针对秦皇岛市面临的城市污泥好氧堆肥土地利用难以实施的现状,以秦皇岛市绿港污泥处理厂城市污泥好氧堆肥为例,对其中的有机质及养分含量进行检测分析,并将检测结果与国家标准和农家肥进行比较。结果表明,秦皇岛市城市污泥好氧堆肥的有机质、氮、磷、钾等养分含量高,pH呈中性,污泥土地利用的潜力较大,是一种值得合理利用的有机肥源。但限于城市污泥好氧堆肥中重金属含量的影响,在农用时可用于油料作物、果树、饲料作物和纤维作物,用于蔬菜和粮食作物应谨慎使用;在用于园林绿化或土地改良时可直接用在中性或碱性土壤上,在酸性土壤上用时需添加部分其他有机物料。但城市污泥好氧堆肥土地利用的前提条件是必须通过灭活处理达到无害化的卫生要求。 In view of the status quo of Qinhuangdao municipal sludge aerobic composting land use is difficult to implement, with Qinhuangdao City Green Port sludge treatment plant sludge aerobic composting as an example, the organic matter and nutrient content of which were detected and detected The results are compared with national standards and farmyard manure. The results showed that the organic matter, nitrogen, phosphorus and potassium of urban sludge aerobic composting in Qinhuangdao City had high nutrient content, neutral pH and great potential for land use of sludge. Therefore, it is a suitable organic fertilizer source. However, it is limited to the effect of heavy metal content in aerobic composting of municipal sludge and can be used in oil crops, fruit trees, forage crops and fiber crops in agricultural use. It should be used with caution when used in vegetables and grain crops. When used in landscaping or land improvement Directly used in neutral or alkaline soil, when used in acidic soil need to add some other organic materials. However, the prerequisite for land use of municipal sludge aerobic composting is that it must meet the hygienic hygiene requirements through inactivation treatment.
