摘　　要：污水污泥因其数量巨大,处理难度较高,探究处理新工艺已显得十分迫切。为深入解决污泥处置与矿物肥料紧缺的问题,以污水污泥无害化处理改性有机矿物肥料的研究为引导,简述了有机矿物肥料在改善作物生长与减少营养物质在环境中的损失方面的极大潜力。通过回顾近些年矿物肥料的需求量、价格与时间的关系,分析污水污泥的处置方式与所含有机成分对提高土壤肥力的作用,表明污水污泥无害化改性生物碳基有机矿物质肥料在提高土壤肥力的效果方面具有极大的应用前景。通过总结和对比可预测将污泥中提取的有机矿物肥料经添加矿物元素后进行有效改良,并加入一定量的酸或碱进行灭菌后,可显示出比常规肥料更加高效的作物产量反应值,同时营养物质的缓慢释放效应显示出更加高效和持久的肥效释放能力。Due to the huge quantity of sewage sludge and the difficulty of treatment,it has become urgent to explore new treatment processes.In order to deeply alleviate the problem of sludge disposal and the lack of mineral fertilizers,the research on the modified organic mineral fertilizers for the environmentally sound treatment of sewage sludge was used as a guide to briefly describe the great potential of organic mineral fertilizers on the improved crop growth and reducing nutrient losses in the environment.By reviewing the demand for mineral fertilizers in recent years,price versus time,and analyzing the role of sewage sludge disposal methods and the organic components contained in improving soil fertility.It is shown that the environmentally sound modification of sewage sludge with bio-carbon-based organic mineral fertilizers has a great influence on improving the effectiveness of soil fertility.The summary and comparison can be predicted that the organic mineral fertilizer extracted from sludge effectively modified with the addition of mineral elements and sterilized with a certain amount of acid or alkali can show more efficient crop yield response values than conventional fertilizers,while the slow-release effect of nutrients showed a more efficient and long-lasting fertilizer release capacity.
