What Is a Phase 1 Environmental Assessment?

Environmental status assessment is generally based on the environmental monitoring data of the past two or three years to evaluate the environmental quality of a certain area. Generally based on environmental quality standards or environmental background values promulgated by the state. The evaluation scope can be an administrative area, a natural area or a functional area.

Environmental Status Assessment

The scope of the environmental status assessment can be divided according to environmental functions, such as a city, an industrial area, and a tourist area; it can be divided according to natural conditions, such as a watershed and a plain; it can be divided according to administrative areas, such as a County, a district. Evaluation of the environmental quality of a region

The evaluation content mainly includes:

The first stage is the preparation stage. The main work is to study relevant documents, conduct preliminary engineering analysis and environmental status investigation, screen key evaluation items, determine the work level of each individual environmental impact assessment, and prepare an evaluation outline;

The second phase is the formal work phase, and its main work is detailed engineering analysis and environmental status investigation.

And carry out environmental impact prediction and assessment of environmental impacts;

The third stage is the preparation of the report. Its main work is to summarize and analyze the various data obtained in the second stage.

Data, give conclusions, complete

Environmental impact assessment is referred to as environmental assessment, environmental assessment, and environmental assessment. The English abbreviation EIA stands for Environmental Impact Assessment.

Environmental impact assessment refers to the analysis, prediction and assessment of the possible environmental impacts after the implementation of planning and construction projects, the proposed countermeasures and measures to prevent or mitigate adverse environmental impacts, and methods and systems for follow-up monitoring. In popular terms, it is to analyze the possible impact on the environment after the project is completed and put into production, and propose pollution prevention countermeasures and measures.

From the initial diffusion and dilution, water washing, to traditional adsorption, incineration, and chemical absorption, to emerging deodorization technologies such as biological deodorization, photocatalytic oxidation, ozone oxidation, and plasma decomposition, the management of malodor is nothing but physical , Chemical, biological means, or their combined processes, to reduce or eliminate them through processes such as dilution neutralization, absorption transformation or biodegradation.

The conventional control technologies for malodor (as shown in Table 1) have their own advantages and limitations [3-11]. The physical method is only suitable for low-concentration, small-scale malodor, and the cost is high; the chemical method is not durable, and the investment and operation cost of the deodorization facility are high; although the biological method is low in cost and good in effect, the screening and cultivation of the strains are more Difficult, slower.

Therefore, according to the characteristics, strength, and deodorization requirements of landfill odors, appropriate treatment technologies should be selected, or a combined process should be adopted to minimize odors and reduce pollution.
