公馆净水场过滤池 |
| 2. | At that time the water companies of many developed countries also began building rapid filtration plants
当时各先进国家的自来水事业，也纷纷兴建快滤场。 |
| 3. | The rapid filtration plant had a filtration speed of over 100 meters per day , taking only 2 hours to turn raw water into clean water
快滤场每日滤速在100公尺以上，原水变成清水约需2 - 4小时。 |
| 4. | Some $ 4 billion has been committed to finishing a third tunnel to bring water into the city , $ 1 . 6 billion to build a badly needed water - filtration plant and $ 13 billion for the most ambitious school - building upgrade ever
大约40亿美元已确定用于完成第三条地道以引水入城， 16亿美元用于建造一个急需的污水净化工厂，还有130亿美元用于有史以来最大规模的学校修缮计划。 |

规划投资大约40亿美元开凿第三条隧道，将水引入城市，投资160亿美元修建急需的污水处理厂，投资130亿美元用于有史以来最雄心勃勃的学校建设升级计划。 |
| 6. | Through sedimentation , filtration and disinfection , the process of turning raw water into clean water required around 48 hours . though the filtration speed was slow , it provided a stable quality of water until its later replacement by faster working rapid filtration plants
原水经沉淀过滤消毒，最后变成清水，约需48小时，费时虽长，却能供应水质稳定的自来水，日后已被滤速更快的快滤场取代。 |
| 7. | The first category covers maintenance of air - conditioning , electrical and mechanical installations of eight government departments in the transport and security sectors , as well as other services that may be required by all government department and public bodies , e . g . certification of lighting appliances , indoor air quality measurement , overhaul of swimming pool filtration plants and sewage plants
第一类是为8个属运输及保安组别的政府部门的空气调节及机电装置，提供维修服务；此外，该部亦会为所有政府部门及公共机构提供其他所需服务，例如为起重设备签发检验证明、测量室内空气质素、为泳池的过滤装置及污水处理装置进行大修。 |
| 8. | Activities range from the specialised world of stage lighting and engineering systems to leisure equipment , filtration plants , exhibits and amusement rides at museums and parks , energy efficiency audits , indoor air quality measurement and improvement programmes - we have a proven track record in all these systems and services
我们为特殊的舞台灯光及工程系统、康乐设备、滤水设备、博物馆内的展品和公园的机动游戏机、能源效益审计、室内空气质素测量及改善计划等各类系统所提供的专业服务，往绩骄人。 |
