多年来,松香工厂的洗涤水和废水一直排放至下水道或自然河流与湖泊。最近几年,这个问题在松脂加工行业引起了关心。虽然废水和排放没有因公害而提出警告,也没有危及自然资源,但解决它已越来越重要了。应两个松脂加工厂的请求,我们测定了他们的松脂洗涤水和废水,采用了从水中清除溶解和悬浮物的简单方法,提出了净化废水的步骤。
For years, wash water and waste water from rosin plants have been discharged into sewers or natural rivers and lakes. In recent years, this issue has caused concern in the rosin processing industry. While wastewater and emissions have not been warned of pollution or endangering natural resources, it has become increasingly important to address them. At the request of two rosin processing plants, we measured their turpentine wash water and wastewater using a simple method of removing dissolved and suspended solids from the water and proposed the steps of purifying the wastewater.
