                For a long time, the impact of China's sewage treatment industry "heavy water light mud" tendency, the health of the sludge, the harmless treatment disposal problem has not been taken seriously and addressed, in order to solve the outlet problem of municipal sludge, domestic and foreign scientific and engineering and technical personnel were large research and practice. And with increase of the urban drainage system and improve the sewage treatment rate, sewage sludge production growth, but also makes the sewage problem is more prominent. Therefore, the study of the meaning of advanced sludge harmless technology is becoming more and more significant.
               With the development of our country economy and urbanization, urban sewage treatment scale is continually expanding, the continuous improvement of the degree of sewage treatment, so far in 1993, the have been built and in the construction of a sewage treatment plant has reached 117 seat, sewage treatment capacity reached 513.6 million M 3 per day. Nine - five year period, every day into the sewage treatment plant effluent increased to more than 900 million M 3 per day.
              China attaches great importance to environmental protection workers and utilization technology, Taiyuan Municipal Engineering in 80s to go to Japan for training, and completed the research of aerobic fermentation experiment, and the realization of small scale fertilizer success. Beijing Academy of Environmental Sciences was studied by composting of sewage sludge from Gaobeidian factory, nine - five were studied during the horizontal rotation bin composting test. Mechanical Science Research Institute completed the experimental sludge composting technology in eight - five during the process of equipment and the development of sludge compost. The nine - five period, the State Commission of science and technology have been developed in funding to further research and development of the use of sludge, part of the sewage treatment plant has been used in several ways to explore and experiment the use of sludge.
                Environmental protection workers of our country attaches great importance to and use of technology, Taiyuan Municipal Engineering in 80 in the 1990s, China has been part of the Institute, and sewage treatment plant of sludge harmless technical process was studied, and some small experimental; Academy of machinery science during the five - eight completed the research topics assigned by the State Science and Technology Commission "aerobic sludge composting equipment, and in Tangshan to build a demonstration project; in nine - five year period to complete the assigned by the State Science and Technology Commission research project on the sludge of fertilizer complete equipment", and has in Tangshan, Qinhuangdao construction demonstration project.
                By 2000, some sewage treatment plants have been built in our country, and the process is simple:
          1. Dalian Development Zone sewage treatment plant launched a sludge drying project
          2. Sewage treatment plant in Zibo City, Shandong province launched the sludge drying fertilizer project;
          3. Sewage treatment plant in Baoding City, Hebei province launched a sludge drying fertilizer project.
             Although there are many sewage treatment plant sludge drying of fertilizer project, but lower the level of process technology, low efficiency, high energy consumption. With strengthening of people's environmental protection awareness, especially after "SARS" in 2002, China's sewage treatment plant sludge disposal problem has been put on the agenda, many waste water treatment plant are exploring effective sludge treatment method, which has a representative is:
            1. The sludge in Daxing farm of Beijing City Drainage Group annual processing 100 thousand tons of sludge;
            2. The Shanxi province Taiyuan City Drainage Group fertile soil fertilizer company;
            3. The western suburbs of Hebei province Tangshan City two sludge harmless project
             Though, our country of municipal sludge processing greater emphasis on strength, improve the sludge treatment policy is in recently, however, the sludge treatment but after a relatively long process, to understand China's municipal sludge treatment process, realize sludge treatment reduced the important pollution incident occurred in our country, for sludge in China pay more attention to the background, to carry out the sludge treatment and sludge disposal has very important significance. Zhengzhou Taida energy saving drying equipment Co., Ltd. is a professional, the company has mature sludge treatment technology and rich sludge treatment engineering experience, welcome to sludge process owners to Division I negotiate cooperation.
