Trang 1EVALUATION OF THE PERFORMANCE
OF THE DOMESTIC WASTEWATER TREATMENT
AT TAN THUAN PORT
By Group 3
Trang 2As the knowledge about anthropogenic impacts of climate change has grown, the awareness of the contributions from treatment of wastewater has widened the scope for wastewater treatment plants / system
Not only shall ever stricter effluent constraints be met, but also energy efficiency be increased, greenhouse gases mitigated and resources recovered All under a constant pressure on costs
The main objective of this presentation has been to EVALUATION OF THE
PERFORMANCE OF THE DOMESTIC WASTEWATER TREATMENT AT TAN THUAN PORT
maybe to improve processing system to increase processing efficiency of the system and to reuse the water output for washing vehicles / machines at the port

RECOMMENDATIONS
Trang 131 Output of wastewater reaches QCVN 40:2011/BTNMT
Column B
2 Tan Thuan port only work from Monday to Friday, not
enough nutrition for microbes used to processing
3 The sewage pipeline is located in the drainage ditch
must monitor regularly to avoid leakage
CONCLUSIONS
Trang 141 Improve processing system to increase processing
efficiency of the system It is possible to reuse the water output for washing vehicles / machines at the port
2 Need to add nutrition to Aro-tank in days without
workers
3 It is advisable to move the pipeline to bring
wastewater out of the drainage ditch
