Sewage treatment is an important issue
in a country for public health and environmental protection. The
treatment process not only consumes energy but also emits CO2. In
this research, the idea of streamlined life cycle assessment was
applied. The CO2 emission from sewage treatment was assessed from direct
energy consumption of four major sewage treatment plants in Taiwan.
The results showed that the CO2 emission at in-plant sewage treatment
stage takes more than 95% of total CO2 emission
for most plants. The results suggested that CO2 emission
of sewage treatment can be calculated from energy consumption at
in-plant sewage treatment stage to simplify the calculation. The
CO2 emission
of sewage treatment was then assessed from sewage plants in Taiwan
using in-plant electricity consumption. The unit CO2 emission
of sewage treatment in Taiwan is 0.216 kg-CO2/m3.
This database will be an important reference for water resource
research and future government environmental policies. Keywords: CO2 emission;
life cycle assessment (LCA); sewage treatment ABSTRAK
Rawatan kumbahan merupakan isu yang
penting dalam negara untuk kesihatan umum dan perlindungan alam
sekitar. Proses rawatan ini tidak hanya menggunakan tenaga tetapi
juga membebaskan CO2.
Dalam kajian ini, idea kitaran hidup yang diselaraskan telah diaplikasikan.
Pembebasan CO2 daripada rawatan kumbahan telah dinilai daripada penggunaan
tenaga langsung daripada empat pusat rawatan kumbahan yang utama
di Taiwan. Keputusan menunjukkan bahawa pembebasan CO2 di
peringkat dalam pusat rawatan kumbahan merangkumi 95% daripada jumlah
pembebasan CO2 di kebanyakan pusat. Keputusan mencadangkan bahawa pembebasan
CO2 daripada rawatan kumbahan dapat dikira daripada penggunaan
tenaga di peringkat dalam rawatan kumbahan untuk memudahkan pengiraan.
Pembebasan CO2 daripada rawatan kumbahan kemudiannya
dinilai daripada pusat kumbahan di Taiwan melalui penggunaan elektrik
dalam pusat. Unit pembebasan CO2 daripada rawatan kumbahan di
Taiwan adalah 0.216 kg-CO2/m3. Pangkalan
data ini akan menjadi rujukan penting untuk kajian sumber air dan
polisi alam sekitar kerajaan pada masa hadapan. Kata kunci: Kitaran hidup yang dilaraskan; pembebasan CO2; rawatan kumbahan RUJUKAN Burton,
