ตัวกรองผลการค้นหา
Biogeochemical cycle
แปลว่า(Environmental Engineering) The cycle of elements through the biotic and abiotic environment.
Biofilm
แปลว่า(Environmental Engineering) A film of microorganisms attached to a surface, such as that on a trickling filter, rotating biological contactor, or rocks in natural streams.
saccharobiose
แปลว่า(เคมี) อ้อย ; น้ำตาลที่ทำจากอ้อย
Biosynthesis
แปลว่า(Environmental Engineering) Catabolism, the production of new cellular materials from other organic or inorganic chemicals.
Ultimate biochemical oxygen demand (BODu)
แปลว่า(Environmental Engineering) The total amount of oxygen required to oxidize any organic matter present in a water, i.e. after an extended period, such as 20 or 30 days.
Carbonaceous biochemical oxygen demand (CBOD)
แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any carbon containing matter present in a water.
Trickling filter
แปลว่า(Environmental Engineering) An attached growth biological process in which the microbial film is attached to non-moving rock or plastic media.
Anabolism
แปลว่า(Environmental Engineering) Biosynthesis, the production of new cellular materials from other organic or inorganic chemicals.
Nitrification
แปลว่า(Environmental Engineering) The biological oxidation of ammonia and ammonium sequentially to nitrite and then nitrate. It occurs naturally in surface waters, and can be engineered in wastewater treatment systems. The purpose of nitrification in wastewater treatment systems is a reduction in the oxygen demand resulting from the ammonia.
gabion
แปลว่าเกเบียน, กล่องหินลวดตาข่าย
Autotrophic
แปลว่า(Environmental Engineering) Organisms which utilize inorganic carbon for synthesis of protoplasm. Ecologists narrow the definition further by requiring that autotrophs obtain their energy from the sun. In microbiologist parlance, this would be a photoautotroph. See photoautotrophic and chemoautotrophic.
Denitrification
แปลว่า(Environmental Engineering) The anoxic biological conversion of nitrate to nitrogen gas. It occurs naturally in surface waters low in oxygen, and it can be engineered in wastewater treatment systems.
