Upgrading Of Leather Sewage Treatment Equipment In Mexico To Achieve Recycling

< p > Mexico's a href= "//www.sjfzxm.com/news/index_c.asp" > raw material < /a > skin resources are very rich. It is an important raw material production base in the world.

According to statistics, there are 64 million livestock stocks in Mexico, of which more than half are cattle.

Sufficient livestock raising and abundant raw leather resources have made Mexico's tannery and a target= "_blank" href= "//www.sjfzxm.com/" > shoes < /a > industry developing rapidly. It has become one of the world's ten largest a target= "_blank" href= "//www.sjfzxm.com/" leather less than the largest producing country, and its production accounts for more than 1/4 of the world's total production.

< p > leather products industry including knapsack, handbag, luggage, belt and leather "a" target= "_blank" href= "//www.sjfzxm.com/" > clothing < /a > is located in leather industry. After that, it is the second largest leather production industry in Mexico.

In the 32 states of Mexico, Jalisco and Guanajuato two states are important tanneries and shoemaking industrial zones.

Jalisco is a shoemaking industrial area. It is made up of 1200 small factories. It mainly produces < a href= "//www.sjfzxm.com/news/index_c.asp" > women's shoes < /a > leather products.

Guanajuato is a combination of leather making, shoes making and related industries, with a radiation area of 15 square kilometers, 300 shoe parts manufacturers, 620 "a href=" //www.sjfzxm.com/news/ "> tanneries" > /a > (Mexico 76% registered tanneries concentrated in this area), 1500 shoe factories and 356 leather factories, which belong to one of the largest leather processing areas in the world.

< p > in Mexico, Leon has 500 or so large and small tanneries. The sewage discharged by a large proportion of tanneries seriously affects the local environment, because tannery is the industry that produces a lot of sewage. < a href= "//www.sjfzxm.com/news/" > tannery sewage < /a > not only is large, but also a complex and high concentration organic waste water. It is a kind of industrial wastewater which is difficult to control.

In tanning production, due to the different raw material, processing technology and finished products, the quality of sewage is quite different. Due to the use of a lot of degreasing agents, fatliquoring agents and surfactants in the tanning process, sewage is treated by conventional aeration aerobic activated sludge process, resulting in a large number of bubbles, and the activated sludge will run away with the foam.

High concentration organic wastewater, chromium and other heavy metal wastewater treatment is difficult, resulting in heavy pollution in the leather industry.

< p > the SAPAL leather sewage treatment company in Leon, Mexico, invested six million US dollars to improve the equipment, and invited the tanneries to visit the most advanced sewage treatment equipment.

Its chairman, Peder Gonzalez Garcia, said that this would bring economic benefits to Leon, a small town called a href= "//www.sjfzxm.com" and tannery industry < /a >, and the environment will not be affected.

The goal of SAPAL leather sewage treatment company is to make 100% recycling of these tannery sewage in production.

At present, the project has been completed by about 40%. In early 2014, the improved equipment will be put into full use.
