摘要
介绍了4种主要的污泥处置方式的特点,调查分析了福建省污泥产生量与处置现状,提出堆肥化处理工艺,并对堆肥化处理的污泥有机肥进行田间肥效试验,结果表明:施用晒干鲜污泥对大白菜有明显的肥效,但也会加重病害,而经过堆肥化处理的污泥有机肥肥效更显著,病害也较轻,商品菜率较高。结合福建省实际,提出农业利用污泥最终处置方式与若干技术对策。
This article introduced the four main ways of sludge treatment, investigated and analyzed the sludge-producing amount and its treatment in Fujian, the sludge-composting technology was suggested and the organic manure of composted sludge had been used in the fields. The experimental result showed that although the sun dried sludge improved the growth of chinese cabbage, the condition of diseases and insect pests worsened. The organic manure of composted sludge reduced diseases and insect pests and had better effects and increased the commodity rate. At the same time, combining the situation in Fujian Province, the final sludge-trealing way for agricultural utilization and several technological countermeasures were proposed.
