You should spend about 20 minutes on this task. The diagram below shows how a modern landfill for household waste is designed. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.
The illustrations above show the transversal surface of a
landfill
, and they also
display how to process household waste
with the landfill
.
The design of the landfill
evidently takes into consideration the stability of the landfill
. Additionally
, the design effectively balances the need to dispose of household waste
and protect the environment.
In the construction phase, workers dig out a hole
which is supported by natural rocks to ensure stability. The wall of the hole
is lined with clay and synthetic lining in order to prevent leachate from contaminating the surrounding soil. Moreover
, there are drainage pipes at the bottom of the hole
, which directly lead to a drainage tank for storing waste
liquid.
During the use process, workers cover the hole
with a layer of clay after trucks dump household waste
into it. Due to
gases produced during waste
decomposition, ventilation pipes are inserted into the clay cover to release gases from decomposition.Submitted by hx88375757 on
