摘要
大型水生植物在水污染治理中有着积极作用,能通过物理的作用(如植物根系会分泌含特殊的功能团的有机物,吸附、过滤和沉淀水中的化合物),化学的作用(直接吸收和利用可利用态氮、磷,以及从周围环境中交换吸附重金属等),微生物的辅助作用达到净化水质的效果。因此大型水生植物将成为很有前途的综合处理污水的新生力量。
Macrophytes have positive roles in water pollution treatment. Firstly, through the physical functions, macrophytes can purge the polluted water. For example: The root of macrophytes can excrete special function groups that can absorb, filter and precipitate chemical compound of water. Secondly, through the function of chemistry, macrophytes absorb and utilize bioavailable N, P and exchange absorbtion heavy metals from the surrounding environment directly, etc. Third, through the auxiliary function of the microorganism, macrophytes can get the result of purifying water quality. So macrophytes will become promising force of comprehensive treatment sewage.
