A superlative policy for alleviating shortage of fresh water ── on direct utilization of seawater in Qingdao

非传统水资源主要包括污水回用、海水直接利用与海水淡化、雨水资源化、微咸水开发利用等。

The non-traditional water resources mainly includes water reuse , seawater desalination , rainwater use , brackish water utilization etc. .

目前，海水直接利用后排放的污水及其他工业中排放的含盐污水的处理成为人们普遍关注的问题。

At present , it is concerned how to treat sewage produced by sea water direct utilization and saline sewage by the other industries .

渤海海域海水直接利用量占该海域平均年降水量的8.82%，其中辽东湾的海水利用量占该湾平均年降水量的3.09%，渤海湾为15.86%，莱州湾为17.38%；

The amount of the sea water which was directly utilized from Liaodong Bay is 3.09 % of the average annual precipitation in this bay , which is 15.86 % in Bohai Bay , 17.38 % in Laizhou Bay and 8.82 % in the whole Bohai Sea .

含盐废水包括海水直接利用后排放出的废水和一些工业废水，如化工废水、食品废水、制药废水等。因为含盐量高，废水生化处理具有一定的难度。

Saline wastewater contains wastewater discharged from direct using and some Industrial effluents , such as chemical industrial wastewater , food wastewater and pharmaceutical wastewater , etc. Because of the high salt content , the salinity wastewater is not easy to be treated with anaerobic biological technology now .

国家鼓励和支持沿海地区发展海水淡化和海水直接利用。

The state shall encourage and support seawater desalination and direct seawater utilization in the coastal area .

海水淡化和海水直接利用将是解决沿海城市水紧缺的战略选择和根本措施。

Seawater desalination and direct use is a strategic option and fundamental measure for solving the freshwater shortage in coastal cities .

例如，根据青岛市的临海有利地势，采用海水淡化及海水直接利用的方法，减少淡水使用量。

For example , under favorable terrain coastal city of Qingdao , the use of seawater desalination and direct use of methods to reduce water usage .

大生活用海水技术是海水直接利用技术的主要组成部分，可代替沿海地区35%左右的生活用水。

Domestic seawater technology is one of the mostly parts of seawater directly utilization technology . It can save about 35 % of domestic water in littoral .

水循环冷却技术，是海水资源利用领域一项新技术，属于海水直接利用技术的范畴。

As one of new technique in the field of seawater resource utilization , seawater circulating cooling technology is one way to utilize seawater directly .

目前，海水资源开发形成了盐业、盐化工业，以及海水直接利用和海水淡化等新兴产业。

Currently , some of China 's new industries are associated with this aspect of marine resources development and exploitation : salt , salt chemicals , direct seawater utilization and seawater desalination .
