Stop production Three months, invest about 20000000 to build a sewage treatment plant for any one of the main production of leather private enterprises, how to calculate it is a money losing account. Xie Kunpeng, director of the enterprise management office of the tannery Industrial Area Management Committee of Xinji, Hebei, told reporters that when he first received the task to persuade the large enterprises in the tannery park to build their own sewage treatment plants, many heads of enterprises were unwilling to do so.

"Time means money for these private enterprises. However, the new system introduced in the city requires large tanning enterprises not to engage in production and operation without building sewage treatment plants, which will enable enterprises to take action. Xie Kunpeng said.

Xinji is 65 kilometers east of Shijiazhuang, 250 kilometers from Beijing. Although the geographical location is not very prominent, this small city is an important leather production and marketing center in China. It has more than 1000 leather enterprises, and 3000 sheepskin garment leather products each year, accounting for 50% of the domestic similar products, accounting for 15% of the world's similar products, and 400 sheepskin garments each year, accounting for 30% of the similar products in China, and about 12000000 kinds of leather products each year.

　　 however The amount of sewage discharged from leather industry is also huge. Insiders believe that the new standard of leather industry has come to an urgent task. China is the largest leather manufacturing country in the world, and the export of leather goods has been ranked first in light industry for many years. However, the leather industry is characterized by a large amount of sewage and complex sewage components. According to the 2012 annual report on environmental statistics, the total chromium emissions of leather, fur, feathers and their products and footwear industry are about 74 tons, ranking second in all industries, accounting for 39.2%.

In March 1, 2014, the Ministry of environmental protection issued the "discharge standard for water pollutants in leather and fur processing industry". The standard specifies the limits of water pollution discharge, monitoring and environmental impact assessment, and the design of environmental protection facilities for tanning and fur processing industries. This standard is known as "the most stringent standard in leather industry history".

In early 2014, the Xinji municipal government asked large enterprises to build sewage treatment plants themselves, and small and medium-sized enterprises jointly built sewage treatment plants, otherwise the enterprises would be closed. At present, 28 sewage treatment plants have completed civil works, and equipment is being installed. After the completion of the project, the local tannery area has formed the three stage treatment mode of the enterprise sewage treatment plant, the tannery sewage treatment plant and the municipal sewage treatment plant.

　　 Dong He Xiang It is the manager of a local tannery enterprise. From the father's family, the family was engaged in leather business. Up to now, the company has 6 million leather and 5 million pairs of shoes. He felt that the technique of "making leather" had penetrated into the blood of his family. Speaking of workers in the past three months, working day and night to build a sewage treatment plant, he said: "in fact, production is also good, investment is also pretty good, but we rely on a line of people to eat not only to make money, but also to consider the cultural heritage. To protect and control the surrounding environment is the best way to inherit tanning culture in the long run.
