Analysis on Disposal Technologies of Sludge from Sewage Treatment Plant

For sewage treatment plant sludge disposal technology,the paper introduces status quo of sludge treatment technologies at home and abroad,put forward the traditional sludge disposal technologies,mainly include ocean dumping,sludge digestion,sludge composition,land use and the effective utilization of sludge method,forestland use virescence is given as the growth of the sludge quantity. Sludge disposal is attracting the attentions of the people. This study also introduced the sludge treatment situation at home and abroad,the traditional sludge disposal methods,analyzes the stability and sludge recycling of technologies and application progress. It is concluded that the sludge compost and compost sludge land use conforms to China＇s national conditions of sludge disposal and utilization ways.
