井泵 meaning in English

well pump

The long - term solution might instead lie in deep tubewells , which extract water from aquifers 200 meters or farther underground
长远的解决之道可能是深管式井泵，从地下200公尺或更深的含水层抽水。
Geologists agree that the risk of arsenic in deep aquifers is low , but before a few million such tubewells are dug , they need to be absolutely sure
地质学家认同较深那一层含砷的风险低，不过，在开凿几百万个深管式井泵之前，这件事必须绝对确认。
Today around 30 percent of bangladesh ' s tubewells are known to yield more than 50 micrograms of arsenic per liter of water , with 5 to 10 percent providing more than six times this amount
目前在孟加拉，已知大约30 %的管式井泵中，每公升水含有超过50微克的砷； 5 ~ 10 %管式井泵的砷含量更是这数字的六倍以上。
Controversy continues to rage , however : chakraborti asserts that some tubewells he measured to be arsenic - free a decade ago are now poisoned , suggesting that complex geochemical processes are even now under way
不过争论仍在持续，加卡波狄声称，某些管式井泵在他10年前测试时是无砷的，现在却有毒，暗示著复杂的地球化学过程直至今日还在继续。
