水资源短缺是制约煤化工产业发展的主要瓶颈。实现煤化工过程液体零排放势在必行。各种废水处理工艺已被开发出来，但在实践中还没有一种实现零排放。回用水水质不符合要求，导致生化系统微生物失活，加速换热器腐蚀结垢。这些问题甚至会威胁到生产和运营。目前的水处理装置只是简单地拼凑在一起，导致水质不能令人满意。因此，提出了一种新的水处理指标体系，以确保水质回用和零液体排放。为了建立水处理指标体系，本文着重对水处理全过程进行研究。为了更好地说明，建立了零液体排放的水处理工艺。质量平衡被称为…
The shortage of water resources is the major bottleneck for coal chemical industry development. It is imperative to approach zero liquid discharge for coal chemical processes. Varieties of wastewater treatment processes have been developed, but none of them have yet achieved zero discharge in practice. The water quality of reuse does not meet the requirements, resulting in inactivation of microorganisms in the biochemical system and accelerated corrosion and fouling of heat exchangers. These problems can even threaten production and operation. Current water treatment units are pieced simply together leading to unsatisfactory water quality for reuse. Therefore, a new water treatment index system is proposed for ensuring water quality for reuse and zero liquid discharge. In order to establish the water treatment index system, this paper focuses on the study of the whole water treatment process. For better illustration, a water treatment process for zero liquid discharge is established. A mass balance is cal...
