Trinidad and Tobago wastewater treatment plant begins operation

Updated: 2019-07-19

The Malabar Wastewater Treatment Plant in Trinidad and Tobago, which was built by POWERCHINA, was officially put into operation on July 12.

After its operation, it will reduce the pollutants discharged into rivers, as well as improve the water quality of rivers and groundwater, effectively solving the problem of insufficient wastewater treatment capacity in the country.

The government of Trinidad and Tobago said that the project's commissioning and operation has played a very positive role in impoving the country's ecological environment. They expressed great appreciation that POWERCHINA completed the project on schedule and controlled the project cost within the budget.

It is expected that China and Trinidad and Tobago will have deeper and further cooperation opportunities to continuously enhance the relations between the two countries, the government added.

Located at the Malabar catchment area, the Malabar Wastewater Treatment Plant covers an area of 27 square kilometers, including the plant area, three lift pumping stations, and about 10 kilometers of pipelines. It is capable of handling domestic wastewater of about 110,000 households.

The project optimizes its design and introduces the A/O process, as well as uses environmental protection and energy-saving equipment, solving the problem of sludge treatment at the initial stage of commissioning.

The end-treated sewage can be reused as a water source, which reduces the dependence on external water sources during the whole sewage treatment process.

With the continuous operation of the plant, it can also produce a large amount of crop fertilizer, which has strong environmental and economic benefits.

公司承建的特立尼达和多巴哥污水处理厂投运

当地时间7月12日,由中国电建承建的特立尼达和多巴哥马拉巴尔污水处理厂正式投产运行。投产后,排入河的污染物显着减少,河道及地下水的水质得到了改善,将有效解决该国当前污水处理能力不足的问题。

特多政府方面表示,该项目的投产运行对提升特多生态环境具有非常积极的作用,同时对中国水电能出色的按期完成项目,并将工程费用控制在预算范围内表示了极大的肯定,对参与此项目的所有团队及员工表示感谢,并由衷希望中国-特多能够有更深、更远的合作机会,不断增进两国之间的友谊。

马拉巴尔污水处理厂位于马拉巴尔集水区,覆盖27平方公里区域,包括厂区、3个提升泵站、约10公里管线,能够处理约11万户以上居民的生活污水。

该工程优化设计引入A/O工艺,选择环保节能设备,成功解决了调试初期污泥处理问题,同时末端处理后的污水可当作水源再利用,减少了整个污水处理过程中对外部水源的依赖,降低了运营成本。随着污水厂的不断运营,还可以产出大量的农作物肥料,具有较高的环境效益和经济效益,一举而多得。
