  • the methods of clearing manure commonly used in large-scale livestock and poultry farms at home and abroad mainly include blisters, water flushing and dry dung.
  • the common method is blisters and manure.
  • the disadvantage is that the manure stays in the house for a long time. Partial anaerobic fermentation in the manure, producing a large amount of harmful gases such as ammonia, hydrogen sulfide, methane, etc., causing the appetite of livestock and poultry to decline, endangering the health of livestock and poultry, people are forced to solve the problem of poisonous gas pollution with forced ventilation with high energy consumption.
  • forced ventilation makes the livestock house unable to keep warm, and livestock and poultry are susceptible to infectious diseases such as influenza.
  • Water flushing and manure removal method is also a common method of clearing manure.
  • the disadvantages are large water consumption and serious waste of water resources.
  • the dry decontamination method that is, the feces are diverted once they are produced, the dry manure is collected or removed by mechanical or manual means, the urine and the flushing water are discharged from the sewer, and are separately treated.
  • the dry decontamination process is divided into artificial decontamination.
  • the mechanical cleaning of the feces the drawbacks of artificial decontamination is the large amount of labor, poor working environment, low productivity, the advantage of mechanical decontamination is to reduce labor intensity, save labor, improve work efficiency, but currently the domestic production of sewage equipment There are still some defects in the use of reliability, complicated equipment, high failure rate, and difficult maintenance. Whether it is artificial decontamination or mechanical decontamination, urine and flushing water, drinking residual water, increase the flushing water treatment. Quantity and handling difficulty.
  • the above-mentioned methods of decontamination mainly have the following problems: (1) There is no separate collection and delivery system for drinking water in livestock and poultry, and drinking water is directly mixed with feces, urine and flushing water to increase pollution and treatment costs. . According to statistics, the water that is leaked by the pigs in the duckbill-type drinking fountains accounts for about 20-40% of the total amount of flushing water; (2) the flushing water is not separated from the feces and urine, and the flushing water is directly The manure and urine are mixed for subsequent treatment.
  • the treatment method is usually carried out by anaerobic fermentation in a biogas tank, followed by solid-liquid separation, separating the solid part to prepare solid organic fertilizer, and the liquid part is treated according to the sewage and “reaching the standard”.
  • the disadvantage is that a large amount of nutrients are dissolved in the liquid, and the produced solid organic fertilizer has low nutrient content and poor quality; while the liquid is rich in organic matter, nitrogen, phosphorus, potassium, COD and ammonia nitrogen, the common sewage treatment technology is difficult to achieve discharge.
  • Standard even in accordance with the current limit of pollutant discharge standards for livestock and poultry farming (GB18596-2001), COD 400mg/L, ammonia nitrogen 80mg/L and total phosphorus 8mg/L, respectively, are the pollutant discharge standards of urban sewage treatment plants ( The so-called “standard discharge” is actually the root cause of eutrophication of water bodies in GB18918-2002, Level 1 A standard. The so-called “standard discharge” actually pollutes the environment.
  • the mortality rate of pigs in pig farms is generally 3 to 5%. Once the proportion of epidemic cases is even greater, incidents of drinking water source pollution caused by improper treatment often occur, and there are also unscrupulous traders selling resurgence of dead pigs, and profiting directly from them. Threatening the food safety of ordinary people, the problem of isolation and disposal of these dead animals carrying harmful bacteria needs to be solved urgently.
  • the methods for harmless treatment of sick and dead livestock and poultry mainly include high-temperature incineration, landfill and high-temperature composting. The high-temperature incineration method requires extremely high equipment, and the one-time investment cost is high. Most large-scale farms do not have high-temperature incineration.

It is vulnerable to climatic conditions, and a large number of pathogenic microorganisms are carried in sick and dead livestock. It is difficult to completely kill these pathogenic microorganisms by traditional fermentation methods. Large-scale livestock and poultry farms produce a large amount of soil such as placenta during the process of breeding pups. Because of their nutrient-rich nature, they are highly prone to corruption. If not treated in time, it is easy to cause pollution. The current common treatment method is landfill, existence and The same problem is dealt with by dead animals.

Description

规模化养殖场畜禽粪尿及病死畜禽胎盘治理系统及方法 技术领域
本发明属于环保技术领域，具体涉及一种规模化养殖场畜禽粪尿液体及病死畜禽胎盘的污染治理系统及方法，将畜禽粪尿高温好氧发酵，腐化病死畜禽尸体、胎盘等，制备液体有机肥料和固体有机肥料。
背景技术
当前，国内外规模化畜禽养殖场普遍采用的清粪方式主要有水泡粪、水冲粪和干清粪工艺方式，目前常见的是水泡粪清粪方式，缺点是粪便长时间在舍内停留，在粪沟中部分厌氧发酵，产生氨气、硫化氢、甲烷等大量的有害气体，使畜禽食欲下降，危害畜禽的健康，人们被迫以高能耗的强制通风来解决毒气污染问题，但在冬季，强制通风使畜禽舍无法保暖，畜禽易患流感等传染性疾病，同时，大量有毒有害气体也影响饲养人员的工作，危害饲养人员的健康。水冲粪清粪方式也是常见的一种清粪方式，其缺点是耗水量大，水资源浪费严重；后期粪污处理过程中，固液分离后，干物质中养分含量低，肥料价值降低；污水量大，污水中的大部分可溶性有机物仍然很高，增加了处理难度。而干清粪方式，即粪便一经产生便分流，干粪由机械或人工收集、清扫、运走，尿及冲栏水则从下水道流出，并分别进行处理，干清粪工艺分为人工清粪和机械清粪两种，人工清粪的弊端是劳动量大，工作环境差，生产率低，机械清粪的优点是可以减轻劳动强度，节约劳动力，提高工效，但目前国内生产的清粪设备在使用可靠性方面还存在欠缺，设备复杂，故障发生率较高，维修困难，不管是人工清粪方式，还是机械清粪方式，尿液与冲栏水、饮用余水混合，增加冲栏水处理量和处理难度。
总体来说，上述的清粪方式主要存在如下问题：(1)畜禽饮用余水无单独收集、输送系统，饮用余水直接与粪便、尿液和冲栏水混合，增加污染量和处理成本。据统计，每天因猪在用鸭嘴式饮水器饮水漏掉的水约占冲栏水总量的20～40％；(2)冲栏水未与粪便、尿液分离，冲栏水直接与粪便、尿液混合进行后续处理，处理方法通常是用沼气池厌氧发酵后进行固液分离，分离得到的固体部分去制作固体有机肥，液体部分按照污水进行处理并“达标排放”，该方法的弊端是大量养分溶解在液体中，生产的固体有机肥养分低、质量差；而液体中由于富含有机质和氮磷钾，COD和氨氮浓度高，常见的污水治理技术很难使其达到排放标准，即使按照现行的畜禽养殖业污染物排放标准(GB18596—2001)中限定值COD 400mg/L、氨氮80mg/L和总磷8mg/L，其分别是城镇污水处理厂污染物排放标准(GB18918—2002，一级A标准)中限定值的8倍、16倍和16倍，所谓的“达标排放”实际是造成水体富营养化的根源，“达标排放”的污水继续污染着环境。
目前养猪场生猪病死率一般为3～5％，一旦遇到疫情比例还会更大，时常发生因处理不当造成饮用水源污染的事件，更有不良商贩倒卖病死猪，从中牟取暴利，直接威胁老百姓的食品安全，这部分携带有害病菌的病死动物的隔离和处理问题亟待解决。目前，病死畜禽无害化处理的方法主要有高温焚烧、填埋和高温堆肥等，高温焚烧方式对设备要求极高，且一次性投资成本较高，大部分规模养殖场都不具备高温焚烧的条件，且集中焚烧也存在排放污染，收集、转运流程繁琐，监管措施不易到位等一系列问题，另外处理过程造成的二次污染问题也十分严重。目前应用较多是填埋方式，其缺点是运输、填埋成本高，病死畜禽补贴远低于填埋成本，且大部分养殖场员工由于卫生安全知识缺乏，并未做到卫生填埋，造成严重的二次污染。高温堆肥也是病死畜禽无害化处理的一种，其缺点是病死畜禽打碎等预处理过程中，机械损耗、能 耗和设备清洁都将增加处理成本，操作者在病死畜禽打碎，设备清洁，以及更换易损件等过程中易产生交叉感染，增加疫情传播的风险，而且堆肥占地面积大、时间长、易受气候条件的影响，病死畜禽中携带大量致病微生物，传统发酵方式难以将这些致病微生物彻底杀死。规模化畜禽养殖场在繁殖幼崽过程中产生大量的胎盘等污物，因其营养丰富，极易腐败，若不及时处理，极易造成污染，目前常见的处理方式是填埋，存在与病死畜禽处理同样的问题。
中国专利CN203568937公布了一种畜禽粪污处理系统，包括雨污分离系统、干湿分离系统、固液分离系统和生态净化系统，存在的问题是将粪尿与冲栏水、饮用余水混合后再进固液分离，固液分离后的液体中含有大量有机质和养分，COD和氨氮含量显著升高，不仅导致资源浪费，而且增加后续污水处理的处理量和难度，增加处理成本。分离后的固体物料发酵采用自然堆肥方式，该方式占用产地面积大，发酵效率低，有机肥品质差，易受环境因素影响，易产生二次污染，另外，该系统也未涉及畜禽养殖场病死畜禽尸体和胎盘等的处理。
中国专利CN201520168695.4公布了一种封闭式生物降解病死畜禽无害化处理装置，该专利通过添加生物降解化尸菌剂等辅料降解病死畜禽，通过厌氧发酵杀灭寄生虫、虫卵、病菌及病毒，其缺点是厌氧发酵处理时间长，且在固态条件下病死畜禽尸体腐解效率远比液体条件下低，厌氧发酵并不能完全杀死病死畜禽尸体中有害致病菌，存在二次污染的风险。

(五)当热水锅炉承担焚烧垃圾、病死畜禽等易使曝气头堵塞的焚烧物时，启动循环水泵后再启动热水锅炉，热水进入液体保温发酵反应器的换热盘管中循环，对液体保温发酵反应器内粪尿液体进行加热，液体保温发酵反应器排出的臭气经臭气换热冷凝器冷却后送至生物除臭滤塔吸收、转化，达标后经生物除臭滤塔的排气口排放至大气，同时，经臭气换热冷凝器加热的热空气经曝气风机引入液体保温发酵反应器，对液体保温发酵反应器内粪尿液体进行加压曝气，使粪尿和病死畜禽尸体、胎盘等在60℃以上条件下持续发酵3天以上完成整个高温好氧发酵过程，发酵液经稀释后可直接农用；热水锅炉排出的烟气经烟气换热冷凝器冷却后送至生物除臭滤塔吸收、转化，达标后经生物除臭滤塔的排气口排放至大气，同时，经烟气换热冷凝器加热的热空气经热水锅炉的鼓风机鼓入热水锅炉内，为热水锅炉提供新鲜的热空气；含热臭气、烟气和冷空气在臭气换热冷凝器和烟气换热冷凝器中进行热交换的时候，产生的冷凝水被臭气换热冷凝器和烟气换热冷凝器排出经管道排往畜禽舍外的沟渠；
(六)当控制系统检测安装在生物除臭滤塔的干路进气管道安装的温度传感器检测到臭气温度大于40度时，控制系统打开臭气换热冷凝器的进气管道上的电磁阀，关闭旁通支路电磁阀，使进入除臭滤塔的臭气经臭气换热冷凝器冷却；而当控制系统检测安装在生物除臭滤塔的干路进气管道上安装的温度传感器检测到臭气温度小于15度时，控制系统关闭臭气换热冷凝器的进气管道上的电磁阀，打开旁通支路电磁阀，使臭气不进入臭气换热冷凝器降温，使生物除臭滤塔在15度～40度温度区间工作，既保证除臭效果，又使生物除臭滤塔中的微生物不至于休眠或死亡；
(七)当高温好氧发酵完成时，排出的液体有机肥料至贮液池中暂时贮存或直接外运农用；腐解病死畜禽尸体等产生的残渣，如毛发和骨渣送至热水锅炉焚烧，焚烧产生的灰烬与固体粪便一起送至固体发酵系统，发酵制得固体有机肥；

(2)上述技术方案中，在高温好氧发酵反应进行过程中，控制系统根据各液体保温发酵反应器内物料的温度自动控制循环水三通电调阀的开度，使发酵物料的温度始终恒定在设定温度：当第一个发酵对象的液体保温发酵反应器的物料温度低于设定值时，三通电调阀在该回路的开度为100％，向其它液体保温发酵反应器回路的开度为0；当第一个发酵对象的液体保温发酵反应器内物料温度接近设定值时，控制系统控制打开第二个液体保温发酵反应器循环水回路中的电磁阀，三通电调阀做PID调节，使热循环水部分流经第二个液体保温发酵反应器，使第一个液体保温发酵反应器物料温度恒定在设定值的同时，加热第二个液体保 温发酵反应器；由于好氧发酵的过程是放热的过程，随着发酵的进行，液体保温发酵反应器中物料的温度将继续升高，当第一个发酵对象的液体保温发酵反应器物料温度高于设定值时，控制系统降低或者关闭热水锅炉的加热，循环水在循环泵的作用下，使第一个发酵对象和第二个发酵对象的的液体保温发酵反应器循环水产生混合，结果是第一个发酵对象的液体保温发酵反应器内物料温度下降，第二个发酵对象的液体保温发酵反应器内物料温度被提升；电调阀、电磁阀在控制系统的协调控制下，使前一个液体保温发酵反应器的发酵反应热和锅炉加热的热量被送到二个或第N个液体保温发酵反应器，使得各液体保温发酵反应器的温度稳定在设定值且发酵反应产生的热能得到资源性利用；
(3)当液体保温发酵反应器内压力达到设定上限时，自动开启安全阀，排气以降低反应器内压力至设定上限以内。
有益效果
本发明的规模化养殖场畜禽粪尿及病死畜禽胎盘治理系统及方法，对畜禽养殖场养殖过程中产生的粪便、尿液，以及病死畜禽、胎盘，臭气等进行治理，并对粪便、尿液，以及病死畜禽、胎盘等有机废弃物进行资源化治理，符合自然界物质的循环规律，减轻环境负担的同时，也为修复环境提供了资源。
采用源头分离畜禽舍设计，使粪尿在源头上与冲栏水、饮用余水、雨水分离，提高清粪效率，减少用水，保留固体粪便和液体的养分，提高有机肥肥效，同时固液分离得到固体部分可直接发酵制得固体有机肥料，也简化堆肥预处理等步骤，省去大量干辅料的添加，降低处理成本。因未将冲栏水与粪尿混合，且饮用余水未掺入冲栏水中，冲栏水处理量大大降低，冲栏水中含有的COD和氨氮浓度也大大降低，使得冲栏水治理易于达标排放，显著地降低了冲栏水处理的成本。
本发明创新设计，将换热盘管、曝气装置等部件与顶盖固定在一起，优点是减少换热盘管、曝气装置和顶盖等部件对罐体的压力，减少保温罐体的制造成本，更重要的是，当换热盘管和曝气装置等部件发生故障时，只需用起吊装置将顶盖吊出，换热盘管和曝气装置等部件即可以获得维修，大大降低因进入罐体进行设备维修的难度，提高设备维修的便利性。
在本发明中，利用长时间、持续高温杀灭畜禽粪尿和病死畜禽尸体及胎盘等中的致病菌和虫卵，使其达到无害化治理的目标。将猪粪尿和病死猪装入液体保温反应器内，60℃以上条件下持续发酵3天以上，液体中的有害微生物的检测如附图10所示。由图可知，粪大肠菌群值、蛔虫卵死亡率、吸血虫卵死亡率和钩虫卵死亡率都达到标准NY525‐2012《有机肥料》和GB7959‐1987《粪便无害化卫生标准》相关指标要求，液体肥料中的重金属(Cr、Cd、As、Hg和Pb)含量都在525‐2012《有机肥料》限定范围内。由表可知，猪粪尿和病死猪尸体等在60℃以上条件下持续发酵3天以上，猪粪尿和病死猪残体所携带的绝大部分致病微生物均已被杀死，所以，利用长时间、持续高温杀灭畜禽粪尿和病死畜禽中的致病菌和虫卵，使其达到无害化治理，液体肥料中的重金属含量未超过农用限定标准，上述发酵方法及检测指标表明，发酵后的液体达到无害化治理要求，并达到农用标准。
在本发明治理系统中，利用畜禽粪尿增殖嗜热微生物，在高温条件下高速腐解病死畜禽尸体及胎盘等，将病死畜禽尸体、胎盘等中的脂肪、蛋白质和糖类等迅速转化成可溶的小分子有机物，溶入粪尿中，经过稳定后制得液体有机肥料，这不仅使病死畜禽尸体及胎盘经治理后达到无害化、减量化处理目的，而且提 高了液体肥料中有机质和养分含量，增强肥效，也达到资源化利用的目的。腐解剩余的残渣经焚烧得到的灰烬送固体保温发酵反应器内发酵，生产固体有机肥料。
利用经高温好氧发酵的发酵液中携带的大量热量，进行中温或高温厌氧发酵，不仅使得高温好氧发酵的发酵液中携带的热量得到利用，而且使得厌氧发酵的发酵效率大大提高，发酵时间大大缩短，同时中温或高温厌氧发酵的产沼气率比传统常温厌氧发酵高，沼气资源可以得到利用，经过厌氧发酵后，使有机质进一步稳定化，同时消除畜禽粪尿中的臭味，提高液体肥料的品质，改善液体有机肥料的使用性。
附图11为本发明制得的液体有机肥料分析检测报告。
本发明利用臭气换热冷凝器吸收发酵臭气中的热量，降低臭气温度，同时，又通过旁通支路控制进入生物除臭滤塔的臭气的温度范围，避免因进入生物除臭滤塔的臭气过高或过低，导致微生物失效，减低除臭效果，本发明既保证除臭效果，又使生物除臭滤塔中的微生物不至于休眠和死亡。本发明利用臭气换热冷凝器吸收发酵臭气中的热量，用以加热新鲜空气，加热的空气送入热水锅炉内，为锅炉提供新鲜的热空气，降低能耗，提高燃烧效率，同时，本发明利用锅炉燃烧产生的含热烟气对畜禽粪尿液体曝气，一方面锅炉燃烧产生的烟气中含有的大量热量被畜禽粪尿液体吸收，对畜禽粪尿液体加热、保温，提高了发酵效率，降低了能耗，另一方面，烟气中含有大量的如硫化氢、二氧化硫、三氧化硫、一氧化氮和二氧化氮等成分等酸性气体，与畜禽粪尿液体中的水分结合，释放出H+，与畜禽粪尿液体中的OH‐发生中和反应，降低畜禽粪尿液体的pH，减少氨气的释放，降低畜禽粪尿液体减少营养元素的损失，同时也提高了发酵效率。
病死畜禽等固体有机废弃物在热水锅炉焚烧过程中，产生大量颗粒粉尘，这些粉尘经曝气风机引入液体保温发酵反应器内，会引起液体保温发酵反应器的曝气头的频繁堵塞，从而导致曝气头频繁维修，降低粪尿液体发酵效率，故当有病死畜禽等固体有机废弃物焚烧时，热水锅炉排出的烟气经烟气换热冷凝器换热冷凝，而不是引入液体保温发酵反应器内，这样不仅可以避免液体保温发酵反应器的曝气头的频繁堵塞，而且将烟气中的热量进行有效利用。
总之，本发明既节能，又环保，真正实现有机废弃物的“零污染、零排放、资源化利用”的目标。
