In production, industrial enterprises will inevitably produce sewage. How to resist pollution and achieve a win-win situation for economic benefits and ecological environment is not only related to the long-term development of the enterprise, but also related to the happy life of future generations. We can't just have Jinshan and Yinshan, we must have green water and green mountains, and green water and green mountains are Jinshan and Yinshan.

Boda, focusing on the special microbes and membrane technology of "Double Plus Clean", has conducted technical research on oilfield wastewater, and formed a proprietary technology of "microorganism + low energy consumption tubular membrane", which has low investment costs, good effluent water quality, and sludge volume. The characteristics of low and no secondary pollution provide a new way for oilfield wastewater treatment. At present, the project has penetrated into more than 20 oil production plants in more than 10 domestic oilfields, conducted more than 30 field tests, and completed more than 20 This industrialized application project has an ideal treatment effect, so it has received high attention and unanimous praise from China National Petroleum Corporation, Sinopec and other major oilfields.

Recently, Jilin Oilfield also announced that after half a year of operation, the effluent quality has met the design requirements and reached the "5.1.1" standard, and even exclaimed that Broad technology can turn corruption into a miracle. This indicates that this technology will be widely promoted and applied in the development of low and ultra-low permeability reservoirs in Jilin.

The incoming sewage enters the buffer tank, the effluent enters the degreasing tank, and the effluent from the degreasing tank enters the microbial reaction tank to fully degrade the oil and organic matter in the sewage. The effluent from the reaction tank is pressurized into the membrane filtration system, and the effluent reaches the reinjection water quality index. Water injection system.

The key to this link is the microbial reaction tank and membrane separation

Then how do they "bath" the large amount of sewage?

Broad "Microbe + Membrane" oilfield produced water treatment process is called "a technological revolution in oilfield sewage treatment". It organically combines microbial treatment technology and membrane separation technology. It is used to add Boda’s unique "double plus clear" obligate combined flora in oily sewage, and through competition with microorganisms in sewage to form a dominant flora, quickly establish a A system that effectively degrades organic pollution such as benzene, hydrocarbons, and lipids in petroleum wastewater, and then degrades complex organic matter such as sludge into simple inorganic matter through a series of complex processes such as hydration, activation, and oxidation. The product is water And carbon dioxide. Obligate microorganisms use organic pollutants in sewage as nutrients and obtain energy to realize the metabolism of their own life and achieve the purpose of purifying sewage.

In May 2014, the "microorganism + membrane separation" pilot plant entered the Jilin Oilfield site. After more than two years of commissioning at the stage of indoor test and pilot test, repeated comparisons, research and deliberation, and optimization of the process. In early 2016, This technology was applied in the reconstruction project of the sewage treatment system of Jilin Oilfield. The design made full use of the existing equipment and facilities, saving the project investment of about 3 million yuan; after the device was put into operation on October 18, 2016, it can be recovered by recycling crude oil and saving Coagulants, fungicides and other medicaments can reduce power consumption and obtain direct economic benefits of 1,995,800 yuan per year.

After the application of "microbe + membrane separation" technology, it not only effectively reduces the formation damage caused by water quality, improves the water flooding effect, but also provides sufficient water source for the oilfield water injection development, opening a new era of low-permeability produced water technology in Jilin Oilfield .
