Background technology
Leather industry is the pillar industry of China's light industry, now has become the industry with international competitiveness, China
The center of world's leather industry is had become, three big good reputations are enjoyed in the world：One is that stock number is big；Two be that yield is big；Three are
Foreign trade amount is big.Leather industry is the preponderant dinstinctive industry in Zhejiang Province, even more the pillar industry of Haining City and with competition
The specialty industries of advantage, leather has visually been described as " the golden business card " in Haining.But it should also be recognized that, leather industry belongs to tradition
Industry, can produce certain pollutant in process of production.Wherein, the dye thing produced in tanning production is very big in leather industry
Pollution, be also one of the subject matter for perplexing leather industry development.
It is mainly four kinds of organic nitrogen, ammonia nitrogen, nitrite nitrogen and nitrate nitrogen in leather-making waste water, in the process of tanning production
In each workshop section can produce certain waste water, but each workshop section's Determination of Total Nitrogen in Waste Water concentration distribution is uneven, and differs greatly, and has
There is certain fluctuating range.Mainly there are two aspects in the source of total nitrogen in leather-making waste water：One is that leather making process is various animals
The mechanically and chemically processing procedure (containing biochemistry) of raw hide, animal raw hide contains substantial amounts of collagen in itself, and it can be in process hides water
Itself discharges substantial amounts of organic nitrogen in factory's each operation；Two be that chemicals containing ammonia nitrogen is also added in leather making process, is predominantly taken off
The ammonium sulfate added in ash and softening workshop section.But for many years, the various waste water in being produced for leather are handled, finally all
Good effect is not obtained, suppresses the development of leather industry yet.
