Do Thi Lan 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 i 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.

According to the forecast of world economic organizations, Vietnam will be one of the countries had speed of economic rapid development in the world and it is forecast to be 7% in the next decade. However, the economic growth quickly and strongly will also create pressure challenge impact to come environment.
After over 30 years of implementing the process of industrialization and modernization, Vietnam has industrial zones, export processing zones and high-tech zones in 57/64 provinces, attracting tens of thousands of construction projects plant with all sorts of career. Besides, producing a large volume of products to serve the domestic demand and exports, industrial establishments also consumes a huge amount of natural resources and energy, and emissions into the environment the corresponding amounts of waste (liquid, gas, solid and sludge). Inside, waste-water is often issue most concerned because it often has heavy traffic, pollution concentrations highly and contaminated components difficult to handle. Iron and Steel Industrial Zone - Thai Nguyen is the important industrial area in the Northern of province.
The waste-water treatment here is an important step, which affects directly or indirectly the lives of neighboring residential areas, ecosystems and biodiversity. The performance evaluation of waste-water treatment at the plant of industrial Gang Thep - Thai Nguyen helps us have a look overall level of impact on the environment, propose some management measures, waste-water treatment to be better. 4 Under the guidance directly by Associate Professor - Dr. Do Thi Lan.
I studied the topic "Assessing the performance the wastewater treatment in Luyen Thep- Luu Xa factory-Thai Nguyen Iron and Steel Join Sock Corporation ". Research’s objectives -Determining the performance of wastewater treatment at Luyen Thep Luu Xa factory - Research situation of environment in factory. - Proposing solutions to increase efficiency of wastewater treatment to achieve effective highest wastewater treatment. Request of topic - Assessing the true state of the processor performance of the wastewater treatment zones at the plant and the environmental situation of the Luyen Thep factory.
- Propose solutions to increase efficiency of wastewater treatment. - The results of analysis of environmental quality parameters of water, compared to TCVN 40: 2013/ MORNE. Research question and hypotheses - What is an overview of Luyen Thep factory? - What is current research situation of wastewater in factory and Viet Nam? - What is formula of performance? - How is performance of the wastewater treatment? - What are possible management and technology solution to reduce water pollution of factory? 1. Limitations Thesis was conducted during 4 months from March 2015 to July 2015.
Thai Nguyen Join Sock Corporation has 25 factories. Each factory has many environmental 5 problems such as water, air, soil noise,…and this thesis just assesses problem of water pollution and water source can be from other places. So, the measuring results may not be completely accurate. Definitions Environmental concept: In fact, there are many different definitions of the concept of "environment" According to Vietnamese Dictionary: "The environment is a combination of factors outside of a certain system.
We impact on this system and identify common trends in the world, the environment of an object, or an event general external condition affecting objects and events ". The functions of the environment: - The environment is the living space for people and animals world. - The environment is the place to contain the resources necessary for the life and human production. - The environment is the place to contain the waste created by humans in the process of living.
- Functions for storing and providing information to people - Protecting people and organisms from external impacts. The concept of water: - Water is a chemical compound of oxygen and hydrogen. The chemical formula is H2O. With special physical and chemical properties (eg: bipolar, hydrogen bonding and abnormalities of specific weight), water is a very important quality in many branches of science and in the life, 70% of the area of the Earth covered by water, but only 0.3% of all water on Earth can be exploited for drinking.
6 Fresh water is a renewable resource; however, the supply of fresh and clean water in the world is gradually reduced. Demand for water has exceeded supply in some parts of the world, while the world population continues to rise as increasing water demand. The awareness about the importance of protecting water resources to ecosystem only been voiced recently. (Loan, 2005) The concept of water pollution: Water pollution: is change the worsening of physical - chemistry - biological of water, with the presence of strange substances in liquid, solid make water become toxic to humans, organisms and reduce biodiversity in water.
In terms of transmission speed and scale of the impact of water pollution is more worrying problem of land pollution. Water pollution occurs when surface water flows through domestic waste, industrial waste water, the pollutants on the ground and infiltration into groundwater. The phenomenon of water pollution occurs when toxic chemicals, pathogenic bacteria, viruses, parasites arising from various waste sources such as industrial waste from the manufacturing plant, the waste of hospital, domestic waste types of human or chemicals, pesticides, organic fertilizers. used in agricultural production.
They are pushed out of ponds, lakes, rivers, streams or seep into groundwater without being processed or too large volume beyond self-regulation and self-cleaning of all kinds of ponds, lakes, rivers and streams. (Tuan, 2013) Water pollution has natural origin: by rain, snowmelt, flooding, wind storms. or so active products of living organisms, including their corpses. Plants and organisms die which are decomposed into microbial organic matter.
A part will seep into the ground, then deep into the ground water, polluting the air or groundwater flow mixed in large lines water.
