Chemical oxygen demand (COD)

แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any organic matter in the water using harsh chemical conditions.

Basic Oxygen Furnace (BOF)

แปลว่า(english) "WHAT A pear-shaped furnace, lined with refractory bricks, that refines molten iron from the blast furnace and scrap into steel. Up to 30% of the charge into the BOF can be scrap, with hot metal accounting for the rest. WHY BOFs, which can refine a heat (batch) of steel in less than 45 minutes, replaced open-hearth furnaces in the 1950s; the latter required five to six hours to process the metal. The BOF's rapid operation, lower cost and ease of control give it a distinct advantage over previous methods. HOW Scrap is dumped into the furnace vessel, followed by the hot metal from the blast furnace. A lance is lowered from above, through which blows a high-pressure stream of oxygen to cause chemical reactions that separate impurities as fumes or slag. Once refined, the liquid steel and slag are poured into separate containers. "

Basic Oxygen Process 2

แปลว่า(english) A steel making process wherein oxygen of the highest purity is blown onto the surface of a bath of molten iron contained in a basic lined and ladle shaped vessel. The melting cycle duration is extremely short with quality comparable to Open Hearth Steel.

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.

Aerobic process

แปลว่า(Environmental Engineering) A process which requires molecular oxygen.

เต็นท์

หมายถึงน. ที่พักหรือที่อาศัย ย้ายไปได้ โดยมากทำด้วยผ้าใบขึงกับเสาหรือหลัก. (อ. tent).

Anoxic process

แปลว่า(Environmental Engineering) A process which occurs only at very low levels of molecular oxygen or in the absence of molecular oxygen.

Anaerobes

แปลว่า(Environmental Engineering) A group of organisms that do not require molecular oxygen. These organisms, as well as all known life forms, require oxygen. These organisms obtain their oxygen from inorganic ions such as nitrate or sulfate or from protein.

Reaeration

แปลว่า(Environmental Engineering) The dissolving of molecular oxygen from the atmosphere into the water.

Respiration

แปลว่า(Environmental Engineering) Energy production in which oxygen is the terminal electron acceptor, i.e. oxidation to produce energy where oxygen is the oxidizing agent. See fermentation.
