Oily wastewater concept oilfield oily wastewater or sewage. Which is derived from oil and gas production process associated formation water output. In order to obtain qualified oil and gas products, water needs to be associated with the oil and gas separation, the separated water contains a certain amount of associated crude oil and other impurities, which contains a certain amount of water associated crude oil and other impurities called oily water. 2 oily wastewater treatment of oily wastewater process description [1] According to the wastewater treatment level and water quality requirements for different levels of treatment of oilfield wastewater treatment technology is usually divided, secondary treatment and tertiary treatment. Generally primary treatment belong to a preprocessing, secondary treatment can remove about 90% of biodegradable organic load of 90% to 95% of the suspended solids. However, it is difficult for the heavy metal poisons and biological degradation of organic nitrogen-carbon compounds and appear in biological treatment process, phosphorus is difficult to completely remove Dribbling vacuum filter manufacturers and will require tertiary treatment. Processing technology at all levels including gravity separation, coarse-grained, flotation, filtration, membrane separation and biological method such as a dozen methods. First, the secondary treatment is the use of worrying too much, sedimentation, flotation method to remove suspended solids in the sewage. Removal from Wastewater and minerals and most of suspended solids, oil and the like. The main methods include gravity separation, centrifugation, filtration, coarse-grained, and, biological treatment methods. Oil: oil oily water main method are: gravitational settling, physical chemistry, chemical coagulation method, coarse-grained, filtration, flotation, activated carbon adsorption, biological method, electromagnetic method. Due to the different requirements of different water quality and the depth of treatment, a degreasing method alone is difficult to achieve the intended purpose, so when in the field dribbling vacuum filter effect, several methods are used in combination. Tianxiang professional manufacturing TSF Series Super dissolved air flotation machine (vertical flow) Equipment: TSF series dissolved air flotation sewage processor of steel structure, its working principle is: the air pressure through the pump into the dissolved gas cylinders, 0.5 Mpa is forced under pressure dissolved in water, in the case of a sudden release of dribbling vacuum filter, dissolved air precipitated in water to form a large number of dense micro bubbles, suspended solids in the slow rise adsorption process, so that the density of suspended solids floating decline, to the removal of SS and CODcr purposes. The company's sewage treatment equipment is now widely used in sewage treatment industry at home and abroad disease relaxed standards, living quarters, food, medical, slaughter, glue, gelatin, chemicals, leather, textile, hotel, printing and dyeing, paper and other industries discharge or reuse.
