granulating, southern acid dryland soil water-holding agent in dry season, the sand-fixation, water-keeping agent of desertification soil.But, how to utilize two kinds of organic wastes grass slag in paper mill and biochemical sludge to adopt biofermentation technique to make in the fertilizer prior art simultaneously and do not appear in the newspapers.
(3) summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of employing paper mill organic waste grass slag and biochemical sludge to prepare the fertilizer method, and the using method of this fertilizer.
The main raw that the present invention adopts is as follows:

The field effect
On grain and cotton, use compound organic and inorganic fertilizer and make wheat increase yield 29.7%, corn yield increasing 12.6%, cotton volume increase 65.5% than an application of organic fertilizers; Biological organic fertilizer can make wheat increase yield 5.5%, corn yield increasing 6.0%, cotton volume increase 2.7%; Fertilizer can make wheat increase yield 5.9%, corn yield increasing 2.8%, cotton volume increase 6%.The hundreds of demonstrations test shows that the fertilizer effect of increasing production is obvious, and the Powdery Mildew of wheat is had certain prevention effect.Compound organic and inorganic fertilizer can promote the trunk diameter growth and the number of branch of peanut plant, makes output increase by 13.1%, root nodule increase by 8.7%, the sick index of peanut significantly reduce, increase product and throw ratio.Using the single fruit weight that compound organic and inorganic fertilizer makes apple increases by 15.1 grams, and output increases by 8%, and the peach single fruit weight increases by 21.4%, and soluble solid content on average increases by 3.08%, peach increases by 3.04%.Make apple young sprout average increment 6.3cm～10.45cm, blade enlarges markedly, and apple hardness increases 0.68-1.83kg/cm
2, peach hardness reduces, ripen in advance 5-7 days.Compound organic and inorganic fertilizer makes garlic production promoting 20.0% than application of organic fertilizers, and biological organic fertilizer can make garlic production promoting 5.52%, and fertilizer can make garlic production promoting 8.11%.Compound organic and inorganic fertilizer makes plastic tent cucumber volume increase 25.5%, and the content of cucumber Vc improves 16.3% and 37.5%, significantly reduces the content of nitrate in the vegetables, and biological organic fertilizer and fertilizer make volume increase 3.31% and 24.8% on the cucumber respectively.Compound organic and inorganic fertilizer makes radish on average increase production 32.13%, increases income more than 300 yuan, and shift to an earlier date 5-7 days than the check plot breeding time; Cabbage heart on average increases production 21.65%, increases income nearly 200 yuan.Fertilising increases the fungi in the soil, and application of organic fertilizers can increase fungi quantity in the soil, and the quantity increase of using fungi in the biological organic fertilizer soil is especially obvious, maximum increases by 15 times.Using biological organic fertilizer obviously increases actinomycetes number in the soil, and prometaphase application of organic fertilizers material increases the actinomycetes quantity in the soil.
Along with the increase of the application of organic fertilizers material time limit, soil organic matter content improves gradually, and particularly soil quick-acting potassium content increase rate is bigger, and it is more obvious to use microbial fermentation compost raising readily available nutrient of soil content, and wheat hypochnus obviously alleviates simultaneously; Improve soil physical property, the soil weight obviously reduces, and porosity increases.
The present invention has following excellent results:
1, can turn waste into wealth, make the tankage in paper mill become fertilizer, realize cycle development;
2, production method is simple, and production cost is low, is easy to realize;
3, reduce fertilizer amount, improved fertilizer utilization ratio, saved fertilizer cost, can effectively prevent the pollution of fertilizer environment;
4, can significantly improve crop yield, improve quality of agricultural product;
5, can improve the soil, keep soil from packing together;
6, the biology aerobic fermentation technique is applied to the processing of paper mill waste, makes leavened prod effective, and fermentation is fast.
