          Exploration of reclamation road of sludge disposal in China

             Our country, since the "11th five-year plan" of urban sewage treatment plant sludge disposal is very seriously, has released the urban sewage treatment plant sludge treatment disposal and pollution prevention and control technology policy (try out) ", the urban sewage treatment plant sludge treatment disposal pollution prevention and control of the best feasible technical guidelines (trial) ", the strengthening of urban sewage treatment plant sludge pollution prevention work of notice, the urban sewage treatment plant sludge treatment disposal technology guidelines (try out) "and so on sludge disposal policies that promote the production of the application of sludge disposal technology in our country.In 2003 before the application of the sludge disposal technology is less, the development is relatively slow.In 2003 in Henan Xuchang only has a sludge fertilizer project put into production, sludge disposal technology is applied to production after 2003 the project increases significantly, especially during the period of 5 years from 2006 to 2011, the new production project almost tripled.
             The disposal of sludge treatment technology innovation and technological progress, and the research and development for the national and regional characteristics of the new technology of sludge treatment and disposal, new technology and new equipment, has an important significance to sludge resource in our country's utilization and sustainable development of our country. In recent years, sludge disposal technology and operation of the project was significantly increased, the application of the technology mainly for incineration, composting, bio gas utilization by cement, and other emerging technologies, the new technology increased year by year. The eastern region sludge disposal technology application of the largest proportion, mainly adopts incineration power generation technology, central, northeast, western region resource technology application ratio is relatively small, mainly used for producing fertilizer technology. Nationwide, 3 province sludge treatment technology application projects most are Zhejiang, Jiangsu and Shandong, Sichuan, Inner Mongolia, Qinghai Sea, Ningxia, Guizhou, Tibet and other provinces almost no application of sludge disposal technology.
              According to situation in china, incineration power generation and composting technology have good prospects. Owing to short disposal time and great reduction ability, incineration power generation is suitable for developed areas in eastern china. Due to low investment cost and high added value, composting technology is suitable for middle and western part whose agriculture is developed well. The new sludge sludge disposal technology in microbial protein extraction and sub-critical hydrolysis sludge composting technology has a great development space. The sludge microbial protein extraction technology has the advantages of low cost, small occupied area, short processing time, high value, and sludge hydrolysis in sub-critical fertilizer technology with its rapid ability of organic matter the sludge in low molecule, obtained products with high added value, and has the characteristics of simple operation, no environmental pollution and so on, these will be the future development direction of sludge treatment and disposal of sludge. At the same time, in order to dispose resources in China better development, should establish and perfect the relevant laws and regulations and standards, strengthen the scientific research the technology of sludge resource disposal, overcoming the shortcomings of the existing disposal technology of various resources, and actively develop new sludge disposal technology.
