Greenhouse gases
แปลว่า(Environmental Engineering) Gases which trap solar radiation. Of the solar energy entering the earth's atmosphere a portion is reflected back and a portion penetrates onto the earth's surface. The portion reflected back from the earth's surface is at a different wavelength that when it entered. Carbon dioxide and other gases, which pass solar radiation, absorb this reflected radiation, increasing the earth's temperature. This is much like a greenhouse, hence the name.
Trophic level
แปลว่า(Environmental Engineering) A level in the food chain. The first trophic level consists of the primary producers, autotrophs. The second trophic level is vegetarians which consume autotrophic organisms.
Nitrogen fixation
แปลว่า(Environmental Engineering) The conversion of atmospheric (or dissolved) nitrogen gas into nitrate by microorganisms.
Ecology
แปลว่า(Environmental Engineering) The study of living organisms and their environment or habitat.
Biochemical oxygen demand (BOD)
แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any organic matter present in a water during a specified period of time, usually 5 days. It is an indirect measure of the amount of organic matter present in a water.
Biogeochemical cycle
แปลว่า(Environmental Engineering) The cycle of elements through the biotic and abiotic environment.
Attached growth reactor
แปลว่า(Environmental Engineering) A reactor in which the microorganisms are attached to engineered surfaces within the reactor. Examples of attached growth reactors are the trickling filter and the rotating biological contactor. See suspended growth reactor.
Shock load
แปลว่า(Environmental Engineering) Influent wastewater entering the plant which has an unusually high organic content and/or high flow rate.
Volatile solids
แปลว่า(Environmental Engineering) (VS) is the amount of matter which volatilizes (or burns) when a water sample is heated to 550EC.Volatile suspended solids
