生化造纸污泥处理问题是目前困扰造纸厂低碳、环境友好发展的瓶颈问题之一。近日,从扬州大学环境科学与工程学院传出喜讯,该院在“利用蚯蚓直接处理生化造纸污泥”取得重大突破。通过蚯蚓腹腔中的消化道可将造纸污泥直接分解转化为高效植物营养物质,整个处理过程中无臭气、废气和其他固体废弃物产生,对周边环境无二次污染。 The problem of biochemical papermaking sludge treatment is one of the bottlenecks that plagued paper mills at low carbon and environmentally friendly development. Recently, from the Yangzhou University School of Environmental Science and Engineering came good news, the hospital in the “direct use of earthworms to deal with biochemical paper sludge” made a major breakthrough. Through the digestive tract in the abdominal cavity of worms, the paper sludge can be directly decomposed and transformed into high-efficient plant nutrients. No odors, exhaust gas and other solid wastes are generated during the whole process, and no secondary pollution to the surrounding environment occurs.
