Description
技术领域
本发明属于有机肥料技术领域,具体涉及一种利用畜禽养殖废弃物制备生物有机肥的方法。
背景技术
畜禽养殖废弃物是在畜禽养殖过程中产生废弃物,主要包括畜禽类排放的粪便、冲洗废水等,畜禽养殖废弃物已经成为农村的重要污染源,其具有排放量大,有机物浓度高,含有大量的氨、氮、磷和病原微生物,重金属和抗生素含量超标等特点,对周边生态环境和居民的生活环境带来重大污染,更为严重的是畜禽养殖废弃物未经有效处理流入江河湖泊,严重威胁下游流域的水质安全。研究发现畜禽粪便和废水中有机质、氮、磷、钾等多种营养元素含量高。粪便经堆肥处理后,腐殖酸、C/N、阳离子交换量等理化性质发生显著变化,更便于植物和微生物吸收利用,与化肥相比,施用有机粪肥具有明显的优势。但是畜禽养殖废弃物在肥料化利用过程中仍存在一些问题,例如简单堆肥发酵直接还田,这种简单堆肥发酵的方式一方面在发酵过程中畜禽养殖废弃物经腐败分解形成硫醇、硫化氢、氨气、吲哚、有机酸、粪臭素等有毒有害物质散发出恶臭,另一方面由于加工工艺粗放无法保证发酵温度、发酵不均匀不能完全杀灭有害菌、降解有毒物质,没有质量保证,使畜禽有机肥还田利用受到阻碍;而要深化处理,则需要投入的成本太高。
发明内容
针对上述不足,本发明公开了一种利用畜禽养殖废弃物制备生物有机肥的方法,解决畜禽养殖废弃物发酵生产有机肥过程中存在的易分解形成有毒有害物质和有机肥品质差的问题。
本发明是采用如下技术方案实现的:
一种利用畜禽养殖废弃物制备生物有机肥的方法,其包括以下步骤:
(1)取枯草芽孢杆菌、蜡样芽孢杆菌、假单胞菌和固氮菌溶于水中,接着超声分散10~15min,然后再加入琼脂培养基中且在35℃下培养24~48h得到混合菌液,向混合菌液中加入凹凸棒粉继续搅拌1~2h,然后冷冻干燥得到复合菌剂A;所述的枯草芽孢杆菌、蜡样芽孢杆菌、假单胞菌和固氮菌的质量比为(5~10):(5~10):(3~5):(1~3);所述的凹凸棒粉的质量和混合菌液的体积比为1g:(20~30)mL;
(2)将畜禽粪便和畜禽养殖废水搅拌混合均匀,然后加入步骤(1)中得到的复合菌剂A混合均匀,接着在50~60℃下发酵24~48h得到浆料A,向浆料A中加入絮凝剂搅拌反应1~2h,再静置15~30min,过滤得到浆料B;所述的畜禽粪便、畜禽养殖废水和复合菌剂A的质量比为1:(5~10):(0.05~0.1);所述的絮凝剂的质量和所述浆料A的体积比为(8~10)g:100mL;
(3)取红薯茎叶、甘蔗渣、豆粕和香茅草混合粉碎过80~100目筛得到渣粉,将渣粉和水按照质量比为1:1的比例混合均匀,然后加入复合菌剂B在30~40℃且搅拌速度为20~50r/min的条件下发酵24~48h得到浆料C;所述复合菌剂B包括以下重量份数的组分:纤维素酶10~15份、半纤维素酶10~15份、酵母菌3~5份;所述复合菌剂B和渣粉的质量比为(1~2):10;
(4)将步骤(2)中得到的浆料B和步骤(3)中得到的浆料C混合继续在30~40℃下搅拌发酵10~15天得到液体有机肥;所述浆料B和浆料C的质量比为1:(3~5)。
进一步的,步骤(1)中所述的凹凸棒粉为改性的凹凸棒粉,其制备方法是取粒径为80~100目的凹凸棒粉和聚乙烯醇、柠檬酸钠混合后加入至水中,然后在80~100℃下搅拌反应2~3h,再过滤、干燥得到改性凹凸棒粉;所述的凹凸棒粉、聚乙烯醇和柠檬酸钠的质量比为10:(1~3):(0.2~0.5)。采用聚乙烯醇和柠檬酸钠对凹凸棒粉进行改性,提高凹凸棒粉的吸附性能,使得凹凸棒粉能够更好的吸附和固定微生物,提高微生物菌剂的稳定性和活力。
进一步的,步骤(2)中所述搅拌的速度为200~300r/min。通过控制搅拌速度,促进絮凝剂在浆料中的分散,提高絮凝剂的絮凝作用。
进一步的,步骤(2)中所述絮凝剂的制备方法是取粒径为100~120目的蛭石在100℃下加热膨胀,然后加入至聚丙烯酰胺、乙烯基磺酸钠和水混合的溶液中搅拌均匀,再加入过硫酸铵在60~80℃下反应1~2h,自然冷却至室温后过滤、干燥得到絮凝剂;所述蛭石、聚丙烯酰胺、乙烯基磺酸钠和过硫酸铵的质量比为100:(5~10):(1~3):(0.2~0.5)。采用聚丙烯酰胺和乙烯基磺酸钠对膨胀的蛭石进行表面改性,不仅提高了蛭石的吸附性能,而且改善了蛭石的疏水性,进而提高絮凝剂的絮凝性能,从而更好的絮凝去除浆料中的重金属。
进一步的,步骤(3)中所述的红薯茎叶、甘蔗渣、豆粕和香茅草的质量比为(1~5):(5~10):(10~20):(1~5)。通过加入富含微量元素的香茅草来完善有机肥料的营养组成,并且通过控制红薯茎叶、甘蔗渣、豆粕和香茅草的配比来调节各种营养搭配,从而满足植物生长的营养需求。
进一步的,步骤(3)中所述的超声分散采用的是功率为100~200W。
进一步的,步骤(4)中所述搅拌的速度为20~50r/min。通过控制搅拌速度,在发酵过程中气体发散,调节氧气供给,排除二氧化碳,有利于菌种的生长繁殖,并且使得浆料温度均匀,提高发酵效率。
本技术方案与现有技术相比较具有以下有益效果:
1、本发明采用不同种类和不同特性的枯草芽孢杆菌、蜡样芽孢杆菌、假单胞菌和固氮菌进行复配加入至畜禽粪便和畜禽养殖废水中进行处理,通过各个菌种之间的协同作用起到降解抗生素,吸附钝化重金属和解磷固氮的效果,同时通过科学配制不同菌种的用量比例,促进各个菌种之间的协同效应,减少拮抗作用以及发酵产生的代谢产物对菌株的抑制作用。本发明还采用改性的凹凸棒粉配制复合菌剂,利用改性凹凸棒粉的吸附微生物菌株,提高微生物菌剂的稳定性和活力,获得更好的作用效果。
2、本发明采用聚丙烯酰胺和乙烯基磺酸钠改性蛭石制备得到絮凝剂,提高其在浆料中的分散性和吸附重金属的能力,有效絮凝去除钝化的重金属,同时能够吸附发酵过程中分解形成硫醇、硫化氢、氨气、吲哚、有机酸、粪臭素等有毒有害物质,减少臭气和毒害。
3、本发明先将红薯茎叶、甘蔗渣、豆粕和香茅草混合,并且使用纤维素酶、半纤维素酶和酵母菌复配的菌剂进行预处理,分解红薯茎叶、甘蔗渣、豆粕和香茅草中含有的大量难于降解的木质素,不仅提高后续发酵的效率,而且可以为菌种繁殖提供营养。
4、本发明红薯茎叶、甘蔗渣、豆粕、香茅草和经过处理的畜禽废弃物浆料混合进行发酵制备得到液体肥,其具有营养成分充足、搭配合理,肥料利用率高,肥力持久等特点,可以为各种作物生长提供营养,提高作物产量。
