摘要
针对城市污泥的特点,阐述了城市污泥和污泥堆肥在草坪方面应用的研究现状、研究方向、污泥利用的优缺点和取得的成果。研究表明在经无害化处理和控制环境风险的前提下,污泥的草坪绿地利用具有回收污泥中养分,促进草坪草生长,改良土壤理化性质等优点,且草坪草对污泥有一定的净化作用。但是污泥由于来源不同,质量差异很大,所以污泥使用量难以确定,病原菌、重金属污染及其他可能的污染问题仍存在争议,认为重点应放在污泥影响草坪的机理研究和污泥质量监督2个大方面继续深入,为污泥在草坪利用上提供理论指导和技术支持。
This article discusses current research,development trends,advantages and achievements of the use of bio-solid on turf-grass,based on characteristics of the bio-solids.On the premise of controlling environmental risk and composting treatment,the use of bio-solids on turf-grass has the advantages of making use of the nutrients in the bio-solid to improve turf-grass growth,soil physical and chemical properties,while,the turf-grass can purify the bio-solids.However,because bio-solids from different sources have different qualities,it is difficult to determine the amount of bio-solid to be used.There is also controversy about pollution from pathogens,heavy metals and other pollutants.The authors hold the view that research should focus on the effects of bio-solids on turf-grass physiological changes and control of bio-solid quality,thus providing theoretical instruction and technical support for future research on the use of bio-solids on turf-grass.
