ตัวกรองผลการค้นหา
Dump
แปลว่า(Environmental Engineering) An illegal and uncontrolled area where wastes have been placed on or in the ground. See Landfill.
Autotrophs
แปลว่า(Environmental Engineering) A group of organisms capable of obtaining carbon for synthesis from inorganic carbon sources such as carbon dioxide and its dissolved species (the carbonates). This group includes plants and algae.
Chlorofluorocarbons
แปลว่า(Environmental Engineering) Synthetic organic compounds used for refrigerants, aerosol propellants (prohibited in the U.S.), and blowing agents in plastic foams. CFCs migrate to the upper atmosphere destroying ozone and increasing global warming. Typical atmospheric residence times are 50 to 200 years.
Dissolved oxygen (DO)
แปลว่า(Environmental Engineering) The amount of molecular oxygen dissolved in water.
Photochemical pollutants
แปลว่า(Environmental Engineering) Chemicals which react photochemically (in the presence of sunlight) to destroy ozone in the stratosphere.
Fluidization
แปลว่า(Environmental Engineering) The suspension of particles by sufficient upward velocity of the fluid. During fluidization the gravity force is overcome by a combination of buoyancy and fluid friction.
CFCs
แปลว่า(Environmental Engineering) Chlorofluorocarbons, chemicals which result in a depletion of the ozone layer in the upper atmosphere.
Closure
แปลว่า(Environmental Engineering) The act of preparing a landfill for long term inactivity, including placement of a cover over the landfill to prevent infiltration of surface water.
Anaerobic process
แปลว่า(Environmental Engineering) A process which only occurs in the absence of molecular oxygen.
Burning 2
แปลว่า(english) Heating a metal beyond the temperature limits allowable for the desired heat treatment, or beyond the point where serious oxidation or other detrimental action begins.
Environmental Management Plan
แปลว่าแผนการจัดการสิ่งแวดล้อม
Source reduction
แปลว่า(Environmental Engineering) The elimination or reduction of the waste at the source by modification of the actual process which produces the waste.
