Information
The establishment of the national "Seventh Five-Year Plan", "Eighth Five-Year Plan" and "Ninth Five-Year Plan" scientific and technological research projects has made my country's new technology of sewage treatment, new technology of sludge treatment, and new technology of reclaimed water reuse to achieve gratifying scientific research results. Some projects have reached the international advanced level. Since the Third Plenary Session of the Eleventh Central Committee, under the guidance of Deng Xiaoping's theory of building socialism with Chinese characteristics, with the continuous deepening of the reform and opening up, my country's sewage treatment business has also developed rapidly. Foreign sewage treatment new technologies, new processes and new equipment have been introduced into my country. At the same time as the application of activated sludge process, AB method, A/O method, AA/O method, CASS method, SBR method, oxidation ditch method, stabilization pond Laws, land treatment methods, etc. have also been applied in the construction of sewage treatment plants. The market of the industry is developed by the sewage treatment process technology that only has the function of removing organic matter in the past. Such as grid machine, submersible pump, sand removal device, mud scraper, aerator, blower, sludge pump, dehydrator, biogas generator, biogas boiler, sludge digestion and stirring system and other large equipment.
Due to the large investment in the construction of large-scale urban sewage treatment plants, my country's construction funds are limited and cannot meet the needs of water pollution control. For this reason, the introduction of foreign funds to build sewage treatment plants has become an important part of the construction funds, which has also accelerated the construction of urban sewage treatment plants in my country. A number of large-scale urban sewage treatment plants have been built and put into operation using foreign loan projects. For example, the largest scale in my country in the 20th century was 600,000 m3/d; Tianjin Dongjiao Sewage Treatment Plant, Chengdu Sanwayao Sewage Treatment Plant, Shenyang North Sewage Treatment Plant, and Zhengzhou Wangxinzhuang Sewage Treatment Plant all had a treatment scale of 400,000 m3/d. d. The construction of these large-scale sewage treatment plants marks the continuous growth of my country's sewage treatment industry, the achievement of sewage treatment technology development in my country, the importance the Chinese government attaches to sewage treatment, and the development of my country's sewage treatment industry to a new level. stage.
