Waste minimization

แปลว่า(Environmental Engineering) The elimination or reduction of a waste prior to its generation. This is accomplished by process changes rather than waste treatment methods.

Reactive waste

แปลว่า(Environmental Engineering) A waste which; 1) reacts violently with water, 2) forms potentially explosive mixtures with water, 3) is normally unstable, 4) contains cyanide or sulfide in sufficient quantity to evolve toxic fumes at high or low pH, 5) is capable of exploding if heated under pressure, or 6) is an explosive compound listed in Department of Transportation (DoT) regulations. One of EPA's four hazardous waste properties.

Corrosive waste

แปลว่า(Environmental Engineering) A waste that is outside the pH range of 2 to 12.5 or a waste that corrodes steel at a rate greater than 6.35 mm (0.25 in) per year. One of EPA's four hazardous waste properties.

In situ treatment

แปลว่า(Environmental Engineering) Treatment of a waste in place, as opposed to pumping or digging the waste up and then treating it.

Decomposers

แปลว่า(Environmental Engineering) Organisms which utilize energy from wastes or dead organisms. Decomposers complete the cycle by returning nutrients to the soil or water and carbon dioxide to the air or water.

Advanced wastewater treatment

แปลว่า(Environmental Engineering) The removal of any dissolved or suspended contaminants beyond secondary treatment, often this is the removal of the nutrients nitrogen and/or phosphorus.

waste drain

แปลว่าท่อระบายของเสีย

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.

Publicly owned treatment works (POTW)

แปลว่า(Environmental Engineering) A municipal or domestic wastewater treatment facility.

waste

แปลว่าเศษไม้ [ป่าไม้] ; ของเสีย [โยธา, สิ่งแวดล้อมน้ำ]

cotton waste

แปลว่าด้ายดิบที่รวมเส้นเป็นกลุ่มใช้สำหรับเช็ดถูทำความสะอาดเครื่องยนต์ หรือใช้พันอัดเกลียวข้อต่อท่อโลหะ

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.
