Research Rationale Vietnam development follow path of industrialization - modernization, so there should be focused on the construction and development of infrastructure. To satisfie this requirement, the construction plays an important role in that renewal. In which cement is an important material in which most countries in the world to use in building works. Cement industry in our country are qualified to develop, because our country is rich in raw materials (limestone, clay) and have the conditions of access to the most advanced technology.
Tan Quang cement factory was Tan Quang Cement Joint Stock Company investment officially went into operation in January, 25th 2011 in Tuyen Quang city with a capacity of 2500 tonnes clinker / day, equivalent 910000 tonnes of cement products PCB40 / year. Tan Quang cement factory in operation marked a new development of industrial Tuyen Quang, simultaneously contributing to the objectives of the Government on development of cement industry Vietnam until 2020, bringing the industry Vietnam cement industry to become a strong industry, with modern technology, capable of competing on the domestic market and internationally. However, beside the positive aspects achieved, we are facing many environmental problems. Wastewater from the production process and wastewater of officials and employees have risk of causing environmental pollution.
Therefore, the evaluation of the performance of wastewater treatment in the sewage treatment of Tan Quang cement factory belong Tan Quang Cement Joint Stock Company helps us have a look overall level of impact on the environment. 4 Stemming from this fact, the consent of International Training and Development Center - Thai Nguyen University of Agriculture and Forestry, under the direct guidance of Dr. Nguyen Thanh Hai, I studied the topic “Assessing performance the wastewater treatment of Tan Quang cement factory, Tuyen Quang province ".

Environmental concept Environmental concept: According to the Law on Environmental Protection Vietnam 2005 chapter 1, article 3: “Environmental include factors natural and artificial material factors have close relationships with each other, surrounded humans, affects life, produce, the existence and development of man and nature” (Ministry of Natural Resources and Environment, 2005). The living environment of human according to function is divided into categories: Natural environment: include natural factors such as physics, chemistry, biology, exists beyond the control of humans, but also less affected by humans. It is sunlight, mountains and rivers, sea, air, animals, plants, soil, water. Natural environments gives us air to breathe, land to build houses, cultivated, breeding, gives people all kinds of mineral resources needed for production, consumption and impoundments, waste assimilation, give us beauty for recreation, to make human life more abundant.
Social environment: overall the relationships between people. Those are the laws, institutions and commitments, regulations, assess. at different levels as: United Nations, Association of countries, country, province, district, organization, village, clan, family, groups, religious organizations, mass organization,. Social environment oriented activity of human follow a certain framework, creating favorable collective force for development, making the lives of other human beings with other living organisms.
7 Artificial environment: including all physical factors, biological, social by humans created and influenced by man made comforts in life, such as cars, planes, houses, offices, the urban areas, parks artificial. Function of environment: - Environment is a living space for humans and animals world. - Environment is where contain resources necessary for life and human production. - Environment is the place to contain the waste created by humans in the process of living.
- Storage function and provide information to people. - Protect people and animals from the effects of outside. Environmental standards: According to the Law on Environmental Protection Vietnam 2005: “Environmental standards are standards, permissible limits set forth to used as a basis for environmental management” 2. Concept of water sources Water is a chemical compound of oxygen and hydrogen, has 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 life. 70% of the Earth is water covered but only 0.3% of all water on Earth is in the source can be exploited used as drinking water. Fresh water is a renewable resource, however the supply of clean fresh water in the world is gradually reduced. Water demand has exceeded supply in some parts of the world, while the world population continues to increase as the demand for water is 8 increasing.
The awareness of the importance of protecting water resources to ecosystem needs to be only mentioned recently. During the 20th century, more than half of the wetlands in the world have disappeared along with the supportive environment of their value. Freshwater ecosystems bearing properties biodiversity is declining faster than marine ecosystems and land. Framework programs in locating water resources for domestic use objects known as the right to water.
Concept of water pollution - Water pollution is shift in the direction worsening of physical properties, chemical biology of water with the presence of strange substances in liquid, solid make water becomes toxic to humans and animals. Water pollution reduced 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 water flows through the surface 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 factory,the waste of hospital, household waste of human or chemicals, pesticides, organic fertilizers .
