卧式转筒式沼液原位提质装置
本技术涉及厌氧发酵技术及沼液提质处理
,具体涉及一种卧式转筒式沼液原位提质装置。
技术介绍
沼液,是农林有机废弃物、畜禽粪便、生活有机垃圾等有机废弃物经厌氧发酵后的剩余废液。在厌氧发酵工程中产生大量沼液,若直接倾倒于江河湖泊中,将造成水体污染。沼液农用,是处理沼液的有效措施,不仅可避免污染环境,还可变废为宝。沼液中富含较多营养元素、抗逆、杀菌成分及作物生长促进剂等,是目前研究比较热门的有机绿色肥料。且经发酵后,沼液变得无味,其营养成分又较发酵前更利于农作物的吸收利用,所以沼液在农林废弃物资源化利用中有着广泛的应用前景。但直接从发酵罐出来的沼液,往往含有较多的的沼渣、杂质及浮渣,在农用过程中容易堵塞管路、喷头,导致施用效果不佳,使沼液的应用与推广受到较为严重的制约。沼液提质,是解决沼液农用过程中这些制约的关键技术。目前的沼液提质方法,主要采用沼液离位过滤。常见的沼液离位过滤方法,主要有筛分法和挤压过滤法。但沼液的离位过滤,容易受运输距离及占地面积的限制,造成不便。此外,部分沼液中可能存在重金属超标问题,若不加处理直接农用,势必带来安 ...
