In the east corner of the production area of Jianfeng Health Technology Company, there is a very inconspicuous building. From below, only a few pipes with uneven thickness can be seen on the top and the slogan "Focus on Environmental Protection and Promote Sustainable Development" with red letters on the yellow background on the stainless steel guardrail. Walking up, you can only see several closed pools and a small room with stacks of documents, test tubes, glass bottles and other testing tools on the table. This is the peak and healthy sewage treatment station. The production sewage of the whole factory area is concentrated here. After adjustment (PH adjustment), pre-acidification, anaerobic, anoxic, aerobic (aeration), precipitation and other links, it is discharged into the pipe network after reaching the special discharge standard. Yin Zhiwu, executive deputy general manager of

Jianfeng Health, said that since the sewage treatment station in Wucheng District has not been built, Jianfeng Health has not yet been able to realize pipe discharge, while relevant national laws have strict requirements on the discharge of water pollutants from the extracted pharmaceutical industry, and sewage discharge must meet special discharge limits, the chemical oxygen demand (COD ) must be below 50 mg / L.

Pay equal attention to enterprise development and environmental protection is the concept that Peak Health has always adhered to since its establishment. In July of this year, on the basis of the original environmental protection facilities, Jianfeng Health carried out technical renovation of waste gas collection and treatment facilities. At the same time, a sealing cover was added to the sewage treatment station to realize the closed collection of waste gas. Since the trial operation of this facility 5 in mid-September, the overall effect has been obvious. The original treatment tank would emit an unpleasant smell during work, but now the smell has been significantly reduced.

Compared with the young enterprise of Peak Health, the relatively "older" Peak Pharmaceutical has more experience in sewage treatment and environmental protection. The main products of Qiubin Pharmaceutical Factory are injections, ear drops and eye drops. There are no high concentrations of chemicals in the production sewage. Therefore, the original sewage treatment station only needs to collect the production sewage together with the domestic sewage into the collection tank, neutralize it through acid and alkali, and then discharge it into the urban sewage pipe network after reaching the tertiary discharge standard through a series of treatments such as anaerobic tank and aerobic tank.

At the beginning of 2016 , according to the arrangement of the pharmaceutical company, the product development department moved into Qiubin factory, where the small and pilot tests of product research and development were carried out. For this reason, Qiubin Factory has carried out renovation and upgrading of sewage treatment facilities. The high-concentration waste liquid collected in the experiment is regularly sent to companies with relevant qualifications for treatment. The waste water generated by washing bottles and tanks at ordinary times enters the regulating tank for treatment through pipelines. The toxic and harmful gases produced during the experiment are also treated by the new waste gas treatment tower and discharged after meeting the atmospheric emission standards. According to the requirements of the environmental protection department, the sewage pipes of the whole plant have also been changed into open channels. "In the event of a leak in an underground pipe, it often takes a lot of time and effort to investigate, which is not conducive to regulation and will also extend the pollution control time. After the change to an open channel, all the pipes are clear at a glance, which can detect problems in a timely manner and also facilitate the supervision of environmental protection departments." Sheng Junyong, an environmental member of the production department of Qiubin Factory, explained the reason for the establishment of the open channel.

As the latest and largest drug production base of Jianfeng Pharmaceutical, Jinxi Pharmaceutical Factory, which was completed and put into operation in

2015 , has inherent advantages in environmental protection. Each workshop is equipped with a pretreatment tank. The high-concentration sewage is discharged into the collection tank after pretreatment. After a series of treatment processes, it is discharged after reaching the third-level discharge standard and is included in the municipal sewage pipe network. There is also an emergency pool in the sewage treatment station. If the treated sewage does not meet the discharge standard or there is an emergency, the treated sewage will be discharged into the emergency pool first, and then returned to the collection pool for treatment before discharge.

The sewage treatment station of Jinxi Pharmaceutical Factory consists of two buildings. One building is a closed treatment tank, connected by various pipes, and two cylindrical exhaust gas collection devices stand in the middle. Another building is equivalent to an operation room, one part of which is adjusted by the sewage treatment station staff through relevant equipment, using

PAC , PAM , ferrous sulfate and other chemicals to adjust the PH value of sewage, and the other part is the environmental protection bureau's pollution source online monitoring system. Zhang Baoping, deputy director of

Jinxi Pharmaceutical Factory, said that the new environmental protection law has strict requirements on the discharge standards of pharmaceutical manufacturers. During the construction of the sewage treatment station, Jinxi Pharmaceutical Factory actively requested the environmental protection department to install online monitoring facilities to monitor the sewage standard discharge outlet in real time, effectively avoiding the discharge of excessive sewage. At present, the daily wastewater treatment scale of the sewage treatment station can reach

700 tons. In terms of tail gas and solid waste treatment, Jinxi Pharmaceutical Factory has a tail gas incinerator and collection device, a special solid waste storage facility, and entrusts a unit with relevant qualifications to carry out regular treatment to avoid pollution to water and soil.

If the facilities and equipment are perfect, whether they can really play a role depends on people in the end. Jianfeng Health and Pharmaceutical Company attach great importance to daily environmental management, and carry out energy conservation, emission reduction and environmental protection treatment through various means such as technological improvement, process optimization and equipment upgrading. To strengthen testing, the staff of the sewage treatment station will test the water sample

PH value of the water outlet every day, and 1 - 2 times of COD content testing every week, ensure that sewage is discharged up to the standard; set up special personnel to be responsible for the investigation and supervision of environmental safety hazards, treatment and operation management of pollution treatment facilities, and conduct environmental protection assessment; organize relevant personnel to learn environmental protection related laws and regulations from time to time, so as to consciously abide by them in production and operation; sign safety and environmental protection responsibility letter every year, decompose and implement it to each team and individual, and clarify their respective responsibilities; implement clean production technology to reduce pollutant discharge, production arrangements to increase production volume, improve product yield, energy saving and consumption reduction.

In 2016

, the project of Jinxi Pharmaceutical Factory passed the environmental protection acceptance, and the two pharmaceutical factories of Qiubin and Jinxi passed the cleaner production review and environmental system certification, and the environmental protection facilities were operating normally. Every year, Jianfeng Pharmaceutical invests a lot of money in the renovation of environmental protection facilities and regular maintenance. The environmental behavior level of the enterprise has been rated as green (excellent environmental behavior) for several consecutive years. Peak health is also actively doing a good job in environmental protection acceptance, and strive to complete the overall environmental protection acceptance before this year 10 .

This year, Zhejiang sounded the clarion call of "eliminating inferior

V water" in the first year of the year, and issued the "Zhejiang Province's Action Plan for Eliminating inferior V water". Six major projects have been deployed to tackle key problems, including sewage interception and receiving pipes, river dredging, industrial regulation, agricultural and rural non-point source control, discharge port regulation, ecological water distribution and restoration, vowing to completely eliminate inferior V water in 2017 . Through various measures such as the investment of environmental protection equipment, the construction and implementation of daily environmental protection management system, Jianfeng Health and Jianfeng Pharmaceutical have ensured the long-term stable discharge of various pollutants up to the standard, and helped to eliminate inferior V water with practical actions.
