Description
技术领域
本发明属于有机固废物一体化处理和资源化利用技术领域,具体涉及一种有机固废物一体化生态资源化利用技术方法。
背景技术
据统计,当前我国每年排放有机固废物在40亿吨以上,这些大量有机固体废弃物在城乡周边囤积和堆放,不仅占据了大量的土地资源,而且也造成了严重的环境污染。如何处理这些有机固体废弃物,如何使这些有机固体废弃物资源化,已经成为城镇现代化建设中的一个重要课题。在我国目前由于技术等多种因素的制约,这些有机固废物绝大部分还没有得到集中工厂化、规模化环保处理和资源化利用。究其原因,主要是处理过程中的堆放占用和污染了大量的土地资源;生产过程产生臭气二次污染环境;生产形不成规模,处理和生产量十分有限,生产装备技术落后,生产效率不高,生产周期长,处理和生产成本高,经济效益不明显或无效益,无法形成产业化经营;处理后加工的产品无法标准化和商品化等问题。
有机固废物是人类生活生产中排放的含碳元素最多的废弃物,不仅含有丰富的有机物,还含有其它一些营养元素,是宝贵的社会财富资源,对其进行节能环保处理和资源化循环利用,即是保护社会生态环境的需要,也是保护人类赖以生存的土地可持续耕作的需要,更是保护人类食物链安全的需要。为了较好的对有机固废物的资源化利用,必须做到:处理与利用过程必须减少对土地的占用,节能环保清洁生产,无二次环境污染产生;可实现集中工厂化、规模化连续处理和生产,实现社会产业化开发与经营;充分运用好微生物发酵技术和生态养殖链技术,大幅度降低生产成本,实现较高的经济效益;使产品标准化和商品化生产与消费,形成良性畅通、可循环的有机固废物消纳渠道。
该发明对多种有机固废物进行生态处理和资源化利用,将其转化为水生动物和畜禽优质饲料,转化为优质的有机生态肥料,既可以消除有机固废物本身污染,又可提高养殖业的生态养殖水平,减轻因大量施用化肥造成的面源污染,恢复土壤生态环境,实现农林牧渔禽产业的可持续发展。
发明内容
本发明目的是针对目前我国利用有机固废物技术中存在的不足之处,提出一种有机固废物一体化生态资源化利用技术方法。该发明不仅可以大量回收利用多种有机固废物,节能减排,而且还可以有效大幅降低其产品生产成本,满足各项性能指标的国家标准要求。
本发明目的是这样实现的:将多种不同有机固废物,通过多种生态技术工艺进行有序处理,形成多种资源化产品,达到一体化生态资源化利用目的,其技术方法为:
(1)按照1:0.3~0.5:0.4~0.7的质量比例,将生活有机垃圾混合物颗粒、酵素渣和甘蔗渣进行搅拌混合粉碎成2~4mm颗粒后,在温度8度~42度,含水量15%~50%的条件下,进行厌氧发酵15天~30天,形成物料A。
酵素是由各种植物包括各种野菜、果实、植物茎根、菌菇、草本药物以及动物机体组织等为原料,经酵母、醋酸菌、乳酸杆菌、芽孢杆菌和霉菌等多种微生物发酵而成的制品,酵素渣是酵素经过提取酵素液后而形成的废弃物,是一种包含水、植物成分、有机酸、糖类、蛋白质、氨基酸、微生物代谢产物、微生物酶及微生物菌体等物质的混合物。甘蔗渣含大量有益菌和活性物质,包括水溶性腐植酸≥14%,粗蛋白≥6.5% 。在上述酵素渣和甘蔗渣中组成高效分解有机物的微生物群体,该微生物群体构成一个复杂而稳定的具有多元功能的生态系统,可抑制有害微生物,尤其是病原菌和腐败细菌的活动,消除生活有机垃圾在分解过程中产生的异闻臭闻。当酵素渣、甘蔗渣和生活有机垃圾混合物颗粒混合后,通过微生物群体联合作用,可以高效率地分解生活有机垃圾,将大分子有机物分解为糖、脂肪酸和氨基酸等短链的低分子有机物,微生物群体以此为养分代谢出水和生物热能,同时以几何级数迅速繁殖。如此微生物群体可以周而复始地不断“吃”掉新投入的生活有机垃圾。通常微生物群体对生活有机垃圾的分解速度为12~48小时,平均约24小时,残渣率为10%~20%。
(2)按照1:0.25~0.6的质量比例,将污水处理厂污泥和物料A进行搅拌混合,形成物料B。
污水处理厂污泥是一种由有机残片、细菌菌体、无机颗粒、胶体等组成的极其复杂的非均质体。污泥的主要特性是含水率高,有机物含量高,容易腐化发臭,并且颗粒较细,比重较小,呈胶状液态。当污泥和物料A搅拌混合后,污泥中的细菌菌体和物料A中的微生物群体相互作用相互依赖,形成新的更多的微生物群体,该微生物群体对污泥中的有机物进行进一步分解,在分解的过程中,同样可以有效消除有机物在分解过程中产生的异闻臭闻。
(3)将物料B放置到宽1.2m~1.6m,高30cm~65cm的水蚯蚓养殖沟中,调控养殖沟温度和HP值,在温度10度~30度,HP值6~8条件下,喂食蚯蚓;按照水蚯蚓养殖沟每平方米面积,可放养密度为:水蚯蚓种蚯蚓1.8万~3万条,孵出至半月龄,可放养10万~12万条,半个月到成体可放养4万~8万条。水蚯蚓最适宜的温度为 20~27℃左 右,此时能较好地生长发育和繁殖,28~30℃时,能维持一定的生长,32℃以上时生长停止, 40℃以上时死亡 ;蚓茧孵化最适 18~27℃,10℃以下时活动迟钝 ;0~5℃蚯蚓进入休眠状态 ; 0℃以下死亡。
蚯蚓引种后,应每隔2~3天投物料B一次。在采收水蚯蚓时,可在晚上停止搅动加气,减少水流量或断水,造成第二天早上或上午坑内缺氧,水蚯蚓就会被迫群聚成团浮于物料B表面或上浮至水面,用捞子捞取即可。
水蚯蚓喜欢生活在这种包含有腐植质丰富的微泥水域的物料B中,以食吸物料B中的有机腐植质、细菌和淤泥为生。一般潜伏在物料B中面下10厘米~25厘米处,低温时深藏于泥中。物料B中要保持微流水,这样可以使水质清新,溶氧量较高,加速代谢产物的散逸,增加蚯蚓的摄食生长。一般水流的流速以2~8厘米/秒为度。速度不能太快,如太快水流会冲走营养物质和蚓茧,影响产出。
物料B在水蚯蚓消化系统中蛋白酶、脂肪酶、纤维酶和淀粉酶的作用下, 迅速分解,转化成为自身或易于其他生物利用的营养物质,经排泄后成为蚯蚓粪。
在养殖沟一端是进料口,通过进料口,可以不断添加物料B,另一端是出口,通过水蚯蚓处理的物料B渣液及水蚯蚓成虫从出口有序排出,养殖沟底部从进料口到出口有一定坡度,在沟底设置有搅拌加气系统。搅拌加气系统由污泥泵、射流泵和管道所组成。
由于水蚯蚓水蚯蚓喜食像物料B这种带有甜味的食料,且物料B具有丰富的腐殖质,因此可以在养殖沟放养高密度的水蚯蚓。为了保证物料B溶氧活性,对物料B要定期搅动加气,在防止凝结的同时,也保证物料B有序循环流动。
(4)从养殖沟出口排出分离出成虫蚯蚓、料液和料渣,成虫
蚯蚓作为特种水生动物甲鱼、河蟹、小龙虾、泥鳅和黄鳝的生态绿色饲料;渣料经过后续工序技术处理成生态有机肥;含有大量蚯蚓粪便和菌群的料液,放置到农林有机垃圾厌氧发酵发生器作为发酵液使用。
在特种水生动物天然食料中,水蚯蚓是理想的喂食食料,不仅营养丰富,有利于特种水生动物的快速生长,大幅提高特种水生动物的产量和质量,也能够提高特种水品的自身抗病能力。
(5)在上述(4)分离出来的渣料中,依次加入按渣料质量百分比所占比重为:电石渣10%~ 15%,粉煤灰13%~ 25%,氰氨化钙10%~ 20%,将上述物料经过搅拌混合熟化,用于酸性土地生态多功能有机肥料使用。
污水处理厂污泥中含有丰富的有机营养成分氮、磷、钾等元素,有机物的浓度一般为60% ~70% ,其含量高于农家肥,是肥田、改良土壤、园林绿化建设的好材料。但是污泥中也含有大量的病原菌、寄生虫卵,以及铜、铝、锌、铬、砷、汞等重金属和多氯联苯、二晤英、放射性元素等难降解的有毒有害物质 ,如果直接利用,对土地对植物都具有一定的危害。
甘蔗渣具有吸附咯金属作用,大量的研究表明,水蚯蚓可通过其砂囊研磨与肠道的生物化学作用,降解污泥中多种重金属效果显著。通过水蚯蚓和甘蔗渣降解吸附作用,可以有效的大幅降低污泥中重金属的含量,提升了氮、磷、钾、氨基酸、腐植酸、粗蛋白等多种营养成分的含量。使上述肥料能够达标(低于NY525-2012农业行业标准要求),可谓是高质量的有机肥。该有机肥可显著提高土壤pH,改良土壤酸性,且施用后土壤碱解氮含量、速效钾含量及有效磷含量均有不同程度的提高,尤其适用于植烟土壤的改良。生态多功能有机肥料含有作物生长所需要的各种生物活性物质,可溶性有机酸、磷、钾等中微量元素,并可产生由于螯合或络合反应而形成含有易被植物吸收的腐殖酸螯合钙及其他微量元素,极大地提高了肥料中矿质养分的利用率及有效性、商品性。该产品可应用于粮食、蔬菜、瓜果等大田作物及经济作物,增产效果明显,易于大面积推广施用。
(6)在农林有机垃圾厌氧发酵发生器中,将上述(4)分离出来的料液和农林有机垃圾粉碎颗粒,按照1:3~5的质量比例进行搅拌混合,酸化处理7~20天后,形成物料C,放置到黑水虻养殖塔。
料液中含有大量蚯蚓粪和菌群,蚯蚓粪因有很大的表面积,使得许多有益微生物得以生存,并具有良好的吸收和保持营养物质的能力。对蚯蚓粪进行检测,蚯蚓粪含氮磷钾分别为1.4%、1%、1%,含腐殖酸46%,含23种氨基酸,有机质含量40%,另外还包含丰富的蚯蚓粪酶,有益菌群2000万个/克~2亿个/克。将上述料液和农林有机垃圾进行酸化处理后,可大量杀灭农林有机垃圾中的致病菌、寄生虫卵,各种秸杆中隐藏的植物害虫以及各种杂草种籽等,利用微生物发酵过程中产生的代谢物质可以有效促进黑水虻的肠胃吸收,提高免疫力。
(7)在黑水虻养殖塔,养殖黑水虻,将成虫黑水虻和通过黑水虻处理后的料渣一起,放置到生态种植养殖园,生态种植养殖园种中种植有牧草和玉米,养殖有牛羊和鸡,成虫黑水虻作为鸡有机生态饲料,料渣中含有大量黑水虻粪和有机物,料渣和牛粪羊粪鸡粪一起作为牧草和玉米有机肥,牧草和玉米为牛羊提供生态饲料。
黑水虻能够有效地减少物料C的臭味,防止家蝇滋生等,是自然界碎屑食物链的重要环节,也是极具开发价值的资源昆虫和环境昆虫。 黑水虻营养丰富,幼虫和蛹是优质的动物蛋白饲料。
生活有机垃圾混合物颗粒为厨房菜渣、果皮、庭园垃圾、纸、纤维和竹木的混合物颗粒。
农林有机垃圾不仅包括农业生产过程中的产物,还包括农林产品加工过程中的副产品,具体包括豆类茎秸、禾本科作物秸秆、玉米芯、各种麦类的糠麸、各种水稻的谷壳和米糠、西沙尔麻淹、香蕉茎和叶,以及锯木屑、中药渣、树枝树叶和人畜禽粪便,粉碎后的颗粒粒径小于1mm。
该发明具有一定的实用性,具体体现在该发明能够制造或者使用,并且能够产生以下积极有益的效果:
(1)本发明将生活有机垃圾、酵素渣、甘蔗渣和污水处理厂污泥通过微生物发酵处理转化为水蚯蚓非常喜欢吃的食物饲料,不仅为水蚯蚓提供了营养十分丰富的食物饲料,大幅提高了有机废弃物的资源化附加值;而且通过将水蚯蚓食用后的残渣用来制作生态有机肥,大幅提高了有机废弃物的资源化利用率。
(2)本发明通过甘蔗渣吸附和水蚯蚓降解处理,使污水处理厂污泥中的重金属含量大幅度降低,有效解决了污水处理厂污泥作为肥料对于植物产生的危害问题。
(3)本发明在冬春季气温低时,利用微生物处理散发的热量,可以提升水蚯蚓和黑水虻养殖环境温度,提高养殖效率,不需要额外能耗。
(4)本发明通过多种工艺组合,使得整体工艺流程资源化利用率达到100%,不但为特种水生动物、畜牧禽产业的发展提供了优质有机营养饲料,延长了产业循环链,提高了投入产出率,而且大幅降低了二次污染的风险,大幅降低了固废处理过程中的能耗。
(5)本发明充分利用现有的经济技术条件,通过微生物链和生态养殖链的延申,建立起行之有效的有机废弃物资源化处理体系,具有完整的生命周期、高效的代谢过程及和谐的生态功能。切实解决生活有机垃圾混合物、污水处理厂污泥和农林有机垃圾高效资源化利用问题。
具体实施方式
将生活有机垃圾混合、农林有机垃圾物和污水处理厂污泥等多种不同有机固废物,通过多种生态技术工艺进行有序处理,形成多种资源化产品,达到一体化生态资源化利用目的,其技术方法为:
(1)按照1:0.3:0.5的质量比例,将生活有机垃圾混合物颗粒、酵素渣和甘蔗渣进行搅拌混合粉碎成2.5mm颗粒后,在温度20度,含水量25%的条件下,进行厌氧发酵25天,形成物料A。酵素渣是由荠菜、山菜、面条菜和马齿苋等野菜, 芹菜根、西红柿和白菜等蔬菜,葛根、丹参和松针等药材多种植物为原料制取的酵素,经过提取酵素液后而形成的废弃物,甘蔗渣是某糖厂榨糖之后剩下的甘蔗渣,约有50%的纤维素,生活有机垃圾混合物颗粒为某住宅小区排放的厨房菜渣、果皮混合物颗粒。
(2)按照1:0.45的质量比例,将污水处理厂污泥和物料A进行搅拌混合,形成物料B。污泥采用某污水处理厂污泥,污泥中有八种重金属,为Hg、Cd、As、Pb、Cr、Cu、Ni、Zn,它们的含量分别是2.5mg/kg,1.96mg/kg,11.3mg/kg,42.2mg/kg,146mg/kg,162mg/kg,51.1mg/kg和505mg/kg。
(3)将物料B放置到宽1.5m,高45cm的水蚯蚓养殖沟中,调控养殖沟温度和HP值,在温度18度~22度,HP值6~8条件下,喂食蚯蚓;按照水蚯蚓养殖沟每平方米面积,可放养密度为:水蚯蚓种蚯蚓2.2万,孵出至半月龄,可放养10万条,半个月到成体可放养6万。水蚯蚓选用苏氏尾鳃蚓,它具有繁殖快、营养价值高,干物质中含粗蛋白62%,必需氨基酸总和达35%,氮回收率达98%,是特种水生动物喜食的优质饲料,特别是鲟、鮠、鲤、鲫、鳅、娃娃鱼及黄鳝等底栖鱼最喜欢吃的食物。随着名优特水生动物养殖业的迅猛发展,苏氏尾鳃蚓越来越受到广大养殖者的青睐。因此,积极开发养殖水蚯蚓很有前途。每亩年产量可达1500~1800公斤,按目前市场最低价每公斤20元计产值达3~3.6万元.。
在养殖沟一端是进料口,通过进料口,可以不断添加物料B,另一端是出口,通过水蚯蚓处理的物料B渣液及水蚯蚓成虫从出口有序排出,养殖沟底部从进料口到出口有1/5坡度,在沟底设置有搅拌加气系统。搅拌加气系统由污泥泵、射流泵和管道所组成。
(4)从养殖沟出口排出分离出成虫蚯蚓、料液和料渣,成虫蚯蚓作为特种水生动物甲鱼、河蟹、泥鳅和黄鳝的生态绿色饲料;渣料经过后续工序技术处理成生态有机肥;含有大量蚯蚓粪便和菌群的料液,放置到农林有机垃圾厌氧发酵发生器作为发酵剂使用。水蚯蚓是理想的喂食食料,营养十分丰富,食用水蚯蚓的特种水生动物的生长周期比食用一般人工饲料缩短25%~36%,产量提高17%~39%,市场价格提高50%~120%。
(5)在上述(4)分离出来的渣料中,依次加入按渣料质量百分比所占比重为:电石渣10%,粉煤灰25%,氰氨化钙18%,将上述物料经过搅拌混合熟化,用于酸性土地肥料使用。通过水蚯蚓降解和甘蔗渣的吸附,通过步骤(5)的进一步生化处理,污水处理厂污泥污泥中原有八种重金属Hg、Cd、As、Pb、Cr、Cu、Ni和Zn的含量大幅下降,经过检测它们的含量分别是0.23mg/kg,0.15mg/kg,2.31mg/kg,3.32mg/kg,8.31mg/kg,23.7mg/kg,5.8mg/kg和32mg/kg。分别下降82%,95.5%,79.6%,92.1%,94.3%,85.4%,88.6%和93.7%。
(6)在农林有机垃圾厌氧发酵发生器中,将上述(4)分离出来的料液和农林有机垃圾粉碎颗粒,按照1:3的质量比例进行搅拌混合,酸化处理15天后,形成物料C,放置到黑水虻养殖塔。农林有机垃圾不仅包括农业生产过程中的产物,还包括农林产品加工过程中的副产品,具体包括豆类茎秸、禾本科作物秸秆、玉米芯、各种麦类的糠麸、各种水稻的谷壳和米糠、西沙尔麻淹、香蕉茎和叶,以及锯木屑、中药渣、树枝树叶和人畜禽粪便,粉碎后的颗粒粒径小于0.6~0.8mm。
(7)在黑水虻养殖塔,养殖黑水虻,将黑水虻和通过黑水虻处理后的料渣一起,放置到生态种植养殖园,生态种植养殖园种中种植有牧草和玉米,养殖有牛羊和鸡,黑水虻作为鸡有机生态饲料,料渣中含有大量黑水虻粪和有机物,料渣和牛粪羊粪鸡粪一起作为牧草和玉米有机肥,牧草和玉米为牛羊提供生态饲料。
黑水虻,是一种利用价值非常高的资源昆虫和环境昆虫。可以将黑水虻加工成昆虫干粉,也可以以活体直接作为饲料喂养鸡,它作为高蛋白质饲料喂养鸡,可以达到相互转化的目的,可以降低养殖成本,形成生物链式养殖。
黑水虻饲养分为并行的两部分,即种虫养殖和幼虫规模养殖。种虫养殖较为精细,要求生产虫体个体大,能够用来产卵繁殖后代,为生产提供不间断的虫源;幼虫规模养殖以生产应用为目的,最大限度地提高幼虫体及预蛹产量。大规模养殖,不仅要考虑到生产数量大,还要达到生产成本低,并且能产生一定的社会效益和生态效益。黑水虻成虫的活动和交配需要较大的空间,理论上讲养殖空间越大越好,牧草和玉米为鸡食用黑水虻活体成虫的活动场所提供十分适宜的生活环境。
生态种植养殖园采用拱棚建设,棚顶高2米左右,拱形。其中一半用窗纱网覆盖,另一半用塑料布覆盖,里面种植牧草和玉米。覆盖窗纱网的目的是便于通风透光,利于棚内牧草和玉米的生长和黑水虻成虫作为鸡活体饲料的暂时饲养;塑料布覆盖,便于黑水虻成虫躲避风雨。放置到生态种植养殖园中的黑水虻成虫不采食食物,只吸食牧草和玉米上的露水,所以不用为成虫投放饲料,但要经常对饲养棚内的牧草和玉米喷水,保持棚内的湿度。
黑水虻养殖塔建造时要在顶部安装碘钨灯泡,便于黑水虻交配。黑水虻种虫养殖密度以每平方米2万~3万只为宜。成虫产卵时,在饲养塔内设置引诱盆采收卵块。黑水虻产卵有一定的选择性,一般选择在比较干燥的木质缝隙间,所以在黑水虻养殖塔要放置引诱盆,盆内放置鸡粪,盆上放置多孔收卵板。用瓦楞纸板或密度板做的收卵盒较为实用。如果收卵板用瓦楞纸箱做成,将纸箱剪成长30厘米、宽6厘米的硬纸条,其中长边为多孔的边。硬纸板大约3~5层叠放起来,密度板一般长33厘米、厚1.8厘米、宽5厘米,层间留有缝隙,缝隙宽度小于2毫米,深度大于7毫米。虫卵每天收集一次,收集时将带有虫卵的硬纸板放在饲料培养盒上面,孵化后的幼虫自动爬行落入饲料中取食。瓦楞纸板也可以用其他带有缝隙的物块代替,如两块木板叠放在一起,由于木板自然弯曲形成缝隙,可供黑水虻产卵于其间。幼虫的饲养将收集到的黑水虻虫卵集中放在孵化盆或盒内,孵化需要2~4天,孵化出的幼虫自动爬行落入饲料中。注意,尽量把一天内产的卵一起孵化饲养,这样到后期幼虫生长整齐,易于管理。3~4天后,幼虫长到0.6厘米左右,这时开始大量取食。根据盆内虫的密度,可以进行分开饲养,幼虫的分离幼虫饲养7~10天后,虫体个头已经形成,当开始有预蛹出现时,部分幼虫停止摄食,也基本停止生长,这时预蛹会大量爬出。虫爬完之后,用铁锹铲出处理完的残渣,提供给牧草和玉米作为有机肥使用。另外一种分离方法是根据幼虫的避光特性,将饲养塔内的虫和料堆积在一起,置于自然光线下,幼虫就会躲避到最下层,然后把上层的废料剔除,剩下的就是幼虫体;如果还有少量的废料,过筛即可,这样也可以减少劳动强度。
在上述说明中,虽然列举了本发明较佳实施例进行了说明,但众所周知,不应由该实施例反而限制了本发明的权利保护范围,亦即,任何熟悉该发明创新点的工程技术科学研究人员,若应用本发明主要之特征,进行若干细节的变动,皆仍应属于本发明的专利保护范围。
