Xinji Leather Industry: Transformation And Upgrading; Gorgeous Rebirth

Ever since Heavy pollution Industry, to today's clean production, circular development, Hebei Province Xinji After the baptism of pollution control and transformation and upgrading, the city's leather industry is like Phoenix Nirvana Generally, they are rejuvenated. According to statistics, from January to May this year, Xinji leather industry achieved sales revenue of 8.8 billion yuan, a year-on-year increase of 92.98%.

"If it is not adjusted in time, the economic development model will encounter the limit of growth due to the change of factors. To break this bottleneck, only adhere to green development. " Xinji municipal Party Secretary Zhang LIANGANG said with deep feeling.

　 Implement the five unified operation mode

Building a comprehensive pollution control platform

The tannery enterprises in Xinji tanning industrial zone are one after another, and the city sewage treatment plant of Xinji city is next to these tannery enterprises. At the main outlet of the municipal sewage treatment plant, we can see the sewage treated by multiple procedures Clear and transparent It doesn't smell bad.

Such water quality, in Xinji City leather enterprise vigorous development at the beginning is very difficult to see. According to the data, there were more than 800 tannery enterprises in Xinji City in 1994, most of which were workshop type. The production wastewater was directly discharged, and the water was dirty and smelly, which caused serious pollution to the surrounding environment.

Sewage treatment is the lifeline of leather industry to achieve sustainable development. In the tanning Industrial Zone, Xinji city has implemented the "five unified" operation mode of "unified planning, unified pollution control, unified water supply, unified electric heating and unified management". This model has set up a development platform for centralized production, comprehensive pollution control and scale operation of tanneries, and guided and attracted all local tanneries and some foreign tanneries to build factories in the district. At present, there are more than 80 enterprises in the tanning Industrial Zone, with an annual output of 36.5 million pieces of leather, making it the largest sheep leather base in Asia.

　　 Carrying out the three-level governance system

Ensure the discharge of sewage up to standard

In order to solve the problem of tannery wastewater treatment, Xinji city initiated a three-level treatment system in domestic tannery industry, including primary treatment of enterprises, centralized professional treatment of tanning areas, and final comprehensive treatment of urban sewage treatment plants. Now, the tannery wastewater here has reached 3% of the standard, and the water quality of the exit section has reached the national level for a long time emission standard 。

Behind the gratifying achievements is the strong support of management mechanism innovation. Xinji City stipulates that when the COD concentration of effluent from wastewater treatment plant in tannery area is less than 500mg / L, tannery District Management Committee will cash the fee according to the agreement; If the effluent exceeds the standard, the funds shall be deducted accordingly, and the emergency plan shall be initiated to investigate the responsibility of the plant director and relevant personnel. When the COD concentration of the effluent of the municipal sewage treatment plant does not exceed 100mg / L, the Municipal Finance shall allocate the funds for the WWTP on time; When the COD of effluent exceeds 100mg / L, the wages of some employees will be deducted from the funds allocated by the municipal finance, and the emergency plan will be started. The chemical oxygen demand of inlet and outlet water is calculated according to the daily average value and calculated at the end of each month.

At the same time, Xinji city strengthened the research on source control and recycling utilization of leather making. Relying on new technology and new equipment, the water consumption of leather making was saved by more than 1 / 3, the tannery sludge was reduced by 80%, and the discharge of chromium and alkali liquor was reduced by 70%. At present, the new technology of water-saving drum has been applied in 10 tannery enterprises, and the water-saving rate reaches 60%. Chrome free tanned leather accounts for more than 85% of the total leather, which has become a real "green leather".

Xinji tanning industrial zone has become the only tannery base with centralized pollution control, unified management, the largest scale, the best product quality and the best pollution control effect in China.

　　 Speed up propulsion technology innovate

Enhance the ability of pollution prevention

In the face of the achievements made in the leather industry, there is no time to be excited and celebrate. Standing at the starting point of the "Twelfth Five Year Plan", Xinji people put down their achievements and honor, and set off again and again with the mentality of returning to zero.

This year, Xinji city has stepped up the promotion and application of a number of new cleaner production and recycling processes and technologies to comprehensively improve the ability to prevent pollution in leather making; After the completion of the sludge power plant with an investment of 160 million yuan, all the sludge generated from tannery will be recycled for power generation; With the new technology introduced, all the chrome mud produced in leather making will be recovered, and then the chromium powder can be extracted through professional production line. The imported high and new technology with an investment of 70 million yuan will recycle and process leather which was previously regarded as waste.

"In international sales, there are strict admission standards for regional pollution index and product environmental pollution index. The prosperity of our leather manufacturing industry is closely related to the implementation of ecological protection measures. " Xinji leather industry zone management committee responsible comrades said.

According to reports, at present, Xinji city is embarking on the implementation of major projects such as the second phase project of International Leather City, leather clothing industry headquarters base and cleaner production demonstration park, striving to achieve a sales revenue of 25 billion yuan and 30 billion yuan by 2015. The transformation of Xinji leather industry is becoming wider and wider.
