SH+E Group was awarded main contractor for the design, realization and long term maintenance of the Project. SH+E is cooperating closely with the Dutch consultancy firm Grontmij (design), Hegeman (realization works) and the Canadian firm Ostara Nutrient Recovery Technologies (nutrient recovery and fertilizer production).

Energy surplus to national power grid

污水廠中產(chǎn)生的電能滿足自給外多余的能量被輸送到國家電網(wǎng)！
All sludge’s produced by the treatment of wastewater of the communities Amersfoort, Soest, Nijkerk and Woudenberg will be centrally digested at WWTP Amersfoort . By doing this, more biogas will be produced for conversion into 'green electricity'.

The process of digestion will be enhanced with Thermal Pressure Hydrolysis (TPH), in order to increase the biogas production by 'cracking' the sludge structures under high temperature and pressure.

（點評：污泥壓力熱水解技術(shù)被用于強化污泥消化的預(yù)處理，可大幅增加厭氧過程的沼氣產(chǎn)量，北歐多座污水廠采用。）

The green energy produced will be sufficient to treat all the wastewater from the City of Amersfoort (150.000 p.e.) on a 100% energy-autonomous basis.

（點評：產(chǎn)生的電能可以滿足150000人口當量的Amersfoort的電能需求）

Furthermore, a surplus of approx. 2,000,000 kWh, which will not be used by the treatment processes, will be supplied to the national power grid. This is substantially sufficient to provide 600 households with green electricity during the year.

（點評：污水廠產(chǎn)生的多余電能約 2,000,000 kWh被輸送到國家電網(wǎng)，不但實現(xiàn)了污水廠能耗的自給，還持續(xù)供給外部電網(wǎng)。）

Nutrients become certified fertilizer

污水中的N、P被提取出來作為肥料

The digestion and sludge treatment processes will also produce waste streams that are rich of nutrients like phosphorus and nitrogen. The project will employ nutrient recovery technology from Ostara recover and transform these valuable nutrients into an environmentally responsible fertilizer called Crystal Green.

（點評：污水廠污泥處理工序產(chǎn)生的大量的高濃度的富氮、富磷液體（rejectwater)中的N、P利用Ostara技術(shù)被提取出來的肥料被稱為“水晶綠”，可以農(nóng)用。一個污水廠同時能變成產(chǎn)能廠，同時抽取了污水里的營養(yǎng)物質(zhì)回歸農(nóng)田，至今這在國內(nèi)沒有一個污水廠可以做到。我們的污水廠甚至連厭氧消化系統(tǒng)都不能穩(wěn)定運行，原因在哪里/)

The facility will produce approximately 900 tonnes of high quality fertilizer annually. With applications in the agriculture, turf and horticulture sectors, Crystal Green is European Certified in the category with the highest quality fertilizers.

這個廠每年可以提取大概900噸的高質(zhì)量肥料!

Maximise recovery from waste water
As main contractor, the SH+E Group will supply and install all processes for treatment of the sludges, thermal pressure hydrolysis (Lysotherm) and the generation of heat and electricity out of the produced biogas.

The project is expected to be completed in 2015, which is an important milestone for the Dutch waterboard in the realization of their ambition to both treat waste water energy autonomously and at the same time maximise recovery of valuable nutrients from processed waste streams.
