In recent years, with the acceleration of urbanization in our country, the urban sewage treatment has been rapidly developed and the urban sewage treatment rate has been increasing year by year. However, a large amount of sludge generated during the urban sewage treatment has not been effectively treated yet. At present, there is an unbalanced regional development in the sludge treatment equipment industry in our country. The developed regions pay more and more attention to sludge disposal. However, in some economically underdeveloped areas, sludge disposal has not yet started. The future business in order to obtain rapid development, but also depends on the policy of further guidance. The State Council's "Opinions on Strengthening Urban Infrastructure Construction" put forward that by 2015, sewage will be "fully collected and fully disposed" in 36 urban areas of major cities, centralized sewage treatment will be implemented in all cities in the country, and the urban sewage treatment rate will reach 85% The construction of sewage pipe network 73,000 km. In accordance with the requirements of "innocuousness and resource utilization", the construction of sludge treatment and disposal facilities will be strengthened, and the harmless disposal rate of urban sludge will reach about 70%. The large amount of sludge generated in the urban sewage treatment process contains toxic and harmful substances such as refractory organic matter, heavy metals and pathogens which, if left untreated, will have adverse effects on the surrounding environment and may even cause infectious diseases. As the state pays more and more attention to the sludge treatment and disposal, the sludge disposal equipment industry ushers in the development opportunity. In order to avoid secondary pollution of sludge from the treatment plant, governments of all countries attach great importance to the disposal of sludge. The technical route of sludge treatment and disposal in the United States has been dominated by agriculture and a great deal of safety assessment has been done for sludge agriculture. The EU and most European countries have increasingly supported the land use of sludge and the proportion of land use has increased The higher is in Japan. Due to limited land resources in Japan, the main technical route of sludge disposal and treatment is the utilization of building materials after incineration, supplemented by agriculture and landfill. At present, the treatment and disposal of sludge in our country is still dominated by landfills, covering a large area and easily causing secondary pollution to the environment. Sludge treatment of sewage treatment plant, disposal system equipment, research and development abroad earlier, in the 1960s has reached the level of advanced complete sets, and sludge treatment and disposal technology and equipment in China there is a big gap with foreign countries. We should learn from foreign experience, the introduction of mature foreign technology processing system, and according to the characteristics of sludge in our country. For sludge disposal equipment manufacturers, horizontal expansion of products should focus on diversified development strategies in the future. In addition to industrial sludge treatment facilities, it is also possible to increase R & D investment in urban sludge treatment facilities. From a product perspective, the company can expand its equipment structure to develop the entire sludge treatment system, including upstream mixing, downstream transmission, and drying of the sun room, extending the product's longitudinal structure. It is understood that at present, the United States, France, Switzerland, Sweden and the Netherlands and other countries of the urban sludge utilization rate of about 50%, Luxembourg, up to 80%. However, only about 10% of sludge treatment in our country is returned to land through composting treatment, another 20% is used for sanitary landfilling, and a small amount of incineration and building materials are used for disposal. The remaining 70% are only casual Transport, simple landfill or piling up, have a serious impact on the environment. Sludge treatment and disposal have been listed as "key" during the "Twelfth Five-Year Plan", which brings tremendous market opportunities and opportunities for the sludge treatment industry. ã€Print】 ã€Close】
