Hebei Xinji Leather Sludge Has Its Place.

Recently, Jing Chai and his "under the dome" occupy the headlines of all kinds of layout. Almost overnight, the whole nation is about Jing Chai's dribs and drabs. The origin of haze is closely related to environmental pollution. During the two sessions, environmental pollution has become a common concern.

　　 Sludge treatment It has always been a difficult problem, especially tannery sludge, which is the source of many environmental problems and food safety problems.

It is understood that the comprehensive utilization of sewage sludge in Xinji project was awarded in May 2014. Hebei Provincial Development and Reform Commission formally approved. In 2015, it was listed as one of the ten key environmental protection projects in Hebei province. It can handle about 500000 tons of sludge with 85% water cut every year, which can effectively solve the problem of leather sludge pollution in Xinji, the capital of leather goods.

about To curry leather At present, sludge disposal is basically directly disposed of after simple dewatering treatment, which takes up a lot of farmland, and the two pollution problem is serious.

In order to solve this problem, Hebei has developed an integrated sewage and sludge innocuous comprehensive treatment technology by using the self-developed R & D patent technology of screw type sludge dewatering machine and the national invention patent "closed semi dry sludge treatment process", which has solved the technical problems in the process of sludge treatment, such as dehydration, incineration, power generation, desulphurization and denitration, and removal of peculiar smell.

In addition, Hebei state Hui adopts the self-developed low energy consumption deep dehydration technology, which can deeply dehydrate the sludge produced by the sewage treatment plant, and use the heat generated by the sludge in the treatment process to generate electricity. Finally, the burnt sludge ash will be made into industrial culvert, brick and other products to solidify the heavy metals contained in the sludge.

However, the meaning behind traditional handicraft is hard to be replaced, so is leather shoes. Thomas Keil is one of the few handcraftsmen who can insist on making hand-made leather shoes, and also set up their own workshops.

Thomas Keil is a hand-made leather shoe maker from Germany. In his studio, we can see every link in the production of hand-made leather shoes. His great grandfather used to be a leather shoemaker, and this handicraft once withered after his death. Years later, Thomas Keil decided to reclaim hand-made leather shoes and let his great grandfather's spirit and skills continue. Before he set up his own studio, he learned from a Hungarian leather shoe maker and built his own leather shoes production studio in Hamburg through continuous learning and practice.

When we walk into the studio of Thomas Keil, we can see an old workbench, a stool, and an old leather sofa. He loved this traditional handicraft very much. Before every production, he carefully measured the size of each foot, and then made shoes and soles on the shoe last. The production of each pair of shoes takes about three months. During this period, you can pick the color you like and look at the shoes you are looking forward to for a long time.
