Abstract

Anthropogenic and industrial wastewater (IWW) could be an additional future source of water to support the needs of the people of the State of Qatar. New lagoons have been built using modern technologies to optimize water use and waste recycling, as well as increasing the green spaces around the country. To achieve successful development of these new lagoons, lessons should be learned from the old ponds by examining their biodiversity, ecology, and the roles played by aquatic plants and algae to remediate wastewaters at these ponds. The perspectives of using IWW (from oil and gas activities), that is currently pumped deep into the ground are presented. Instead of causing great damage to groundwater, IWW can be stored in artificial ponds prepared for ridding it of all impurities and pollutants of various types, organic and inorganic, thereby making it serviceable for various human uses. Phycoremediation, bioremediation, and phytoremediation methods adopted by algae, bacteria and aquatic native plants are discussed, and special attention should be paid to those that proved successful in removing heavy metals and degrading organic compounds. At least three native plants namely: Amaranthus viridis, Phragmites australis, and Typha domingensis should be paid special attention, since these plants are efficient in remediation of arsenic and mercury; elements found abundantly in wastewater of gas activities. Some promising modern and innovative experiences and biotechnologies to develop efficient transgenic plants and microorganisms in removing and degrading pollutants are discussed, as an important strategy to keep the ecosystem clean and safe.

Novelty statement

Industrial wastewater (IWW) could be an alternative source of water at the Arabian Gulf region. Currently, IWW is pumped deep into the ground causing a great damage to groundwater; little information about this issue has been reported. Such IWW can be stored in artificial ponds designed for ridding them of all impurities of various types; various remediation methods can be used. Modern biotechnology to develop transgenic plants and microorganisms to enhance these remediation methods can be adopted.

摘要

人为和工业废水（IWW）可能会成为将来增加的水源，以满足卡塔尔国人民的需求。利用现代技术建造了新的泻湖，以优化用水和废物回收利用，并增加全国的绿地面积。为了成功开发这些新的泻湖，应通过检查旧池塘的生物多样性，生态学以及水生植物和藻类在这些池塘中治理废水的作用来吸取教训。介绍了使用IWW（来自石油和天然气活动）的观点，该观点目前已被泵入地下。IWW不会对地下水造成严重破坏，而可以将其存储在人工池塘中，以清除所有类型的有机和无机杂质和污染物。从而使其可用于各种人类用途。讨论了藻类，细菌和水生原生植物采用的植物修复，生物修复和植物修复方法，应特别注意那些已成功去除重金属和降解有机化合物的方法。至少三种本地植物：应特别注意菜，芦苇和香蒲，因为这些植物对砷和汞的修复效率很高。在天然气活动废水中大量发现的元素。讨论了开发有效的转基因植物和微生物以去除和降解污染物的一些有前途的现代和创新经验和生物技术，这是保持生态系统清洁和安全的重要策略。

新颖性声明

工业废水（IWW）可能是阿拉伯海湾地区的替代水源。目前，IWW已被泵入地下深层，对地下水造成了严重破坏；关于此问题的报道很少。这种IWW可以储存在人工池塘中，以清除各种杂质。可以使用各种补救方法。可以采用开发转基因植物和微生物以增强这些修复方法的现代生物技术。
