Classification of water treatment equipment
Water treatment equipment mainly includes structures, mechanical equipment and electrical and automatic control equipment. According to industry practice, water treatment equipment is mainly divided into general machinery equipment and special machinery equipment.
General machinery and equipment mainly include: water treatment fans, water treatment valves, water treatment water pumps, etc .; special machinery and equipment mainly include pollution control equipment, sludge and sand removal machinery and equipment, sludge treatment equipment, biogas utilization equipment and dosing, Disinfection equipment, etc. With the popularization of reclaimed water reuse, the application of membrane technology and equipment has become more and more widespread. The development of electrodialysis, reverse osmosis membranes and related mechanical devices is imminent; post-sludge disposal is the key equipment for the development of the water treatment industry in the next few years. Among them, transportation, turnover, drying, deodorization machinery and devices are the focus of development.
According to the industry standard HJ / T11-1996 "Classification and Naming of Environmental Protection Equipment", water treatment equipment can be divided into physical treatment equipment, chemical treatment equipment, physical and chemical treatment equipment, biological treatment equipment and combined water treatment equipment. Each of these categories is subdivided into many smaller categories.
The development of China's water treatment equipment industry is inseparable from the development of China's environmental protection industry. The production of domestic water treatment equipment began in the mid-to-late 1970s. At that time, the standardization, completeness, and serialization of products were very low, and there were fewer stereotyped products. Since the beginning of the 1990s, the production level of special equipment for urban water treatment and supporting general equipment has been greatly improved.
According to incomplete statistics, there are about 4,000 special water treatment equipment manufacturing enterprises in China, mainly concentrated in Jiangsu and Zhejiang, accounting for about 70% of the total number of similar enterprises in the country.
In order to speed up the standardization of water treatment equipment. Relying on the Environmental Product Standardization Committee and the Water Treatment Equipment Sub-Technical Committee that have been approved by the National Standards Commission, the current industry standards are organized and standardized, and the national standards for key water treatment equipment are formulated as soon as possible to improve the status quo of multiple standards in parallel and produce for enterprises Provide the basis for quality supervision with the government.
