使用 Agilent 4200 MP-AES 分析生活污泥

Managing the treatment and disposal of domestic sludge is an important
activity and one that is highly regulated in many countries. After treatment,
the effluent may be discharged leaving a mixture of water, organic solids
and chemicals, nutrients, heavy metals, and inorganic ions. This sludge can
be further treated and the resulting biosolids can then be applied to the
land as a fertilizer, sent to
landfill or incinerated. It is vital that the sludge
or biosolids are tested and conform to regulatory levels in order to protect
public health and the environment.
The United States federal biosolids rule is contained in 40 CFR Part 503. The
European
Union Sludge Directive 86/278/EEC is expected to be revised as
several Member States have enacted and implemented stricter limit values
for heavy metals and set requirements for other contaminants.
