Wastewater treatment equipment filter element

The filter element of wastewater treatment equipment is an indispensable resource for human survival and development. About 80% of industrial water is industrial cooling water, and circulating water accounts for a large proportion of the total water consumption. Therefore, the circulating water system of the filter element of wastewater treatment equipment is more important. At present, the main direction of water saving is to increase the concentration ratio of the circulating water of the waste water treatment equipment of petroleum and chemical enterprises. Under the operation mode of high concentration ratio, there are higher requirements for the dosing system and the automatic control system of the circulating water of the waste water treatment equipment. Extensive dosing and control methods will not meet the requirements. Due to the high alkalinity of the supplementary water, the concentration ratio of the circulating water in the filter element of the wastewater treatment equipment is low, which has been controlled below 2.5 times since the establishment of the plant. In order to reduce the discharge of circulating water and meet the requirements of Sinopec's circulating water treatment process indicators, in August 2007, a feasible acid addition plan was formulated. Add concentrated sulfuric acid to the circulating water system to reduce the pH value of the system, and use online instruments to realize automatic control, so as to realize the stable operation of the circulating water system under high concentration ratio, and finally achieve the purpose of water saving and efficiency improvement. Start to add acid to the circulating water system to control the pH value, replace the water treatment chemical formula, increase the concentration of circulating water, and achieve the purpose of water saving and emission reduction. As one of the main components of industrial water, industrial cooling water is an indispensable process condition for the production and operation of thermal power generation, metallurgy, oil refining and chemical industries. Especially in the production and operation of refining and chemical enterprises, it takes away the excess heat generated in refining and chemical production, so that the process medium can be cooled and condensed, so as to meet the requirements of production technology and safe storage and transportation, and at the same time make the equipment in production heat and high temperature environment. Or the components are cooled to meet the requirements of stable operation of the equipment. Therefore, in the refining and chemical production, the quality of the cooling water system is of great significance to the 'long, stable, safe, full and excellent' operation of the production. In the open circulating cooling water system, after the cooling water exchanges heat with the process medium, it is cooled by the cooling tower or cooling pool in contact with the air to dissipate heat, and then sent to the water device by the circulating water pump for heat and then returned to the system for circulation. Because the system can save a lot of fresh water, reduce the amount of sewage, prevent thermal pollution, and the system is relatively simple, the heat flow is large during operation, and the management is convenient, so it has been widely used in industrial enterprises. Golmud Refinery is located in Golmud in the northeastern part of the Qinghai-Tibet Plateau, with an altitude of 2800m. It is the world's highest one million-ton oil refinery. Now it has more than 10 sets of oil refining including atmospheric pressure, catalytic cracking, reforming hydrogenation, gas fractionation polypropylene and methanol. chemical plant.
