When selecting Geotextiles for use in domestic waste landfills, factors such as durability, filtration performance, mechanical properties, environmental protection and economy need to be considered. It is recommended to choose high-strength, corrosion-resistant, environmentally friendly polyester fiber or polypropylene fiber materials with moderate thickness and high density. The width should be selected according to the actual situation, and the color should be natural or light. Strengthen maintenance and upkeep, and conduct regular inspections and repairs to ensure the performance and use of geotextiles.

Since domestic waste landfills have high requirements for geotextiles, geotextiles of appropriate specifications need to be selected. Specifically, the following factors need to be considered:

1. Durability: Domestic waste landfills are usually located underground, so geotextiles need to have good durability and corrosion resistance, and can withstand the pressure of garbage and the erosion of corrosive substances for a long time.

2. Filtration performance: Geotextiles need to have good filtration performance, which can effectively block the leakage of liquid and gas in garbage and protect groundwater and soil from pollution.

3. Mechanical properties: Geotextiles need to have certain mechanical properties, such as tensile strength, compressive strength and tear resistance, to be able to withstand the pressure and friction of landfills.

4. Environmental protection: Geotextiles should be made of environmentally friendly materials that can be naturally degraded to avoid secondary pollution to the environment.

5. Economy: On the premise of meeting the above requirements, the selection of geotextiles should also consider cost factors to achieve economic and practical purposes.

Based on the above requirements, it is recommended to choose geotextiles of the following specifications:

1. Material: Choose geotextiles made of high-strength, corrosion-resistant, environmentally friendly polyester fiber or polypropylene fiber materials.

2. Thickness: The thickness should be moderate, generally between 0.5-1.0 mm, to ensure that the geotextile has certain mechanical properties and filtering properties.

3. Density: The density should be higher, generally between 200-300 grams/square meter, to improve the durability and mechanical strength of the geotextile.

4. Width: The width should be selected according to the actual conditions of the landfill, generally between 2-6 meters, to ensure that the geotextile can adapt to the size and shape of the landfill.

5. Color: Natural or light-colored geotextiles should be selected to facilitate observation and discovery of problems in the garbage.

In short, when selecting geotextiles for use in domestic waste landfills, the above factors should be considered comprehensively and geotextiles of appropriate specifications should be selected to ensure the normal operation and service life of the landfill. At the same time, it is also necessary to strengthen the maintenance and maintenance of geotextiles, and conduct regular inspections and repairs to ensure the performance and use effects of geotextiles.
