Jinling Petrochemical Wastewater Treatment Plant has become an ecological landscape

Sinopec News Network reported on August 16, local business personnel who came to learn about Jinling Petrochemical’s environmental protection experience.
They visited along the bank of the Yangtze River and walked into the east bank of the Binjiang River in the northeast corner of the company.
Attracted: a green lawn matches the rippling clear water of a pool; the small red pavilion occupies the C position of the pool group, accompanied by a group of koi in the pool every day, and it seems to be telling the water and The story of fish
.

This is not a park, but a sewage treatment plant of Jinling Petrochemical, a "backyard" where sludge sticks to the feet and smells people in the past
.

The lawn on the far north side of the road was originally the company’s sludge storage tank and sludge processing area.

The water in the pool is the purified water that is recovered from the sewage produced by petrochemical production after being technically processed, waiting to be reused here, and of course it has also made the home of koi
.

The company's total annual water reuse reaches more than 27 million tons, which is equivalent to the water volume of five Nanjing Xuanwu Lakes

The sewage produced in the petrochemical production process mainly includes salty sewage and oily sewage, so the sewage treatment plant is divided into two treatment systems for salty sewage and oily sewage
.

After the salty sewage "comes" from the device, it is processed in a "tank-in-tank" to remove oil, and then transported to the primary and secondary air flotation pretreatment, and then flows into the aeration tank for primary and secondary biochemical treatment.

The professional name of the tertiary biochemical device in these two systems is Ozone Catalytic Oxidation + Internal Loop BAF, which is currently a more popular advanced water control technology in the world.
It is the Sinopec "Clear Water and Blue Sky" project that was put into use in July 2017
.

The various water quality indicators of the sewage treatment plant have been greatly improved as a result.

　　From 2019 to early 2020, the company upgraded the water purification pool and the surrounding environment, added small pavilions in the pool, replaced fences, unified the exterior surfaces of surrounding devices, storage tanks, and equipment, and added A piece of grass and trees were created, and the peculiar smell treatment was implemented to form the "park" in front of the factory area
.

　　The company was born on the side of the Yangtze River and took care of the mother river and never let a drop of sewage drain into the Yangtze River
.

Committed to the recycling of water resources, in addition to the tertiary biochemical technology of the sewage treatment plant, the company also uses catalytic oxidation and double membrane technology to recycle more than 20 million tons of wastewater every year, reducing the water intake of the Yangtze River by more than 21 million tons
