印染污泥在草坪草栽培中的应用研究

An Application of Textile Dyeing Sludge in Phyto-Management of Turf Grass

为了解印染生化污泥对植物的生长影响，探讨了印染生化污泥在草坪草栽培中的应用。通过盆栽试验，研究8种草坪草在印染污泥和土壤的不同配比下的生长响应、印染污泥理化性质的变化以及重金属对环境的影响。试验结果表明：通过草坪草的栽培能明显改善印染生化污泥的理化性质，同时印染污泥对草坪草的生长有明显的促进作用，使植物叶色加深、生长速度加快。试验结果为印染废水生物处理方法产生的剩余污泥处置提供了1种新途径。

By pot-culture experiment of eight turf grass species in the media blended with various proportioning of textile dyeing sludge and soil, influences of the sludge on soil properties and turf grass growth were studied. It indicated that physico-chemical properties of the sludge could be evidently improved meanwhile the plant growth promoted, its leaf colour heightened, and contents of some heavy metals in the sludge such as Cu, Cd, As, Pb and Cr declined with time. It has shown a new way that could be used to dispose of residual sludge generated in the biological process of printing and dyeing wastewater treatment.
