纖維織物風管供應商給您講解自我凈(jing)化(hua)系統

自(zi)(zi)我凈(jing)化(hua)系(xi)(xi)(xi)(xi)統(tong)(tong)是(shi)指對環境(jing)污(wu)染(ran)物(wu)(wu)(wu)有一定(ding)程度自(zi)(zi)凈(jing)消(xiao)納能力的(de)(de)(de)(de)系(xi)(xi)(xi)(xi)統(tong)(tong)。是(shi)環境(jing)污(wu)染(ran)物(wu)(wu)(wu)經過(guo)農業土壤(rang)(rang)和(he)植(zhi)(zhi)物(wu)(wu)(wu)、微(wei)生(sheng)物(wu)(wu)(wu)的(de)(de)(de)(de)物(wu)(wu)(wu)理、化(hua)學(xue)及(ji)生(sheng)物(wu)(wu)(wu)作(zuo)(zuo)用(yong)，在不超出環境(jing)容量的(de)(de)(de)(de)前提下，自(zi)(zi)我凈(jing)化(hua)的(de)(de)(de)(de)農業生(sheng)態綜(zong)合體(ti)。土壤(rang)(rang)-植(zhi)(zhi)物(wu)(wu)(wu)系(xi)(xi)(xi)(xi)統(tong)(tong)是(shi)個自(zi)(zi)然活(huo)過(guo)濾器(qi)，凈(jing)化(hua)功能的(de)(de)(de)(de)機制是(shi):植(zhi)(zhi)物(wu)(wu)(wu)根系(xi)(xi)(xi)(xi)與(yu)葉面的(de)(de)(de)(de)吸收(shou)、轉化(hua)、消(xiao)解與(yu)合成(cheng);土壤(rang)(rang)微(wei)生(sheng)物(wu)(wu)(wu)的(de)(de)(de)(de)降(jiang)解、轉化(hua)及(ji)生(sheng)物(wu)(wu)(wu)固定(ding)作(zuo)(zuo)用(yong);土壤(rang)(rang)膠體(ti)的(de)(de)(de)(de)吸附(fu)、絡(luo)合和(he)沉淀作(zuo)(zuo)用(yong);土壤(rang)(rang)的(de)(de)(de)(de)離子交(jiao)換作(zuo)(zuo)用(yong)、機械(xie)滯留及(ji)氣體(ti)擴散作(zuo)(zuo)用(yong)。對于不同污(wu)染(ran)物(wu)(wu)(wu)質，土壤(rang)(rang)-植(zhi)(zhi)物(wu)(wu)(wu)系(xi)(xi)(xi)(xi)統(tong)(tong)的(de)(de)(de)(de)凈(jing)化(hua)機理、強度和(he)過(guo)程也不相(xiang)同;其(qi)生(sheng)態結構不同，對污(wu)染(ran)物(wu)(wu)(wu)的(de)(de)(de)(de)凈(jing)化(hua)效(xiao)率也不一樣。這些因(yin)素(su)是(shi)構成(cheng)個具體(ti)系(xi)(xi)(xi)(xi)統(tong)(tong)環境(jing)容量的(de)(de)(de)(de)基礎。如利用(yong)土壤(rang)(rang)凈(jing)化(hua)污(wu)水已有100余年(nian)歷史;利用(yong)水生(sheng)植(zhi)(zhi)物(wu)(wu)(wu)凈(jing)化(hua)污(wu)水，生(sheng)態效(xiao)益和(he)經濟效(xiao)益均十分顯著。
