lignin in paper mill waste water can be polymerized

and then processed to give high quality water treatment

coagulator. Besides, ordinary domestic sludge disinfected by

radiation becomes more fertile, yielding about 20% more

in crops (e.g. maize).

6.

The use of wastes in waste treatment. The radiation

source of caesium -137 commonly used in radiation

treatment is itself a kind of radioactive waste. If

this waste is extracted for use as radiation source,

the disposal of nuclear wastes and the objective of

environmental purification can be achieved at the same

time.
