摘要:對長江經(jīng)濟帶典型城市污水污泥、通溝污泥、河湖底泥采集測試，分析其有機質(zhì)、含砂量、熱值、重金屬、微量污染物等指標。結(jié)果表明：污水污泥有機質(zhì)含量為30%~50%，熱值一般在5 500~11 000 kJ/kgDS，污泥熱值與有機質(zhì)含量有較大關(guān)系，即有機質(zhì)含量越多，污泥熱值越高；污泥含砂量較高，養(yǎng)分含量為6%~8%，重金屬含量較低，95%以上脫水污泥樣品中的重金屬含量遠低于《農(nóng)用污泥污染物控制標準》（GB 4284—2018）A級標準的限值，處于相對清潔水平；多環(huán)芳烴濃度較低，風險較小。通溝污泥成分復(fù)雜、有機質(zhì)含量范圍廣，約5%~90%，通常熱值和養(yǎng)分較低。河湖底泥有機質(zhì)含量通常小于10%，熱值不到1 000 kJ/kgDS，養(yǎng)分低。通溝污泥和河湖底泥重金屬含量滿足《土壤環(huán)境質(zhì)量 建設(shè)用地土壤污染風險管控標準（試行）》（GB 36600—2018）第一類篩選值，可用于生活居住地的建設(shè)用地。
Abstract:The organic matter, sand content, calorific value, heavy metals, trace pollutants and other indicators of typical municipal sewage sludge, ditch sludge and sediment from rivers and lakes in the Yangtze River economic belt were collected and analyzed. The results showed that the organic matter content of sewage sludge was 30%-50%, and its calorific value was generally in the range of 5 500-11 000 kJ/kgDS; the calorific value of sewage sludge had a great relationship with the organic matter content, that was, the more the organic matter content, the higher the calorific value of sludge; the sand content was high, the nutrient content of sludge was 6%-8%; the heavy metal content was low, and the heavy metals in more than 95% of dehydrated sludge were far lower than the limit of class A criteria specified in the Control Standards of Pollutants in Sludge for Agricultural Use (GB 4284-2018), and at relatively clean level, with low concentration of PAHs and low risk. The composition of ditch sludge was complex, and the organic matter content ranged from 5% to 90%, which was usually low in calorific value and nutrients. The content of organic matter in sediment of river and lake was less than 10%, and the calorific value was low, less than 1 000 kJ/kgDS, with low fertility. The heavy metal content of ditch sludge and sediment of river and lake met the first category screening value of Soil Environmental Quality Risk Control Standard for Soil Contamination of Development Land (GB 36600-2018), which could be used for construction land of residential areas.
