What should I prepare for the 2008 Pollution Source Survey?

Consider pollution sources, the environment, and the health of the population as a system. Attention should be paid not only to the emission and characteristics of pollutants, but also to the pollution pathways and effects on human health, as well as environmental and economic issues. Ensure the reliability and accuracy of the information obtained from the survey.

In order for the resulting material to be comparable, it is necessary to collect information and data in accordance with uniform requirements, as well as to harmonize methods of monitoring, estimation and data processing.

The task of a pollution source investigation varies depending on the purpose. If the purpose is to formulate a comprehensive prevention and control plan or environmental quality management plan for a certain area, the task of the survey is to have a comprehensive understanding of the pollution sources in the area, so as to determine the main pollution sources and main pollutants; If it is to control a certain type of pollution source in an area, such as electroplating wastewater pollution source, the task of investigation is to find out the distribution of electroplating workshops in the area, the production status of each workshop, the sewage discharge situation and its impact on the environment; If the purpose is to provide information for the daily management of pollution sources, the task of the investigation is to identify the situation of various pollution sources and their impact on environmental quality. The various surveys described above can be combined.

The first step of pollution source investigation is to conduct a general survey to find out the general situation of pollution sources and pollutants in the area, and to classify and sort out the investigation materials; The second step is to determine the object of further investigation according to the characteristics of environmental problems in the region (such as mainly air pollution or water pollution) and conduct in-depth investigation; Finally, the investigation data is collated, the investigation report is written and the pollution source file is established. The main contents of the census are the name and location of the pollution source, the name of the pollutant, the amount discharged, the intensity of the discharge, the mode of discharge, the direction of the discharge (to the atmosphere, water, etc.) and the discharge law (regular centralized discharge, continuous and uniform discharge, etc.). The content of further investigation varies depending on the source of the contamination.

For example, the investigation items of industrial pollution sources include: main product types, output, total output value, profits, number of employees, types of raw materials, total consumption and quota of raw materials (including fuel, raw materials and water, etc.), production process, main equipment and devices, sewage discharge, treatment status and plan, etc. The investigation items of domestic pollution sources are:

Population, water and sewerage conditions, fuel composition and consumption, sewage discharge per person per day, etc. In addition to summarizing the general situation, suggestions on treatment methods should be put forward in the pollution source investigation report. The pollution source file is mainly to record the basic situation of each pollution source in statistics and schemas.

According to the requirements of pollution control and improvement of environmental quality, the causes of pollution in a certain area (such as a city or a river basin) are investigated by sheds, various pollution source files are established, evaluation standards are selected on the basis of comprehensive analysis, the degree of harm to the environment and its potential danger of each pollution source are estimated and compared, and the key control objects (main pollution sources and main pollution traces in the area) and control methods are determined.
