After more than 20 years of development, China's water treatment equipment is gradually becoming mature. To catch up with the technological level of developed countries, we must continuously increase our own research and development capabilities under the guidance of water supply and drainage technology theory, and skillfully select advanced foreign water industry equipment in the late 1990s and digest and absorb them. The gap between China's water treatment equipment and foreign countries is greater than the gap between water technology and foreign countries, and the gap between the theoretical research and manufacturing of water special equipment and foreign countries is greater than the gap between general equipment and foreign countries. To improve the level of water treatment in China, the key is to improve the level of water treatment equipment, especially to improve the level of water treatment special machinery and equipment, which is the top priority of China's water industry.
Many years of engineering practice have clearly shown that the normal operation of water treatment equipment is the basis and guarantee for completing the process route. The quality and life of water treatment equipment are the key to the success of the project construction and operation. The price of water treatment equipment is important to the total cost of the project. Influence, the innovation of water treatment equipment plays an active, complementary and perfecting role in the development of new technologies. Therefore, the key to the success of water treatment projects lies in equipment, which has become the consensus in the industry.
At present, water treatment equipment is generally divided into two categories: general equipment and special equipment. General equipment mainly includes pumps, fans, valves, etc. Special equipment is the focus of water treatment research. It mainly includes pollution control equipment, sand scraping and mud scraping equipment, aeration and stirring equipment, medicine and disinfection equipment, concentration and dehydration equipment, etc. In recent years, membrane treatment equipment, Energy saving and biogas utilization equipment, water reuse equipment, sludge disposal and solid waste treatment equipment, etc.
The overall development direction of water treatment equipment is the development of new water treatment equipment, and the new water treatment equipment must fully reflect humanity, environment and modernization. In terms of sewage treatment and its recycling, the focus is on the following aspects: first, sludge post-treatment (sludge thermal drying equipment, sludge incineration equipment, etc.); second, deodorization (chemical deodorization equipment, Biological deodorization equipment), the third is disinfection (ultraviolet disinfection equipment, ozone disinfection equipment and chlorine dioxide disinfection equipment), the fourth is recycling (dosing equipment and membrane processing equipment-microfiltration, ultrafiltration and reverse osmosis equipment), the fifth is New energy-saving processes and supporting facilities. Six is the improvement of traditional processing equipment.
Process is the dominant, equipment is the foundation, technology is the premise of determining the equipment, and equipment is the guarantee to realize the process. The general trend of water treatment in China is that the practice of mainly introducing equipment has gradually shrunk, and domestic equipment is rapidly emerging. At the same time, by optimizing the configuration to make the configuration more humane, environmental, and modern, this is a symbol of the modernization of water treatment, a guarantee for saving engineering investment, reducing energy consumption, and reliable operation.
After years of efforts, China's technical specifications, standards, and designs in the field of water treatment equipment have gradually reached program and standardization. It is believed that after the efforts during the "Eleventh Five-Year Plan" period, the overall technical level of China's water treatment equipment will certainly reach the international advanced level.
