Description
技术领域：Technical field:
本发明属于污泥焚烧处理及综合利用技术领域The invention belongs to the technical field of sludge incineration treatment and comprehensive utilization
背景技术：Background technique:
随着城市规模的日益扩大及经济的快速发展，城市污泥的产出量不断增加并给城市的环境和附近河流的生态环境带来严重的危害。城市污泥量的剧增给城市建设带来了障碍。巨大的城市垃圾山中城市污泥占了很大的比例。With the increasing scale of the city and the rapid development of the economy, the output of urban sludge has been increasing and has brought serious harm to the environment of the city and the ecological environment of nearby rivers. The sharp increase in the amount of urban sludge has brought obstacles to urban construction. Urban sludge accounts for a large proportion of the huge urban garbage mountain.
近年来，由于多年的积累和一直没有有效的处理办法，湖泊的污泥污染已对周边的生态环境构成严重威胁。就以滇池为例，目前由于对滇池污染还没有一个行之有效的治理方法，使得滇池池底的污泥淀积了厚厚的一层，仅6.4公里岸边浮泥就达8万多立方米，滇池的草海底泥面积达7.5平方公里左右。污泥及草海中富含氮、磷等营养成分给藻类植物提供了充足的养分，使得藻类疯长，难以控制，造成大量水生动物死亡，使滇池的自净能力急剧下降；另外，如不对污泥中的各种有毒物质及重金属元素进行治理，则其它治理滇池的方法在短期内也难以取得成效。In recent years, due to years of accumulation and no effective treatment methods, the sludge pollution of the lake has posed a serious threat to the surrounding ecological environment. Take Dianchi Lake as an example. At present, because there is no effective treatment method for the pollution of Dianchi Lake, the sludge at the bottom of Dianchi Lake has deposited a thick layer, and the floating mud on the shore of only 6.4 kilometers reaches more than 80,000 cubic meters. meters, and the grassy seabed mud of Dianchi Lake covers an area of about 7.5 square kilometers. Nutrients such as nitrogen and phosphorus in the sludge and grass sea provide sufficient nutrients for algae plants, making the algae grow wildly and difficult to control, resulting in the death of a large number of aquatic animals, and sharply reducing the self-purification ability of Dianchi Lake; If the various toxic substances and heavy metal elements in the lake are treated, other methods of treating Dianchi Lake will be difficult to achieve results in the short term.
公知的污泥处理技术还比较落后，多数采用施肥或堆放处理，很少用其他高效无污染的方法。施肥处理是一项比较传统的技术，但是施肥时容易造成污泥对环境的二次污染，污泥中的重金属随施肥过程一起进入到生态环境中，这对土壤、植物、地下水，甚至大气造成二次污染，同时对食物安全构成严重威胁，严重地危害人类的生存环境和健康。目前各国正致力于寻找新的无害化、减容化和资源化污泥处理方法。把污泥作为低热值燃料进行焚烧处理因为其具有很好的无害化、减容化和资源化效果已在一些发达国家受到重视。但是由于传统焚烧温度较低，一般在800～1000℃，污泥中的其它成分(如Cl、S等元素)，易在燃烧时生成新的二恶英类等有害污染物。而近年来各国十分重视二恶英剧毒物的污染问题，因此现有技术不能适应当前严格的环保要求。The known sludge treatment technology is still relatively backward, and most of them are treated by fertilization or stacking, and other efficient and pollution-free methods are rarely used. Fertilization treatment is a relatively traditional technology, but it is easy to cause secondary pollution of the sludge to the environment during fertilization. The heavy metals in the sludge enter the ecological environment together with the fertilization process, which will cause serious damage to the soil, plants, groundwater, and even the atmosphere. Secondary pollution poses a serious threat to food safety and seriously endangers the living environment and health of human beings. At present, countries are working to find new harmless, volume reduction and resourceful sludge treatment methods. Incineration of sludge as a fuel with low calorific value has been valued in some developed countries because of its good effects of harmlessness, volume reduction and resource utilization. However, due to the low temperature of traditional incineration, generally at 800-1000°C, other components in the sludge (such as Cl, S and other elements) tend to generate new harmful pollutants such as dioxins during combustion. In recent years, countries have attached great importance to the pollution of dioxins and highly toxic substances, so the existing technology cannot adapt to the current strict environmental protection requirements.
