Nowadays, environmental pollution has become more and more serious in Vietnam. We can easily come across images and information about the environment being polluted right in the media. This makes us think ... The planning of urban areas is not associated with the problem of waste and wastewater treatment, so environmental pollution in big cities, industrial parks and urban areas is at an alarming level. Out of 183 industrial parks in the country, over 60% of industrial parks do not have a centralized wastewater treatment system. In urban areas, only about 60% - 70% of solid waste is collected, drainage infrastructure and wastewater treatment, waste should not meet the requirements of environmental protection ... Most of the water untreated waste is discharged directly into rivers and lakes and is forecasted to be 510,000m3 / day by 2010. The heartbreaking example of the discharge of wastewater, no one would not know, is the case of the Thi Vai river contaminated by chemicals discharged from the factory of the Vê Dan MSG for 14 consecutive years. The river is seriously polluted affecting the lives of many people around. Or the pollution of Hoan Kiem Lake, a symbol of national culture. So what is the cause of the above?học tốt
