摘　　要：采集了河南省18个地市具有代表性的污水处理厂的污泥样品,分析了其理化性质和养分含量。结果表明,河南省城市污泥的平均含水率、p H值和电导率分别为81.16%、7.37、1.32 m S/cm,与当地的鸡粪和猪粪相比,p H值相近、电导率偏低;河南省城市污泥的养分含量丰富,有机质及总氮、总磷、总钾含量分别为551、31.12、22.36、9.44 g/kg,氮、磷、钾养分总含量达到了62.92 g/kg,比猪粪的高44.38%,比鸡粪的高4.67%。除驻马店污泥因为p H值和电导率偏高不满足相关标准外,其他污泥经过无害化处理后土地利用潜力十分可观。Sewage sludge samples from representative sewage treatment plants in 18 cities of Henan Province were collected, and their physical and chemical properties and nutrient content were ana- lyzed. The results showed that the average moisture content, pH value and conductivity of the sewage sludge were 81.16%, 7.37 and 1.32 mS/cm, respectively. Compared with the local chicken and pig manure in Henan Province, the pH value was similar, and the conductivity was relatively low. The sew- age sludge in Henan Province was rich in nutrient content, and the organic matter, total nitrogen, total phosphorus and total potassium contents were 551 g/kg, 31.12 g/kg, 22.36 g/kg and 9.44 g/kg, re- spectively. The total amount of nitrogen, phosphorus and potassium in the sewage sludge was 62.92 g/ kg, 44.38% higher than that of the pig manure, and 4.67% higher than that of the chicken manure. Except that the sewage sludge from Zhumadian could not meet the relevant standards due to its high pH value and conductivity, the land application potential of sewage sludge from other cities was very consid- erable.
