Abstract
The present invention discloses a technique for preparing crude fodder by processing stalks by paper making waste liquid. The present invention is mainly used for crude fodder for herbivorous livestock, which belongs to an A23K class. In the present invention, stalks which are processed by waste liquid after paper making are used as the crude fodder, waste is changed into valuables, and the problems of stalk ammonification and farmland fertilizer application are fundamentally solved. In the present invention, the paper making waste liquid is uniformly sprayed on the stalks, and the stalks are processed at a natural temperature or heated in a closed container after sealing, so the stalks comprises more crude protein, and urea which accounts for 5 wt% of the stalks can be increased. The digestibility of the organic substances of the stalks which are processed by the present invention can be improved by 18%.
Description
The present invention relates to a kind of technology, be mainly used in the roughage of herbvore poultry, belong to the A23K class with the treating straw with waste liquid of papermaking producing fodder.
Handle stalk in prior art uses the ammonia conduct to the stalk inorganic agent of (referring to corn stalk, straw straw, wheat straw) more, the ammonia source is urea, carbonic hydroammonium or liquefied ammonia, strive chemical fertilizer in order to handle the stalk producing fodder with the farmland, if urea is amounted in various ammonia source, then China's now only ammoniated straw consumed urea every year is 160,000 tons, after finish " eight or five ", estimate that the annual consumption urea that needs is up to 1,500,000 tons.Ammoniated straw not only expends a large amount of urea, and because ammonia is weak base, the organic matter digestibility of ammoniated straw only improves 10～12%, still has many nutritional labelings not to be released in the stalk.
Purpose of the present invention will adopt the treating straw with waste liquid of papermaking producing fodder exactly, during with the treating straw with waste liquid of papermaking producing fodder, for making the more crude protein of stalk increase, also can increase a spot of urea.
Papermaking wastewater is meant with the aqueous solution behind the soda boiling stalk, usually promptly emit through extracting alkali and the later waste liquid of lignin, this waste liquid is measured by analysis and is contained DM50%, CP1.92%, Baume degrees 20～23 degree, PH9 and small amount of calcium and phosphorus (Chinese Academy of Agricultural Sciences provides).Because papermaking wastewater contains more nutriment, be stronger alkalescence again in sum, abandon it and will cause severe contamination, utilize it to turn waste into wealth environment.
The object of the present invention is achieved like this:
Papermaking wastewater is spilt cloth equably on stalk, and stalk per ton needs 100～300Kg papermaking wastewater, is not less than 8～12 ℃ condition lower seal 10～14 days at temperature.
Be sprayed at papermaking wastewater on the stalk equably, stalk per ton needs 100～300Kg papermaking wastewater, and stalk buttress in bulk is needed stalk is squirted before the spray waste liquid, heats in airtight container then, treatment temperature is 80～90 ℃, and the continuity processing time is 8～10 hours.
Technology of the present invention can be divided into two kinds of stalk cold treatment and heat treatments: when adopting the stalk cold treatment process, stalk per ton needs 100～300Kg papermaking wastewater, concrete grammar is that waste liquid is sprayed on the stalk by layer equably, or waste liquid evenly mixed with the stalk of chopping, compacting then, use the plastic sheeting good seal again, when temperature is not less than 8～12 ℃, handled 10～14 days.When the direct stacking if do not shred stalk, its way of stacking were stalk buttress in bulk, the papermaking wastewater consumption of stalk per ton was 100～120Kg, and when its way of stacking was piled up neatly for the bundling stalk, spent papermaking wastewater per ton was 280～300Kg.For the bundling stalk closely hutte and then spray waste liquid equably together, also build with plastic sheeting, when temperature is not less than 8～12 ℃, handled 10～14 days.Adopt the stalk Technology for Heating Processing to be meant at stalk and spray waste liquid, heat in airtight container then, treatment temperature is 80～90 ℃.Stalk buttress in bulk is needed stalk is squirted before the spray waste liquid, and stalk per ton sprays 200 premium on currency approximately, and the continuity processing time is 8～10 hours; Can not add water to bundling stalk buttress, the continuity processing time still is 8～10 hours.Contain crude protein in the stalk for making, can be when spray waste liquid or batch mixing, it is better to increase to 5% heavy urea effect of stalk.
The present invention compared with prior art its advantage is: 1. turn waste into wealth, use the treating straw with waste liquid of papermaking producing fodder; 2. because the present invention can be without ammonia or use ammonia less, can save chemical fertilizer greatly like this, thereby alleviate the difficult problem that chemical fertilizer is striven in ammoniated straw and farmland; 3. the organic matter digestibility with treating straw with waste liquid of papermaking can improve 18%.
Below by embodiment the present invention is further specified:
Embodiments of the invention are the waste liquids that adopt the paper mill, Zhuo County, stalk is a suburb of Beijing straw, waste liquid and weigh 5% urea by grass and mix the back layering and be sprinkled upon equably on the straw that prescinds, adjust water content and make it reach 30～40% during processing, compacting then, be sealed in the polybag.
Embodiments of the invention adopt three kinds of waste liquid adding proportions in experimentation: promptly 10%, 20% and 30%; Three treatment temperature conditions: handle when promptly handling 10 hours, 60 ℃ 80 ℃ the time 12 hours, handled 7 days during room temperature (24.78 ± 1.26%), every kind is carried out three repetitions, test specimen after the processing, because of containing moisture content, will measure the content of dry (DM) and neutral detergent fiber (NDF) 60 ℃ of oven dry.Be determined at interior 48 hours dry disappearance rate of sheep rumen with the Nylon Bag method at last and carry out statistical analysis.
The DMdp of straw raw material is 45.13 ± 2.2%, and the DMdp that the different waste liquid ratios of different temperatures are handled the results are shown in following table.
The different proportion papermaking wastewater is handled 10 20 30 X S.E.80 ℃ of DM disappearance rate (%) the waste liquid % of straw under different temperatures, 10h 55.93 ± 0.35 59.77 ± 0.11 61.27 ± 2.05 58.99 ± 2.60 0.8760 ℃, 12h 55.63 ± 3.05 61.20 ± 1.56 63.80 ± 2.36 60.21 ± 4.17 1.39 room temperatures, 7 days 58.23 ± 2.05 62.50 ± 1.85 65.13 ± 1.85 61.96 ± 3.44 1.15
X 56.60±2.21 61.16±1.69 63.40±2.49
24.78±1.26℃
Experimental result shows: 1. add the waste liquid ratio with 20～30% for best, no matter be room temperature or heat, it is 10% group that the dry digestibility of straw all is higher than adding proportion; 2. treatment temperature was best in 7 days with about 25 ℃ processing of room temperature, and its straw dry disappearance rate average out to 61.96% is significantly higher than and heats to 80 ℃ or 60 ℃ two groups.
