Local residents: Antibiotic enterprises secretly discharge toxic wastewater.
According to the report of local residents in Jining City, Shandong Province, there has been a strong smell of medicine near the old canal, and it is suspected that some enterprises nearby secretly discharge or exceed the standard to discharge toxic wastewater.
The clues reflected by residents directly point to Shandong Lu Kang Pharmaceutical Co., Ltd. near the Old Canal, which is one of the four major antibiotic factories in China. Residents said that Lu Kang was suspected of illegally transporting high-concentration antibiotic wastewater by tanker, and provided the reporter with the tanker number: Lu R. K62 1. To know the source and destination of antibiotic wastewater, we must find the tanker for transporting wastewater before entering the factory for investigation.
The reporter stayed in Jining for 6 days and traveled all over the city. Finally, on the eighth night, the tanker reported by residents appeared.
Obviously, this is the place where big cars are concentrated. Before the reporter went in for a closer look, another same big tanker came out from the inside. The reporter decided to follow closely and did not go far. The driver of the big tanker chose a noodle restaurant to get off for dinner. The reporter also walked into this noodle restaurant and chatted with the driver. The driver said it was sewage from the car.
Lu Kang is suspected of illegally transporting high-concentration wastewater containing antibiotics.
The reporter found that there was more than one tank truck transporting sewage. According to the clue provided by the driver, Lu Kang Sewage Treatment Center is suspected of illegally transferring high-concentration wastewater.
In order to get the water sample of wastewater discharged from Lu Kang in time, the reporter found Jining Environmental Protection Bureau and went to Lu Kang Sewage Treatment Center for investigation overnight. Coincidentally, as soon as I entered the factory, I saw a tanker as big as the one I followed the night before parked next to the sewage pool. The person in charge of Lu Kang said it was transporting raw materials, but why did the truck transporting raw materials stop at the sewage treatment center? Under the reporter's repeated questioning, the enterprise environmental protection personnel finally admitted that they were discharging pollutants.
The reporter found in the computer records of the enterprise that many chemical plants and branches in Lu Kang delivered high-concentration sewage to Lu Kang Sewage Treatment Center, and the name, settlement price and distance of foreign sewage were recorded in this ledger every day.
The wastewater containing antibiotics finally enters Jining section of Beijing-Hangzhou Grand Canal.
According to the requirements of China's environmental laws and regulations, enterprise sewage must be treated on the spot. Obviously, Lu Kang has been suspected of violating the law by accepting sewage from foreign enterprises.
According to the internal data of Lu Kang Company obtained by the reporter, the foreign sewage received by Lu Kang accounts for about 1/3 of the total sewage volume of the treatment center, and the reception of high-concentration foreign wastewater has also been written into the important profit point of Lu Kang Company's annual summary. However, with so many different types of high-concentration sewage mixed together, can Lu Kang handle it well?
In Lu Kang Sewage Treatment Center, the reporter sampled and analyzed the sewage discharged by enterprises after treatment. After testing, the concentration of tetracycline antibiotics is 53.688 micrograms per liter, which is tens of thousands of times that of antibiotics in natural water.
It is understood that wastewater from Lu Kang Pharmaceutical Co., Ltd. containing a large amount of antibiotics will enter Jining City Sewage Treatment Plant. According to experts, there are no effective treatment measures for antibiotics in urban sewage treatment plants in China. In other words, the water containing antibiotics passes through sewage treatment plants, old canals and wetlands, and finally enters the Jining section of the Beijing-Hangzhou Grand Canal.
The emission data has been tampered with by third-party operating companies.
During the investigation in Lu Kang, an insider's "working note" which recorded the details of sewage treatment in detail caught the attention of reporters. In a work record of Tao Xiaohong, the stationmaster of environmental protection station of Lu Kang Pharmaceutical Co., Ltd., the reporter saw that in recent days, there were many records that the COD value exceeded 400 mg per liter. As Lu Kang is a national key monitoring enterprise, all emission data will be transmitted to Jining Environmental Protection Bureau in real time. However, when the reporter opened the environmental monitoring data platform of Jining Environmental Protection Bureau, it was found that these data only showed more than 0/00 mg per liter without exception. What happened?
Also in this work note, the reporter found the mystery: "the operating company has sealed the upper limit." It turned out that the third-party operating company responsible for transmitting data to the environmental protection department revised the data upper limit for the sewage treatment center. No matter what the actual processing value is in Lu Kang, the data sent to the environmental protection department will not exceed the standard! For example, records show that the actual data of ammonia nitrogen has exceeded 50 mg per liter, while the third-party operating company has sealed the upper limit of the data to 15 mg per liter.
It is understood that it is not a day or two for third-party operating companies to fabricate false data for enterprises. This cooperation of Hide and Seek has been going on for several years. Lu Kang thinks that the third-party operating company with good cooperation is Tongtai Environmental Protection Science and Technology Service Center, which is a subsidiary of Jining Environmental Protection Bureau. It is obviously illegal to openly falsify for enterprises like this.
In Tao Xiaohong's work notes, the reporter also saw such a record: "I stopped at 18: 30 last night because the Environmental Protection Bureau checked the smell, and then drove after being notified", "rencheng district Environmental Protection Bureau came to check, but the dregs could not get out". It turns out that the environmental protection bureau wants to check, and the enterprise will know in advance and be prepared.
It is precisely because of the lack of supervision that in the three bottles of water samples taken by the reporter in Lu Kang, except the chemical oxygen demand COD and ammonia nitrogen seriously exceeded the standard, the data of tetracycline antibiotic residues were 14684 ng/l, 53688 ng/l and 337 12 ng/l respectively.

The content of antibiotics in surface water samples is amazing.
Recently, the reporter, together with researchers from the State Key Laboratory of Water Environment Simulation and the Institute of Water Science of Beijing Normal University, found that the content of antibiotics was amazing, even in the tap water of Nanjing residents' homes.
From the end of 65438+ 10 to the beginning of 165438+ 10 this year, journalists and researchers went to Northeast China, North China, East China and other places to collect water samples around some drinking water sources, drains, pharmaceutical enterprises, livestock and poultry farms and other areas. Through laboratory tests, antibiotics were detected in these water samples. In the drainage ditch near Shenyang Antibiotic Factory, the value of 6- aminopenicillanic acid is as high as 178 ng/l, and the values of ampicillin and amoxicillin are also above100 ng/L. ..
Wang Jinsheng, vice president of the Institute of Water Science of Beijing Normal University, said that antibiotics were detected in some areas of major rivers in China, such as Haihe River, Changjiang Estuary, Huangpu River, Pearl River and Liaohe River. Among them, the Guangzhou section of the Pearl River is seriously polluted by antibiotics, and the contents of typical antibiotics such as dehydrated erythromycin, sulfadiazine and sulfadiazine are 460,209 and 184 ng/L, respectively, which are much higher than those of rivers in developed countries in Europe and America. Because many rivers are drinking water sources in cities, antibiotics have also been detected in drinking water in residents' homes.
In Gulou District, Nanjing, the reporter sampled and analyzed the tap water of residents. The results show that the content of amoxicillin is 8 ng/l, and the content of 6- aminopenicillanic acid is 65438 0 9 ng/L. In fact, it is not the first time that antibiotics have been detected in tap water. The College of Resources and Environment of Anhui Agricultural University has previously investigated some water bodies in Chuzhou, Anqing, Fuyang, Tongling, Bengbu and other cities in Anhui Province. In addition to 8 kinds of antibiotics in surface water and groundwater, 6 kinds of antibiotics such as tetracycline, oxytetracycline, chlortetracycline, doxycycline, sulfadiazine and sulfamethoxazole were also detected in tap water for residents to drink, with high content reaching 10.82 ng/l and low content.
