荷兰Amersfoort污水厂建成为“产能”厂及“肥料”厂
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).
（Ostara 是著名的污水厂侧流营养盐回收技术）
Energy surplus to national power grid
污水厂中产生的电能满足自给外多余的能量被输送到国家电网！
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.
（点评：污泥压力热水解技术被用于强化污泥消化的预处理，可大幅增加厌氧过程的沼气产量，北欧多座污水厂采用。）
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.
（点评：产生的电能可以满足150000人口当量的Amersfoort的电能需求）
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.
（点评：污水厂产生的多余电能约 2,000,000 kWh被输送到国家电网，不但实现了污水厂能耗的自给，还持续供给外部电网。）
Nutrients become certified fertilizer
污水中的N、P被提取出来作为肥料
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.
（点评：污水厂污泥处理工序产生的大量的高浓度的富氮、富磷液体（rejectwater)中的N、P利用Ostara技术被提取出来的肥料被称为“水晶绿”，可以农用。一个污水厂同时能变成产能厂，同时抽取了污水里的营养物质回归农田，至今这在国内没有一个污水厂可以做到。我们的污水厂甚至连厌氧消化系统都不能稳定运行，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.
这个厂每年可以提取大概900吨的高质量肥料!
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.
