【摘要】 把西安市污水处理厂所产污泥与调理剂(麦糠或玉米秆糠、鸡粪)及膨胀剂(玉米秸秆短节)按一定比例混合,调节水分为50%-65%,C/N 为30,用通气静态垛堆肥化处理,可获得55℃以上的高温5-7d。腐熟的堆肥风干、过筛,混入一定量的尿素和磷肥使全氮达2%,全磷达1%,并补充必要的微量元素制成复合有机肥料。把它施用于林木、花卉、草坪草及用作林木容器育苗基质,均获得良好的生长响应,土壤的物理、化学及生物学性质均有所改善。更多还原

【Abstract】 The Sewage sludge from Xi’an waste water treatment plant was mixed with amendment powder of corn stalk and chicken manure and bulking agent short pieces(3-5cm) of corn stalk at a proper rate,maintaining the moisture of 55-65%,and C/N of 30 the temperature of the mixture could rise to 55-65~C,which could last for one weak at least. The matured compost was air dried and passed through 10mm sieve,and mixed with some urea,calcium superphosphate and some necessary micro-nutrients to make it contain more than 2% N and 1% P.Its application to trees,flowers,turf lands and tree seedling container resulted in good growth responses and improved the physical,chemical and biological properties of soil.更多还原
