Comprehensive utilization technology as a resource by incineration treatment on sludge from printing and dyeing wastewater

The wastewater and sludge discharged in a large volume from printing and dyeing works bring severe pollution.At present,the major problems of sludge disposal include the lower sludge disposal rate,imperfect technology,lagging technical equipment,the lower level of management and design,and less investment etc.So the pollution would pose a great threat to the environment if no action were effectively taken.The article discusses the source and harm of wastewater sludge,sludge disposal and its dry-hot work and so on.Meanwhile it introduces and emphasizes the sludge incineration treatment technology.
