基于循环经济,探索园区污水处理新思路

Exploring new ideas for wastewater treatment in industrial parks based on recycling economy

为响应国家节能减排和循环经济的理念,本文提出一种新的园区污水处理方式-以污治污:利用企业A废水中的碱性物质与消耗企业B废水中的氢离子,再向废水中投加石灰石去除多余的氢离子,投加液碱去除废水中的铜离子和锌离子。优化后的废水处理方式可减少盐酸、石灰石的使用量,从源头上减少了资源的浪费和排入外环境的污染物,对社会发展和生态环境均具有明显的正效益。

In response to the energy conservation and emission reduction and recycling economy,we propose a new method of sewage treatment in the industrial park-use wastewater treat wastewater:utilizing alkaline substances in wastewater from enterprise A and consuming hydrogen ions in wastewater from enterprise B;then the Calcium carbonate is added to remove the excess hydrogen;at last,the liquid alkali is added to remove the copper ions and the zinc ions in the wastewater.The optimized method can reduce the amount of hydrochloric acid and Calcium carbonate,reduce the waste of resources and decrease pollutants discharged into the external environment from the source,and it has obvious positive benefits for social development and ecological environment.
