纖維織物風管供應商給您講解自(zi)我(wo)凈(jing)化系統

自我(wo)凈化(hua)系(xi)(xi)統(tong)是指對(dui)(dui)環(huan)(huan)境(jing)污(wu)染物(wu)(wu)(wu)(wu)有一定(ding)程(cheng)度自凈消(xiao)納(na)能力的(de)(de)系(xi)(xi)統(tong)。是環(huan)(huan)境(jing)污(wu)染物(wu)(wu)(wu)(wu)經過(guo)(guo)農業土壤(rang)(rang)和(he)(he)植(zhi)物(wu)(wu)(wu)(wu)、微生(sheng)物(wu)(wu)(wu)(wu)的(de)(de)物(wu)(wu)(wu)(wu)理、化(hua)學(xue)及(ji)生(sheng)物(wu)(wu)(wu)(wu)作(zuo)(zuo)用(yong)，在不(bu)(bu)超出環(huan)(huan)境(jing)容量的(de)(de)前提下，自我(wo)凈化(hua)的(de)(de)農業生(sheng)態(tai)綜合(he)體。土壤(rang)(rang)-植(zhi)物(wu)(wu)(wu)(wu)系(xi)(xi)統(tong)是個自然活過(guo)(guo)濾(lv)器，凈化(hua)功能的(de)(de)機制是:植(zhi)物(wu)(wu)(wu)(wu)根(gen)系(xi)(xi)與(yu)葉面的(de)(de)吸收、轉化(hua)、消(xiao)解與(yu)合(he)成;土壤(rang)(rang)微生(sheng)物(wu)(wu)(wu)(wu)的(de)(de)降解、轉化(hua)及(ji)生(sheng)物(wu)(wu)(wu)(wu)固定(ding)作(zuo)(zuo)用(yong);土壤(rang)(rang)膠(jiao)體的(de)(de)吸附、絡合(he)和(he)(he)沉(chen)淀作(zuo)(zuo)用(yong);土壤(rang)(rang)的(de)(de)離子(zi)交換作(zuo)(zuo)用(yong)、機械滯留及(ji)氣體擴散作(zuo)(zuo)用(yong)。對(dui)(dui)于不(bu)(bu)同(tong)(tong)(tong)污(wu)染物(wu)(wu)(wu)(wu)質，土壤(rang)(rang)-植(zhi)物(wu)(wu)(wu)(wu)系(xi)(xi)統(tong)的(de)(de)凈化(hua)機理、強度和(he)(he)過(guo)(guo)程(cheng)也(ye)不(bu)(bu)相同(tong)(tong)(tong);其生(sheng)態(tai)結(jie)構不(bu)(bu)同(tong)(tong)(tong)，對(dui)(dui)污(wu)染物(wu)(wu)(wu)(wu)的(de)(de)凈化(hua)效(xiao)率也(ye)不(bu)(bu)一樣(yang)。這些因素是構成個具體系(xi)(xi)統(tong)環(huan)(huan)境(jing)容量的(de)(de)基礎。如利用(yong)土壤(rang)(rang)凈化(hua)污(wu)水(shui)已有100余年歷史;利用(yong)水(shui)生(sheng)植(zhi)物(wu)(wu)(wu)(wu)凈化(hua)污(wu)水(shui)，生(sheng)態(tai)效(xiao)益和(he)(he)經濟效(xiao)益均十分顯著。
