Wastewater treatment equipment filter

Wastewater treatment equipment filter is essential to human survival and development of resources. Industrial water is about 80% in industrial cooling water, water circulating water accounted for a large proportion in the total amount, so the wastewater treatment equipment filter circulating water system becomes more important. Filter of equipments in the petroleum and chemical industry wastewater treatment in order to improve the concentration ratio of circulating water as the main direction of water saving, under high concentrated multiple operation modes, to filter water dosing system and wastewater treatment equipment automatic control system has a higher request, conventional extensive dosing and control mode will not be able to meet the requirements.

due to the high alkalinity water supplement which may lead to a waste water treatment equipment filter circulating water enrichment ratio is low, the factory has been control in 2. 5 times the following, the circulating water amount is large, large amount of drug dosing, cooling water treatment cost is very high, in order to reduce the amount of circulating water meet the requirements of sinopec corporation circulating water treatment technology indicators, in August 2007 to develop a practical scheme of adding acid. To the circulating water system with concentrated sulfuric acid to reduce the pH value of the system, and automatic control is realized by using on-line instrumentation, so as to realize the circulating water system under high concentration ratio and stable operation, and ultimately achieve the goal of water-saving efficiency. Start adding acid to the circulating water system control of pH value, water treatment agent change, improve the concentration ratio of circulating water, achieve the goal of water saving and emissions reduction.

industrial cooling water as one of the main part of industrial water is thermal power, metallurgy, oil refining, chemical and other industries essential for production process conditions. Especially in oil refining chemical enterprise production operation, it take away excess heat generated in oil refining chemical production, cooling, the cooling process of medium, and meet the requirements of production process and safe storage and transportation, at the same time, make the production stream heat and high temperature environment of the equipment or parts for cooling, to meet the requirements of the equipment running smoothly, thus in the oil refining chemical production, the stand or fall of cooling water system of water quality in production of 'long, steady, Ann, full,' operation is of great significance.

open circulating cooling water system, cooling water after and process heat exchange medium, it is exposed to air cooling through the cooling tower and cooling pool and are cooled, and then by circulating water pump to get hot water device returns to the system of recycling, because the system has can save a lot of fresh water, reduce emissions, prevent heat pollution, and the system is relatively simple, in the operation of the heat flow is larger, management is convenient wait for a characteristic, therefore got very extensive application in industrial enterprises. Golmud refinery located in golmud in the northeast qinghai-tibet plateau, at an altitude of 2800 m, is the world's highest one million tons refinery, now has atmospheric pressure. Catalytic cracking. Reforming hydrogenation. Gas fractionation polypropylene and methanol refining and chemical industry more than 10 sets of equipment.
