工業(yè)廢水中氮的來源有多種，例如印染廢水中的尿素、電鍍廢水中的氨水、鋼鐵行業(yè)中的硝xiao酸等等，這些物質的高占比使得氮元素在綜合廢水中的比例也隨之升高，這些行業(yè)的常規(guī)廢水站通常設置生物池，利用微生物的生理代謝來處理廢水中的氮元素，但是不同于生活污水，工業(yè)廢水并不適合微生物生長繁殖，不僅抑制菌類繁殖且會使微生物大量致死，使脫氮效果微乎其微。過去，人們不曾意識到氮元素有哪些危害，很多企業(yè)在處理廢水過程中并沒有真正正視脫氮的環(huán)節(jié)，導致水體惡化，藻類大量繁殖，魚yu蝦不斷死亡，水域環(huán)境惡化升級，在后續(xù)的研究中，人們發(fā)現(xiàn)，硝xiao酸鹽在人體中會轉化為亞硝xiao酸鹽，不僅會影響氧的傳輸能力，還會與蛋白生成亞硝胺這類強致ai物質，于是，人們開始重視廢水中氮的去除。
There are many types of the source of nitrogen in the industrial wastewater, such as ammonia urea in printing and dyeing wastewater, electroplating wastewater, xiao nitrate acid in the steel industry, etc., these substances high proportion makes nitrogen also will increase in the proportion of comprehensive wastewater, the industry of conventional wastewater treatment station usually set biological pool, use of microbial physiological metabolism to deal with waste water in nitrogen, but different from the domestic sewage, industrial waste water is not suitable for microbial growth, not only restrain bacteria breeding and will kill a massive, causes the denitrification effect. In the past, people never aware of the dangers of what are nitrogen, many enterprises in the process of wastewater treatment and no real denitrification in the face of link, leads to the deterioration of the water, algae blooms, yu, shrimp fish died, water environment deterioration upgrade, in subsequent studies, it has been found that xiao acid salt nitrate in the human body will be converted to the xiao nitrate acid salt, not only affect the oxygen transfer ability, will also with protein generate nitrosamines such strong material to ai, so people began to pay attention to the removal of nitrogen in the wastewater.
在化學脫氮法、電滲析法、離子交換法、催化氧化法、反滲透法、生物脫氨法中，去除硝酸鹽廣泛使用的是生物脫氮法，生物脫氮法是將廢水進行物化預處理后通過微生物在好氧、厭氧條件下的不同生化反應，將硝態(tài)氮還原為氮氣的過程。
In the chemical denitrification method, electrodialysis method, ion exchange method, catalytic oxidation method, reverse osmosis, a biological ammonia method, is the most widely used to remove nitrate biological nitrogen removal method, biological denitrification method will be materialized after pretreatment wastewater by microorganism in aerobic and anaerobic conditions of different biochemical reactions, the nitrate reduction process for nitrogen.
生物脫氮法以其成熟的工藝、低廉的運行成本、較好的處理效果等優(yōu)勢在國內外的廢水脫氮處理中占據主流位置，但生物脫氮法也存在一定的缺陷，如：生物掛膜難、富集慢；?對工業(yè)廢水耐受力差；?反應器的局限性使脫氮負荷低；?生化占地面積較大；?多個反應池組合造成結構復雜；?脫氮效率低，需較長停留時間等。
Biological denitrification has occupied a mainstream position in wastewater denitrification treatment at home and abroad by virtue of its mature technology, low operating cost and better treatment effect. Poor tolerance to industrial wastewater; The limitation of the reactor makes the denitrification load low. Biochemistry covers a large area. The combination of multiple reaction pools resulted in complex structure. The denitrification efficiency is low and the residence time is long.
