turbidity
含义: The cloudiness or haziness of a liquid caused by suspended particles that scatter light, used as a key indicator of water quality in environmental monitoring.
Turbidity is measured using instruments called turbidimeters or nephelometers, which quantify the scattering of light by particles in suspension. High turbidity in rivers and reservoirs can indicate soil erosion, algal blooms, or pollution discharge, and may render water unsafe for drinking or harmful to aquatic life. Water treatment works monitor turbidity continuously, and UK drinking water regulations set strict limits. The term also appears in wine and brewing to describe clarity. It collocates with 'water quality,' 'suspended sediment,' 'measurement,' 'monitoring,' and 'treatment.'
例句
- Heavy rainfall washed soil into the river, raising turbidity levels and forcing the water treatment plant to increase filtration. 大雨将土壤冲入河中,浊度水平升高,迫使水处理厂加强过滤。Las fuertes lluvias arrastraron tierra al río, elevando los niveles de turbidez y obligando a la planta potabilizadora a aumentar la filtración.大雨により土壌が河川に流入し、濁度が上昇したため、浄水場はろ過を強化せざるを得ませんでした。폭우로 토양이 하천에 유입되어 탁도가 상승했으며, 정수 처리장은 여과를 강화해야 했습니다.
- The Environment Agency recorded a spike in turbidity downstream of the construction site, suggesting inadequate sediment controls. 環境署在建筑工地下游记录到浊度急升,表明沉积物控制措施不足。La Agencia de Medio Ambiente registró un pico de turbidez aguas abajo de la obra, lo que sugería controles de sedimentos inadecuados.環境庁は建設現場の下流で濁度の急上昇を記録し、堆積物管理が不十分であることを示唆しました。환경청은 건설 현장 하류에서 탁도의 급격한 상승을 기록하여 퇴적물 관리가 부적절함을 시사했습니다.
- Drinking water regulations require turbidity to remain below one nephelometric turbidity unit at the point of supply. 饮用水法规要求在供水点浊度保持在一个散射浊度单位以下。La normativa de agua potable exige que la turbidez se mantenga por debajo de una unidad nefelométrica de turbidez en el punto de suministro.飲料水規制では、供給地点での濁度が1ネフェロメトリック濁度単位(NTU)以下であることが求められています。음용수 규정은 공급 지점에서의 탁도가 1 네펠로메트릭 탁도 단위(NTU) 이하로 유지되도록 요구하고 있습니다.
