Shanxi Changzhi Clearance Solution for Leaking Aniline Pollution is Unclear

Changzhi, January 9th, January 9th, Shanxi Changzhi Tianji coal chemical aniline leakage accident has entered the 10th day, in the leakage accident in the aniline tank area sewage outlet, the middle of the interception of pollutants Huangniou reservoir, sewage pipe into the muddy In the Weihe River Drainage, the relevant departments and enterprises involved in the work of manpower put activated carbon, transfer of pollutants back to the factory processing, in order to eliminate pollution, but the reporter found that the company involved in the event of accidents will be discharged after the accident to the factory site about 3 kilometers deep from the factory Ditch.

In response to the subsequent pollution control in the polluted areas and the lower reaches of the Chaoyang River, the enterprises involved have not announced a complete set of treatment plans. Many reporters asked the local government and enterprises that they have not received a clear response.

The company involved in the production of sewage continues to drain into nearby trenches

On the 8th, the reporter saw outside the fence of the Tianji Coal Chemical Industry Group's aniline tank area where a leakage accident occurred. The staff of the Tianji Coal Chemical Group is cleaning the ice from the sewage outlet and throws away activated carbon to adsorb pollutants. According to the introduction of Tianji workers, the aniline tank numbered as a leakage accident is V620B, with a rated capacity of approximately 3,000 tons.

According to the Tianzhu Chemical "1231" Incident Handling Working Group, it was reported at 8:00 pm on the 6th that: After the accident occurred on December 31, 2012, the Changzhi City Government and the company immediately initiated an emergency plan and ordered the company to stop production immediately.

On the 8th, the reporter saw Tianyuan Group, a manufacturer of aniline, seeing that many facilities are still in production and operation, and the factory staff also admitted that they are still producing.

Along the Tianji Group sewage drain all the way forward, from time to time can see lime, activated carbon and other scattered river. About 2 kilometers from the Tianji plant area, the reporter found that the sewage discharged from the plant site was intercepted here, and then flowed to the southwest deep trench through the pumping station pipeline. Approaching the ditch, sewage buzzed across the mountains and pungent odors rushed. At noon, the sewage that passes through the mountains evaporates to form mist.

Guided by local villagers, the reporter turned away to the sewage accumulation point. It is roughly estimated that sewage has formed a funnel-shaped “sewage lake” with an area of ​​tens of thousands of square meters, and the lake emits a pungent odor. Looking ahead, the mixture of sewage and fly ash turned grayish-brown and there were fresh excavated traces on the cliffs around the lake. In addition to the occasionally flying birds on the side of the Sewage Lake, there were no people on the site.

According to local villagers, after the aniline leak accident occurred, the Tianji Group sent staff to block the sewage drains and discharged the sewage into the deep trench to form a “sewage lake”. Prior to this, the sewage flowed through the drainage channels to the Zhuoyu River all the year round, and the villagers along the route were deeply affected.

On the morning of the 9th, in Wangduzhuang, a town in Weizi City, Fuzhou City, an old man added sheep and sheep. A few years ago, the Tianji Group had sent people to inform farmers along the drainage canal that they should not allow their animals to drink canal water because the livestock’s drinking water caused casualties. conceited. Since then, the villagers along the way have always been far away from the drainage channel.

It is understood that the “Sewage Lake” is located between Wangduzhuang and Sanjing Village in Handan City. Before the incident, the local area had been excavating fly ash from the lake. Recently, the Tianji Group dispatched people to set up warning signs on the road leading to the "sewage lake," reminding the public that "ditches are dangerous and no ditching is prohibited."

Is effluent discharged into the "sewage lake" containing aniline contamination? Will long-term savings of sewage contaminate and pollute groundwater? What are the follow-up measures? These have yet to be further investigated and announced by relevant departments.

Cleaning work will start or will last for a long time

Shanxi Tianji Chemical's “12·31” accident disposal working group notice said that after initial verification, the total amount of aniline leakage from Shanxi Tianji Group was approximately 38.7 tons. Among them, 30 tons of aniline were intercepted by the use of the Huang Niu Qiangan Reservoir, and about 8.7 tons of aniline was discharged into the Zhuoyu River.

Previously, according to the “People's Daily” report, Liu Dashan, chief engineer of the Environmental Protection Department of Shanxi Province, said that because aniline is insoluble in water and its density is slightly heavier than water, it will have a certain impact on the river sediment. The local area has begun to fully clean up the rivers through which the contaminated masses pass, and the cleaned up sediment will be further harmlessly treated.

When the Shanxi Tianji Chemical "1231" Incident Handling Working Group passed a number of press conferences, indicating that the water quality in the lower reaches of the Zhuozhang River has generally improved, the people naturally turned their attention to the harmless treatment of contaminated areas.

On the 9th, in Yongcheng Huangniu Reservoir where 30 tons of aniline was intercepted, the staff of the Tianji Group and its parent company Luan Group are working intensively on the icy lake.

The reporter saw at the lake, under the frozen lake, the rust-red pollutants are faintly visible. The staff in the uniform of the Pan'an Group set up planks on the lake, cut ice caves, and put bags of activated carbon underwater.

It is understood that the Huangniu Reservoir has not stored water for many years. It only stored floods and floods during the rainy season. Local villagers planted food in the reservoir all year round.

The on-site decontamination personnel said that they received cleaning notices from the higher authorities, mainly through activated carbon adsorption of aniline residues, and then transported the activated carbon package away for harmless treatment. As for the adsorption of pollutants after the activated carbon package shipped to where? What is the harmless treatment? The on-site staff is unknown.

On the Lake District side, two Tianji Group workers are pumping water under the ice. The involved workers introduced that they were on duty 24 hours a day. Sewage flows through the underground pipeline to the front of the reservoir dam, and is then transported back to the factory for disposal by fire trucks and Tianji Group's own tankers.

According to reports, because the density of aniline is slightly heavier than water, it will naturally settle to the bottom of the reservoir. Therefore, the sediment treatment along the polluted area along the way may be prolonged.

It is roughly estimated that the sewage coverage area of ​​Huangnihoe Reservoir is about the size of six or seven football fields, with water depths ranging from half a meter to one meter. Faced with such a huge amount of sewage, on-site workers do not know when it will be able to handle it.

As of the 9th, Tianji Group has not yet released a plan for remediation of polluted areas. Little is known about the harm of aniline pollution by villagers along the way. The reporter has repeatedly contacted the relevant departments of Changzhi City, Tianji Group and other units and has never received a positive response. (Finish)
