【摘要】 为解决近年来逐年增加的园林废弃物处理问题,通过园林废弃物和污泥进行不同质量比的混合堆肥试验,研究园林绿化废弃物堆肥过程中各项指标的变化情况及堆肥产品应用于工程绿化的可行性。研究发现:园林废弃物与污泥以适当比例混合,能改善堆肥条件,取得较好的堆肥效果;园林废弃物堆肥具有升温快,高温维持时间长,腐熟快,安全性高的优点;现阶段我国园林废弃物利用率较低,其堆肥产品可作为泥炭、有机肥、土壤改良剂的替代品,促进循环经济的发展。更多还原

【Abstract】 In order to solve the problem of garden waste disposal which has been increasing year by year in recentyears, the mixed composting experiment of different quality ratio of garden waste and sludge has been carried out tostudy the changes of various indexes in the process of composting and the feasibility of compost products application inengineering greening. The study found that: Garden waste and sludge mixed with the appropriate proportion can improvethe composting conditions to achieve better composting effect; The garden waste compost has the advantages of fastheating, high temperature maintenance time, maturity, safety; At present, the utilization rate of garden waste in China islow, and its compost product can be used as a substitute for peat, organic fertilizer and soil conditioner to promote thedevelopment of circular economy.更多还原
