摘要
利用碱法草浆造纸企业产生的固体废弃物:白泥、木质素、生化污泥及废草渣,经堆肥处理后复配、造粒,生产出一种有机-无机复混肥,并进行了农田试验。结果表明:该有机-无机复混肥可有效提高作物产量,改善作物品质,并对土壤具有显著的改良作用。该研究对防止碱法草浆造纸企业固体废弃物污染,缓解国内用肥危机具有重要的意义。
By utilizing the municipal solid waste of alkaline- straw papennaking mills: causticization,lignin, sludge and grass residue,through composting,eompound and granulation,the "Organa-Mineral Compound Fertilizers" was produced,and the field test was done. The results show:this "Organa-Mineral Compound Fertilizers"ean increase crop yield,improve crop quality and improves the soil proterties. This study has an important meanings to proventing the pollution of municipal solid waste in alkaline-straw papermaking mills, and mitigating fertilization's crisis in China.
