Firstly, Construction activities that give to air pollution include land clearing, the operation of diesel engines, machinery, transportation, burning, and working with toxic materials. All construction sites generate high levels of dust (typically from concrete, cement) and this can lead to large distances over a long period of time.
Therefore, the project owner needs to plan for air pollution remediation from the start of construction planning to the completion of the plant. This will minimize the impact on the environment and the people.
Second, through the process of finding out about processing technology of air pollution in the production process of concrete in Vietnam and other developing countries in the world, pointed out the weaknesses in the processing of air pollution in Vietnam. Currently, in Viet Nam, most of the companies in the concrete industry apply the technology as stated. But the technology used in the factories in Viet Nam is still limited and not yet have much experience in operating the latest technology in the world. Therefore, we need to learn more experiences in developed countries in the application of technology to minimize contamination of the environment. One of the most important issues in Vietnam is that the cost of a pollution treatment system is very expensive, so we do not have enough money to import the best processing technology in the world. But now Viet Nam is gradually improving the processing of air pollution. The Government has also paid attention to the issue of air pollution, reviewed and setting standards, laws, technical improvements, support policies for air pollution treatment technology to apply in the process of managing and processing of
air pollution in Viet Nam and towards a future of economic development that does not affect the environment.
4.2. Lesson learned
During graduation internship at Bac Giang Center For Monitoring Resources and Environment with the original goal is to learn more knowledge to be able to apply in practical work. This is a very professional working environment and has helped me to learn a lot of knowledge beyond my expectations. The first thing that impressed me the most was that everyone's attitude towards their work was very serious, which is something that everyone needs to learn. Because in work, we need to have the passion, an attitude to work really seriously can help us to improve the knowledge of themselves and complete the work in an excellent way. Initially, in the process of becoming acquainted with the work, the equipment used in the environmental analysis also quite new to me. But with the help of the people in the Center and the actual survey trip in some companies that have helped me learn more knowledge outside my majors, understand more about active processes in the production, the processing system sources of environmental pollution and the use of environmental analysis equipment to monitor, analyze and synthesize the current state of environmental quality. From that establishes environmental impact reports, proposals and recommendations the prevention solution to minimize environmental pollution. That's the invaluable knowledge for me.
CHAPTER V. CONCLUSION AND RECOMMENDATIONS
With results analyzed 3 samples: water, air, land. It can be seen that the results of the analysis had pointed out was the quality of the environment in the area before building the plant generally is relatively good. Measurable indicators are lower than the limit specified by the Ministry of Natural Resources and Environment, however water environment, there is a number of substances exceeding the prescribed as Chloride (exceeds 6.41 times), COD (exceeds 1.06 times), total suspended solids (exceeds 1.56 times), NH4 (exceeds 1.65 times), DO (lower than the limit allows 1.04 times) and Coliform (exceeds 3.2 times) should be overcome.
During the construction and production phase. The concentration of pollutant emissions of vehicles and generators is much lower than the standards set by the Ministry of Natural Resources and Environment. That of NO2 emissions in machinery equipment exceeds 3.25 times the prescribed level. If the project owner complies with the air pollution protection plan mentioned above, it will not harm the air environment.
The above is the entire contents of the internship report with the subject:
“Assessing the air environmental quality during the construction and operation phase of Bac Giang concrete factory”.
During graduation internship at Bac Giang Center For Monitoring Resources and Environment of Bac Giang Natural Resources and Environment Department. I have understood how to manage and handle the air pollution in the construction and production process of Bac Giang Concrete Production Factory.
In this thesis, I used the knowledge learned in school and tried to present the basics of the process handle of air pollution. Learn lots of new knowledge as active
processes in the production process, the source systems that cause environmental pollution and the use of environmental analysis equipment to monitor, analyze the environmental quality status.
Recommendation:
Project owners should take the following measures:
+ In coordination with the State management bodies and the specialized agencies to perform control, monitoring the current state of the environment of the plant.
+ Carry out periodic environmental control as specified. Results of analysis and measurement of environmental quality will be stored for comparison and control, and submitted to state management agencies for monitoring.
+ Manage, supervise the construction and operation of the mixer machine in order to comply with the approved technical design, closely monitoring the condition of the machinery to minimize noise and emission impacts.
+ Inform employees about regulations and guidelines for occupational safety and environmental protection. Regular control and strict implementation of the provisions and instructions.
+ Regularly monitor the work: cleaning work, waste treatment and emissions.
