The total amount in the environmental impact assessment report is calculated

SO2, NOX, soot, list of individual pollution sources, generally only count organized emissions, concentration multiplied by air volume, and then multiplied by total production time, first calculate the total amount of individual pollution sources, and then calculate, the total amount of all pollution sources. The total amount of COD and ammonia nitrogen in the wastewater, the number of each discharge port is counted, the total amount of a single sewage outlet is calculated first, the concentration is multiplied by the annual sewage discharge, and then the total amount of each pollution source is summed up.

In the total calculation, SO2, NOX, and soot are calculated as follows (calculated according to different fuels):

For example, if natural gas is burned, the natural gas emission parameters (which can be found in the "Environmental Protection Practical Data Manual") are SO2 is 10,000 m3, NOx is 10,000 m3, and soot is 10,000 m3; From this, the amount of natural gas used (volume: m3) can be calculated to obtain SO2, NOx, and soot emissions.

If it is coal-burned, SO2 is the amount of coal burned * sulfur content (percentage) * 2 (i.e., one part of sulfur (32) produces two parts of sulfur dioxide (64)) * this coefficient is an empirical formula), and soot is the amount of coal burned * ash content (percentage) * that is, about 70% of the ash in the coal generates soot and 30% produces cinder; Calculated accordingly.

If it is a fuel oil, SO2 is the amount of fuel * sulfur content (percentage) * 2 (that is, one part of sulfur (32) can be obtained by generating 2 parts of sulfur dioxide (64), and soot is the amount of fuel * the dust content (percentage) in the oil; Calculated accordingly.

Calculation of COD and total ammonia nitrogen in wastewater:

First, determine the average concentration of COD and ammonia nitrogen in wastewater, then the total amount of COD = wastewater volume * COD concentration, and the total amount of ammonia nitrogen = wastewater volume * ammonia nitrogen concentration can be obtained. For example, if the annual discharge of wastewater is 10,000 tons and the COD concentration is 500mg L, then the total amount of COD = 10,000 tons * 500mg L (i.e. G t) = 5,000,000 g = 5 tons. And so on.

The environmental impact report refers to the environmental impact report form in simple form. A written representation of the process and content of the environmental impact assessment. The information and results obtained from a series of activities completed and submitted by the environmental impact assessment unit will be carried out from the purpose of protecting the environment, and the feasibility study of the construction project will be carried out through comprehensive evaluation, demonstration and selection of the best plan, and the opinions of the land brothers will be listened to, so as to achieve a reasonable layout and the least possibility of environmental pollution and destruction.

Summary. Hello dear, how to calculate the total amount of exhaust gas in the total amount control index of the EIA, for you to answer: 1

The conversion process is to convert the unit of exhaust gas from tonne-years to cubic metre-years. 2.It is enough to divide the weight of the exhaust gas by its density.

3.However, the density of different varieties of exhaust gas is not the same, so it is necessary to sample the exhaust gas and measure its density, and then it can be converted into cubic meter years.

Hello, how to calculate the total amount of exhaust gas in the total vertical slip control index of the EIA, and answer for you: 1The conversion process is to convert the unit of exhaust gas from tonne-years to cubic metre-years.

2.It is enough to divide the weight of the exhaust gas by its density. 3.

However, the density of different varieties of waste gas is not the same, so it is necessary to sample the exhaust gas discharged first, measure its density, and then convert it into cubic meters of years.

Using the measured method, the formula for rock mining failure is as follows: actual exhaust gas emissions = emission rate x production days x daily working time x 10-3 or actual exhaust gas emissions coarse tremor = emission concentration x benchmark flow x production days x daily working time x 10-9. Here's an example:

The particulate matter emission rate in the third quarter was 21mg m3, the benchmark flow rate was 15988m3 h, and the average daily work was 8 hours, with a total of 84 days from July to September. The actual emission of particulate matter is calculated according to the emission rate = 5 decimal places are retained, and the actual emissions of particulate matter = 21x15988x8x84x10-9 = 5 decimal places are retained.

How to calculate the amount of exhaust gas in the EIA and the calculation formula.

The formula is adopted: the actual emission of exhaust gas slippage = emission rate x production days x daily working time liter Hu x10-3 or noisy exhaust gas actual emission = emission concentration x benchmark flow x production days x daily working time x 10-9.

Exhaust gas volume Exhaust gas emissions?

For those exhaust gases that are directly emitted without exhaust gas environmental protection equipment, the amount of exhaust gas generated is the same as the amount of emissions.

What about the exhaust gas emitted by environmental protection equipment through the exhaust cylinder?

It's a waste amount.

Is it to calculate the actual emissions of all pollutants and add them up and then convert them into units?

Yes, you can follow this formula: actual emissions of exhaust gas = emission rate x number of production days x daily working time x 10-3 or actual emissions of exhaust gas = emission town index annual concentration x benchmark flow royal opening amount x production days x daily working hours x 10-9.

You might as well take a look at the Environmental Impact Assessment Method for yourself.

You'll be clear.

According to Article 7 of the Regulations on the Administration of Environmental Protection of Construction Projects:

According to the degree of impact of construction projects on the environment, the State implements classified management of environmental protection of construction projects in accordance with the following provisions.

1) If the construction project may have a major impact on the environment, an environmental impact report shall be prepared to conduct a comprehensive and detailed assessment of the pollution caused by the construction project and the impact on the environment;

2) If the construction project may have a slight impact on the environment, an environmental impact report form shall be prepared to analyze or make a special assessment of the pollution and environmental impact of the construction project;

3) If the environmental impact of the construction project is very small and there is no need for environmental impact assessment, the environmental impact registration form shall be filled.

The directory of classified management of environmental protection of construction projects shall be formulated and published by the competent administrative department of environmental protection.

Note: The above two sub-items are about the provisions of the classified management of construction projects, but the former is a law and the latter is a regulation. The two are slightly different, the former is called "environmental impact assessment implements classified management"; The latter is "classified management of environmental protection".

Example] A construction project has little impact on the environment B The construction project may have a slight impact on the environment.

c. The construction project may have a significant impact on the environment, and the d. The construction project cannot have a significant impact on the environment.
