摘要
本文阐述了污泥热水解产物中四种重金属以及其对植物生长的影响。结果表明,热水解过程中,Zn、Cu、Cd和Pb有84%～98%转移到固相中,并且在固相中主要以残渣态存在。污泥水解液促进了大豆生长,污泥则对大豆生长表现出抑制效果。
Effect of Metals（Zn,Cu,Cd,Pb）in sludge hydrolysis on the germination and growth of soybean seedling were studied.Results showed thatmetals mainly distributed in the residual fraction which reduced their transferability than that in sludge samples.The growth of soybean were prometed by the sludge hydrolysis liguid,and were restrained by the the sludge.
