The answer for your question is “B. Constituent”
Answer:
<em>Geotextile </em>would help prevent the creation of leachate. U<em>sing a single-liner system rather than a double-liner system </em>would help prevent the creation of leachate.
Explanation:
Landfill liners must have several layers, including a one of soil, then a geotextile (a synthetic permeable membrane) layer that lets water through but filters out any small pieces of trash, a leachate (water) collection system, a plastic liner layer in order to prevent leachate from reaching the groundwater, and to prevent leachate from polluting the underlining groundwater.
The generation of leachate is caused principally by precipitation percolating through waste deposited in a landfill. Once in contact with decomposing solid waste, the percolating water becomes contaminated, and if it then flows out of the waste material it is termed leachate.
Therefore, there are many methods of leachate treatment such as: Aerobic Biological Treatment such as aerated lagoons and activated sludge. Anaerobic Biological Treatment such as anaerobic lagoons, reactors. Physiochemical treatement such as air stripping, pH adjustment,<em> </em>chemical precipitation, <em>oxidation,</em> and reduction.
Adding oxygen to solid waste prior to landfilling
Answer: It was at it’s rise in the Tang Dynasty (618-907) and it fell in the late 9th century and completely fell apart in A.D 907 when it’s emperor was deposed (removed from office forcefully and suddenly) and the entire country because divided. Hope this helped!
Answer:
cross-sectional
Explanation:
Based on the information provided within the question it can be said that the type of observational study that is being described is a cross-sectional study. This is a type of study in which information is collected at a specific point in time. Since the 1000 adults were selected and interviewed in the same time period then it can be said that this study is a cross-sectional study.
