Abstract:

The environment is where people live and work. So, the environment has been a

serious problem of society. It is not only a problem of a country but also is a global

problem. It requires that we must take action to protect the environment. One of the

most of the sources of pollution influence on the environment is that waste-water

including domestic waste-water and industrial waste-water.

Currently, the development of science and technology have helped human

achieve the great achievements in the fields of social life. Besides, speed socio￾economic development increasingly more advanced. Industrialized socialization

entails not only economic growth but also the causes of increasing amounts of waste

increase. In addition, the amount of municipal waste, waste from agricultural by

production generated in large quantities when the harvest season. All this trash had the

common characteristic is that it was unclassified.

In Vietnam, every day, big cities and urban areas in the country have over

9100m3 of waste discharged including the amount of municipal waste more than

75.4%, the rate of collection is only about 40%-50% and it is pre-treated. The

collection and treatment of solid waste is not thorough causing negative impact on the

environment: stinks, pollution of surface water, underground water, soil pollution,

pathogens and the spread of disease...

Industrial Thai Nguyen Iron and Steel were the main supplier for market about

raw materials in steel industry. Besides, the steelmaking process also releases large

amount of waste causing environmental pollution. So, through the process “Assessing

the performance of waste-water treatment in Luyen Thep factory-Thai Nguyen Iron

and Steel Join Sock Corporation”. From there, we can give some solution appropriate

to deal with minimize the environmental pollution problem in factory.

Key words Performance treatment, rain-water overflowing, domestic

waste-water, industrial waste-water, processes treatment.

ACKNOWLEDGMENTS

Practice is the participatory process to learn, observe, study and manipulate

application of knowledge learned into practice the work of environmental management

of the factory.

Internship report is an opportunity for students to present on issues of their

interest in the course of practice, as well as an important document to help teachers

examine and evaluate the learning process and results practice of each student.

To complete this internship report during practice at Luyen Thep Luu Xa

factory-Thai Nguyen Iron and Steel Join Sock Corporation. I wish to express my

thanks to:

- Associate Professor - Dr. Do Thi Lan lecturer of Environmental Science - Nong Lam

University direct teacher's guide me in this internship. She instructed during practice

and build reports.
