摘要
研究的目的是城市污水、污泥资源化利用阀题,通过对南阳市污水、污泥经过堆积发酵除臭、造粒、烘干杀菌、包裹处理，将污水、污泥制成有机肥．研究发现，城市污泥含有较高的有机物及氮、磷、钾等养分．结果表明，有机肥颗粒中有机碳、全氮、全磷及全钾的平均含量分别为10．35％、3．24％、1．72％及1．17％，其全氮、全磷的含量比其他有机肥的含量高，全钾含量和其他有机肥的含量基本相同．制有机肥是利用城市污水、污泥一种变废为宝的资源化利用方式．
The purpose of this paper is to study the resources city sewage sludge utilization. Through the Nanyang city sewage sludge compost fermentation and deodorization, after granulation, drying and sterilization, package processing, the sewage sludge to produce organic fertilizer. It is found that city sludge contain high organic matter, nitrogen, phosphorus, potassium and other nutrients. The results show that the average content of organic fertilizer, organic carbon, total nitrogen, particulate phosphorus and total potassium were 10.35%, 3.24%, 1.72% and 1.17% respectively. The content of total potassium and other organic fertilizer content are basically the same With other organic fertilizer, while the content, of total nitrogen and total phosphorus are higher than other organic fertilizer. Organic fertilizer is the utilization of a city sewage sludge waste utilization. Use of urban sewage and sludge system producing organic fertilizer is a way of recycling use of waste.
