丹多勒污水治理厂

丹多勒污水治理厂距离肯尼亚内罗毕30公里,是非洲最大的废水稳定池,每天可处理80,000m³的废水(占内罗毕废水总量的80%)。

从该污水处理厂流出的污水被排入奈洛比河进行再利用,目前由于超负荷,还没有达到指定要求。为了提高处理厂效能以及减少温室气体的排放,肯尼亚挚高水服务委员会提出建立能源发电设施,使用沼气(由稳定池产生)进行发电。

我们受聘于肯尼亚挚高水服务委员会就在厂区新建能源发电设施完善一份可行性研究以及初步设计和经济分析。

我们的工作范围包括:

  • 就当前的有机负荷做出一份研究,以预估处理过程中排放的废气量
  • 制定关于废气收集办法的提议,以增加处理能力以及提高处理效率
  • 提出废气最经济有效的利用方案,同时确定其他关于污水利用潜力的办法,以处理污水及副产品。

该项目通过建造利用稳定池产生的沼气进行能源发电的设施提高该厂的效率,减少温室气体的排放。

Dandora Sewage Treatment Plant

Located 30 km from Nairobi in Kenya, Dandora Estate Sewerage Treatment Plant features the largest wastewater stabilisation pond in Africa, treating 80,000 m³ of sewerage per day (80% of Nairobi’s wastewater).

The effluent from the treatment plant, which is discharged into Nairobi River for reuse, currently does not meet required quality standards due to overloading. In order to improve plant performance and reduce greenhouse gas emissions, the Kenya Athi Water Services Board (AWSB) proposed the construction of a new Energy Generating Facility that would utilise methane gas (produced by the stabilisation ponds) to generate power.

We were engaged by AWSB to complete a feasibility study, preliminary design and economic analysis of a new Energy Generating Facility at the Plant.

Scope of work included:

  • A study of current organic loadings to estimate the amount of gas released from the treatment process
  • Proposal of a gas collection method to help increase treatment capacity and improve treatment efficiency
  • Propose the best use of the gas, taking economic benefits into account Identify other potential uses of waste water, treated effluent and byproducts

This project will improve the plant’s performance and reduce greenhouse gas emissions by constructing an energy generating facility that utilises methane gas produced by the stabilisation ponds.
