Xinji Creates "Green Leather" To Strengthen The Investigation Of Sewage Related Enterprises

Xinji, known as "jinshulu" since ancient times, how will Xinji plan for the future development of the city after it is directly under the jurisdiction of the province?

The answer was given at the third session of the Eighth People's Congress of Xinji City, which closed on February 21.

"Further increase support for industrial upgrading and enterprise development, accelerate the development of industrial chains and industrial clusters, strive to build a new industrial system, and comprehensively improve the quality and efficiency of industrial economic operation." In the "government work report" written by mayor balikai of Xinji, industry has become the main hand to strengthen the scale and strength of the city. Xinji has a history of 100 years Leatherwear Industry is expected.

It is understood that this year, Xinji will adhere to the "new" and vigorously transform and upgrade the leather industry. Leather, the most dynamic characteristic traditional industry in the local area, will radiate new vitality.

　　 Iron hand pollution control, pull net to check all sewage related enterprises

On March 1 this year, the "water pollutant discharge standard for leather and fur processing industry", which is known as the "strictest" in China, will be implemented soon. In an interview with the media, the person in charge of the Department of science and technology standards of the Ministry of Environmental Protection said that about 45% of small enterprises will face the fate of elimination.

"Sewage treatment is the lifeline for Xinji leather to achieve sustainable development." On the morning of February 21, mayor of Xinji, Mr. balikai, came to the point in an interview. He believes that to transform and upgrade the leather industry, we must first break the dilemma brought about by the increasing environmental constraints.

According to this idea, Xinji city "government work report" clearly put forward "to strengthen water pollution control".

According to the relevant person in charge of the Management Committee of Xinji tanning Industrial Zone, in order to solve the problem of tannery wastewater treatment, Xinji has initiated a three-level treatment system in the domestic leather industry, including primary treatment of enterprises, centralized professional treatment of tanning areas, and final comprehensive treatment of urban sewage treatment plants. In order to control the pollution from the source, Xinji has determined that the scale of the tanning area will not be expanded any more. Meanwhile, the existing enterprises in the park will be checked by means of network. All the production enterprises with serious pollution and low added value of products will be removed.

"This year's main task is to do a good job in pollution control and upgrading in tannery areas." Balikey told the author. According to the deployment of Xinji city's "government work report", tannery enterprises' self built or joint construction of sewage treatment facilities and tannery sewage treatment plant and water collection pipe network transformation will be completed and put into operation before the end of September this year, which will fundamentally solve the problem of tannery sewage treatment.

According to the author's understanding, there are 106 enterprises in Xinji leather industrial zone, and 30 sewage treatment plants have been built by themselves.

The upcoming "water pollutant discharge standard for leather and fur processing industry" stipulates the water pollutant emission limits, monitoring and monitoring requirements for leather and fur processing enterprises, and focuses on controlling the indicators of characteristic pollutants such as total nitrogen and chloride ions. As a matter of fact, the leather industry has a large amount of pollutant discharge and complicated sewage composition. According to the public data, leather, fur, feather and their products and processing shoes The total chromium emission of the industry ranks second in all industries.

　　 Facing the severe situation, how does Xinji deal with it?

Balikai told the author that relying on the academician workstation set up by Shi Bi of the Chinese Academy of Engineering in Dongming group, Xinji compulsorily promoted 13 new technologies and new processes with international leading level, such as recycling of chromium liquor and alkali liquor, ash free expansion and water-saving drum. The water consumption of leather making was saved by more than one-third, the sludge was reduced by 80% compared with the past, and the chromium liquid, alkali liquor, water-saving drum and other new technologies were promoted The discharge of alkali liquor was reduced by 70%. Xinji also actively promoted the chrome free tanning production process in leather enterprises, and chrome free tanned leather accounted for more than 85% of the total leather“ Xinji is striving to build a real green leather industry.

Circular economy has also become one of the breakthrough points for Xinji to explore the transformation and upgrading of leather industry. In the southeast of Xinji City, the project of comprehensive utilization of sludge resources has been broken. The project, with an investment of 160 million yuan, is invested and built by Shanghai Ruihui company. The sludge produced in Xinji leather industry is deeply dehydrated, dried and incinerated. The thermal energy generated from incineration is used for power generation. The ash from sludge power generation is used to make industrial culvert and brick products, solidifying the heavy metals in it and realizing zero emission of pollutants“ Now it seems that the development of circular economy with new technology and new technology will not only increase the environmental protection cost of enterprises, but also bring economic benefits to enterprises. More importantly, it has boosted the vitality of our leather industry. " Balikai's excitement was obvious.
