Description
Technical Field
The invention belongs to the technical field of oil-water separation, and particularly relates to oil-water separation and recycling integrated equipment for treating oily sewage.
Background
The oily sewage is mainly discharged from the petroleum exploitation and processing process, the steel smelting process and the catering industry. Because water resource protection is more and more strict, under the condition that the wastewater discharge standard is improved year by year, the treatment difficulty of the oily wastewater is more and more high, the cost is continuously increased, and even partial enterprises face the embarrassment of closing because the wastewater cannot be treated.
At present, the domestic treatment of oily sewage mainly adopts the methods of air floatation, gravity separation, flocculation, filtration and the like. The oil removal rate by air flotation and gravity separation is generally not more than 70%, the efficiency is low, and the occupied space is large. The flocculation method has poor treatment effect on free grease contained in the sewage, and a flocculating agent needs to be additionally added, and secondary filtration and separation are needed after flocculation. The filtering method has higher grease removal rate on oily sewage, but has more strict requirements on filtering materials, and different filtering materials have larger difference in filtering effect, and the common filtering materials at present comprise quartz sand, clay, walnut shells, fiber balls and the like. The quartz sand has the characteristics of high strength, high density and strong dirt carrying capacity, but the labor intensity is high when the filling material is loaded and unloaded, and the subsequent adsorption is difficult to treat. The walnut shell and fiber ball filter material has the advantages of light weight, good filtering effect and the like, and is concerned by researchers and producers. For example, the wangxoujun of Zhonghai oil in 2016 introduced the filtering effect of the modified walnut shell filtering material, and Yanyuting in Liaohe oil field in 2019 made a relevant study on the walnut shell filter. The research on the application of the modified fiber ball in the deep treatment of offshore oilfield sewage is carried out by the Tang Guangrong of the Zhonghai oil, and the research shows that the modified fiber ball has good filtering effect.
The currently reported filtering means and technologies are all to treat oily sewage as three wastes, and a lot of equipment is designed according to different fillers, for example, utility model CN208726837U, a filter with backwashing function is designed, for example, CN208120905U reports a filter convenient for sewage filtering and sterilization. CN208161112U reports a multistage fiber filter. These filters have good filtering effect, but have two disadvantages: firstly, the back washing process needs intermittent operation, namely, the back washing can be carried out only after the filtration is stopped; secondly, the filtered grease is not collected in all filtering methods of the filtering equipment. Crude oil, distillate oil, lubricating grease, edible oil and the like contained in the oily sewage are valuable resources, and if the oily sewage can be effectively recovered, the pollution can be reduced, and the energy can be saved by resource utilization.
