   In recent years, with China's urbanization process continues to accelerate, sewage treatment scale and level of treatment also in constantly improving. Concomitantly, our country appeared the problems of processing, the elimination of pollution of sludge has become in our country at present, it is imperative to work. China's relatively broad geographical, economic level, natural features are different, the sludge and the sludge treatment disposal should also depend on the city itself.
   China has a vast area, the capacity of sewage treatment plant is different, so the amount of sludge produced. According to the 2011 statistics show: the eastern 10 provinces (city) (including Beijing, Tianjin, Hebei, Shanghai, Jiangsu, Zhejiang, Fujian, Shandong, Guangdong and Hainan) the sludge quantity accounts for the total amount of sludge 61.1%; 6 central provinces (including Shanxi, Anhui, Jiangxi, Henan, Hubei and Hunan) the sludge production accounted for 16.2% of the total amount of sludge; northeast 3 provinces (including Liaoning, Jilin and Heilongjiang) the sludge production accounted for 9.5% of the total amount of sludge; 12 western provinces (City) (including Inner Mongolia, Guangxi, Chongqing, Sichuan, Guizhou, Yunnan, Tibet, Shaanxi, Gansu, Qinghai, Ningxia and Xinjiang) the sludge production accounted for 13.2% of the total amount of sludge, and due to the regional economic environment, with no sludge disposal, the suitable is different, so in There are also great differences in the application of resource management technology.
    The eastern region because of the developed economy, high degree of industrialization, the sewage treatment capacity, sludge production, sludge disposal application proportion, the overall proportion of 68%, mainly adopts incineration power generation technology, the application of 55%. in the middle of the proportion of the total area, north eastern area and western area than the Eastern region due to the economic owe developed, the sewage treatment capacity is weak, small amount of sludge, sludge disposal application proportion is small, respectively, the overall proportion of 15%, 9% and 8%. due to the more developed agriculture, agricultural land is relatively rich, so more, which covers an area of composting technology applied the most, middle, the application of this technology in Northeast China and the western region respectively of the total application proportion of 33%, 57% and 57%.
    From the view of nationwide, 2003-2011, sludge treatment technology application project up to the first three provinces: zhejiang, jiangsu and shandong, and the three provinces in the eastern region.Of zhejiang province is the main application of garbage incineration power generation, brick and system technology, covering soil is the main application of incineration power generation in jiangsu province and making technology, mainly used in shandong, fat burning and the biogas utilization technology., Inner Mongolia, qinghai, ningxia, guizhou and sichuan, Tibet, these provinces in 2003-2011, no sludge disposal technology application project.At present, with the concept of sustainable development and gave birth to his civilization construction is put forward, the recycling of the sludge disposal technology research has made some progress, these technologies have also begun to attempt to engineering.The construction of harmonious environment to the recycling of the sludge disposal.
