ISO发布助力厕所革命的新标准

发布时间: 2018-11-08 10:32:06  

全世界有超过23亿人无法获得基础卫生服务,其中有8.92亿人露天排便。每年有成千上万的儿童因此而患病死亡。新技术正在形成,以便为那些没有污水处理厂的地区提供安全的卫生系统,有望拯救生命和提高许多人的生活福祉。日前ISO发布了备受期待的用以支持这项发展的ISO标准。

对于世界上太多人来说,缺乏清洁卫生和饮用水是一种生活常态。这些人每天都要面对威胁生命的疾病,更别提那些为了上厕所而步入危险境地的妇女和女孩可能面临的暴行。2013年3月,联合国发起一项全球呼吁,即截至2025年,让露天排便成为历史。并为所有人提供“保障全民卫生”的目标,这是联合国2030年日程中17个可持续发展目标(SDG)之一。

为实现这一目标,令人振奋的新技术在诞生,有了无需连接传统下水系统便可安全处理排泄物的独立卫生系统。

通过提供安全和性能要求,不仅可以实现高效生产制造,亦可促进这一产业的整体发展。此类技术的新国际方针定会助力该产业跃至新的水平。

ISO 30500无下水道卫生系统——预制综合处理装置——设计和测试一般安全和性能要求这项标准是生产这些系统的行业和需要它们的国家所翘首以待的。

满足ISO 30500标准要求的系统所排出的物体中没有细菌、病毒及其他有害病原体,故此可以保护人和饮用水等重要资源,使其免于致命疾病爆发的威胁。

制定该项标准的ISO项目委员会主席 Doulaye Koné博士表示,ISO 30500将向制造商、政府、监管部门和最终用户表明,这些无下水道卫生系统设施安全、可靠、品质高。这反过来可以带动针对排水、通电等基础设施不可行的地区开发出更好的厕所。

Doulaye Koné博士说:“ISO 30500标准是30多个国家的专家参与制定的,其中有制定相关技术的产业代表和需求国的政府代表。”

“制造商反映说这一标准是驱动创新、加速产品投入市场的亟需工具,不少政府也将该标准作为制定公共政策的参考。”

塞内加尔卫生设施ONAS的首席执行官Lansana Gagny Sakho表示,塞内加尔计划采用ISO 30500和ISO 24521与饮用水、废水处理相关的活动--家庭废水就地处理管理指南两项标准,并将其作为外包无下水道卫生运营给私营公用事业的一项政策。

“这是家庭废水就地处理服务中的非凡革命,这一最新标准可加速关键私营部门的利益相关者的专业化,”他说:“塞内加尔即将采用ISO 24521和ISO 30500这两项标准,这也能为实现可持续发展目标出点力。”

Attawut Kumkrong是暹罗化工(SCG Chemicals,泰国一家大型石化公司)开放创新和伙伴关系管理的负责人,他说:“ISO 30500可以视作将经过认证的技术从研究结构推向商业化离网型卫生解决方案的工具或指南。此外,通过生产相同质量水准的卫生解决方案,标准化能够营造公平的市场竞争环境,最终会改善人们的生活质量。”

ISO 30500是ISO /PC 305可持续非下水卫生系统项目委员会制定的,美国国家标准化协会(ANSI)与塞内加尔标准化协会(ASN)共同承担了ISO/PC 305秘书处工作。

Toilets that save lives: a new International Standard to help

More than 2.3 billion people across the world lack access to basic sanitation services, including 892 million who defecate in the open. Hundreds of thousands of young children die each year from diseases as a result1). New technology is shaping up to provide safe sanitation systems in places that don’t have sewerage treatment plants, offering the potential to save lives and improve the well-being of many. The highly anticipated ISO standard to support this development has just been published.

For far too many people across the globe, lack of clean sanitation and drinking water is a way of life. Every day, they are exposed to life-threatening disease and illness, not to mention the risk of violence this poses to women and girls who have to wander into unprotected areas to go to the toilet. In March 2013, the United Nations launched a global call to eliminate open defecation by 2025 and made “access to adequate sanitation and hygiene for all” the target of one of the 17 Sustainable Development Goals (SDG) of the UN Agenda 2030.

To this end, exciting new technology is emerging, with the development of stand-alone sanitation systems that safely treat waste without the need to be connected to a traditional sewerage system.

New international guidelines for such technology will help to catapult the industry to a new level by providing safety and performance requirements that will not only enable their effective manufacture, but the development of the sector as a whole.

ISO 30500, Non-sewered sanitation systems – Prefabricated integrated treatment units – General safety and performance requirements for design and testing, is much awaited both by the industry that produces the systems and the countries that need them.

The treated outputs from systems meeting ISO 30500’s requirements will be free of bacteria, viruses and other harmful pathogens, thus protecting people and valuable resources, such as drinking water, from outbreaks of potentially fatal disease.

Dr Doulaye Koné, Chair of the ISO project committee that developed the standard, said ISO 30500 will demonstrate to manufacturers, governments, regulators and end users of the non-sewered facilities that they are safe, reliable and of good quality. This, in turn, will lead to the development of even better toilets in areas where infrastructure such as plumbing and electricity are just not feasible.

“ISO 30500 was developed by a wide range of experts from more than 30 countries, including representatives from the industry that is developing the technologies and those from governments in countries where there is a need,” he said.

“The manufacturers have expressed that the standard is greatly needed as a tool to drive innovation and help accelerate their products to market, while numerous governments are looking at the relevance of the standard as a basis for public policy.”

Lansana Gagny Sakho, CEO of the Senegalese Sanitation Utility ONAS, said Senegal is planning to adopt ISO 30500 and ISO 24521, Activities relating to drinking water and wastewater services – Guidelines for the management of basic on-site domestic wastewater services, as part of a policy to outsource the operation of non-sewered sanitation to private utilities.

“This latest standard will help speed up the professionalization of key private-sector stakeholders involved in this extraordinary revolution in on-site sanitation,” he said. “The impending adoption in Senegal of ISO 24521 and ISO 30500 will also play a part in the realization of the SDGs.”

Attawut Kumkrong, Head of Open Innovation and Partnership Management SCG Chemicals, a large petrochemical company in Thailand, said: “ISO 30500 can be considered a tool or guideline for sourcing and engaging proven technologies from research institutes to develop and manufacture them into commercialized off-grid sanitation solutions. Moreover, standardization allows for fair market competition by producing sanitation solutions with the same quality level, resulting in improved quality of life.”

ISO 30500 was developed by ISO project committee ISO/PC 305, Sustainable non-sewered sanitation systems, whose secretariat is jointly held by ANSI, ISO’s member for the USA, and ASN, ISO’s member for Senegal.
